In ụlọ ọrụ mmepụta ihe mmiri mkpofu ọgwụgwọ, Mwepụ nke ihe siri ike kwụsịtụrụ bụ isi njikọ. Ọ bụghị naanị na nke a na-enyere aka mee ka mma mmiri dịkwuo mma, ọ na-ebelatakwa ike na-eyi na ngwá ọrụ na nkwụsị. Ka ọ dị ugbu a, ụzọ isi wepụ ihe ndị siri ike kwụsịtụrụ gụnyere sedimentation, filtration, flotation na flocculation. N'ime ha, a na-eji usoro flocculation eme ihe n'ọtụtụ ebe n'ihi arụmọrụ dị elu na akụnụba ya. N'ime usoro a, polymer akpọrọ PolyDADMAC na-arụ ọrụ dị mkpa.
PolyDADMAC, onye aha ya zuru oke bụ Poly diallyl dimethyl ammonium chloride, bụ polymer molikula dị elu. A na-emepụta ya nke ọma site na polymerizing diallyldimethylammonium chloride monomer site na ụgbụ uto polymerization. A na-eme mmeghachi omume polymerization a n'okpuru catalysis nke acid ma ọ bụ nnu, na enwere ike nweta polymer usoro linear. Ọ na-abụkarị mmiri mmiri na-acha odo odo ma ọ bụ na-acha ọcha ruo ntụ ntụ ma ọ bụ granules. Ọ nwere ezigbo solubility ma nwee ike gbasasịa ya na ngwọta mmiri.
PolyDADMACnwere njupụta ụgwọ dị elu ma na-akpakwa àgwà dị ka polymer cationic. Nke a pụtara na ọ nwere ike adsorb na-adịghị mma ebubo kwụsịtụrụ solids na colloidal ahụ na mmiri na-etolite nnukwu flocs, si otú ọbọ irè mwepụ nke kwụsịtụrụ solids. A na-ejikarị PolyDADMAC eme ihe dị ka flocculant na coagulant na a na-ejikwa ya n'ọtụtụ ebe na-edozi mmiri dị iche iche, gụnyere ọgwụgwọ mmiri mkpofu ụlọ ọrụ na ọgwụgwọ nsị nke obodo. Ọ nwere ike ịmalite ngwa ngwa buru ibu na nnukwu flocs n'ime mmiri mkpofu ma wepụ ihe siri ike kwụsịtụrụ, ion metal arọ na mmetọ organic.
Na ọgwụgwọ nke mmiri mkpofu sitere na pulp na igwe igwe akwụkwọ, usoro omume nke PolyDADMAC na-egosipụta nke ọma na akụkụ ndị a:
Nkwụsị ụgwọ ụgwọ: N'ihi na PolyDADMAC nwere njupụta ụgwọ dị elu, ọ nwere ike ịgbasa ngwa ngwa na ihe ndị na-adịghị mma kwụsịtụrụ na colloidal particles, na-eme ka ha kwụsị nkwụsi ike site na nkwụsị ụgwọ, wee gbakọta na-etolite flocs nke nnukwu ihe.
Ihe na-ekpochapụ: Dị ka a na-emepụta floc, ọ ga-adọta ihe ndị a kwụsịrị na mmiri na-ekpo ọkụ na mmiri na-ekpo ọkụ n'ime floc, na-enweta nkewa nke mmiri siri ike site na ime ahụ.
Mmetụta netwọk: polymers dị elu nwere ike ịmepụta usoro netwọkụ siri ike, na-ejide ihe siri ike kwụsịtụrụ na ụmụ irighiri ihe dị n'ime ya dị ka ụgbụ azụ, si otú ahụ nweta nkewa nke ọma.
E jiri ya tụnyere ụzọ ọgwụgwọ mmiri mkpofu ndị ọzọ, iji PolyDADMAC na-agwọ pulp na mmiri mkpofu akwụkwọ nwere uru ndị a:
Njupụta ụgwọ dị elu: Njupụta ụgwọ dị elu nke PolyDADMAC na-enyere ya aka ị nweta nke ọma nke ọma n'ebubo siri ike kwụsịtụrụ na ihe colloidal, na-emeziwanye ọgwụgwọ ọgwụgwọ.
Mgbanwe siri ike: PolyDADMAC nwere mmetụta ọgwụgwọ dị mma na ụdị pulp dị iche iche na mmiri mkpofu akwụkwọ na ngbanwe ogo mmiri adịghị emetụta ya.
Ịrụ ọrụ dị elu na obere oriri: Iji PolyDADMAC dị kaFlocculantna coagulant nwere ike ibelata dose nke kemịkalụ nke ukwuu, ebe ọ na-emeziwanye ọgwụgwọ ọgwụgwọ yana ibelata ụgwọ ọrụ.
Enyi na gburugburu ebe obibi: PolyDADMAC bụ polymer cationic. Ìgwè atụrụ a na-emepụta mgbe ejiri ya adịghị mfe ree ka ọ bụrụ ihe na-emerụ ahụ ma bụrụ enyi na gburugburu ebe obibi.
Na mmechi, PolyDADMAC, dị ka aPolymer Molecular dị elu, nwere uru nke ịrụ ọrụ dị elu, obere oriri, na enyi gburugburu ebe obibi, ma na-arụ ọrụ dị mkpa n'ịgwọ mmiri na-ekpofu mmiri site na pulp na igwe mpempe akwụkwọ. N'oge usoro nke nchedo gburugburu ebe obibi siri ike iguzogide, PolyDADMAC bụ ngwaahịa kemịkalụ na-ewu ewu nke na-ezute njirimara nke ngwaahịa enyi na gburugburu ebe obibi.
