Ukwelashwa kwamanzi wezimboni - I-Flocculants (Pam)

Emanzini angcolile wezimboni, kwesinye isikhathi kukhona ukungcola okwenza amanzi anamafu, okwenza laba basasele babe nzima ukuba bahlanze. Kuyadingeka ukusebenzisa i-flocculant ukwenza amanzi acace ukuze ahlangabezane nezinga lokuphuma. Kulesi flocculant, siyancomapolycrylamide (pam).

I-flecculontantNgokwelashwa kwamanzi wezimboni

I-Polyacrylamide iyi-polymer esolulekayo yamanzi. I-molecula chain yayo iqukethe amaqembu ama-polar, angenza izinhlayiya ze-adsorb ezimiswe kusisombululo futhi agculisa izinhlayiya zokwakha ama-flocs amakhulu. Ama-Flocs amakhulu asungulwe angasheshisa imvula yezinhlayiya ezimisiwe futhi asheshise umphumela wokucaciswa kwesixazululo. Uma kuqhathaniswa nokwelashwa kwamanzi okujwayelekile, ukwelashwa kwamanzi amakhemikhali kuyinkimbinkimbi kakhulu. Esezinhlelweni zokwelapha amanzi angcolile amakhemikhali, abenzeli abahlukahlukene njengama-flocculants, ama-coabulants, kanye nezihlokwana ziyadingeka. Phakathi kwazo, i-flocculant evame ukusetshenziswa yi-polylic ye-polylacrylamide.

Inkambiso yentuthuko ye-polyyamide

1. I-PolyryryRelar Molecular chain iqukethe amaqembu ama-polar, angadonsa izinhlayiya ezimiswe emanzini kanye nebhuloho phakathi kwezinhlayiya zokwakha ama-flocs amakhulu.

2. I-Mon-ionic PolyAcrylamide ingasheshisa imvula yezinhlayiya ezimisiwe ngokwakha ama-flocs amakhulu, ngaleyo ndlela isheshise ukucaciswa kwesisombululo futhi kuthuthukiswe umphumela wokuhlunga.

3. Phakathi kwayo yonke imikhiqizo ye-Flocculant, i-PolyAcrylamide engekho emthethweni inomphumela omuhle ekwelapheni amanzi amdaka acidic, namanzi amdaka amakhemikhali ngokuvamile acidic. Ngakho-ke, i-polylrylamide engeyona eye-ionic inezinzuzo zayo ezihlukile ngaphakathiUkwelashwa kwamanzi amakhemikhali.

I-4. I-coagulant ingasetshenziswa ngokuhambisana nosawoti we-inorganic efana ne-polyaluminum, ama-polyiron nezinye izimbali ezi-inOrganic, futhi umphumela ungcono. Kunengqondo ngenxa yezimfanelo ze-nonic polycacise ezingezona ezikhona ekwelapheni kwamanzi amdaka amakhemikhali.

Sihlinzeka nge-pam esezingeni eliphakeme ngokuhlinzekwa kwefektri yokuqala, ukuze ukwazi ukuthola i-pam esebenza ngezindleko kanye nesipiliyoni esinelisayo ngemuva kokuthengisa.
