Isebenza kanjani i-Flocculant ekuhlanzeni amanzi?

Ama-Flocculantsidlala indima ebalulekile ekuhlanzeni amanzi ngokusiza ekukhipheni izinhlayiya ezimisiwe nama-colloid emanzini.Inqubo ihilela ukwakheka kwama-flocs amakhulu angahlala noma asuswe kalula ngokuhlunga.Nansi indlela ama-flocculants asebenza ngayo ekuhlanzeni amanzi: 

Ama-flocculants ngamakhemikhali anezelwa emanzini ukuze kube lula ukuhlangana kwezinhlayiya ezincane ezingasebenzi kahle zibe izixuku ezinkulu, ezisuseka kalula ezibizwa ngokuthi ama-flocs.

Izinhlobo ezijwayelekile zama-flocculants zifaka ama-coagulants angaphili njengawoI-Polymeric Aluminium Chloride(I-PAC)kanye ne-ferric chloride, kanye nama-organic polymeric flocculants angaba ama-polymer okwenziwa njenge-polyacrylamide noma izinto zemvelo ezifana ne-chitosan.

I-coagulation:

Ngaphambi kwe-flocculation, i-coagulant ingase yengezwe ukuze iphazamise izinhlayiya ze-colloidal.Ama-coagulant anciphisa amashaji kagesi ezinhlayiyeni, ezivumela ukuthi zihlangane.

Ama-coagulant ajwayelekile afaka i-polymeric aluminium chloride, i-aluminium sulfate (i-alum) ne-ferric chloride.

I-Flocculation:

Ama-flocculants ayengezwa ngemva kokuhlangana ukuze akhuthaze ukwakheka kwama-flocs amakhulu.

Lawa makhemikhali asebenzisana nezinhlayiya ezingasebenzi kahle, azenze zihlangane futhi ngokushesha zakhe amaqoqo amakhulu, abonakalayo.

Ukwakhiwa kwe-Floc:

Inqubo ye-flocculation iphumela ekudaleni ama-flocs amakhulu futhi asindayo ahlala ngokushesha ngenxa yokwanda kwesisindo.

Ukwakheka kwe-Floc kusiza futhi ekubambeni ukungcola, okuhlanganisa okuqinile okumisiwe, amagciwane, nokunye ukungcola.

Ukulungisa nokucacisa:

Uma ama-flocs sewakhiwe, amanzi avunyelwe ukuhlala endaweni yokuthungatha.

Ngesikhathi sokuhlalisa, ama-flocs ahlala phansi, eshiya amanzi acacisiwe ngaphezulu.

Ukuhlunga:

Ukuze uthole ukuhlanzwa okwengeziwe, amanzi acacisiwe angase afakwe ngaphansi kokuhlunga ukuze asuse noma yiziphi izinhlayiya ezisele ezisele ezingakahlali.

Ukubulala amagciwane:

Ngemuva kwe-flocculation, ukulungiswa, nokuhlunga, amanzi avame ukuphathwa ngezibulala-magciwane ezifana ne-chlorine ukuze kuqedwe ama-microorganisms asele futhi kuqinisekiswe ukuphepha kwamanzi.

Ngamafuphi, ama-flocculants asebenza ngokunciphisa ukukhokhiswa kwezinhlayiya ezimisiwe, ukukhuthaza ukuhlanganiswa kwezinhlayiya ezincane, ukudala ama-flocs amakhulu ahlala noma angasuswa kalula, okuholela emanzini acacile nahlanzekile.
