Comparative Study on Coagulation Process for Vellore Municipal Drinking Water Using Various Coagulants
نویسندگان
چکیده
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 operational parameterspH and coagulant dosages were optimized. Further the treatment efficiency was evaluated on the basis of turbidity, total dissolved solids (TDS), organic content in terms of UV absorbance at 254 nm and microbial contamination (MPN for total coliform) for all three coagulants. Best removal efficiency was achieved near neutral pH with dosages of 45mg/L and 25mg/L for alum and ferric chloride, respectively.However, the Moringaoleiferacould not found effective in removing targeted contaminants.

The efficiency of various polyaluminium chloride coagulants (PACls) was compared to the efficiency of aluminium sulfate (alum) in the coagulation-flocculation process preceding direct filtration in drinking water treatment. The comparative study consisted of two separate yet complementary series of experiments: the first series included short (5-7 h) and long (24 h) filter runs conducted at a p...

Coagulation process is an essential part of drinking water treatment operations. The jar test is a widely-used laboratory procedure to determine the quantity of coagulation chemical dosages for water treatment plants. However, the test is not effective for real-time control of this process due to the nonlinear behaviour and rapid variations of water quality parameters. In this study, empirical ...

Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

Problem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity wa...
