(2022-10-11) Lemos, Ana Letícia Barbosa Ferreira; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/3834066130381907
With population growth, utilities have less and less control over the use of water and the production and direction of sanitary sewage in the network. Thus, it is very common to observe in the invoices issued by the concessionaires, the application of tariffs considering the calculation of the volume of sewage assigned as 100% of the supply value, that is, indicating that all water consumed is directed to the sewage system. In practice, this does not occur, as there are consumption points asinfiltration into the soil, evaporation or rainwater sewer system, demonstrating the need for quantification and monitoring so that the tariffs applied based on the precision of the volume spent. In this sense, the individualized measurement system (SMI) of water combined with telemetry is a current technique that presents efficiency in the calculation of the volume of water. Therefore, the objective of the work was to apply the SMI together with telemetry in the club Associação Atlética do Banco do Brasil of Recife (AABB). The study was carried out over a period of 4 months, where the survey of supply points that do not generate sewage was carried out, the installation of the SMI, the installation of telemetry, the monitoring and calculation of the discount to be considered in the invoice. After 3 months of evaluating the results, a total volume of 17,85% was found, demonstrating the importance of reducing the rate and controlling consumption.

The use of wells to obtain underground water resources has become a complementary alternative for human supply. However, over the years, high consumption and anthropic action have contributed to the scarcity of groundwater and its contamination, have contributed to the contamination of groundwater, making it an agent that transmits diseases caused by pathogenic microorganisms from percolation of domestic sewage and/or chemical matter in concentrations that exceed the standards authorized by the Ministry of Health and CONAMA 357/2005, of the Ministry of the Environment. The aim of this study was to analyze the physical-chemical parameters: pH, dissolved oxygen, electrical conductivity, total dissolved solids, salinity, color and turbidity and to evaluate water quality by the Most Likely Number (NMP.100 mL-1) of total coliforms and thermotolerant, based on current legislations. In −1 total, 120 samples were analyzed for physical-chemical characterization and 6 for microbiological, from three wells in the community of Itapuama, located in the city of Cabo de Santo Agostinho - PE. Of the evaluated wells, two did not comply with the quality standard established by Brazilian legislation. The results showed a high concentration of electrical conductivity, low dissolved oxygen and high levels of microbial contamination. These non-conformities can originate from the inefficiency of the neighborhood's sewage system. The third well, since it is a phreatic tubular well, presented good quality water in the studied parameters, being above the limit only in the electrical conductivity parameter.

(2025-03-20) Silva, Adrielly Costa da; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; https://lattes.cnpq.br/2754815465187962
O desperdício de água nas redes de distribuição no Brasil representa um grande desafio para a eficiência do saneamento. Apesar de o país deter 12% da água doce do planeta, a infraestrutura precária e a falta de investimentos em tecnologias de monitoramento e controle agravam esse problema. Diante desse cenário, o presente estudo analisou, por meio de revisão bibliográfica atualizada, as principais causas das perdas de água e as soluções adotadas para mitigá-las. Os resultados indicaram que as perdas podem ser reais, causadas por vazamentos, extravasamentos, variações de pressão e falhas estruturais, ou aparentes, causadas por fraudes, erros de medição e cadastros desatualizados. Além disso, a análise dos índices de perdas mostrou que em 2022, o Brasil perdeu 37,8% da água potável, sendo mais elevadas na região Norte e Nordeste devido à infraestrutura precária e menor fiscalização. Dentre as estratégias mais eficazes para reduzir essas perdas, é possível destacar a setorização da rede, o uso de sensores inteligentes, o controle de pressão e a aplicação de inteligência artificial para monitoramento e gestão da distribuição. Essas estratégias, quando aliadas à modernização da infraestrutura, às medidas preventivas e às tecnologias inovadoras podem aprimorar a eficiência do sistema de abastecimento, além de garantir a conservação dos recursos hídricos no Brasil.
Disruptores endócrinos e seus efeitos na contaminação de recursos hídricos e qualidade da água: uma revisão bibliográfica sobre os riscos ao meio ambiente e saúde pública
(2024-10-01) Lima, Palloma Alves de; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/7650929240255507
Endocrine Disruptors (EDs) are chemical substances that interfere with estrogenic activities in the environment and promote the incidence of diseases. When in contact with the body, these substances cause deregulation capable of damaging and/or inhibiting the functioning of an endocrine organ. In this context, contamination by EDs can occur through several routes, including contact with water, food consumption, and biological transfer. That said, high concentrations of EDs in water cause adverse effects on animal life, such as reproductive and hormonal problems. In turn, in humans, EDs can promote changes in the reproductive system, dysfunctions in the nervous system, and neurobehavioral effects, such as autism. In view of this finding, this paper presents a bibliographic review on the association between EDs and their effects on the contamination of water resources and water quality, especially with regard to the environment and public health, with emphasis on Autism Spectrum Disorder (ASD). The work was developed based on research in the main electronic databases: CAPES, SciELO and Google Scholar Periodicals; within the sample space of 24 years. As a result, cases were observed in which the presence of glyphosate, plasticizers and drugs were associated with speech delay, loss of developmental skills, seizures and diagnosis of ASD. In general, a direct relationship was observed in the vast majority of studies between the interference of endocrine disruptors and the increase in children diagnosed with ASD. In order to mitigate the neurobehavioral effects caused by contamination of water bodies, forms of water treatment to remove EDs were presented.
Estudo comparativo entre os sistemas de drenagem convencional e sustentável para um loteamento no município de Gravatá - PE
(2022-10-07) Santana, Caroline Adriele Mendonça de; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/7891435824185832
As a result of disorderly population growth, increased deforestation and pollution in recent years, cities are experiencing the great challenge of dealing with rain runoff problems. Due to the soil waterproofing, problems such as flooding and inundation resulting from natural events are increasingly frequent, and in addition to it, the lack of planning in cities. To solve this problem, it is necessary to use urban drainage elements that act efficiently in the capture and adequate conduction of rainwater, reducing the negative impacts on the population and the environment. In this context, the present study made a comparative analisys between conventional and sustainable drainage systems for a subdivision in Gravatá-PE. The conventional drainage system was dimensioned with the use of gutters, storm drains, manholes, detention reservoir and culverts. The sustainable drainage system, on the other hand, was designed with partial replacement of waterproofed coatings with green areas, use of interlocked pavements, hollow blocks, infiltration trenches and a detention reservoir with a permeable bed. The results showed that the increase in green area, in addition to providing environmental comfort, also contributed to the reduction of surface runoff, reducing the risk of floods and waterlogging. Besides, by providing greater infiltration of water into the soil, sustainable drainage showed savings in the use of devices. Therefore, the study showed that the adoption of sustainable measures, from the conception to the execution of the projects, can be the solution to the current problems faced regarding urban drainage.

(2023-04-26) Silva, Juliana Lima da; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/1031733290570454
According to the Ministry of the Environment, in Brazil, in 2017, about 55% of the waste produced is composed of organic waste and the current disposal of this waste in the environment has been responsible for deleterious impacts on man and the ecosystem. Composting is one of the most effective means of recycling organic waste, as in addition to being a sustainable way of disposing of this waste, the use of its by-product in the soil can keep acidity levels stable and favor agricultural practices. There are different composting methods, with domestic composting being an advantageous alternative for the treatment of the organic portion of household waste, since the installation of the system and the use of the final compost takes place in the same place where the waste is produced. The final organic compost is a material rich in macro and micronutrients, with satisfactory application, as fertilizer or fertilizer, in horticulture. Organic horticulture is intended for the cultivation of vegetables, legumes, grains, among other healthy foods that contribute to the health and well-being of its users. In this context, the objective of this work was to study domestic composting as an instrument of environmental sustainability and improvement of the quality of life.

Estudo do aproveitamento do lodo oriundo das ETES na construção civil: de rejeito a recurso ambiental
(2024-03-02) Souza, Tatiana Pereira da Silva; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/2336570792811598
A Sewage Treatment Station (ETE) refers to a publicly or privately owned structure used for the treatment of sanitary sewage. The sewage sludge generated in the treatment process presents a high potential risk to public health and the environment. Its final destination also denotes concern, given the large quantity generated. Furthermore, when not managed properly, it can cause serious socio-environmental problems. In this sense, the search for solutions and alternatives that can solve or reduce the environmental problems faced is eminent. Thus, the proposed objective was to study, through a careful literature review, the origin and characterization of STP sludge and its potential in civil construction, based on its application as a supplementary material to mortar, concrete and paving. The work was carried out through research in the main databases: CAPES Periodicals, Google Scholar, Scielo and Scopus; with works published in the last 30 years. As a result, when evaluating the mortar, the most recommended sludge incorporation levels were 10% and 20%. For concrete, replacing fine aggregate or adding cement to sludge presented the levels of 5% and 10% as the most had the best dosage values in the order of 5% to 7%. In general terms, ETE sludge was viable for use in civil construction, demonstrating its potential use as an environmental resource.

In front of the great increase in the generation of urban solid waste, recurrent of the disordered population growth, a composting is taken as an alternative for the treatment of the organic waste fraction. In this context, the objective of this research was to evaluate a domestic composting of solid waste from a residence, using the compost produced in the cultivation of collard greens seedlings and employing domestic composting and the practice of horticulture as a sustainable and productive activity, which induces physical and mental well-being in a pandemic period. The composting process lasted 120 days and was carried out in a designed mini composter. The organic compost produced was used to obtain seedlings of two collard greens species. The sowing was carried out in a tray with fifteen cells, set up in a completely randomized design, with five treatments and three replications. The applied treatments, T0, T1, T2, T3 and T4,corresponded, respectively, to 100% soil; 75% soil and 25% fertilizer; 50% soil and 50% fertilizer; 25% soil and 75% fertilizer and 100% fertilizer. They were avalueted: germination time, leaf length, leaf width, number of leaves, seedling height, root length and stem diameter. Treatments T2, T3 and T4 showed the best performances, with treatment T2 being the one with the best results for Brassica oleracea var. Costata and treatment T3 for Brassica oleracea var. Acephala. In addition, the study was assessed as adequate by the process participants, as it aroused interest, sustainable learning and productive routines, directly influencing the maintenance of well-being during pandemic period
Impacto socioeconômico da compostagem doméstica em uma comunidade indígena no município de Baía da Traição/PB
(2022-10-10) Padilha, Francis Bezerra; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/7935712126036066
The generation of waste, of all its typologies, represents a problem for the whole society, not being restricted only to Brazil. Its disposal and destination have been objects of study, in order to minimize and/or solve the impacts caused by the mismanagement of these wastes. Organic matter represents a large portion of urban solid waste in Brazil and, therefore, its treatment is essential for the reduction of material to be sent to landfills or to another destination. An environmentally correct destination is the use of organic fertilizer resulting from composting in agriculture. Thus, the present study sought to evaluate the socioeconomic impact of home composting in an indigenous community in the municipality of Baía da Traição/PB. The residues used in the process were cassava peel and dry cashew leaves in a C/N ratio of 30:1. The resulting organic fertilizer was used in the planting of lettuce, reaching the production of 350 feet in one cycle; and a sales profit of R$1050.00 reais. This practice can strengthen and promote local development in the indigenous community, making the circular economy from agriculture. On the other hand, the work sought to influence the environmental awareness of the population by offering a lecture on the importance of home composting in the social context. In this way, the positive impact of composting on the community was observed, either in the financial aspect or in the educational aspect.

The principle of sustainability goes beyond solving immediate problems, it represents an innovative approach to interacting with the environment through new construction practices. In this sense, several sustainable techniques have emerged as promising alternatives for the production of works. They are: sustainable drainage, collection and use of rainwater, photovoltaic panels and green facade. In this context, the present study aimed to carry out a careful bibliographical review regarding the application of these technologies in the current scenario of civil construction and their application in a case study, carrying out a financial approach through two scenarios: assessment of costs with application of technologies and assessment of costs without applying them. The case study was applied in a local unit aimed at meeting the public in a specific community. After evaluating the results, it was observed that the technologies mentioned are promising in the country, from a social, environmental and economic point of view. Furthermore, in the case study, the application of technologies resulted in an overall savings of 71.53% over the conventional costs of the project, demonstrating the financial viability for the civil construction scenario.
Influência da adubação com lodo do tratamento de esgoto doméstico no cultivo de feijão e milho
(2021-03-01) Lyra, Gabriel Rigaud Figueirôa; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/3958782513733383
In the biological stage of sewage treatment, part of the organic matter degraded by microorganisms is converted into biomass, which constitutes the biological sludge or secondary sludge. Currently, the most used alternative for final disposal of sludge in Brazil is sending it to landfill, due to the low operational cost involved. However, this technique does not include the nutritive and/or energetic potential of the sludge. That said, this study evaluated the use of sludge from domestic sewage treatment in the cultivation of cowpea bean seedlings (Vigna unguiculata (L.) Walp., Cultivar IPA 206) and corn (BRS Gorotuba), compared to the use of chemical fertilizers. The experimente for each culture was conducted in a greenhouse and set up in a completely randomized, with 4 treatments and 3 repetitions, using pots containing 10 kg of soil. The two cultivations were carried out in parallel. The 4 treatments applied were: without fertilization, chemical fertilizer (NPK), lime sludge and composted sludge (T0, T1, T2 and T3, respectively). Among the performance parameters analyzed, in both crops, T1, T2 and T3 treatments presented plants with equivalent physical aspects (plant height and stem diameter). With regard to beans, the treatment T3 stood out for the amount of pods per plant, being about 125% higher than others, and for the higher performance in the weight of 100 beans (29.67g). For corn, treatments T1, T2 and T3 achieved equivalent performance. However, T3 obtained the highest numerical averages in all parameters of this cultivation. Finally, it was observed that the treatment with the greatest influence, in both crops, was T3, reaffirming the great potential of composted sludge

Mensuração do retrabalho e análise dos seus impactos em um empreendimento da construção civil
(2024-10-03) Moura, Raquel dos Santos; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/8570705550619688
With the increase in activities in the construction industry, one of the sectors that consumes the most natural resources and generates the greatest environmental impacts, there has been a growing need to seek more sustainable construction methods. In this pursuit, one way to promote better resource use is to ensure that processes do not need to be redone, i.e., to avoid rework. The present study proposed a case study aimed at measuring rework, analyzing its impacts, and defining corrective actions in a construction project. A total of 34 rework incidents and their 486 occurrences were analyzed for the stages of sealing, installation and finishing. Rework activities were mainly generated by failures in planning, scheduling, engineering, and supervision. These situations resulted in an additional cost of approximately 301,000 reais for the project. Based on the findings, a checklist was created that included preventive and corrective measures to reduce rework activities, with actions to be implemented such as allowing more planning time before the execution of activities, ensuring more assertive communication between engineering and suppliers, and training employees whenever there is a change in sector.
Projeto de reuso de água pluvial em habitação popular para fins não potáveis
(2019-12-12) Cruz, Ana Vitória de Souza; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/1049768443014317
Strong population growth and urbanization have led to increased drinking water consumption. This factor, coupled with irresponsible use and pollution of water sources, has contributed to a considerable water crisis. Brazil is a privileged country, as it has 12% of the world's freshwater, but due to poor distribution, there are regions of the country where water availability is low, such as the Northeast of Brazil that faces severe scarcity crises most of the year. Therefore, the search for sustainable policies that provide solutions to this problem and at the same time make the population aware of the importance of conscious use of water is necessary. Within this context, the reuse of rainwater becomes a viable alternative, easily applied, which provides the preservation of the environment. Therefore, the present work elaborated a popular housing project in Recife based on the city's Master Plan and designed a Rainwater harvesting System for this dwelling, according to NBR 10844 (1989). In the project, the rainwater was captured only by water from the roof, which enough to meet the house reuse needs, as the city has a high rate of rainfall. The materials used in the installation of the collection system were low cost and simple to apply, where the implementation project presented a much lower cost than the total value of residential construction, besides representing an excellent alternative for environmental awareness and treated water saving
Qualidade da água de poços artesianos associada ao perfil socioeconômico na comunidade de Itapuama, Cabo de Santo Agostinho, Pernambuco
(2022-06-03) Borba Júnior, Adriano Cabral; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/2480565768387290
The use of groundwater is quite widespread in Brazil. Through artesian wells it is possible to find a regular and economically viable supply alternative. However, these waters are not inert to human actions, since in many studies pathogenic agents were found in these water bodies. The objective of this study was to correlate the quality of water from artesian wells to the socioeconomic profile of the population in the community of Itapuama, Cabo de Santo Agostinho, Pernambuco. To evaluate the water quality, seven shallow and deep water wells named A, B, C, D, E, F and G were selected, according to the probable susceptibility to contamination. Physicochemical analyzes of pH, electrical conductivity, dissolved oxygen, colorimetry, salinity, total solids, turbidity were carried out and for the microbiological analyzes were total and thermotolerant coliforms. The assessment of the socioeconomic profile was carried out with relevant public and non-governmental bodies in the municipality. In these meetings, parameters of occupation, family income, education level and selective garbage collection were analyzed. The results showed a direct correlation between the water quality and the socioeconomic factors of the sub-regions of the community of Itapuama, being evidenced in the Map of water quality x socioeconomic profile.
Tecnologias e estratégias utilizadas para controle e economia de água nos principais setores de consumo hídrico no Brasil: uma revisão atualizada
(2023-05-02) Soares, Gustavo Costa Lima; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/5651077919700775
Water is a finite resource, of fundamental importance for the maintenance of human life. Its use over time has become an important demand in various sectors of society. According to the National Agency for Water and Basic Sanitation (ANA), the sectors that consume the most water in Brazil are: Agriculture, Urban Supply, Rural Supply, Industry, Animal Drinking, Thermal Power Plant and Mining. With this, planners and management entities have sought to generate alternative solutions for better management of water resources, so that it is possible to optimize its use and consequently reduce its waste. Thus, this work presents, based on an updated bibliographic review, the main technologies and strategies adopted by the consumption sectors to mitigate the control and save water. Drip irrigation and plant genetic modification are technologies that stand out in the agricultural sector; the reuse of water in industry and the installation of water-saving mechanisms in domestic appliances also stand out as promising technologies, as well as the reuse of rainwater and the implementation of integrated crop-livestock-forestry systems in rural areas. In general, it is observed that each sector has its own challenge, converging in the search for technologies and innovations that manage consumption, combat scarcity and reduce water waste.
