I-Polyaluminium chloride ikususa kanjani ukungcola emanzini?

I-Polyaluminium chloride, evame ukufushaniswa njenge-PAC, iwuhlobo lwe-inorganic polymer coagulant. Ibonakala ngokuminyana kwayo okuphezulu kwe-charge kanye nesakhiwo se-polymeric, okuyenza isebenze kahle kakhulu ekuhlanganiseni nasekuntanteni ukungcola emanzini. Ngokungafani nama-coagulant endabuko afana ne-alum, i-PAC isebenza ngempumelelo kulo lonke uhla lwe-pH olubanzi futhi ikhiqiza imikhiqizo embalwa ye-sludge, iyenze ibe enye indlela evumelana nemvelo.

Indlela Yokwenza

Umsebenzi oyinhloko we-PAC ekuhlanzeni amanzi uwukuthunaza nokuhlanganisa izinhlayiya ezinhle ezimisiwe, ama-colloid, nezinto eziphilayo. Le nqubo, eyaziwa ngokuthi i-coagulation kanye ne-flocculation, ingahlukaniswa ngezigaba eziningana:

1. Ukuhlangana: Uma i-PAC yengezwa emanzini, ama-ion ayo e-polyaluminium ashajwe kakhulu anciphisa izindleko ezingezinhle ebusweni bezinhlayiya ezimisiwe. Lokhu kungathathi hlangothi kunciphisa amandla anyanyekayo phakathi kwezinhlayiya, okubavumela ukuba basondelane ndawonye.

2. I-Flocculation: Ngemva kokuhlangana, izinhlayiya ezingathathi hlangothi ziyahlangana ukuze zenze ama-flocs amakhulu. Imvelo ye-polymeric ye-PAC isiza ekuvaleni izinhlayiya, idale ama-flocs amakhulu angasuswa kalula.

3. I-Sedimentation and Filtration: Izinhlamvana ezinkulu ezakheka ngesikhathi sokuhlubuka zizinza ngokushesha ngenxa yamandla adonsela phansi. Le nqubo ye-sedimentation isusa ngokuphumelelayo ingxenye ebalulekile yezinto ezingcolile. Ama-flocs asele angasuswa ngokuhlunga, okuholela emanzini acacile nahlanzekile.

Izinzuzo ze-PAC

I-PACinikeza izinzuzo ezimbalwa ngaphezu kwama-coagulants endabuko, okunomthelela ekudumeni kwawo okukhulayo ekuhlanzeni amanzi:

- Ukusebenza kahle: I-PAC iphumelela kakhulu ekususeni ukungcola okuhlukahlukene, okuhlanganisa okuqinile okumisiwe, izinto eziphilayo, kanye nezinsimbi ezithile ezisindayo. Ukusebenza kahle kwayo kunciphisa isidingo samakhemikhali engeziwe nezinqubo.

- Ububanzi be-pH ebanzi: Ngokungafani namanye ama-coagulant adinga ukulawulwa kwe-pH okunembayo, i-PAC isebenza kahle kububanzi be-pH ebanzi, yenza inqubo yokwelapha ibe lula.

- Ukukhiqizwa Kwedaka Elincishisiwe: Enye yezinzuzo ezibalulekile ze-PAC umthamo oncishisiwe wodaka olukhiqizwa phakathi nokwelashwa. Lokhu kuncipha kwehlisa izindleko zokulahla futhi kunciphisa umthelela wemvelo.

- Ukusebenza Kwezindleko: Nakuba i-PAC ingase ibe nezindleko eziphezulu zangaphambili uma kuqhathaniswa namanye ama-coagulant avamile, ukusebenza kwayo okuphezulu kanye nezimfuneko zemithamo ephansi kuvame ukuphumela ekongeni okupheleleyo kwezindleko zezindawo zokuhlanza amanzi.

I-PAC Flocculants imele intuthuko enkulu kubuchwepheshe bokuhlanza amanzi. Ikhono layo lokususa kahle ukungcola, okuhambisana nezinzuzo zemvelo nezomnotho, libeka i-PAC njengetshe lesisekelo ekufuneni amanzi ahlanzekile naphephile. Njengoba imiphakathi eminingi nezimboni zamukela lesi sixazululo esisha, indlela eya ekusasa elinempilo nelisimeme iba sobala.
