What is polyacrylamide used for?

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 anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.

Does cross-linked polyacrylamide coagulant work better?

Turbidity measurement and the Jar test were used to determine the efficiency of the coagulant. The results showed that cross-linked polyacrylamide worked better than a linear one in coagulating solids particles present in wastewater with improved slurry solids separation efficiency.

What are the uses of acrylamide polymeric materials?

Acrylamide polymeric materials were used in the treatment of waste water for the removal of metallic ions from their corresponding metal salt solution. They were also used for the separation of radioactive isotopes from radioactive liquid waste.

Are hydrogels a smart material for wastewater treatment?

Hydrogels are being investigated recently for wastewater treatment. These polymeric networks permit their functional group alterations imparting high binding affinity for different contaminants in wastewater. Their innate ability to imbibe huge volume of water qualifies it for a smart material for water remediation.

What is dewatered polyacrylamide emulsion?

.Dewatered emulsionsDewatered polyacrylamide emulsions differs from standard by the fact that they contain less than 6% water, with the result that the hydrogel has become almost the dry polymer itself. The consistency of the polymer is simi ar to plastic material. Most dewatered polyacrylamide emulsions from SNF ha

Can a polyacrylamide emulsion be diluted with water?

r solutionFundamentalsPolyacrylamide emulsions are not simple concentrated solutions of polymer, so a simple dilution i water is not possible. When preparing a polymer solution from an emulsion, there are two physical phenomena (phase inversion and dissolution) which take place and need specific conditi
