    Flocculants - an overview

    In wastewater treatment, polyacrylamide-based flocculants are commonly used. Because they can contain potentially toxic acrylamide residues, flocculants based on natural biopolymers are preferred over synthetic polymers. An effective biopolymer flocculant for harvesting microalgae is chitosan, which is prepared by deacetylation of chitin.

    Polymer Flocculants - Boiler, Cooling and Wastewater

    Polymer flocculants used in wastewater treatment are chemical substances whose molecules have high molar masses and are composed of a large number of repeating sub-units. There are both naturally occurring and synthetic flocculants that are commonly used in the treatment of wastewater for solids/water separation and settling and are commonly

    Polyacrylamide is a linear polymer comprised of monomers unit with functional groups of amide that adsorb on to the surface of particles. These particles are bridged together by the long polymer chain drawing the particles closer together. This process is called flocculation and is widely used in wastewater treatment.

    This results in better settling, cleaner & clearer water, and typically a reduction in, or total elimination of, polyacrylamide flocculants, which creates cost savings and simpler operation. Lastly, the components of the blend also lead to improved oily waste coagulation when compared to other coagulants.

    When flocculation is in progress the mixing energy is reduced to prevent the mass of particles from separating again. Stage 3. Once floc is beginning to form, a polymer chemical is added to the wastewater. Polymers bridge the flocculant from micro to macro flocculant, meaning that the mass of particles collecting together gets bigger.
