Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
Stormwater Best Management Practice: Polymer Flocculation
covered with polymer flocculant powder to clarify the water before it’s discharged. The turbidity of water coming from the drilling rig was over 5,000 NTU. But after the settling pit and polymer flocculation in the mixing ditch and dispersion field, the discharged water’s turbidity was reduced to 2 NTU.

Acrylamide in Drinking-water
in the production of polyacrylamide. Both acrylamide and polyacrylamide are used mainly in the production of flocculants for the clarification of potable water and in the treatment of municipal and industrial effluents. They are also used as grouting agents in the construction of drinking-water reservoirs and wells (IPCS, 1985).
Properties of PolyacrylamidesPropertiesApplicationsThermo-Physical PropertiesPolyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH2CH(CONH2)-]. It is a non-ionic, watersoluble, and biocompatible polymer that can be tailored to meet a broad range of applications. The polymer can be synthesized as a simple linea...
Flocculant definition of flocculant by The Free Dictionary
The flocculation is a solid-liquid separation process, which consists of adding a flocculant into the raw water, after which finely divided or dispersed particles are aggregated or agglomerated together to form large particles of such a size (flocs) which settle and cause clarification of the system .
