Black water flocculant forms foamy floating substances after dissolution
Thread Content
What causes the white foamy substances to form after the Blackwater flocculant is dissolved? The flocculant solution has no viscosity; the foamy suspension has low viscosity, is very light in weight, and has a high foam density.
1\ Is the mixing uniform? 2\ Is the water used soft water? 3\ Is the concentration appropriate?·
Greywater flocculants are generally cationic polyacrylamide, which has poor solubility. Under normal circumstances, the concentration should be 0.1%, and clean water must be used. Moreover, never add the flocculant all at once. Pour it in calmly and quickly along the edge of the vortex created by stirring. Continue stirring until the polyacrylamide is completely dissolved.
Did you find out the reason later on?
