Treatment of tannery wastewater by chemical coagulation
Chemical coagulation-flocculation (CF) is a chemical treatment technique followed by sedimentation to enhance the ability of a treatment process to remove suspended particles.
wastewater treatment. With ever increasing demands from the Environment Agency to minimise pollutants in water effluent arising from industrial processes, Morselt Borne BV can offer a solution which works well in many industries. This is the Red Box Electro Coagulation system whereby contaminants are flocculated by an electrical process

Type of the treatment to be applied for effluent depends upon various factors like physical state of the effluent, degree of hazard of pollutant, chemical complexity of the effluent and so on. The simple way of disposing the waste produced is just to dispose them no nearby water-bodies or to convenient open land.
Chemical industry wastewater treatment
The results obtained revealed that chemical treatment of washing water from the scrubbing towers including recycling heated effluent waste (with a ratio of 1:2) was recommended.

Degradation of Polyacrylamide (PAM) and methane production by mesophilic and thermophilic anaerobic digestion: Effect of temperature
Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD). The
Polyacrylamide referred to as PAM (anionic, cationic, nonionic) Polyacrylamide, abbreviated as PAM, is a water-soluble linear polymer synthesized with high degree of polymerization, which has valuable properties such as flocculation, thickening, shearing, resistance reduction and dispersibility. Soluble in water, almost insoluble in benzene

Cationic polyacrylamide(PAM) for water treatment
Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and can decrease the resistance between liquids.

- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- Is nionic polyacrylamide a hazard?
- nionic polyacrylamide.NICNAS has assessed anionic polyacrylamide in an IMAP Tier 1 assessment and considers it a po ymer of low concern1 . In addition, based on an assessment of environmental hazards, NICNAS also identified anionic polyacrylamide as a chemical of low concern to the envi
