Isihlukanisi sika-oyela - imishini ehlanza ukungcola komhlaba kusuka emikhiqizweni ecwengekile ngodaka lwayo. Ingqikithi yesenzo sayo ukukhishwa kwamanzi angcolile kusuka kumikhiqizo elungisiwe ngomehluko wobuningi bezinto. Ngenxa yesenzo sale divayisi, isimo samapayipi sifika kumanani ajwayelekile, ngemuva kwalokho kungenzeka ukuwathumela emzimbeni wamanzi.
Inhloso nezinhloso zomdobi kawoyela
Isihlukanisi sikawoyela sanamuhla sihlanza amanzi angcolile asekhaya, kanye namanzi angcolile avela ezinkampanini zokuhluza uwoyela, umkhakha wopende nowenziwe nge-varnish. Ngaphandle kokufakwa kwesicupho sikawoyela, akunakwenzeka ukuvula nokusebenza egalaji likaphethiloli, ukuwashwa kwezimoto, izakhiwo zobunjiniyela, imboni yezokuthutha, namanye amaphuzu angangcolisa imvelo ngemikhiqizo ehlanjululwe ngoyela. Uma ibhizinisi lithutha uwoyela, liphoqelekile ukuhlanza ukungcola. Inhloso yokuhlanzwa kwamanzi kungenzeka ukuthi isetshenziswe futhi, isuswe ngokuphelele ukungcola ngokucutshungulwa okulandelayo, ukuncipha okukhulu kokuqukethwe kokungcola kumanzi angcolile.
Ukuhlungwa okuphezulu kakhulu kwemikhiqizo kawoyela isicupho sikawoyela esingasingatha lapho kuhlanzwa indle yesiphepho akuyona ngaphezu kwe-120 mg nge-1 litre. Uma le pharamitha iphakeme, kuzodingeka kwenziwe uhlelo olwehlukile lokuhlanzwa kwamanzi angcolile.
Ibhokisi lodoti ligeza ngaphambili isiphepho, bese kuthi ubuningi buthunyelwe kumgibe kawoyela. Ukukhethwa kwemodeli kuncike kumthamo wokungcola okufanele uphathwe. Amadivayisi awasetshenziswanga ngokuzimela, ngoba lokhu akunakwenzeka. Ziyizigaba ezithile zokuhlanza okuyinkimbinkimbi. Akunakwenzeka ukufeza umphumela omuhle ngaphandle kokubamba iqhaza kwabathakathi. Ama-sorbents yi-peat, umlotha, i-coke, i-silica gel, ubumba olusebenzayo, i-carbon esebenzayo. Ngokuhlanzwa okwengeziwe, izinhlelo zezitshalo zihlala ziqukethe imishini yokuhlanza ulwelwesi.
Izindlela zokwehlukanisa ukungcola
Ukungcola okuvela kumikhiqizo elungisiwe kuhlukaniswe ngale ndlela elandelayo:
- amanzi ahlala egumbini elilodwa, izingxenye zesihlabathi nodoti ziyahlukaniswa;
- inqwaba yemfucuza ibese iqondiswa kwelinye igumbi elinesisefo sokuhlanganisa ukuhlanganisa izinhlayiya ezinhle eziqukethe uwoyela kwifilimu. Ngemuva kokufinyelela ku-150 mm ubukhulu, kunikezwa isignali, ngemuva kwalokho ukukhishwa kwamafutha kususwa ngosizo lwabasebenzi;
- ukuhlanzwa kokugcina kwenziwa ngezihlungi ze-sorption.
Umzimba wedivayisi wenziwe nge-fiberglass eqinisiwe epulasitiki. Umgibe kawoyela uhlanza amanzi angcolile ageleza kuwo ngamandla adonsela phansi, ngakho-ke akukho ukuqapha okudingekayo.
