Zigawo za membrane za nembanemba za low-pressure reverse osmosis (RO).

Chinthu chatsopano cha membrane chapangidwa kuti chizigwira ntchito mocheperapo kusiyana ndi zitsanzo zakale, kupulumutsa mphamvu ndi kuchepetsa ndalama.Izi zili choncho chifukwa kupanikizika kochepa komwe kumafunika kuti agwiritse ntchito dongosololi kumatanthauza kuti mphamvu yochepa imafunika kukankhira madzi kupyolera mu nembanemba, zomwe zimapangitsa kuti zikhale zotsika mtengo komanso zopanda mphamvu.

Reverse osmosis ndi njira yoyeretsera madzi yomwe imachotsa zonyansa m'madzi kudzera mu nembanemba yomwe imatha kutha.Kuthamanga kwakukulu kumafunika kukakamiza madzi kupyolera mu nembanemba, yomwe ingakhale yokwera mtengo komanso yowonjezera mphamvu.Makina atsopano otsika kwambiri a RO, komabe, adapangidwa kuti achepetse ndalamazi ndikuwonjezera magwiridwe antchito.

Chotsitsa chochepa cha RO chimagwira ntchito mokakamiza pafupifupi 150psi, yomwe ili yotsika kwambiri kuposa 250psi yofunikira ndi mitundu yakale.Kutsika kwapang'onopang'ono kumeneku kumatanthawuza kuti mphamvu zochepa zimafunika kuti zigwiritse ntchito dongosolo, zomwe pamapeto pake zimamasulira kuchepetsa ndalama zogwirira ntchito.

Kuphatikiza apo, mawonekedwe otsika a RO amalonjeza kupereka madzi abwinoko kuposa mitundu yakale, chifukwa cha kapangidwe kake kapadera.Chinthu chatsopano cha nembanemba chimakhala ndi mainchesi okulirapo kuposa zitsanzo zam'mbuyomu, zomwe zimapangitsa kuti madzi aziyenda komanso kusefa bwino.Kuonjezera apo, pamwamba pa nembanemba ndi yunifolomu komanso yosalala, zomwe zimathandiza kuti zisawonongeke komanso zowonongeka, zomwe zimapangitsa kuti zikhale zosavuta kusunga ndi kupititsa patsogolo moyo wa nembanemba.

Ubwino wina wofunikira wa chinthu chotsika kwambiri cha RO ndi kusinthasintha kwake.Itha kugwiritsidwa ntchito pazinthu zosiyanasiyana, kuchokera kumankhwala amadzi am'mafakitale kupita kukupanga madzi akumwa akumwa.Kusinthasintha kumeneku ndi chifukwa cha mapangidwe ake abwino kwambiri, omwe amachititsa kuti azitha kuchotsa zonyansa kuchokera kumadzi ambiri.

Kupanga kachidutswa kakang'ono ka RO kamene kamakhala ndi mphamvu yotsika kumayimira kupambana kwakukulu pazamankhwala amadzi ndipo kungathe kusintha momwe timachitira madzi.Amapereka njira yotsika mtengo, yogwiritsira ntchito mphamvu komanso yothandiza kwambiri yothetsera madzi, ndikupangitsa kuti ikhale yofunika kwambiri pa njira iliyonse yopangira madzi.

Chinthu chatsopano cha membrane chalandilidwa kale bwino ndi akatswiri amakampani, omwe adayamika bwino kwake komanso kuchita bwino.Ukadaulo ukuyembekezeka kuchulukirachulukira m'zaka zikubwerazi, popeza makampani ambiri amayang'ana njira zochepetsera ndalama ndikuwonjezera magwiridwe antchito pamakina awo opangira madzi.

Pomaliza, kupangidwa kwa chinthu chochepa kwambiri cha RO ndi chitukuko chosangalatsa pankhani yaukadaulo wamankhwala amadzi.Amalonjeza kupereka njira yotsika mtengo komanso yopatsa mphamvu yopangira madzi kuposa zitsanzo zam'mbuyomu, komanso kupereka madzi apamwamba kwambiri.Chifukwa chake, yakhazikitsidwa kukhala chisankho chodziwika bwino pamakina opangira madzi padziko lonse lapansi.
