Oxigênio dissolvido (OD), demanda bioquímica de oxigênio (DBO) e demanda química de oxigênio (DQO) como parâmetros de poluição no ribeirão Lavapés/Botucatu - SP
(Editora Unesp, 1997-01-01)
Oxigênio dissolvido (OD), demanda bioquímica do oxigênio (DBO) e demanda química do oxigênio (DQO) foram utilizados como parâmetros para se avaliar o grau e capacidade de autodepuração do ribeirão Lavapés, que atravessa a ...
Recovery and Recycling of Silver from Residual Solution Derived from Determination of Chemical Oxygen Demand
(Brazilian Chemical Soc, 2015-07-01)
Analytical methodologies that generate wastewater rich in potentially recoverable silver ions are commonly used to determine chemical oxygen demand (COD). The chemical residue resulting from these assays is classified not ...
Application of microbial fuel cell technology for vinasse treatment and bioelectricity generation

Objective: Our study evaluated the performance of different two-chambered microbial fuel cell (MFC) prototypes, operated with variable distance between electrodes and Nafion membrane and specific inoculum concentration, ...
Production and use of microbial biomass helping sustainability in tilapia production chain
(2019-09-01)
In this study, the cultivation of Rubrivivax gelatinosus in fish industry effluent was carried out to cause the depollution of the by-product and generate a protein–carotenoid-rich biomass suitable to be used in tilapia ...
Performance Evaluation of First-Order Hydraulic Models for COD Removal in Horizontal Subsurface-Flow Constructed Wetlands
(Asce-amer Soc Civil Engineers, 2017-10-01)
The aims of the present study are to verify the performance of four first-order hydraulic models and identify the model that best described the kinetics of the chemical oxygen demand (COD) removal in constructed wetlands. ...
Membrane technologyfor the treatment of fish industry effluentTecnologia de membranas no tratamento de efluente de indústria de pescado
(2018-01-01)
Membrane filtration emerges as an alternative for the treatment of fish processing effluent. The aim of this work was to verify the ability of membrane filtration on reducing the pollutant load of tilapia processing effluent. ...
Ultrafiltration for the recovery of proteins from surimi washing water
(Sociedade Brasileira de Ciência e Tecnologia de Alimentos, 2020-10-09)
The aim of this study was to evaluate the efficiency of the ultrafiltration process (UF) in the cleansing treatment of the tilapia surimi washing water and in the recovery of components. After producing surimi, the water ...
