Amagama angundoqo: Iarhente yokususa umbala emanzini amdaka, i-flocculant yokususa umbala
Xa i-arhente yokususa umbala emanzini amdaka ifakwa kwi-tank yamanzi amdaka, kuqala i-microscopic color-catching reaction. Akukho xesha limiselweyo lokuba i-arhente iphendule ngokupheleleyo; phantsi kweemeko ezilungileyo, isebenza kwimizuzu embalwa, ngelixa phantsi kweemeko zamanzi ezinzima, yonke inkqubo ayithathi ngaphezu kwesiqingatha seyure.
Imizuzwana embalwa yokuqala emva kokuba i-arhente ingene emanzini yinqanaba lokusasazeka kunye nokuwohloka. Phantsi kwesenzo sokuhamba kwamanzi okanye ukushukuma, i-arhente isasazeka ngokukhawuleza, kwaye iimolekyuli zifunxa amasuntswana anemibala emanzini. Kwisithuba somzuzu omnye okanye emibini, ii-flocs ezincinci ziqala ukwakheka emanzini, kwaye uninzi lwezinto ezingcolisayo ezinemibala zigqibezela ukubopha kwazo kokuqala.
Imizuzu emithathu ukuya kwemihlanu elandelayo linqanaba elibalulekileyo lokuhlanganiswa nokukhula kwe-floc. Ii-floc ezincinci ziyangqubana kwaye zihlangana, zikhula ngokuqhubekayo ngobukhulu nangobunzima njengebhola yekhephu, ziqhubeka zigubungela imibala emanzini. Kweli nqanaba, isiphumo sokutshintsha umbala sokudaya okuqhelekileyo kunye namanzi amdaka asekhaya sinokufikelela ngaphezulu kwe-90%, kwaye amanzi ngokuthe ngcembe acaca ngakumbi.
Ekugqibeleni, inqanaba lokutsalwa kwenkunkuma kunye nokwahlukana liyaqala. Iiflocs ezenziweyo zihlala phantsi koxinzelelo lomhlaba, ngokubanzi zifuna imizuzu emihlanu ukuya kwelishumi ukugqiba ukwahlula udaka namanzi. Kumanzi amdaka anzima ukuwaphatha aneedayi kunye neoyile esebenzayo, ukungcola okunemibala kunzima ukukubamba, nto leyo eyandisa umjikelo wonke wokusabela ukuya kwimizuzu elishumi elinesihlanu ukuya kwengamashumi amabini.
Izinga lokusabela lichaphazeleka ziimeko ezininzi: ukushukuma okupheleleyo kukhawulezisa ukusasazwa kwe-reagent; indawo efanelekileyo ye-alkaline emzimbeni wamanzi yandisa umsebenzi we-reagent; kwaye amaqondo obushushu aphantsi acothisa intshukumo yamasuntswana, nto leyo eyandisa ixesha lokuphendula.
Ngamafutshane, kumanzi amdaka aqhelekileyo, ukongezwa kwee-flocculants ezisusa umbala kugqiba yonke impendulo kwimizuzu elishumi ukuya kwelishumi elinesihlanu, kufezekisa ukwahlulwa kwamanzi amdaka; nokuba kumanzi amdaka anemibala eqinileyo, yonke inkqubo yokususa umbala kunye nodaka ayidluli kwisiqingatha seyure. Uthotho lweempendulo ezincinci eziqhubekayo zibamba imibala emanzini amdaka ngaphakathi kodaka, zicacisa amanzi amdaka kwaye ziqinisekise ukuba ayahlangabezana nemigangatho.
