PAM Flocculant: ngwaahịa kemịkalụ siri ike maka ọgwụgwọ mmiri ụlọ ọrụ

Polyacrylamide(PAM) bụ polymer synthetic hydrophilic nke a na-ejikarị na usoro ọgwụgwọ mmiri. A na-ejikarị ya eme ihe dị ka flocculant na coagulant, ihe na-emepụta kemịkalụ na-eme ka ụmụ irighiri ihe kwụsịtụrụ na mmiri na-agbakọta n'ime nnukwu flocs, si otú ahụ na-enyere aka iwepụ ha site na nkọwa ma ọ bụ nzacha. Dabere n'ịdị mma nke mmiri mkpofu, jiri cationic, anionic, ma ọ bụ PAM na-abụghị ionic. Polyacrylamide na-enye ọtụtụ uru na ọgwụgwọ mmiri, gụnyere ịdị irè ya n'ọtụtụ pH, okpomọkụ, na turbidity ranges. Enwere ike nwalee mmetụta coagulation site na iji ule Jar ma ọ bụ nha turbidity.
