Polyacrylamide in jar


Polyacrylamide is a polymer formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked.


Polyacrylamide is used to flocculate solids in a liquid. This process applies to water treatment and processes like papermaking and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid from being sub-categorised as a solution and a white emulsion polymer.

polyacrylamide formula


The anionic form of linear, water-soluble polyacrylamide is frequently used as a soil conditioner on farmland and construction sites for erosion control, in order to protect the water quality of nearby rivers and streams.

The ionic form of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminium chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate. This allows water treatment plants to greatly improve the removal of Total Organic Content (TOC) from raw water.

Removal of Suspended Solids and COD
You coagulate and flocculate effluent to remove the suspended solids from wastewater at the end of a manufacturing process. The coagulant changes the electrical charge of the suspended solids so they start to attract each other to form small particles. Flocculation brings these small particles together to form flocs, using mechanical processes (eg DAF) these flocs can be made to either rise or fall to allow them to be removed from the wastewater. Once these suspended solids and the COD values associated with them are removed, the clean effluent can then be let to sewer, potentially saving your company thousands of pounds annually in trade effluent charges.
