Coagulation-flocculation constitute the backbone process in most water and wastewater treatment plants. This study focused on determining optimum coagulant dose for moringa oleifera seed extract, zeolite, ferric chloride, chitosan aluminium sulphate coagulants through coagulation, flocculation sedimentation process. It also ascertain which has potential higher removal of Cd, Cu, Fe, Mn, Pb Zn. ...

Fifty patients with iron-deficiency anaemia were treated by total-dose infusion of iron-dextran. The therapeutic response was satisfactory in all cases. No severe systemic side effects occurred. In ten patients in whom detailed investigations were made there was no change in erythrocyte sedimentation rate or blood coagulation nor was there evidence of haemolysis following the irondextran infusi...

Coprecipitation-adsorption plays a significant role during coagulation-flocculation-sedimentation (C/F/S) of antimony (Sb) in water. This work uses Box–Behnken statistical experiment design (BBD) and response surface methodology (RSM) to investigate the effects major operating variables such as initial Sb(III, V) concentration (100–1000 µg/L), ferric chloride (FC) dose (5–50 mg/L), pH (4–10) on...

Although superfine powdered activated carbon has excellent adsorption properties, it is not used in conventional water treatment processes comprising coagulation–flocculation, sedimentation, and sand filtration (CSF) due to concerns about its residual treated water. Here, we examined the production fate of very fine particles with lacking charge neutralization as a source filtrate after CSF tre...

The city of Tulear is undergoing environmental degradation. wastewater heavily polluted, the average values observed for biological oxygen demand (282,347 ± 76,907 mg.L-1), chemical (579,302 161,102 and suspended solids (859,114 816,707 mg.L-1) are above standard discharge values. This study allowed us to design a treatment system make technical, economic, social assessment plant. Thus, method ...
