Ọgwụgwọ Mmiri Mkpofu Ụlọ Ọrụ - Flocculants (PAM)

N'ime mmiri mkpofu ụlọ ọrụ mmepụta ihe, mgbe ụfọdụ, e nwere ihe ndị na-adịghị ọcha nke na-eme ka mmiri ahụ dị ka ígwé ojii, nke na-eme ka mmiri mkpofu ndị a sie ike ihicha. Ọ dị mkpa iji flocculant mee ka mmiri ahụ doo anya ka ọ wee ruo n'ọkwa mwepụta. Maka flocculant a, anyị na-akwado ya.polyacrylamide (PAM).

Flocculantmaka ọgwụgwọ mmiri mkpofu ụlọ ọrụ mmepụta ihe

Polyacrylamide bụ polima mmiri na-agbaze. Agbụ ígwè molekul ya nwere otu polar, nke nwere ike ịmịnye mkpụrụ ndụ ndị a kwụnyere n'ime mmiri ahụ ma jikọta mkpụrụ ndụ ndị ahụ iji mepụta flocs buru ibu. Flocs buru ibu ndị e mepụtara nwere ike ime ka mmiri ozuzo nke mkpụrụ ndụ ndị a kwụnyere ngwa ngwa ma mee ka mmetụta nke ngwọta dịkwuo ngwa ngwa. Ma e jiri ya tụnyere ọgwụgwọ mmiri mkpofu nkịtị, ọgwụgwọ mmiri mkpofu kemịkalụ dị mgbagwoju anya. N'ime usoro ọgwụgwọ mmiri mkpofu kemịkalụ, a chọrọ ihe dị iche iche dịka flocculants, coagulants, na decolorizers. N'ime ha, flocculant a na-ejikarị eme ihe bụ nonionic polyacrylamide.

Usoro mmepe nke polyacrylamide

1. Agbụ ígwè polyacrylamide nwere otu polar, nke nwere ike ịmịkọrọ ihe ndị a kwụnyere n'ime mmiri ma jikọta ha n'etiti ihe ndị ahụ iji mepụta flocs buru ibu.

2. Polyacrylamide na-abụghị ionic nwere ike ime ka mmiri ozuzo nke ihe ndị a kwụsiri ike dịkwuo ngwa ngwa site n'ịmepụta flocs buru ibu, si otú a mee ka nkọwa nke ngwọta ahụ dịkwuo ngwa ngwa ma kwalite mmetụta nzacha ahụ.

3. N'ime ngwaahịa niile na-emepụta ihe na-adịghị na ionic, polyacrylamide na-abụghị ionic nwere ezigbo mmetụta n'ịgwọ mmiri mkpofu acidic, mmiri mkpofu kemịkalụ na-abụkarịkwa acidic. Ya mere, polyacrylamide na-abụghị ionic nwere uru pụrụ iche ya naọgwụgwọ mmiri mkpofu kemịkalụ.

4. Enwere ike iji coagulant ahụ jikọta ya na nnu ndị na-adịghị na organic dịka polyaluminum, polyiron na ihe ndị ọzọ na-adịghị na organic flocculants, mmetụta ya ka mma. Ọ bụ kpọmkwem n'ihi njirimara nke polyacrylamide na-abụghị ionic ka o ji nwee uru doro anya n'ịgwọ mmiri mkpofu kemịkalụ.

Anyị na-enye PAM dị elu maka nnyefe ngwa ngwa nke ụlọ ọrụ mmepụta ihe ahụ, ka i wee nwee ike nweta PAM dị ọnụ ala ma nweta ahụmịhe dị mma mgbe erechara ya.
