Treatment of pulp and paper mill wastewater
Treatment of pulp and paper mill wastewater by polyacrylamide (PAM) in polymer induced flocculation
Flocculation studies between dual polymers on pulp and paper mill wastewater are reported in this paper. The effects of different molecular weights of polyDADMAC and different dosages of Polyacrylamide (PAM) were studied. The molecular weights of polyDADMAC used were 8.8脳104, 10.5脳104 and 15.7脳104 g/mol. The flocculation performance was analyzed in jar tests with PolyDADMAC and
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 鈭? at the optimum dosage of 5 mg l 鈭? .

Selvam K, Swaminathan K, Myung Hoon Song and Keon-Sang Chae, 2002. Biological treatment of a pulp and paper industry effluent by Fomes lividus and Trametes versicolor.
Unfortunately pulp and paper mill wastewater has a low biodegradability index (BOD 5 /COD), typically less than 0.4, clearly showing that paper effluent cannot be treated effectively through conventional biological methods. Several methods have been considered for the removal of COD pollution and colour from the pulp and paper mill effluents.
Polyacrylamide for paper mill water treatment_GONGYI CITY
Polyacrylamide for paper mill water treatment. Polyacrylamide for paper mill is widely used as resident agent, filter agent, homogenizer and water treatment agent in papermaking field.Its function is to improve the quality of paper, improve the dewatering performance of the slurry, improve the retention rate of fine fibers and fillers, reduce the consumption of raw materials and pollution of
Pulp and paper mill effluent is highly polluting and is a subject of great environmental concern. In the present research we studied the removal of chemical oxygen demand (COD) and colour from paper mill effluent, using the coagulation process. A batch coagulation study was conducted using various coagulants such as aluminium chloride (AlCl3), polyaluminium chloride (PAC) and copper sulphate
Pilot Treatment of OCC-based Paper Mill Wastewater Using
wastewater of an old corrugated containerboard (OCC)-based paper mill for water reuse. For the study, a medium-sized mill was selected; it produces 400 t/day of corrugating medium and liner for packaging and discharges 3,500 to 4,000 m /day of wastewater.Experiments were carried out in a pilot-scale alternating electrochemical reactor followed by

- Are agarose and polyacrylamide gels good for electrophoresis?
- But, agarose gels are good for separating large DNA molecules. And, polyacrylamide gels are good for separating small proteins and DNA fragments. Electrophoresis uses agarose and polyacrylamide-based gels to separate biomolecules (DNA, RNA, and proteins). Both types of gels separate biomolecules based on their size and charge.
- How agarose & polyacrylamide gels help in biomolecular separation?
- Both gels help in biomolecular separation, due to their porous nature. We can separate, identify and purify different biomolecules using agarose and polyacrylamide gels. 1. Origin: Agarose is a natural polymer extracted from several red seaweeds. So, it is a marine-based polysaccharide. But, polyacrylamide is a synthetic polymer.
- Which is better agarose gel or polyacrylamide gel?
- For the separation of large DNA or RNA fragments, agarose gels are preferred due to their simplicity and ability to handle larger molecules. Conversely, for the resolution of proteins or small nucleic acids, polyacrylamide gels offer superior resolving power.
- What is the difference between agarose and polyacrylamide?
- In the case of DNA, polyacrylamide is used for separating fragments of less than about 500 bp. However, under appropriate conditions, fragments of DNA differing is length by a single base pair are easily resolved. In contrast to agarose, polyacrylamide gels are used extensively for separating and characterizing mixtures of proteins.
