anionic polyacrylamide alleviates cadmium inhibition cost
the uncontrolled discharge of industrial wastewater leads to a significant cadmium (cd) accumulation in waste activated sludge (was), posing a serious threat to the steady operation of the anaerobic digestion (ad) system in wastewater treatment plants (wwtps).
coagulation-flocculation studies of tannery wastewater using cationic polymers as a replacement of metal salts pubmed,studies were conducted to evaluate the efficiency of cationic polymers as a suitable replacement of metal salts for the treatment of a local tannery wastewater. eleven cationic polymers of varying molecular weights (mw) and charge densities (cd) were examined using jar test apparatus. three cationic .

how to optimize polymer efficiency for better sludge dewatering,two-stage mixing: very high-energy mixing at initial wetting stage is critical to prevent fisheye formation, followed by low-energy mixing to minimize damaging polymer chain. sufficient residence time of low-energy mixing stage is required to achieve fully dissolved homogeneous solution.
water soluble polymer flocculants synthesis
anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
