I-Industrial Wastewater Treatment – ​​Flocculants (PAM)

Emanzini angcolile ezimbonini, ngezinye izikhathi kuba nokungcola okwenza amanzi aguquguquke, okwenza lawa manzi angcolile abe nzima ukuwahlanza.Kuyadingeka ukusebenzisa i-flocculant ukwenza amanzi acace ukuze ahlangabezane nezinga lokukhipha.Kule flocculant, sincomai-polyacrylamide (PAM).

I-Flocculantyokuhlanza amanzi angcolile ezimbonini

I-Polyacrylamide iyi-polymer encibilika emanzini.Iketango layo lamangqamuzana liqukethe amaqembu asezindaweni ezishisayo, angakha izinhlayiya ezilengiswe esixazululweni futhi ahlanganise izinhlayiya ukuze zakhe ama-flocs amakhulu.Ama-flocs amakhulu akhiwe angasheshisa ukuna kwezinhlayiya ezimisiwe futhi asheshise umphumela wokucaciswa kwesixazululo.Uma kuqhathaniswa nokwelashwa okujwayelekile kwamanzi angcolile, ukwelashwa kwamanzi angcolile ngamakhemikhali kuyinkimbinkimbi kakhulu.Enqubweni yokwelapha amanzi angcolile amakhemikhali, ama-ejenti ahlukahlukene afana nama-flocculants, ama-coagulants, nama-decolorizers ayadingeka.Phakathi kwazo, i-flocculant evame ukusetshenziswa yi-nonionic polyacrylamide.

Umkhuba ukuthuthukiswa polyacrylamide

1. Iketango lamangqamuzana e-polyacrylamide liqukethe amaqembu amhlophe, angamunca izinhlayiya ezilengiswe emanzini kanye nebhuloho phakathi kwezinhlayiya ukuze zakhe ama-flocs amakhulu.

2. I-polyacrylamide engeyona i-ionic ingasheshisa ukuna kwezinhlayiya ezimisiwe ngokwakha ama-flocs amakhulu, ngaleyo ndlela isheshise ukucaciswa kwesixazululo futhi ikhuthaze umphumela wokuhlunga.

3. Phakathi kwayo yonke imikhiqizo ye-flocculant, i-polyacrylamide engeyona i-ionic inomphumela omuhle ekwelapheni amanzi angcolile ane-asidi, futhi amanzi angcolile amakhemikhali ngokuvamile ane-acidic.Ngakho-ke, i-polyacrylamide engeyona ionic inezinzuzo zayo eziyingqayizivele kuukwelashwa kwamanzi angcolile ngamakhemikhali.

4. I-coagulant ingasetshenziswa ngokuhambisana nosawoti we-inorganic njenge-polyaluminium, i-polyiron namanye ama-flocculants we-inorganic, futhi umphumela ungcono.Kungenxa yokuthi izici ze-polyacrylamide engeyona ionic ukuthi inezinzuzo ezisobala ekwelapheni amanzi angcolile amakhemikhali.

Sinikezela nge-PAM yekhwalithi ephezulu ngokuhlinzekwa kwefekthri ngesandla sokuqala, ukuze uthole i-PAM engabizi kakhulu kanye nolwazi olugculisayo lwangemva kokuthengisa.
