Shenyang sludge treatment polyacrylamide manufacturers

Shenyang sludge treatment polyacrylamide manufacturers an urban sewage treatment polyacrylamide analysis: the city sewage sludge is an inevitable product of, first of all we should understand the source of the sludge, the nature, composition and solid content. According to different main ingredients contained in the sludge, the sludge can be divided into organic sludge and inorganic sludge. Generally CPAM for treating organic sludge, APAM for inorganic sludge, should not use CPAM highly alkaline, and should not be used when very acidic APAM, when the sludge with high solid content is usually too large an amount of PAM. Second, the size of the polyacrylamide floc: the floc is too small to affect drainage rate, floc floc bound much more water will decrease mud biscuits. By selecting the molecular weight polyacrylamide PAM can be resized floc. Third, the ion degrees of PAM PAM: for dewatering sludge, flocculants available through different ion degrees do first small test screening, to select the best suitable PAM, so that is the best coagulant effect can be obtained, and allows minimal dosage and cost savings. Fourth, polyacrylamide floc strength: floc under shear should be stable and not broken. PAM molecular weight increase or select the appropriate molecular structure contributes to better floc stability. V. mixed with sludge PAM PAM: PAM must be fully reacted sludge, flocculation occurs at a position of dewatering equipment. To this end, PAM solution viscosity must be suitable, adequately mixed with the sludge in the existing equipment condition, whether the two mix, is a critical success factor. PAM and its molecular weight and viscosity of the solution preparation concentration. Sixth, polyacrylamide PAM dissolved: dissolve well in order to send full flocculation. Sometimes the need to accelerate the rate of dissolution, then consider increasing the concentration of PAM solution.
