Biopolymer-based flocculants: a review of recent technologies

Biopolymer-based flocculants have become a potential substitute for inorganic coagulants and synthetic organic flocculants due to their wide natural reserves, environmental friendliness, easy natural degradation, and high material safety. In recent years, with more and more attention to clean technologies, a lot of researches on the modification and application of biopolymer-based flocculants

Preparation and Flocculation Performance of Polysilicate Aluminum

A composite flocculant (PSAS-CS) consisted of cationic starch (CS) and polyaluminum silicate (PSAS) was prepared and used for the flocculation of simulated water samples. The morphology and structure of PSAS-CS were characterized by X-ray diffraction, scanning electron microscopy, and infrared spectroscopy.

Recent Achievements in Polymer Bio-Based Flocculants for Water Treatment

The flocculants, designed for coal slime water treatment, were characterized using the FTIR, XRD and SEM methods. It has been shown that water turbidity was reduced by ~97% and ~94%, while COD removal was ~78 and ~74% in the presence of Fe 3 O 4 -chitosan-cellulose and Fe 3 O 4 -chitosan-biochar, respectively.

Water | Free Full-Text | Optimizing the Flocculation Effect of Cationic

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

A Novel Hyperbranched Polymeric Flocculant for Waste-Water Treatment

Especially, cationic polyacrylamide (CPAMs) one of the most widely applied polymer flocculants has exhibited high flocculating efficiency in water treatment [6,7,8,9]. Although linear CPAMs show good application performance in water treatment, the further improvement in their flocculating efficiency is still anticipated because of their coil confirmation, intra- and intermolecular entanglement
