Two coagulants, aluminum sulfate and ferric chloride, were tested to reduce natural organic matter (NOM) as a pretreatment prior to polyvinylidene fluoride (PVDF) microfiltration (MF) membranes for potable water treatment. The results showed that the two coagulants exhibited different treatment performance in NOM removal. Molecular weight (MW) distributions of NOM in the tested surface raw wate...

background; turbidity removal using inorganic coagulants such as iron and aluminum salts in water treatment processes causes environmental and human health concern. historically, the use of natural coagulant to purify turbid water has been practiced for a long time. recent research indicates that descurainia sophia seed can be effectively used as a natural coagulant to remove water turbidity. m...

The present study is focused to optimize the coagulation process for treatment of water sourced from the Palar River Basin and supplied to the Vellore Municipality. The research was progressed to evaluate the water treatment efficacy of natural coagulant i.e. moringaoleiferaseed, available locally in abundance, as well as conventional coagulants viz. alum and ferric chloride. Primly the basic o...

Landfill leachate may cause environmental problems if it is not properly managed and treated. An appropriate treatment process of landfill leachate often involves a combination of physical, chemical and biological methods to obtain satisfactory results. In this study, coagulation-flocculation was proposed as a pretreatment stage of partially stabilized landfill leachate prior to submerged biolo...

Flocculation with titanium tetrachloride (TiCl(4)) and titanium sulfate (Ti(SO(4))(2)) was investigated in terms of different coagulant doses, pH, turbidity, dissolved organic carbon (DOC), UV-254, colour, zeta potential, particle size and molecular weight distribution. The two coagulants were compared with the commonly used coagulants such as ferric chloride (FeCl(3)) and aluminium sulfate (Al...
