Isebenza njani iFlocculant kunyango lwamanzi?

Iiflocculantszidlala indima ebalulekileyo ekunyangweni kwamanzi ngokunceda ekususweni kwamasuntswana axhonyiweyo kunye nee-colloids emanzini. Le nkqubo ibandakanya ukwakheka kwee-floc ezinkulu ezinokuzinza okanye zisuswe ngokulula ngokuhluzwa. Nantsi indlela ezisebenza ngayo ii-flocculants ekunyangweni kwamanzi: 

Ii-Flocculants ziikhemikhali ezongezwa emanzini ukuze kube lula ukuhlanganisana kwamasuntswana amancinci, azinzileyo abe ziingceba ezinkulu, ezisuswayo ngokulula ezibizwa ngokuba zii-flocs.

Iindidi eziqhelekileyo ze-flocculants ziquka ii-inorganic coagulants ezifanaI-Polymeric Aluminium Chloride(I-PACkunye ne-ferric chloride, kunye nee-organic polymeric flocculants ezinokuba zii-polymers zokwenziwa ezifana ne-polyacrylamide okanye izinto zendalo ezifana ne-chitosan.

Ukujiya:

Ngaphambi kokuba i-flocculation iqhume, i-coagulant ingongezwa ukuze iphazamise ukuzinza kwamasuntswana e-colloidal. Ama-coagulant anciphisa iindleko zombane kumasuntswana, nto leyo evumela ukuba ahlangane.

Izinto ezisetyenziswa rhoqo ziquka i-polymeric aluminium chloride, i-aluminium sulfate (alum) kunye ne-ferric chloride.

Ukuqunjelwa kwesikhumba:

Ii-Flocculants zongezwa emva kokujiya ukuze kukhuthazwe ukwakheka kwee-floc ezinkulu.

Ezi khemikhali ziyasebenzisana namasuntswana angasebenzi kakuhle, nto leyo ebangela ukuba ahlangane aze ngokukhawuleza enze ii-aggregates ezinkulu nezibonakalayo.

Ukwakheka kweFloc:

Inkqubo yokuqunjelwa iphumela ekudalweni kwee-flocs ezinkulu nezinzima ezihlala ngokukhawuleza ngenxa yokwanda kobunzima.

Ukwakheka kwefloc kunceda ekubambeni ukungcola, kuquka izinto eziqinileyo ezixhonyiweyo, iibhaktheriya, kunye nezinye izinto ezingcolisayo.

Ukulungiswa kunye nokucaciswa:

Xa ii-flocs sele zimile, amanzi ayavunyelwa ukuba ahlale kwisitya sokutyibiliza.

Ngexesha lokuhlala, ii-flocs zihlala ezantsi, zishiya amanzi acwengileyo ngaphezulu.

Ukuhluza:

Ukuze kucocwe ngakumbi, amanzi acociweyo anokuhluzwa ukuze kususwe naziphi na iinxalenye ezincinci eziseleyo ezingakahlali.

Ukubulala iintsholongwane:

Emva kokucocwa, ukuhlaliswa, kunye nokuhluzwa, amanzi adla ngokunyangwa ngezibulali-ntsholongwane ezifana nekhlorine ukuze kususwe iintsholongwane eziseleyo kwaye kuqinisekiswe ukhuseleko lwamanzi.

Ngamafutshane, ii-flocculants zisebenza ngokunciphisa i-charge yee-particles ezixhonyiweyo, zikhuthaza ukuhlanganiswa kwee-particles ezincinci, zidala ii-floc ezinkulu ezihlala okanye ezinokususwa ngokulula, nto leyo ekhokelela kumanzi acacileyo nacocekileyo.
