Ngwaahịa a gbanwere nke polyacrylamide ejiri mee ihe dị ka njigide na ihe mgbapụta mmiri na-emepụta akwụkwọ na-abụkarị ngwaahịa nke polyacrylamide, gụnyere anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM) na amphoteric polyacrylamide (AmPAM), yana ihe dị ka nde 2 ~ 4 nde. .
N'ozuzu, APAM na-etolite usoro mgbagwoju anya yana ogige cationic ndị ọzọ iji mee mmetụta nkwado njide siri ike.Dịka ọmụmaatụ, ijikọ na aluminom sulfate nwere ike ime ka APAM nwee njikọ chiri anya na eriri, eriri dị mma, ihe ndochi, wdg, si otú ahụ na-eme ka njide nke eriri na ihe ndị dị mma.Ọnụ ọgụgụ nlebara anya.
