Análise de econometria de dois sistemas naturais de tratamento de água residuária na suinocultura
(2008-12-01)
The aim of this work was to develop a detailed econometric analysis to compare a constructed wetland system - combined model, and a waste stabilization pond system - facultative pond, as a function of six different sizes ...
Emprego de biofiltro de pedra para remoção de microalgas e sólidos suspensos de efluentes de lagoas de estabilização
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-graduação em Engenharia SanitáriaSaneamento Ambiental; Meio Ambiente; Recursos Hídricos e Hidráulica, 2014-02-28)
This research evaluated the microalgae removal produced in a
stabilization pond system using biofilters as post-treatment, besides
characterizing the effluents of stabilization ponds and filters ...
Diagnóstico operacional de lagoas de estabilização
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-graduação em Engenharia SanitáriaSaneamento Ambiental; Meio Ambiente; Recursos Hídricos e Hidráulica, 2007-05-07)
This work intends to develop an approach based through scientific criteria in the operational diagnosis of ponds of stabilization, starting from analyses accomplished in loco and in laboratory of 78 systems of sewer treatment ...
Removal of faecal coliform in high pH ponds using rapid growth alga biomass
(1991)
A simple device for an efficient waste water treatment is described. The procedure uses a massive microalga culture as a source of OH-, which increases the pH of the medium killing the bacterial population. In the device ...
Model based analysis of the growth kinetics of microalgal species residing in a waste stabilization pond
(2017)
BACKGROUND: In this study the growth kinetics of Chlorella and Scenedesmus, isolated from a Waste Stabilization Pond were investigated under different conditions of light intensity and temperature. Experimental data were ...
EFFICIENCY OF BIOLOGICAL TREATMENT FOR THE REMOVAL OF TOTAL AND THERMOTOLERANT COLIFORM BACTERIA FROM DOMESTIC SEWAGE
(Univ Federal Uberlandia, 2016-11-01)
Researchers around the world have focused their efforts on devising combinations of technologies that are not only economically feasible but also effective in mitigating the impacts caused by wastes containing pathogens ...
Eficiência do tratamento biológico na remoção de coliformes totais e termotolerantes em esgoto humano
(2016-11-01)
Researchers around the world have focused their efforts on devising combinations of technologies that are not only economically feasible but also effective in mitigating the impacts caused by wastes containing pathogens ...
Influência da estratificação térmica no volume útil e no comportamento hidrodinâmico de lagoa de estabilização: determinação experimental e teórica
(ABES, 2009)
Lagoas de estabilização localizadas em regiões com variações elevadas de temperatura ao longo do dia tendem a apresentar estratificação térmica, um fenômeno que altera o volume útil da lagoa. Neste trabalho, apresentam-se ...
