Iji wepụta ma ọ bụ megharịa mmiri mmiri ahụ ka emechara ọgwụgwọ, ọ dị mkpa iji kemịkal dị iche iche mee ihe na usoro ọgwụgwọ nsị.Taa,Ndị na-eweta PAM (Polyacrylamide).ga-agwa gị gbasara flocculants:

Flocculant: Mgbe ụfọdụ, a na-akpọkwa coagulant, enwere ike iji ya dị ka ụzọ isi mee ka ikewapụ mmiri siri ike sie ike, a pụkwara iji ya na tankị edozi isi, tankị na-edozi nke abụọ, tankị flotation, ọgwụgwọ tertiary ma ọ bụ ọgwụgwọ dị elu na njikọ usoro ndị ọzọ.

A na-eji flocculants mee ihe dị ka ụzọ isi mee ka ikewapụ mmiri siri ike sie ike n'ọhịa nke ọgwụgwọ nsị.Enwere ike iji ha mee ihe iji wusie ike isi sedimentation nke nsị mmiri, ọgwụgwọ flotation na sedimentation nke abụọ mgbe usoro sludge rụọ ọrụ, a pụkwara iji ya mee ihe maka ọgwụgwọ ụlọ akwụkwọ sekọndrị ma ọ bụ ọgwụgwọ dị elu nke nsị.Mgbe ejiri ya mee ihe maka ntụ oyi tupu akpọnwụ nke oke sludge, flocculants na coagulant na-aghọ ntụ oyi sludge ma ọ bụ ihe na-ekpochapụ mmiri.

Mgbe ị na-eji flocculants ọdịnala, enwere ike iji usoro ịgbakwunye ihe enyemaka coagulant iji kwalite mmetụta flocculation.Dịka ọmụmaatụ, iji silicic acid na-arụ ọrụ dị ka ihe enyemaka coagulant maka flocculants inorganic dị ka ferrous sulfate na aluminum sulfate na ịgbakwunye ha n'usoro nwere ike nweta ezigbo flocculat.Ya mere, n'okwu ndị nkịtị, a na-akwado IPF inorganic polymer flocculant site na ijikọta enyemaka coagulant na flocculant wee tinye ọnụ iji mee ka ọrụ onye ọrụ dị mfe.
