I-Flocculant isebenza kanjani ekwelashweni kwamanzi?

Ama-Flocculatantsdlala indima ebalulekile ekwelashweni kwamanzi ngokusiza ekususweni kwezinhlayiya ezimisiwe nama-colloids avela emanzini. Le nqubo ifaka ukwakheka kwama-flocs amakhulu angahlala noma asuswe kalula ngokuhlunga. Nakhu ukuthi ama-flocculant asebenza kanjani ekwelashweni kwamanzi: 

Ama-Flocculants angamakhemikhali angezelwe emanzini ukwenza lula ukuhlanganiswa kwezinhlayiya ezincane, eziphethwe ezindaweni ezikhudlwana, eziningi ezisuswa kalula ezibizwa nge-FLOCs.

Izinhlobo ezijwayelekile ze-flocculants zifaka ama-inorganic afanaI-Polymeric aluminium Chloride(Isinyathelo) ne-Ferric Chloride, kanye ne-organic polymeric flocculants engaba yi-polymers zokwenziwa njenge-polyrrylamide noma izinto zemvelo ezinjenge-chitosan.

Ukuhlangana:

Ngaphambi kokuqunjelwa, kungangezwa imali ekhokhwayo kuyo izinhlayiya ze-colloidal. Ama-coalizents athathi hlangothi amacala kagesi ezinhlayiya, zibavumela ukuba zihlangane.

Ama-coagulants ajwayelekile afaka i-polymetic aluminium chloride, i-aluminium sulfate (alum) ne-Ferric chloride.

I-Flocculation:

Ama-Flocculatant angezwa ngemuva kokugxuma ukukhuthaza ukwakheka kwama-flocs amakhulu.

Lawa makhemikhali axhumana nezinhlayiya ezasezakhiweni, ebangela ukuba bahlangane futhi bakhe masinyane, ahlanganise ama-aggregate.

Ukwakheka kweFloc:

Inqubo ye-Floccution iphumela ekwakhiweni kwama-flocs amakhulu futhi asindayo axazulule ngokushesha okukhulu ngenxa yokwanda kwesisindo.

Ukwakheka kwe-Floc kubuye kusiza ekufakweni kokungcola, kubandakanya nama-solids amisiwe, amagciwane nezinye izinto ezingcolile.

Ukuxazulula nokucaciswa:

Lapho ama-flocs esewakhe, amanzi avunyelwe ukuhlala e-basin yedimentation.

Ngesikhathi sokuxazulula, ama-flocs ahlala ezansi, ashiye amanzi acacisiwe ngenhla.

I-FILTRATION:

Ngokuhlanzwa okwengeziwe, amanzi acacisiwe angahle atholwe ekuhlunga ukuze asuse noma yiziphi izinhlayiya ezinhle ezingakaze zixazululwe.

I-Disinfection:

Ngemuva kokugcwala, ukuxazulula, kanye nokuhlunga, amanzi avame ukuphathwa ngokubulala amagciwane anjenge-chlorine ukuqeda ama-microorganisms asele futhi aqinisekise ukuphepha kwamanzi.

Ngamafuphi, ama-flocculatants asebenza ngokungathathi hlangothi kwezinhlayiya ezimisiwe, ukukhuthaza ukuhlanganiswa kwezinhlayiya ezincane, ukudala ama-flocs amakhulu ahlale noma akhishwe kalula, kuholele emanzini acwengekileyo.
