Wonke umntu uyazi ukuba inani elikhulu lamanzi lifunekayo ekuqhutyweni kweemveliso zesoya, ngoko ke akunakuphepheka ukuba ukungcola kuya kuveliswa.Ke ngoko, indlela yokuphatha ilindle ibe yingxaki enzima kumashishini okujongana nemveliso yesoya.
Ngexesha lokucutshungulwa kweemveliso zesoya, kuye kuvele umthamo omkhulu wamanzi amdaka endalo, ahlulwe kakhulu abe ngamacandelo amathathu: ukucwina amanzi, amanzi okucoca imveliso, kunye namanzi atyheli aludaka.Ngokubanzi, isixa samanzi amdaka akhutshiweyo sikhulu, sinoxinzelelo oluphezulu lwezinto eziphilayo, ukwakheka okuntsokothileyo, kunye neCOD ephezulu.Ukongeza, ubungakanani bamanzi amdaka avelisiweyo ngexesha lokusetyenzwa kweemveliso zesoya anokwahluka ngokuxhomekeke kubungakanani beshishini.
Ngokweemfuno zabathengi, olu luyilo lwamkela indlela yokudada emoyeni.Inkqubo ye-air flotation isebenzisa amaqamza amancinci njengabathwali ukubambelela kunye nokususa i-oyile ezincinci kunye nezinto eziqinileyo ezinqunyanyisiweyo kumanzi amdaka, ukuphumeza ukucocwa kwangaphambili komgangatho wamanzi, ukudala iimeko ezilungele iiyunithi zokunyanga ze-biochemical ezilandelayo, kunye nokunciphisa umthwalo wonyango wezigaba ezilandelayo ze-biochemical.Izinto ezingcolisa amanzi amdaka zohlulwe zibe yi-organic matter enyityilisiweyo kunye ne-insoluble substances (SS).Phantsi kweemeko ezithile, izinto eziphilayo ezinyityilisiweyo zinokuguqulwa zibe zizinto ezinganyibilikiyo.Enye yeendlela zokunyanga ilindle kukongeza i-coagulants kunye ne-flocculants ukuguqula uninzi lwezinto eziphilayo ezinyityilisiweyo kwizinto ezinganyibilikiyo, kwaye emva koko zisuse zonke okanye uninzi lwezinto ezinganyibilikiyo (SS) ukufezekisa injongo yokucoca ilindle, Eyona nto iphambili. indlela yokususa i-SS kukusebenzisa i-air flotation.Emva kokusabela kwe-dosing, amanzi amdaka angena kwindawo yokuxuba ye-air flotation system kwaye adibane namanzi akhutshweyo achithwayo, okwenza ukuba iiflocs zibambelele kwiibhubhu ezintle ngaphambi kokungena kwindawo yomoya.Phantsi kwentshukumo yokunyakazela komoya, iiflokhi zidada kumphezulu wamanzi zenze umgquba.Amanzi acocekileyo akumaleko asezantsi aqukuqela ukuya kwitanki yamanzi acocekileyo ngokusebenzisa umqokeleli wamanzi, kwaye inxalenye yawo ibuyela umva ukuze isetyenziswe igesi enyibilikisiweyo.Amanzi aseleyo acocekileyo aphuma ngezibuko lokuphuphuma.Emva kokuba i-slag edadayo kumphezulu wamanzi wetanki ye-flotation yomoya iqokelelana ukuya kubukhulu obuthile, ikhutshelwa kwitanki ye-sludge ye-air flotation nge-scraper ye-foam kwaye ikhutshwe.
