Comparative Study on Coagulation Process for Vellore Municipal Drinking Water Using Various Coagulants
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 1
Abstract
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 parameters- pH 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.
