Estratégias operacionais para o envio de lodo aeróbio para adensamento e estabilização em reatores UASB : estudo de caso de uma estação em escala plena
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA SANITÁRIA E AMBIENTALPrograma de Pós-Graduação em Saneamento, Meio Ambiente e Recursos HídricosUFMG, 2020-02-28)
The present work sought to evaluate, in a full-scale WWTP made up of a UASB reactor, post-treatment by trickling filters (TF) and dehydration system with drying beds, the effect of different strategies for sending aerobic ...
Heavy metals: The main factor limiting the agricultural use of sewage sludge
(2017-01-01)
Heavy metals occur naturally in rocks and soils being natural constituents of the Earth's crust that are rarely toxic. The excess heavy metals in soil originate from other sources, which include sewage improper stacking ...
Performance and biological indicators of a laboratory-scale activated sludge reactor with phosphate simultaneous precipitation as affected by ferric chloride addition
(Elsevier Science SA, 2010-12)
Iron-base coagulants are widely used for the phosphorous removal from wastewaters. Coagulants may be applied on the secondary treatment (simultaneous precipitation); however, coagulant excess may alter the biological ...
