Water Soluble Polymer Flocculants: Synthesis

Cationic flocculants are normally used to flocculate negatively charged particles, and are used in wastewater and sludge treatment, paper production, oily water clarification, textile industry, paint manufacturing, dairy processing, and biotechnology. Compared to nonionic monomers, cationic monomers are less accessible and stable.

    Jun 25, 2015 · Xylan is a part of hemicelluloses of woody materials and can be converted to value-added products such as flocculants for the textile industry. To assess the production of flocculants from hemicelluloses of woody materials, xylan was selected as a model and rendered cationic via copolymerization.

    Jun 25, 2015 · Xylan METAC Flocculant Azo-dye wastewater 1. Introduction Xylan is the main hemicellulose of hardwood and a part of the hemicelluloses of softwood and nonwoods. It consists of xylose units that are linked by (1–4)-β linkage.

A Novel Wastewater Treating Material: Cationic Poly

A cationic polymer flocculant or flocculent causes tiny particles to come together. When this happens they build size into a much larger “floc” particle. Then gravity takes over and drops the “floc” masses to the bottom of the tank. The treatment tank is often called a clarifier or thickener.

Consequently, cationic-type polymer ?occulants which are quite effective in sludge dewatering were developed [3, 4]. However, as organic matter contents in the sludge increased, cationic-type polymer ?occulants could not work effectively in sludge dewatering.

The Use of Cationic Polymers as Primary Coagulants in Water

Abstract. The removal of natural organic matter (NOM) from drinking water supplies can be achieved with cationic polymers, used here in jar tests on simulated waters made from concentrates of humic substances. In applying organic polymers to the removal of UV absorbing compounds (used as a measure of trihalomethane precursors), a reservoir
