Water Soluble Polymer Flocculants: Synthesis

For the sake of our discussion, we chose to classify flocculants in three major categories: i) synthetic flocculants, ii) natural/bio flocculants, with a separate category dedicated to iii) stimuli-responsive flocculants.

Jul 14, 2021 · 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

The addition of a polymeric flocculant allows for the destabilization of suspended colloidal particles, and thus significantly increases their sedimentation rate. Polymeric flocculants are generally divided into four categories, which include non-ionic, cationic, anionic, and amphoteric polymers.

Flocculation of kaolin particles with cationic lignin polymers

The most commonly used flocculants for soil conditioning are polyacrylamide, carboxymethyl cellulose (CMC), and polyanionic cellulose (PAC). Soil conditioning by flocculants is used mainly for EPB shield tunnelling in water-rich ground. When the permeability of the soil is large, water spewing is prone to happen at the outlet of the screw conveyor.

Principles of action of polymeric flocculants - Kitchener

Modern flocculants have a high degree of polymerization (e.g. c. 50 000) and an extremely extended configuration when dissolved in a favourable solvent; this factor explains qualitatively some of the peculiarities of flocculation by polymers and indicates the need for rational control of their use if optimum results are to be achieved. It is

Principle of Flocculation by Polymer Flocculants Small amounts of polymer ?occulants can increase aggregates of particles in wastewater. Two mecha-nisms of aggregation are known: charge neutralization (bridging via electrostatic patch interactions, electrostatic bridge based on point charges) and cross-linking adsorption (polymer bridging) [7].

Flocculants, or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles.

Flocculants are commonly used with coagulants and are a substance that helps the clumping of fine particles into a "floc", especially in the treatment of wastewater. Flocculation is the process in which colloids — low-diameter particles that affect water's color or turbidity — are suspended in the form of loosely clumped particles called flocs.

Flocculation increases the efficacy of depth filtration

The efficacy of flocculation for any given process depends on the nature and concentration of the particulates in the feed stream, the concentration, charge density and length of the flocculant polymer, the shear rate, the properties of the feed stream (e.g. pH and ionic strength) and the properties of the target products.
