What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

Is cationic polyacrylamide a coagulant aid with titanium tetrachloride?

Cationic polyacrylamide as coagulant aid with titanium tetrachloride for low molecule organic matter removal J. Hazard. Mater., 258-259 ( 2013), pp. 84 – 92 Evaluation of cationic polyacrylamide-based hybrid coagulation for the removal of dissolved organic nitrogen Environ. Sci. Pollut Res., 25 ( 15) ( 2018), pp. 14447 – 14459

Which is better cationic or anionic polyacrylamide?

Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.

Can polyacrylamide be used as a coagulant aid?

Reduce the amount of flocculant. Under the premise of achieving the same water quality, the use of polyacrylamide as a coagulant aid in combination with other flocculants can greatly reduce the amount of flocculant used. Improve water quality.
