micropoluentes, membranas. ABSTRACT. The number of production facilities for potable and industrial waters through polimeric membranes has constantly increased in the last few years. Recent applications in the water industry involves Microfiltration (MF), Ultrafiltration (UF) and low pressure membrane processes. The UF process is spreading very fast in the water treatment field. About tirthy (30) water treatment plants of this kind, with capacities ranging from 100 to 50.000 m3/day, have…

respectivamente. Ademais, após 15 dias de operação, o sistema estabilizou com fluxo permeado elevado: 43 L/m².h. Palavras-Chave: Biorreator à Membrana, Tratamento de Efluentes, Reuso, Curtume. XIII ABSTRACT The preoccupation with the quality of water resources is intensifying studies about advanced technologies for wastewater treatment. A promising technology in Brazil is the membrane bioreactors (MBR), due its capacity to operate with high application rates and may also…

the purge water from the Refinery Duque de Caxias cooling towers by reverse osmosis (RO) was evaluated. The oil industry consumes huge volumes of water in the industrial refining operations and, due to the increasing demands and changes in the environmental legislation, reinforcing the reuse of it, the purge waters present high flows and chemical composition characteristics that make them proper for treatment for reuse. The RO process has two fundamental advantages for desmineralized…

Para estes estudos empregou-se o teste t de Student pareado. No presente trabalho buscou-se avaliar a estabilidade e repetibilidade do método colorimétrico por ácido vanadomolibdofosfórico (norma 4500-P C, Standards Methods for the Examination of Water and Wastewater) para a determinação de fósforo em efluente do setor laticinista. MATERIAIS E MÉTODOS Para a determinação de fósforo total foram necessárias adequações da metodologia 4500-P C. Vanadomolybdophosphoric Acid…

conductivity is a suitable technique to evaluate the dispersion of oil refinery wastewaters, since they have high conductivity and for this reason there is a strong contrast between the values of the wastewater and the ambient background. Furthermore, other water quality parameters had a dispersion behavior similar to that shown by the conductivity. The dispersion plume generated by the computational simulator showed high concordance with the field data. In this manner, computational…

to establish the dosage of moringa seed extract and sedimentation time most suitable to treat wastewater generated in the processing of cashew nuts in Mossoró-RN. Samples of wastewater were collected and sent to the Laboratory Analysis of Soil, Water and Plant UFERSA. In trials were analyzed sedimentation times seven (0, 1, 2, 3, 4, 5 and 6 h) in three replicates. While, in defining the dose of extract of moringa more efficient six concentrations were used (0, 250, 500, 750, 1000 and 1250 mg

Green Chemistry in Water Treatment: Use of Coagulant Derived from Acacia mearnsii Tannin Extracts Abstract: News coagulants for water and sewage treatment are synthesized trough the chemical transformation of tannin extracts. Tanfloc® is a cationic polymeric coagulant produced from tannin extract of Acacia mearnsii. In this paper we are supporting the use of cationic polymeric coagulant for treatment of polluted water instead of aluminum or iron salts to support the sustainable water…

Abstract - Water is a vital limited and finite resource on earth and is necessary for economic and social development and for the environmental sustainability. However, there are in brasilian semiarid zone, one thousand of dams and salinized wells, without utilization and recently, with the brackish water desalination process implanted in the region, the saline reject has gona throw in lakes without control. This review has the purpose to show some possibilities to use this helpless…
