Usoro nke Flocculant - Polyacrylamide

In Ọgwụgwọ Mmiri Mkpofu Ụlọ Ọrụ, a ga-enwe ọtụtụ obere ihe ndị a kpọchiri akpọchi n'ime mmiri mkpofu. Iji wepụ ihe ndị a ma mee ka mmiri ahụ doo anya ma jiri ya mee ihe ọzọ, ọ dị mkpa iji yaIhe mgbakwunye kemịkalụ mmiri -Flocculants (PAM) ime ka ihe ndị a kwụgidere emechi Ihe ndị na-adịghị ọcha na-agbakọta ghọọ nnukwu molekul ma daa.

Mkpụrụ colloid dị n'ime mmiri dị obere, a na-agba mmiri mmiri ma na-agba ya ọkụ iji mee ka ha kwụsie ike. Mgbe etinyere flocculant ahụ na mmiri ahụ, a na-agba ya mmiri ka ọ bụrụ colloid charged na ion ndị gbara ya gburugburu iji mepụta micelles nwere nhazi oyi akwa abụọ nke eletriki.

A na-eji usoro nke ịkpalite ngwa ngwa mgbe e tinyere ọgwụ iji kwalite ohere na ọnụọgụ nke ihe ndị na-akpata nsụkọta n'etiti ihe ndị na-adịghị ọcha na colloidal dị na mmiri na micelles nke hydrolysis nke flocculant mepụtara.
