Recent Achievements in Polymer Bio-Based Flocculants for Water Treatment

Due to the large amount of literature on flocculation in water treatment and the narrow aspects of individual published works, our intention is to summarize in one article the latest achievements on the acquisition of new biomaterials for flocculants manufacturing, research methodologies including determination of process efficacy, and future trends in this field.

A review on application of flocculants in wastewater treatment

Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.

Research on a new cationic polyacrylamide (CPAM) with a

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge. Therefore, it is particularly important to develop new and efficient flocculants

A comparison study between bioflocculants and PAM for dewatering of

Natural polymer flocculant possesses an exciting prospect in water treatment due to its non-toxicity, wide source, low cost and biodegradability. In this work, we have successfully synthesized the anionic terpolymer of carboxymethyl cellulose-itaconic acid?sodium alginate (CIS) by microwave-assisted copolymerization.

IOP Conference Series: Earth and Environmental Science PAPER OPEN

The type of monomer used to synthesize the PAM chemical also affects the flocculation effect. Usually, two different cationic monomers, ADAM-MeCl and APTAC, are used in the production of cationic PAM chemical. APTAC monomers are not sensitive to the cationic charge hydrolysis. The most common anionic monomer is sodium acrylate. 3. Pam Dosage of
