Isebenza kanjani i-Poly Aluminium Chloride?

Ezweni lokwelashwa kwamanzi,I-Poly Aluminium Chloride(PAC) isivele njenge-coagulant eguquguqukayo nephumelelayo. Ngokusetshenziswa kwayo kabanzi ekuhlanzeni amanzi okuphuza kanye nezitshalo zokuhlanza amanzi angcolile, i-PAC yenza amaza ngenxa yekhono layo elimangalisayo lokucacisa amanzi nokususa ukungcola. Kulesi sihloko, sihlola ukusebenza kwe-PAC kanye nokubaluleka kwayo emkhakheni wokwelashwa kwamanzi.

I-Chemistry Engemuva kwe-PAC:

I-Poly Aluminium Chloride iyinhlanganisela yamakhemikhali eyakhiwe yi-aluminium ne-chlorine, enefomula i-AlnCl(3n-m)(OH)m. Uhlobo lwayo oluguquguqukayo luvela eqinisweni lokuthi ingaba khona ngezindlela ezahlukene kuye ngokuthi isilinganiso se-aluminium-to-chloride kanye nezinga le-polymerization. Lokhu kuhlukahluka kuvumela i-PAC ukuthi ivumelane nezinselele eziningi zokwelashwa kwamanzi.

Ukuqina kanye nokugoba:

Umsebenzi oyinhloko we-PAC ekuphatheni amanzi ukujiya kanye nokugoqana. Uma i-PAC ingezwa emanzini angavuthiwe, idlula ku-hydrolysis. Phakathi nale nqubo, yakha ama-floc e-aluminium hydroxide, asebenza kahle kakhulu ekubambeni ukungcola okulenga emanzini. Ama-floc e-aluminium hydroxide asebenza njengama-magnet amancane, edonsa futhi ebopha ndawonye izinhlayiya ezifana nokungcola, amabhaktheriya, nezinto eziphilayo.

Ukususwa Kokungcola:

Indlela ye-PAC yokuhlanganisa nokuhlanganisa amanzi isiza ekususeni ukungcola okuhlukahlukene emanzini, okuhlanganisa izinto eziqinile ezilengayo, ama-colloid, ngisho nezinye izinto ezincibilikisiwe. Njengoba ama-floc ekhula futhi esinda, ahlala phansi ethangini lokwelapha ngokusebenzisa i-sedimentation noma abanjwa kalula yizihlungi. Lokhu kuphumela ekukhiqizweni kwamanzi acwebile nahlanzekile.

Ukungathathi hlangothi kwe-pH:

Enye yezinzuzo eziphawulekayo ze-PAC ukungathathi hlangothi kwayo kwe-pH. Ngokungafani nama-coagulant endabuko njenge-aluminium sulfate noma i-ferric chloride, angashintsha kakhulu i-pH yamanzi, i-PAC igcina amazinga e-pH ezinzile. Lokhu kunciphisa isidingo samakhemikhali engeziwe ukulungisa i-pH, okwenza inqubo yokwelapha ibe lula futhi kuncishiswe izindleko.

Izinzuzo Zokusebenzisa i-PAC:

Ukusebenza Kahle: I-PAC isebenza ngempumelelo kuzo zonke izinhlobo zamanzi kanye nokungcola.

Ukuguquguquka: Ingasetshenziswa kokubili ekuhlanzweni kwamanzi okuqala kanye nokwesithathu.

Izinsalela Eziphansi: I-PAC ikhiqiza imikhiqizo embalwa yodaka, okunciphisa izindleko zokulahla.

Izindleko Ezingabizi: Ukusebenza kwayo kahle kanye nokungathathi hlangothi kwe-pH kwenza kube ukukhetha okungabizi kakhulu kwezitshalo zokuhlanza amanzi.

Ukuphepha: I-PAC ngokuvamile ibhekwa njengephephile ukuyiphatha kunezinye izinto ezihlanganisa ama-coagulant.

Izicelo ze-PAC:

I-PAC ithola ukusetshenziswa okukhulu ezimbonini ezahlukahlukene, okuhlanganisa ukwelashwa kwamanzi kamasipala, ukwelashwa kwamanzi angcolile ezimbonini, ngisho nasezimbonini zephepha nezendwangu. Ikhono layo lokususa ukungcola okuhlukahlukene lenza kube ithuluzi elibalulekile lokuqinisekisa ukutholakala kwamanzi ahlanzekile naphephile.

Ekuphetheni, i-Poly Aluminium Chloride (PAC) iyisisombululo esimangalisayo sokwelapha amanzi esisebenza ngokujiya kanye nokugoqana. Ukusebenza kwayo kahle, ukuguquguquka kwayo, kanye nokungathathi hlangothi kwe-pH kuyibeke njengokukhetha okuthandwayo kwezindawo zokwelashwa kwamanzi emhlabeni jikelele. Njengoba isidingo samanzi ahlanzekile siqhubeka nokukhula, i-PAC isalokhu ingumdlali obalulekile ekuqinisekiseni ukufinyelela kwamanzi aphephile naphuzwayo emiphakathini emhlabeni jikelele.
