Ishishini: Unyango kunye nokusetyenziswa kwakhona kwamanzi amdaka epaki yezimboni
Imingeni: Iziphumo ezingahambelaniyo ngaphambi konyango zikhokelele ekuvalekeni rhoqo kwenkqubo ye-membrane elandelayo, nto leyo ebangele iindleko eziphezulu zokugcinwa.
I. Imvelaphi yabathengi kunye neengongoma zentlungu eyintloko
Umthengi wethu liqumrhu lolawulo lokusebenza kwepaki enkulu yemizi-mveliso. Ukuze ifezekise iinjongo zayo zophuhliso oluzinzileyo, le paki ityale imali kwinkqubo yokuhlaziya amanzi amdaka ephucukileyo, ejolise ekusebenziseni amanzi amdaka acociweyo kwimizi-mveliso ukwenza i-park greening, ukuhlamba iindlela, kunye nokuhlaziya amanzi enqaba okupholisa. Nangona kunjalo, ukusukela oko yasebenza, iyunithi yokucubungula i-membrane (RO reverse osmosis) yale nkqubo iye yahlangabezana nokuvaleka okungenakuguqulwa kunye nokungcola, okubangele ukwehla okukhulu komthamo wemveliso. Ukucoca rhoqo ngamakhemikhali kunye nokutshintshwa kwezinto ze-membrane kuyafuneka, okubangela iindleko eziphezulu kakhulu zokulungisa.
Emva kophando, unobangela wengxaki ukwimpembelelo yokuhluza engaguqukiyo ngexesha lesigaba sangaphambi konyango. Amanzi amdaka avela kumashishini ahlukeneyo epakini aneenxalenye ezintsonkothileyo kunye noxinzelelo lwe-suspended solids (SS) oluguquguqukayo. Inkqubo yokuqala yokuhluza isanti ayikwazi ukubamba ngokufanelekileyo amasuntswana amancinci kunye nezinto ze-colloidal, kwaye ezi zinto zingcolisayo zingena ngqo kwinkqubo ye-membrane entsonkothileyo, ekugqibeleni zikhokelela kwiingxaki ezinkulu. Umthengi ufuna ngokungxamisekileyo isisombululo sokuhluza sangaphambi konyango esisebenzayo nesizinzileyo ukubonelela "ngesambulela" esiqinileyo nesithembekileyo kwinkqubo ye-membrane ebizayo.
II. Isisombululo Sethu
Ngenxa yokuguquguquka okukhulu kumgangatho wamanzi amdaka epaki kunye nesidingo sokuqhubeka nokusebenza, sicebise isisombululo esiphuculweyo esinophawuinkqubo yokucoca ibheginjengeyunithi ephambili yonyango lwangaphambi konyango.
Ukuhambelana ngokuchanekileyo:Ngokusebenzisa uhlalutyo lomgangatho wamanzi, sikhethe eyona ndlela ifanelekileyo yokuhluza kubathengi bethu. Iingxowa zesihluzo ezinolu hlobo lokuchaneka zinokususa ngokufanelekileyo uninzi lwezinto eziqinileyo ezixhonyiweyo kunye nee-colloids emanzini angavuthwanga, zinciphisa kakhulu umthwalo wongcoliseko kwi-membrane esezantsi, ngelixa ziphepha ukuvaleka ngokukhawuleza kweengxowa zesihluzo ngenxa yokuchaneka kakhulu.
Ukuphucula amandla okulwa nokuvaleka:Ukuba kunokwenzeka ukuba kukho iioyile kunye nezinto ezixineneyo emanzini amdaka, sicebisa ukuba kusetyenziswe iingxowa zokucoca eziye zanyangwa ngokukodwa. Ezi ngxowa zokucoca azikwazi ukuvaleka, nto leyo eyandisa umjikelo wokucoca.
Ulawulo oluncinci lokusebenza nokugcinwa: Uyilo oluvula ngokukhawuleza kunye neengxowa zesihluzo ezisemgangathweni zenza inkqubo yokutshintsha ibe lula kakhulu. Abasebenzi abaqhelekileyo banokuyisingatha emva koqeqesho olufutshane, nto leyo enciphisa kakhulu ukuxhomekeka kubasebenzi abaziingcali bokulungisa.
III. Ixabiso Elibalulekileyo Elinikezelwa Kubathengi
Emva kokusetyenziswa kwale nkqubo yokucoca ngaphambi konyango, imeko yokusebenza iyonke yenkqubo yokusetyenziswa kwakhona kwamanzi amdaka epakini iye yaphucuka kakhulu:
Inkqubo ye-membrane ikhuselwe ngokupheleleyo:Ixesha lokucoca iikhemikhali kwi-RO membrane linyusiwe ukusuka kweyokuqala kanye ngenyanga ukuya kwikota nganye okanye ngaphezulu. Ubomi benkonzo obulindelekileyo bezinto ze-membrane buye bandiswa kakhulu, nto leyo esindisa ngokuthe ngqo abathengi iindleko ezinkulu zeekhemikhali kunye neendleko zokutshintsha izixhobo.
Uzinzo lokusebenza kwenkqubo luye lwaphuculwa kakhulu:Umgangatho wokungcola okucociweyo uzinzile kwaye uyalawuleka, nto leyo esombulula "ingxaki enkulu" yokusebenza kwenkqubo ye-membrane elandelayo. Ukuthembeka nokufumaneka kwenkqubo yonke yokusetyenziswa kwakhona kufikelele kwiinjongo zoyilo.
Ukunciphisa iindleko zomjikelo wobomi:Utyalo-mali kwiinkqubo zokucoca iingxowa luphantsi kakhulu kuneendleko zokutshintsha izinto ze-membrane, kwaye iindleko zokugcina izinto zemihla ngemihla nazo ziphantsi kakhulu. Abathengi babale ukuba ixesha lokubuyisela utyalo-mali (i-ROI) lifutshane kakhulu, nto leyo efumana iingenelo ezinkulu kwezoqoqosho.
Injongo yokonga amanzi ifezekiswe ngempumelelo:Ukusebenza kwenkqubo okuzinzileyo kuqinisekisile izinga lokusetyenziswa kwakhona kwamanzi amdaka, kwaye ipaki isindise inani elikhulu lemithombo yamanzi acocekileyo minyaka le, ngaloo ndlela ifezekisa ngokupheleleyo iinjongo zokukhusela okusingqongileyo kunye nokulondolozwa kwamanzi.
Uhlolo lomthengi:
"Utyalo-mali oluncinci kwinqanaba langaphambi konyango lisombulule ingxaki enkulu yokusebenza kwenkqubo yethu. Le nkqubo yokucoca efana neebhegi ifana nokunika inkqubo yethu ye-membrane 'isuti yokuzikhusela' eqinileyo. Ukuzinza kwayo kunye nokulula kokugcinwa kwayo kusishiye nombono onzulu, nto leyo esivumela ukuba sigxile kulawulo oluphambili lokusebenza kwepaki."
