wastewater treatment polyacrylamide of polymer flocculant
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.

Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or
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
Cationic Polyacrylamide-wastewater treatment chemical
Cationic polyacrylamide (CPAM for short) is a linear polymer composed of cationic monomer and acrylamide. Agent has functions of flocculation, decolorization, adsorption, turbidity removal, adhesion, etc. It can be used as a sludge dewatering agent and papermaking aid.
cationic flocculant(polyacrylamide) used for municipal
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.
Anionic Polyacrylamide Chemicals Flocculant Water
Anionic Polyacrylamide Chemicals Flocculant Water Treatment Polymer. 1. Product characteristics. Anionic polyacrylamide (APAM) series products are water-soluble linear polymers synthesized under high degree polymerization, easily soluble in water, almost insoluble in the benzene, the ether, the aliphatics, the acetone and other common organic solvents. . At the meantime, APAM series products

Synthetic polymers are highly effective flocculants at small dosages and have high tailorability but poor shear stability. Concern for environmental and ecological issues warrants the use of
Polyacrylamide, Polymer And Polyelectrolyte Flocculant
Polyacrylamide is used to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being sub-categorised as a solution and a white emulsion polymer.

Water Soluble Polymer Flocculants: Synthesis
For instance, environmentally friendly chitosan or cellulose are popular flocculants for wastewater treatment (Section 3.2 gives a survey of recent advances in the use of bio/natural flocculants). However, these polymers are only effective in a small range of pH due to their limited solubility in water.
