Abstract
|
|
|
Many factors, such as, kind and quantity of coagulant, charactor of water, pH of water, time of mixing, and violence of agitation, influence the coagulation of turbid and coloured waters.
And every water treatment plant should carry out laboratoru control to proper coagulation treatment in advance.
The object of this laboratory study is to investigate the chemical coagulation and determine the optimum coagulant doses using jar test. The results obtained were as follows;
1. The optimum dose of alum was 75 ㎎/ℓ for treatment of water having 32 units of turbidity. The ratio of alum dose to turbidity of water was 2.34.
2. The optimum pH was 6.5.
3. Magnafloc LT 24 was best and most economic among four coagulant aids used. The optimum dose was 0.5 ㎎/ℓ of Magnafloc LT 24 plus 10 ㎎/ℓ of alum.
