|
If use alum that has polyelectrolyte annexation in the Coagulation process, the effectivenesses can be seen like below.
1. In case of the raw water’s tubidity being over 50 NTU, it can reduce much alum dosage with utilizing the alum that N-100 pwg (0.08㎎/ℓ∼0.01㎎/ℓ) is added to it in a small amount. 2. Also when we add polyelectrolyte (0.02∼0.08㎎/ℓ) following as the raw water tubidity, it can find the water quality be find and see the settling Velocation encreased as floc size’s making a big scale. 3. Depending on the above experimental results, if we use the polyelectrolyte annexation when producing 30㎥ water a day, it can consider the possibility of the reduction rate like as the tubidity of raw water be 10% in 50NTU, and 60% in 1000NTU.
