Sanya, Hainan polyacrylamide plant sold by polyacrylamide flocculant sewage treatment, the best PH is generally neutral or slightly alkaline, so the best time to use flocculant PH to adjust it, to prevent damage effect .

In PH 10, when the processing speed up significantly faster, settling velocity faster, larger floc. By starch sedimentation experiments to look at the impact of polymer flocculant and PH. When adding a single modified starch, turbidity and COD effects except in alkaline conditions, slightly better than the weakly acidic conditions; when the presence of ferric chloride coagulant, turbidity removal in alkaline conditions slightly better than the weak acidic condition; and COD removal efficiency of the opposite effect under weakly acidic conditions slightly better than weakly alkaline conditions; in terms of turbidity and COD removal, little impact modified starch that is different PH values, but When the presence of an inorganic coagulant, the coagulation effect PH value thereof is influential. Through our continuous experimentation, coupled with practical experience concluded under acidic conditions, for individual use such an organic polymer flocculant polyacrylamide; and in the neutral or alkaline conditions, inorganic aggregating agent and with the use of organic polymer flocculant obvious. According to this law can save the dosage of flocculants to reduce costs.
