polyacrylamide chemicals polyacrylamide sciencedirect topics,polyacrylamide gels have the great advantage of being almost completely homogeneous, and adsorption and electro-osmosis do not play a major role in the electrophoresis (see e.g. maurer, 1971). electrophoresis on polyacrylamide gels, as in all other methods of electrophoresis, can be either ‘continuous’ ( raymond and weintraub, 1959 ) or
- Which flocculant is best for pulp paper mill wastewater treatment?
- 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.
- Which polyacrylamide has the highest flocculation efficiency?
- Among the nine polyacrylamides studied, Organopol 5415 (C-PAM) with high molecular weight and low charge density gives the highest flocculation efficiency, with 95% turbidity reduction, 98% TSS removal, and 93% COD reduction, at the optimum dosage of 5 mg l -1 ( Wong et al. 2006 ).
- How effective is coagulation flocculation in pulp paper mill wastewater treatment?
- The coagulation–flocculation process is effective in treating pulp and paper mill wastewater with respect to turbidity reduction, TSS removal, COD reduction, and water recovery. When coagulant is used alone, the optimal dosages for alum and PACl are 1000 mg l -1 and 500 mg l -1, respectively. The optimal pH is 6.0 for both coagulants.
- What is polyacrylamide (PAM) used for?
- High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
