The efficiency of Moringa oleifera (MO) seeds as a natural coagulant in the coagulation/flocculation process, followed by nanofiltration (NF) for the removal of cyanobacterial cells and cyanotoxins is investigated. "Synthetic water" prepared for the tests comprised de-ionized water with an inoculum of microcystis protocystis cells to obtain turbidity within(More)
The objective of this study is to investigate the impacts of anionic polymer as a flocculant aid on the coagulation/flocculation performance with a saline solution of Moringa oleifera as a coagulant to provide larger flocs and decrease the time sedimentation. For the tests, raw water was used from Pirapó River Basin (Maringá, Paraná, Brazil). Optimization(More)
The objective of this study was to evaluate the applicability of tannins natural coagulants, Tanfloc SG and SH, in coagulation / flocculation process for clarification, as post-treatment of effluent from a dairy industry aiming its reuse. Determined pH and optimal dosage of coagulant activity through jar test, in dosages ranging from 10 60 mg.L-1 and pH(More)
