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.
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.
- Polyacrylamides are used to make all of our emulsion and powder grade flocculants.
- They are available in both anionic and cationic grades and come packaged in 25kg bags, 750kg bags, 1000 litre IBC’s and 25 Litre Kegs.
- Also Available is GPC ClearFlo NS100 Which is a ready to use anionic liquid flocculant.
- Very versatile can be used in a wide range of applications
