Kutheni i-flocculants kunye ne-coagulants zifunekayo kunyango lwamanzi amdaka?

Iiflocculantskunye neecoagulants zidlala indima ebalulekileyo kwiinkqubo zokucocwa kwelindle, zinegalelo elikhulu ekususweni kwezinto eziqinileyo ezinqunyanyisiweyo, izinto eziphilayo, kunye nezinye izinto ezingcolisa amanzi amdaka. Ukubaluleka kwazo kusekukwazini kwazo ukomeleza ukusebenza kweendlela ezahlukeneyo zonyango, ekugqibeleni kukhokelele kumanzi acocekileyo anokukhutshwa ngokukhuselekileyo kokusingqongileyo okanye aphinde asetyenziswe ngeenjongo ezahlukeneyo.

I-coagulants ivame ukubhekisela kwi-aluminium okanye i-ferric compounds, njenge-aluminium sulfate, i-polyaluminium chloride kunye ne-polyferric sulfate. I-Flocculants ibhekisela kwiipolymers eziphilayo, ezifana ne-polyacrylamide, i-poly(diallyldimethylammonium chloride), njl njl. Zingasetyenziswa ngabanye okanye ngokudibeneyo.

I-Particle Agglomeration: I-Sewage iqulethe uluhlu olwahlukeneyo lwamasuntswana amisiweyo, kubandakanywa izinto eziphilayo, iibhaktheriya, kunye nezinye izinto ezingcolileyo. I-Flocculants kunye ne-coagulants iququzelela ukuhlanganiswa kwezi ngqungquthela zibe zinkulu, i-denser flocs.Iicoagulantssebenza ngokunciphisa imirhumo engalunganga kumasuntswana amisiweyo, ebavumela ukuba bahlangane kwaye benze amaqoqo amakhulu. Kwelinye icala, iiflocculants zikhuthaza ukwakheka kweeflocs ezinkulu ngokudibanisa amasuntswana okanye ngokuzibangela zingqubane zize zincamathele.

UkuHlaliswa okuPhuculweyo: Emva kokuba amasuntswana adityaniswe abe ziiflocs ezinkulu, ahlala ngokulula phantsi kwefuthe lomxhuzulane okanye ezinye iindlela zokwahlula. Le nkqubo, eyaziwa ngokuba yintlenge, linyathelo elibalulekileyo ekucocweni ilindle, njengoko ivumela ukususwa kwezinto eziqinileyo ezimisiweyo kunye nobunye ukungcola kumanzi amdaka. Iiflocculants kunye ne-coagulants ziphucula ukuhlaliswa ngokunyusa ubungakanani kunye nokuxinana kweeflocs, ngaloo ndlela kukhawulezisa inkqubo ye-sedimentation kunye nokuphucula ukucaca kwamanzi acociweyo.

UHlumelo olomeleziweyo: Kwezinye iindawo zokucocwa kwamanzi amdaka, ukucocwa kwelindle kusetyenziswa njengenyathelo lonyango lwenqanaba lesithathu ukususa ngakumbi izinto ezisele zinqunyanyisiwe kunye nokungcola. Iiflocculants kunye ne-coagulants zincedisa ukuhluza ngokuququzelela ukubunjwa kweengqungquthela ezinkulu ekulula ukuzibamba kunye nokususa emanzini. Oku kukhokelela kumanzi amdaka acocekileyo ahlangabezana nemigangatho engqongqo yobulunga kwaye anokukhutshwa ngokukhuselekileyo okanye aphinde asetyenziswe ngeenjongo ezahlukeneyo ezifana nokunkcenkceshela okanye iinkqubo zemizi-mveliso.

Ukuthintelwa kokungcola: Kwiinkqubo zonyango ezifana ne-membrane filtration kunye ne-osmosis eguqukayo, ukuhlambalaza okubangelwa ukuqokelela kwezinto eziqinileyo ezimisiweyo kwiimbumba zokucoca kunokunciphisa kakhulu ukusebenza kwenkqubo kunye nokwandisa iimfuno zokugcinwa. Iiflocculants kunye ne-coagulants zinceda ekukhuseleni ukungcola ngokukhuthaza ukukhutshwa kwezi ngqungquthela ngaphambi kokuba zifike kwinqanaba lokuhluza. Oku kunceda ukwandisa ubomi be-membrane zokuhluza kunye nokugcina ukusebenza konyango okungaguqukiyo ekuhambeni kwexesha.

Iiflocculants kunye ne-coagulants zizinto eziyimfuneko kunyango lwelindle. Ukukwazi kwabo ukukhuthaza i-particle agglomeration, ukuphucula ukuhlaliswa kunye nokucoca, ukunciphisa ukusetyenziswa kweekhemikhali, kunye nokuthintela ukungcola kubenza zibe zixhobo ezibalulekileyo zokuqinisekisa ukusebenza kunye nokuzinza kwemisebenzi yokucocwa kwamanzi amdaka.
