A physicochemical treatment (coagulation–flocculation) was applied to a slaughterhouse wastewater, using anionic polyacrylamide as coagulant aid to improve the settling velocity of the flocs formed with the coagulants used: ferric sulphate, aluminium sulphate and polyaluminium chloride.
About 97% of these are petroleum additives, 89% are paper chemicals, and 68% are plastic auxiliary agents. A wide variety of additives polyacrylamide options are available to you, such as coating auxiliary agents, water treatment chemicals, and paper chemicals.
3.1.- Determination of the optimal coagulant aid dose. The experiments were performed with a fixed coagulant dose with respect to the metal ion (500 mg Me3+ l-1). Prior to the addition of the coagulant aid, experiments were carried out with different pHs in order to determine the optimal pH values for performing the experiments.

This is the first attempt to use cationic polyacrylamide (PAM) as coagulant aid with titanium tetrachloride (TiCl 4) to improve the coagulation performance and floc properties. Coagulation–flocculation treatment was applied to simulated water (with fulvic acid (FA) as model organic matter) for both coagulation behavior investigation and floc ...
