Kwinkqubo yokucoca amanzi amdaka, ukusebenzisa isixhobo sokucoca amanzi kuphela kudla ngokungaphumeleli ekufezekiseni umphumo. I-Polyacrylamide (PAM) kunye ne-polyaluminum chloride (PAC) zihlala zisetyenziswa kunye kwinkqubo yokucoca amanzi. Ngayinye ineempawu kunye nemisebenzi eyahlukileyo. Zisetyenziswa kunye ukuvelisa iziphumo ezingcono zokucubungula amanzi.
1. I-Polyaluminum chloride(i-PAC):
- Umsebenzi oyintloko yi-coagulant.
- Ingawuthomalalisa ngempumelelo umbane wee-particles ezixhonyiweyo emanzini, nto leyo ebangela ukuba ii-particles zihlangane zenze ii-flocs ezinkulu, nto leyo eyenza kube lula ukutyibilika nokucoca.
- Ifanelekile kwiimeko ezahlukeneyo zomgangatho wamanzi kwaye inefuthe elihle ekususeni ukufuma, umbala kunye nezinto eziphilayo.
2. I-Polyacrylamide(PAM):
- Umsebenzi oyintloko kukuncedisa i-flocculant okanye i-coagulant.
- Inganyusa amandla kunye nomthamo we-floc, okwenza kube lula ukwahlukana namanzi.
- Kukho iintlobo ezahlukeneyo ezifana ne-anionic, i-cationic kunye ne-non-ionic, kwaye ungakhetha uhlobo olufanelekileyo ngokweemfuno zakho zonyango lwamanzi.
Isiphumo sokusebenzisa kunye
1. Ukuphucula impembelelo yokujiya: Ukusetyenziswa okudibeneyo kwe-PAC kunye ne-PAM kunokuphucula kakhulu impembelelo yokujiya. I-PAC kuqala inciphisa amasuntswana axhonyiweyo emanzini ukuze enze ii-flocs zokuqala, kwaye i-PAM iphucula ngakumbi amandla kunye nomthamo wee-flocs ngokuzibopha kunye nokuzifunxa, okwenza kube lula ukuzinza nokuzisusa.
2. Ukuphucula ukusebenza kakuhle konyango: Ukusebenzisa i-PAC enye okanye i-PAM kusenokungaphumeleli kwisiphumo sonyango esingcono, kodwa indibaniselwano yezi zimbini inokunika ithuba elipheleleyo kwiingenelo zazo, iphucule ukusebenza kakuhle konyango, inciphise ixesha lokuphendula, inciphise umthamo weekhemikhali, ngaloo ndlela inciphise iindleko zonyango.
3. Ukuphucula umgangatho wamanzi: Ukusetyenziswa kunye kunokususa izinto eziqinileyo ezixhonyiweyo, ukudumba kunye nezinto eziphilayo emanzini, kwaye kuphucule ukucaca kunye nobunyulu bomgangatho wamanzi amdaka.
Amanyathelo okuzikhusela ekusebenziseni okusebenzayo
1. Ulandelelwano lokudibanisa: Ngokwesiqhelo i-PAC yongezwa kuqala ukuze kuqiniswe i-preliminary, ize emva koko kongezwe i-PAM ukuze kuqiniswe i-flocculation, ukuze kubekho ukusebenzisana okukhulu phakathi kwezi zimbini.
2. Ulawulo lomthamo: Umthamo we-PAC kunye ne-PAM kufuneka uhlengahlengiswe ngokweemeko zomgangatho wamanzi kunye neemfuno zonyango ukuze kuthintelwe inkunkuma kunye nemiphumo emibi ebangelwa kukusetyenziswa ngokugqithisileyo.
3. Ukubeka iliso kumgangatho wamanzi: Ukubeka iliso kumgangatho wamanzi kufuneka kwenziwe ngexesha lokusetyenziswa, kwaye umthamo weekhemikhali kufuneka uhlengahlengiswe ngexesha elifanelekileyo ukuqinisekisa isiphumo sonyango kunye nomgangatho wokungcola.
Ngamafutshane, ukusetyenziswa okudibeneyo kwe-polyacrylamide kunye ne-polyaluminum chloride kunokuphucula kakhulu isiphumo sokunyanga amanzi, kodwa idosi ethile kunye nendlela yokusebenzisa kufuneka ilungiswe ngokwemeko yokwenyani.
