water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

Because of the low critical free adsorption energy of polymer chains on the particle surfaces, in the order of about 0.3 kT per segment, 6 the rate of polymer adsorption equals the rate of polymer loss from the solution, which explains the significant role of mixing in flocculation.

Drinking water treatment by stepwise flocculation using

Flocculants are mainly divided into three distinct classes: inorganic coagulants, synthetic organic polymeric flocculants, and composite flocculants. Traditional flocculants, such as polyaluminum chloride (PAC) or its polymer, are the most widely used inorganic coagulants in water treatment plants due to their low price, low toxicity, and ...

Continuous low dosing of cationic polyacrylamide (PAM) to

Overall, this study demonstrated that addition of low levels of the chemical flocculant (e.g. cationic polyacrylamide) to the HRAP effluent can greatly improve algal solid removal (at least 50%) with a minimum chemical cost (¡«$0.05 NZD/m 3 of wastewater).

A cationic polyacrylamide dispersion synthesis by dispersion

These polymers are used as retention and drainage aids in papermaking, as flocculants in wastewater treatment, and as stabilizers for emulsion polymerization in cosmetics (Yan 1998). For the same applications, high molecular weight polyacrylamide (PAM) has been widely used because of its effectiveness and low price, but it is nonionic.

cationic starch: an effective flocculating agent

Cationic starch: an effective flocculating agent

Starch is an effective polymer for creating reactive cationic moieties using a quaternary ammonium compound. The reasons we used starch as a raw material for cationic flocculants are its biodegradability and its relatively low price. In this present investigation, various grades of cationised starch have been synthesized by using a cationic ...

optimizing the flocculation effect of cationic polyacrylamide

Optimizing the Flocculation Effect of Cationic Polyacrylamide

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM. In this paper, the optimal flocculation conditions of a novel CPAM were ...

Removal of emulsified oil from water by using recyclable

More than 95.0% oil was removed at the composite usage of 50 mg/L polyaluminum chloride (PAC), 10 mg/L polyacrylamide (PAM), and 50 mg/L Fe 3 O 4 (Tang et al., 2019). Moreover, cationic polyacrylamide (CPAM) was grafted onto Fe 3 O 4 to prepare magnetic flocculant (CPAMF) for high turbid water treatment (Liu et al., 2020a, Liu et al., 2020b ...
