Amagama angukhiye: I-ejenti yokususa umbala emanzini angcolile, i-flocculant yokususa umbala
Uma i-ejenti yokususa umbala emanzini amdaka ifakwa ethangini lamanzi amdaka, kuqala ukusabela okubonakalayo kombala. Asikho isikhathi esinqunyiwe sokuba i-ejenti isabele ngokuphelele; ngaphansi kwezimo ezinhle, iqala ukusebenza ngemizuzu embalwa, kuyilapho ngaphansi kwezimo zamanzi eziyinkimbinkimbi, yonke inqubo ayithathi isikhathi esingaphezu kwesigamu sehora.
Imizuzwana embalwa yokuqala ngemva kokuba i-ejenti ingene emanzini yisigaba sokusabalala kanye nokuwohloka. Ngaphansi kwesenzo sokugeleza kwamanzi noma ukushukuma, i-ejenti ihlakazeka ngokushesha, futhi ama-molecule amunca izinhlayiya ezinemibala emanzini. Cishe umzuzu owodwa noma emibili, ama-floc amancane aqala ukwakheka emanzini, futhi iningi lokungcola okunemibala liqeda ukubopha kwawo kokuqala.
Imizuzu emithathu kuya kwemihlanu elandelayo yisigaba esibalulekile sokuhlanganiswa nokukhula kwe-floc. Ama-floc amancane ayashayisana futhi ahlangane, akhula njalo ngobukhulu nangesisindo njengebhola leqhwa, ehlanganisa njalo imibala emanzini. Kulesi sigaba, umphumela wokushintsha umbala wokudaya okuvamile kanye namanzi angcolile asekhaya ungafinyelela ngaphezu kuka-90%, futhi amanzi kancane kancane acaca ngokusobala.
Ekugcineni, isigaba sokuthungwa kanye nokwehlukaniswa siyaqala. Ama-floc akhiwe ahlala phansi ngamandla adonsela phansi, ngokuvamile adinga imizuzu emihlanu kuya kweyishumi ukuqedela ukuhlukaniswa kodaka namanzi. Kumanzi amdaka okunzima ukuwaphatha aqukethe udayi namafutha asebenzayo, ukungcola okunemibala kunzima ukubamba, okwandisa umjikelezo wonke wokusabela ube yimizuzu eyishumi nanhlanu kuya kwengamashumi amabili.
Izinga lokusabela lithintwa yizimo eziningi: ukushukuma okuphelele kusheshisa ukusabalala kwe-reagent; indawo efanelekile ye-alkaline emzimbeni wamanzi yandisa umsebenzi we-reagent; kanti amazinga okushisa aphansi anciphisa ukunyakaza kwezinhlayiya, okwandisa isikhathi sokusabela.
Ngamafuphi, emanzini angcolile avamile, ukungezwa kwama-flocculant asusa umbala kuqeda yonke impendulo zingakapheli imizuzu eyishumi kuya kweyishumi nanhlanu, kufezwe ukuhlukaniswa kwamanzi angcolile; ngisho nasemanzini angcolile anombala oqinile, yonke inqubo yokususa umbala kanye nokungcola ngokuvamile ayidluli isigamu sehora. Uchungechunge lwezimpendulo ezincane eziqhubekayo lubamba imibala emanzini angcolile ngaphakathi kodaka, lucacise amanzi angcolile futhi luqinisekise ukuthi ahlangabezana nezindinganiso.
