STARCH EFFICIENCY IN WATER TURBIDITY REMOVAL
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2012, Vol 1, Issue 2
Abstract
In this paper, the efficiency of starch as a coagulant aid factor is compared within two ranges of pH i.e. 7 and 8 in water turbidity removal. The experiments were performed in three turbidity ranges 100, 50, 20 NTU and the coagulant was ferric chloride. The volume of ferric chloride in all experiments were 10 mg l-1 and starch in optimum concentration for turbidity of 100, 50, 20 NTU was 0.2 mg l-1, 0.1 mg l-1 and 0.04 mg l-1 respectively. Using starch coagulant aid in turbidity 100, 50, 20 NTU can eliminate 92.4, 86.46, 83,8 % of turbidity in pH of 7, while in pH of 8 it can eliminate 85.44, 81.56, 78.9 % of the mentioned above turbidity, respectively. According to the achieved results, the optimum pH was 7.
