Generally speaking, this phenomenon is caused by the addition of too much flocculant. In general, do not overadd polyacrylamide flocculant. Polyacrylamide manufacturers found that the polymer flocculant in aqueous solution if the concentration of more than 5%, is very easy to form a gelatinous material.Under normal circumstances, flocculants will be used to flocculate and enter the flocculation group. However, if the concentration of polymer materials is too high, the molecules are prone to settlement and adhesion. If part or all of the polymer material does not function, automatic condensation. If added in excess, the excess polymer material will slowly coagulate.
