superior quality polyacrylamide CPAM polymer in Joburg

research on a new cationic polyacrylamide (cpam) with high quality

flocculation is a common method to improve filtration efficiency and purify water quality in water supply plants where the commonly used flocculant is cationic polyacrylamide (cpam) (vandamme et al. 2010; teh et al. 2016). for sludge dewatering, cpam shows superior conditioning performance and obtained more and more attention.

optimizing the conditions of cationic polyacrylamide inverse,cationic polyacrylamide (cpam) emulsifier is widely applied in the wastewater treatment industry, mining industry, paper industry, cosmetic chemistry, etc. however, optimization of input parameters in the synthesis of cpam by using the traditional approach (i.e., changing one factor while leaving the others fixed at a particular set of conditions) would require a long time and a high cost of

cationic polyacrylamide copolymers (pam): environmental half

background cationic polyacrylamide copolymers (pam) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. concern has been expressed since little is known about the degradation of pam in soils. to obtain detailed information on the polymer’s fate in the soil compartment, the degradation of 14c

optimization conditions to obtain cationic polyacrylamide,cpam-3 (dc 71.17%) had an m n of 9,633,400 g/mol, m w of 20,425,000 g/mol, and d 2.1202. the cpam samples synthesized by reverse emulsion copolymerization had molecular weight distributions (d) in the range of 2.1–3.4 [28,29]. this means that the polymer backbone of the cpam was uniform.
