Characterization of product
- Having high molecular weight HSD is outstanding to neutralize surface currents of particles in colloid state
- With functional group HSD exhibits efficiency in decolorizing
- The effect of pH in treatment is almost not ; coagulant pH is wide
- Though the water quality change, stability treatment is maintained
- HSD can decrease the usage of inorganic coagulant
|
◐
Advantage of HSD
- It is water soluble as emulsion form
- HSD increase water quality sinkability by structuring floc to form insoluble complex with materials(color, pigment, paper, leather, food)
