Polyacrylamide The Amount Is Also Large
Oct 23, 2017

Sludge is the inevitable outcome of urban sewage treatment, Polyacrylamide first of all we should understand the source of sludge, nature, composition and solid content. According to the sludge contains the main components of different sludge can be divided into organic sludge and inorganic sludge. In general, cationic polyacrylamide for the treatment of organic sludge, anionic polyacrylamide for inorganic sludge, Polyacrylamide alkaline is not strong when the cationic polyacrylamide should not be used, and acidity should not be used when the anionic polyacrylamide, solid content When the sludge is usually high, the amount of polyacrylamide is also large.

The size of the floc: floc too small will affect the speed of drainage, floc too will make the flocs to bind more water and reduce the mud cake dryness. The size of the floc can be adjusted by selecting the molecular weight of the polyacrylamide.

Polyacrylamide ion degree: for the dewatered sludge, Polyacrylamide can be used to different degrees of flocculant by doing a small test for screening, select the best suitable polyacrylamide, so that you can get the best flocculant effect, but also So that the least amount of drugs, cost savings.

Floc strength: flocs in the shear under the action should remain stable without breaking. Polyacrylamide Increasing the molecular weight of polyacrylamide or selecting the appropriate molecular structure can improve the stability of floc.

Polyacrylamide mixed with the sludge: Polyacrylamide in the dehydration of a certain location must be fully reacted with the sludge, the role. To this end, the viscosity of polyacrylamide solution must be appropriate, in the existing equipment conditions can be fully mixed with the sludge, Polyacrylamide the two mixed even if it is a key factor in success. The viscosity of polyacrylamide solution is related to its molecular weight and formulation concentration.

Polyacrylamide dissolved: dissolved in order to play a full play flocculation. Sometimes need to speed up the dissolution rate, then consider increasing the concentration of polyacrylamide solution.

Cationic polyacrylamide (CPAM) sludge dehydration dedicated series Description: the appearance of white powder or granular, ionic degree from 10% to 80% water solubility, Polyacrylamide and can be dissolved in any proportion of water and insoluble in organic solvents. High polymer electrolyte, suitable for the use of waste water and organic-rich wastewater treatment. At present for the dyeing, paper, food, Polyacrylamide construction, metallurgy, mineral processing, coal, oil, aquatic products processing and fermentation industry organic colloid High content of wastewater treatment, especially for urban sewage, urban sludge, paper sludge and other industrial sludge dewatering treatment.
