Ukwelashwa Kwamanzi Angcolile Ezimbonini – Ama-Flocculants (PAM)

Emanzini angcolile asezimbonini, ngezinye izikhathi kuba nokungcola okwenza amanzi abe namafu, okwenza la manzi angcolile abe nzima ukuwahlanza. Kuyadingeka ukusebenzisa i-flocculant ukuze amanzi acwebe ukuze kuhlangatshezwane nezinga lokukhishwa. Kulokhu ku-flocculant, sincomai-polyacrylamide (i-PAM).

I-Flocculantukwelashwa kwamanzi amdaka ezimbonini

I-Polyacrylamide iyi-polymer encibilika emanzini. Uchungechunge lwayo lwama-molecule luqukethe amaqembu e-polar, angamunca izinhlayiya ezilenga esixazululweni futhi ahlanganise izinhlayiya ukuze zakhe ama-floc amakhulu. Ama-floc amakhulu akhiwe angasheshisa ukuna kwezinhlayiya ezilengayo futhi asheshise umphumela wokucaciswa kwesisombululo. Uma kuqhathaniswa nokwelashwa kwamanzi amdaka okuvamile, ukwelashwa kwamanzi amdaka ngamakhemikhali kuyinkimbinkimbi kakhulu. Enkambisweni yokwelapha amanzi amdaka amakhemikhali, kudingeka izinto ezahlukahlukene ezifana nama-flocculant, ama-coagulant, kanye nama-decolorizer. Phakathi kwazo, i-flocculant esetshenziswa kakhulu yi-nonionic polyacrylamide.

Umkhuba wokuthuthukiswa kwe-polyacrylamide

1. Uchungechunge lwama-molecule e-polyacrylamide luqukethe amaqembu e-polar, angamunca izinhlayiya ezilenga emanzini futhi axhumane phakathi kwezinhlayiya ukuze akhe ama-floc amakhulu.

2. I-polyacrylamide engeyona i-ionic ingasheshisa ukuna kwezinhlayiya ezilengayo ngokwakha ama-floc amakhulu, ngaleyo ndlela isheshise ukucaciswa kwesisombululo futhi ikhuthaze umphumela wokuhlunga.

3. Phakathi kwayo yonke imikhiqizo ye-flocculant, i-non-ionic polyacrylamide inomphumela omuhle ekwelapheni amanzi amdaka ane-asidi, kanti amanzi amdaka amakhemikhali ngokuvamile ane-asidi. Ngakho-ke, i-non-ionic polyacrylamide inezinzuzo zayo ezihlukile kuukwelashwa kwamanzi amdaka ngamakhemikhali.

4. I-coagulant ingasetshenziswa ngokuhlanganiswa nosawoti wezinto ezingaphili njenge-polyaluminum, i-polyiron kanye nezinye izinto ezingaphili, futhi umphumela uba ngcono. Kungenxa yezici ze-non-ionic polyacrylamide ukuthi inezinzuzo ezisobala ekwelapheni amanzi angcolile amakhemikhali.

Sihlinzeka nge-PAM esezingeni eliphezulu yokutholakala kwefektri mathupha, ukuze uthole i-PAM engabizi kakhulu kanye nesipiliyoni esanelisayo ngemuva kokuthengisa.
