Ngemva kokusebenzisa isihlanzi samanzi se-RO okwesikhashana, kungenzeka kakhulu ukuthi ukungcola kungase kuvaleke ngaphakathi kwendlu ye-RO kanye nolwelwesi lwe-RO. Ngakho-ke, kunconywa kakhulu ukuhlanza indlu kanye nolwelwesi kaningi lapho usebenzisa uhlelo lwe-RO. Kuwumkhuba omuhle njalo ukuqinisekisa ukuthi i-membrane nezindlu zigcinwa zihlanzekile ngaso sonke isikhathi, ngoba imvamisa lapho ulwelwesi lwe-RO luhlanzwa khona luhlobene kakhulu nekhwalithi yamanzi. Kulesi sihloko, sizohlinzeka ngolwazi oluningiliziwe mayelana nendlela yokuhlanza noma ukukhanyisa ulwelwesi lwe-RO ekhaya.
Lapho usebenza namanzi aqinile, usawoti omningi, amaminerali, nezinto zangaphandle ezingafuneki kungase kunqwabelene futhi kuvimbe ukuhamba kwamanzi okubushelelezi, okuphumela ekugelezeni okuncane kolwelwesi. Lokhu kungase kubangele ukwehla kwezinga lokwenqatshwa kanye nokuncipha kwekhwalithi yamanzi kusistimu yakho. Ngakho-ke, ukuhlanza ulwelwesi lwakho kuyisinyathelo esiyisisekelo kakhulu ekugcineni uhlelo lwakho nokuqinisekisa ukuthi uthola amanzi asezingeni eliphezulu ngaso sonke isikhathi.
Kunezinhlobo ezimbili zama-ejenti okuhlanza: eyodwa yokuhlanza i-calcium ne-magnesium ion, esetshenziswa ezindaweni ezinekhwalithi ephezulu yamanzi, kanti enye yokuhlanza ama-organic compounds. Ingase idalwe kusukela ekuqaleni ekhaya noma ithengwe isilungile. Ukuze wenze le nqubo yokuhlanza, qiniseka ukuthi unomhloli we-PH. Isizathu salokhu ukuthi ngenkathi sihlanza ulwelwesi, sisebenzisa i-citric acid noma i-hydrochloric acid; i-citric acid ikhiqizwa ibe yisixazululo esingu-2%, ngakho-ke inani le-PH kufanele ligcinwe cishe ku-2 - 3. Uma uhlanza izinto eziphilayo, sebenzisa i-0.1% ye-sodium hydroxide kanye ne-0.025% ye-sodium dodecyl sulfonate, hlanganisa namanzi ahlanzekile futhi ulungise inani le-PH libe ngu-11-12.
I-solvent eyodwa kuphela engasetshenziswa ngesikhathi, hhayi kokubili izincibilikisi. Ukusetshenziswa okuxubile ngeke nje kube nomthelela kodwa futhi kubangele nomonakalo ongalungiseki kulwelwesi lwe-RO. Uma ufisa ukusebenzisa kokubili izincibilikisi, qala ugeze ulwelwesi ngekhambi lokuhlanza i-calcium ne-magnesium ion cishe amahora amabili; bese uhlanza ngamanzi ahlanzekile, kulandele isisombululo sokuhlanza izinto eziphilayo. Vele, uma ukuvinjwa kubi kakhulu, vele usebenzise iphampu ye-booster ukumpompa i-reagent kugobolondo le-membrane ye-RO, ulicwilise amahora amabili, bese uyalihlanza. Ngemuva kokuhlanza, hlambulula ulwelwesi ngamanzi ahlanzekile.
Nakuba ukuhlanza i-membrane ye-RO kuwumkhuba omuhle, akuphakanyiswa ukuhlanza ulwelwesi njalo uma ukusebenza kwalo kungalungile. Siphakamisa ukushintsha ulwelwesi njengoba ukuhlanza ulwelwesi kungaba nzima uma ungawazi amakhemikhali noma izixazululo ezisetshenziswa kule nqubo.
