Cationic Polyacrylamide Flocculant for Pulp and Paper
Cationic Polyacrylamide Flocculant Used in Pulp and Paper Sludge Dewatering Treatment . Description: Blufloc C8030 is high molecular weight cationic polyacrylamide, used for different kinds of sludge dewatering, works in belt filter, screw filter and centrifugar filter.
Cationic polyacrlyamide Organopol 5415 with very high molecular weight and low charge density is found to give the highest flocculation efficiency in the treatment of the paper mill wastewater.
Flocculation of kaolin particles with cationic lignin
Among the cationic polyacrylamides that Ariffin and coworkers 42 studied in the flocculation of palm oil mill effluent, the flocculant with the molecular weight of 1.5 × 10 6 g/mol was the most
Abstract Functional monomer [N-(2,4,4-trimethylpentan-2-yl)acrylamide] was synthesized and characterized by MS and NMR. A series of high molecular weight cationic polyacrylamides were prepared with N-(2,4,4-trimethylpentan-2-yl)acrylamide, acrylamide and methacryloxyethyltrimethyl ammonium chloride by copolymerization using complex initiation systems as catalysts in aqueous solution.
Treatment of pulp and paper mill wastewater
Organopol 5415 with very high molecular weight and low charge density is the best flocculant with highest flocculation efficiency for the treatment of the pulp and paper mill wastewater. It can achieve 95% of turbidity reduction, 98% of TSS removal, 93% of COD reduction and SVI of 14 ml g −1 at the optimum dosage of 5 mg l −1 .
The results show that when the pulp concentration is 30%, the polyacrylamide is cationic and the molecular weight is 10 million, the optimal content of the flocculant is 3‰, the optimum dose of the polyaluminum chloride with a content of 28 is 0.1‰, the optimum dose of polyaluminum sulfate is 1‰, and the optimum dose of polymeric ferric
Synthesis of Cationic Starch Flocculant and Properties
Based on the high turbidity feature of mine water, Glutinous Rice Starch(St)- Acrylamide(AM) graft polymer cationic flocculant was synthesised by copolymerization with St and AM as materials, ammonium persulfate and sodium hydrogen sulfite as the initiator, 2.3-glycigyl trimethyl ammonium chloride were used as cationic agent. The optimum condition of cation was established through orthogonal
The present review article classifies the flocculants that have been studied and applied in wastewater treatment into three categories including chemical coagulants/flocculants, natural bio-flocculants and grafted flocculants as shown in Fig. 1.Chemical coagulants/flocculants are conventionally applied in wastewater treatment and derived from chemically/petroleum-based materials.
An Effective Flocculation Method to the Kaolin Wastewater
P(AM-DMC) (PAD) was synthesized by ultraviolet- (UV-) initiated copolymerization with methacryloxyethyl trimethyl ammonium chloride (DMC) and acrylamide (AM) as the monomers and initiator 2,2-azobis [2-(2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as the photoinitiator. Parameters that affect the molecular weight were reviewed by using the single-factor approach.
