I-Flocculant isebenza kanjani ekuphatheni amanzi?

Ama-Flocculantidlala indima ebalulekile ekuphathweni kwamanzi ngokusiza ekususweni kwezinhlayiya ezilengayo kanye nama-colloid emanzini. Le nqubo ihilela ukwakheka kwama-floc amakhulu angahlala noma asuswe kalula ngokuhlunga. Nansi indlela ama-flocculant asebenza ngayo ekuphathweni kwamanzi: 

Ama-flocculant angamakhemikhali anezelwa emanzini ukuze kube lula ukuhlangana kwezinhlayiya ezincane, eziphazamisekile zibe yizinqwaba ezinkulu, ezisuswa kalula ezibizwa ngokuthi ama-floc.

Izinhlobo ezivamile zama-flocculant zifaka phakathi ama-coagulant angaphili njengeI-Polymeric Aluminium Chloride(I-PAC) kanye ne-ferric chloride, kanye nama-flocculant e-polymeric e-organic angaba ama-polymers okwenziwa njenge-polyacrylamide noma izinto zemvelo njenge-chitosan.

Ukujiya:

Ngaphambi kokucwiliswa, i-coagulant ingafakwa ukuze iphazamise izinhlayiya ze-colloidal. Ama-coagulant anciphisa izindleko zikagesi ezinhlayiyeni, azivumele ukuthi zihlangane.

Ama-coagulant avamile ahlanganisa i-polymeric aluminium chloride, i-aluminium sulfate (alum) kanye ne-ferric chloride.

Ukukhukhuleka:

Ama-flocculant ayengezwa ngemva kokujiya ukuze kukhuthazwe ukwakheka kwama-floc amakhulu.

La makhemikhali asebenzisana nezinhlayiya eziphazamisekile, okubangela ukuba zihlangane futhi zakhe ngokushesha ama-aggregate amakhulu, abonakalayo.

Ukwakheka kwe-Floc:

Inqubo yokugoqa iphumela ekudalweni kwama-floc amakhulu futhi asindayo ahlala ngokushesha ngenxa yokwanda kobunzima.

Ukwakheka kwe-floc kusiza nasekubambeni ukungcola, okuhlanganisa izinto eziqinile ezilengayo, amabhaktheriya, nezinye izinto ezingcolisayo.

Ukuxazulula Nokucacisa:

Uma ama-floc esebunjiwe, amanzi ayavunyelwa ukuthi ahlale esitsheni sokuthungwa.

Ngesikhathi sokuhlala phansi, ama-floc ahlala phansi, ashiye amanzi acwebile ngaphezulu.

Ukuhlunga:

Ukuze kuhlanzwe kabanzi, amanzi acwengisiwe angase ahlungwe ukuze kususwe noma yiziphi izinhlayiya ezincane ezisele ezingakahlali.

Ukubulala amagciwane:

Ngemva kokucwiliswa, ukuhlanzwa, kanye nokuhlunga, amanzi avame ukuphathwa ngezibulala-magciwane ezifana ne-chlorine ukuze kuqedwe amagciwane asele futhi kuqinisekiswe ukuphepha kwamanzi.

Ngamafuphi, ama-flocculant asebenza ngokunciphisa ukushaja kwezinhlayiya ezilengayo, akhuthaze ukuhlangana kwezinhlayiya ezincane, adale ama-floc amakhulu ahlala noma angasuswa kalula, okuholela emanzini acacile nahlanzekile.
