Emva kokusebenzisa i-RO yokucoca amanzi okwethutyana, kunokwenzeka kakhulu ukuba ukungcola kunokuvala ngaphakathi kwendlu ye-RO kunye ne-RO membrane. Ke, kucetyiswa kakhulu ukucoca indlu kunye ne-membrane rhoqo xa usebenzisa inkqubo ye-RO. Kungumkhwa omhle wokuhlala uqinisekisa ukuba i-membrane kunye nezindlu zigcinwa zicocekile ngamaxesha onke, ekubeni i-frequency apho i-RO membrane ihlanjululwa khona ihambelana kakhulu nomgangatho wamanzi. Kweli nqaku, siza kubonelela ngolwazi olucacileyo malunga nendlela yokucoca okanye ukukhanyisa i-RO membrane ekhaya.
Xa kusetyenzwa namanzi aqinileyo, iityuwa ezahlukahlukeneyo, iiminerali, nezinto zangaphandle ezingafunekiyo zinokuqokelelana zize zivale indlela egudileyo yamanzi, nto leyo ekhokelela kumlinganiselo ophantsi wokuhamba kwenwebu. Oku kunokubangela ukwehla kwezinga lokwaliwa kunye nokuhla komgangatho wamanzi kwisixokelelwano sakho. Ke, ukucoca inwebu yakho linyathelo elisisiseko kakhulu ekugcineni inkqubo yakho kunye nokuqinisekisa ukuba ufumana awona manzi asemgangathweni ngawo onke amaxesha.
Kukho iindidi ezimbini zokucoca: enye yokucoca i-calcium kunye ne-magnesium ion, esetyenziswa kwiindawo ezinomgangatho ophezulu wamanzi, kunye nokucoca i-organic compounds. Inokudalwa ukusuka ekuqaleni ekhaya okanye ithengwe sele ilungile. Ukwenza le nkqubo yokucoca, qiniseka ukuba unomvavanyi we-PH. Isizathu salokhu kukuba ngelixa sihlambulula i-membrane, sisebenzisa i-citric acid okanye i-hydrochloric acid; i-citric acid iveliswa kwisisombululo se-2%, ngoko ke ixabiso le-PH kufuneka ligcinwe malunga ne-2 - 3. Ukuba ukucoca izinto eziphilayo, sebenzisa i-0.1% ye-sodium hydroxide kunye ne-0.025% ye-sodium dodecyl sulfonate, xuba ngamanzi ahlambulukileyo kwaye ulungelelanise ixabiso le-PH malunga ne-11-12.
Sinye kuphela isinyibilikisi esinokusetyenziswa ngexesha, hayi zombini izinyibilikisi. Ukusetyenziswa okuxutyiweyo akuyi kuba nefuthe kuphela kodwa kubangele umonakalo ongenakuguqulwa kwi-membrane ye-RO. Ukuba unqwenela ukusebenzisa zombini i-solvents, qala uhlambe i-membrane nge-calcium kunye ne-magnesium ion yokucoca isisombululo malunga neeyure ezimbini; emva koko uhlambulule ngamanzi acocekileyo, ulandelwe sisisombululo sokucoca ngendalo. Ewe kunjalo, ukuba uthintelo lunzulu kakhulu, sebenzisa nje impompo ye-booster ukumpompa i-reagent kwiqokobhe le-membrane ye-RO, yicwilise iiyure ezimbini, emva koko uyicoce. Emva kokucoca, hlambulula i-membrane ngamanzi acocekileyo.
Nangona ukucoca i-membrane ye-RO kuyindlela efanelekileyo, akukhuthazwa ukuba uhlambulule i-membrane rhoqo ukuba ukusebenza kwayo kubi. Siphakamisa ukubuyisela i-membrane ekubeni ukucoca i-membrane kunokuba nzima ukuba awuqhelananga neekhemikhali okanye izisombululo ezisetyenziswa kwinkqubo.
