I-Reverse osmosis (RO) ibhekiselele kubuchwepheshe obucoca amanzi ngokuwatyhala ngenwebu engakwazi ukungena ngaphakathi phantsi koxinzelelo oluphezulu.I-membrane ye-RO yintlupheko encinci yezinto zokucoca ezahlula i-arhente ezingcolisayo kunye neetyuwa ezinyibilikayo kumanzi okusela.Iqulathe iileya ezintathu, ezizezi iwebhu ye-polyester yokuxhasa, i-micro-porous polysulfone interlayer kunye ne-ultra-thin polyamide barrier layer.Ezi nwebu zingasetyenziswa kuzo zombini iinkqubo zoshishino kunye nokufumana amanzi okusela.Kule mihla, ziya zisanda ukusetyenziswa kwihlabathi lonke ukucocwa kwamanzi, njengoko inkqubo ye-RO ibonelela ngendlela ehambelana nokusingqongileyo kunye nengabizi kakhulu kwiindlela ezisetyenziswa ngokwesiqhelo ezinje ngokucoca.Kodwa abantu abakaqhelani ngokupheleleyo namagama asetyenziswayo kwaye bawuqonde ngokupheleleyo umahluko phakathi kweentlobo ze-ro membranes.
Kwinqaku lanamhlanje, siza kwabelana ngokufutshane ngamanye amagama asetyenziswa kakhulu kunye nendlela umahluko phakathi kwe-RO membranes.Iimbrane ze-HID zihlelwa ngokohlobo lwe-membrane, ukusetyenziswa kwe-membrane, ubungakanani kunye nokusebenza.Kwiwebhusayithi yethu, inwebu ihlelwa ikakhulu ngokweendidi ezintathu kusetyenziswa i-membrane (GPD).Sihlela ii-membrane zethu ngokobungakanani benkqubo yesicelo kunye noluhlu lwazo lwe-GDP.Kwiindawo zokuhlala ze-ro membranes kwi-HID, uluhlu lwe-GPD lwe-50 - 200 kwaye lunokusingatha uluhlu loxinzelelo lwe-65psi ukuya kwi-200psi ephezulu.Sineemodeli ezibanzi okanye ezi membrane kwaye ungajonga iyunithi yethu kwiwebhusayithi yethu.Ezi nwebu zifanelekile kwaye zicetyiswa ukuba zisetyenziswe kwiinkqubo ezincinci zasekhaya.ngenxa yoluhlu oluphantsi loxinzelelo kunye namanqanaba e-gpd.
Kubainwebu rorhwebo kwi HID, Uluhlu lwe-GPD lwe-200 - 1000 kwaye lunokusingatha uluhlu loxinzelelo lwe-65psi ukuya kubuninzi be-200psi.Sikwanayo imodeli ebanzi kwezi inwebu.Ezi membrane zifanelekile ukusetyenziswa kwiindawo zikawonkewonke okanye izakhiwo zeofisi, izibhedlele, izikolo, iifektri, iilabhoratri kuba i-GPD yale mibhobho inamandla aphezulu kuneendawo zokuhlala.Ngokuqhelekileyo zisetyenziselwa ukukhupha ityuwa kumanzi angaphezulu, amanzi aphantsi komhlaba, amanzi etephu, ibrackish enetyuwa phantsi kwe-2000ppm.Iqela lesithathu ziinwebu zamashishini, ezi zikhulu ngobukhulu, iGPD, kwaye ziyilelwe iinkqubo ezinkulu.Ukusuka kwi-780 - 11000 iilitha ngosuku, ezi zingasetyenziselwa ukukhutshwa kwetyuwa kumanzi olwandle kunye noxinzelelo oluphezulu lwamanzi ane-brackish kwaye inokumelana noluhlu loxinzelelo lwe-150psi ukuya kwi-600psi ephezulu.Siza kwabelana ngolwazi oluthe kratya lwecandelo ngalinye kwinqaku lethu elilandelayo.
Amagama aphambili asetyenziswa kwi- reverse osmosis
Ukubuyisela - ipesenti yenkqubo ye-membrane yokutya kwamanzi avela kwinkqubo njengamanzi emveliso okanye "i-permeate".
Ukwala - ipesenti yoxinaniso lwe-solute lususwe kumanzi okutya kwenkqubo ngenwebu.
Ipaseji - ngokuchaseneyo "nokugatywa", isicatshulwa yipesenti yezinto ezichithwayo (ukungcola) kumanzi okutya avunyelwe ukuba adlule kwi-membrane.
Ukuqukuqela - Ukuqukuqela komxhesho ngumlinganiselo wamanzi wokuxheshisela aziswa kwi-membrane element okanye inkqubo ye-membrane, edla ngokulinganiswa ngeegaloni ngomzuzu (gpm).
Concentrate flow - yireyithi yokuqukuqela amanzi feed non-permeated ephuma inwebu element okanye inwebu inkqubo.
I-Flux - umlinganiselo we-permeate ohanjiswe ngeyunithi yendawo ye-membrane, ngokuqhelekileyo ilinganiswa ngeegaloni ngonyawo lwesikwere ngosuku (gfd) okanye iilitha ngemitha yesikwere kunye neyure (L / m2h).
I-Permeate - imveliso ecocekileyo yamanzi eveliswa yinkqubo ye-membrane.
I-Total Dissolids Solids (TDS) - idla ngokuchazwa njenge-mg/lor ppm (iinxalenye ngesigidi).
