• Mvura Kurapa Basics Nzira yekusarudza iyo chaiyo RO membrane

Sarudzo uye inonzwisisika inofananidzwa yeRO membranes inotarisisa kugona kweiyo RO zvishandiso, uye kune akawanda marudzi eRO membranes pamusika, uye mitengo zvakare yakasiyana zvakanyanya. Kunze kwenhamba diki diki yezvikamu zvemamembrane akakosha ane humwe hunyanzvi hwakawedzerwa kukosha (mutengo unofashukira), mitengo yeRO mafirimu ezvakajairwa zvinhu, modhi uye mamiriro ekushandisa evazhinji vanogadzira ave pachena uye akagadzikana. Kazhinji, mutengo wero membrane inodhura zvishoma pane yepamba RO membrane, asi ine zvishoma zvishoma maererano nekugadzikana, hupenyu hwebasa, zviratidzo zvepakati (desalination rate, goho remvura, chiyero chekudzorera) nezvimwe zvakadaro.

• Mhando dzakasiyana dzemashandisirwo ezviitiko

XLP yakatevedzana: yakanyanya kuderera kumanikidza membrane element, kazhinji yakakodzera kurapwa kwemvura yakadzika yemunyu ine yakaderera yemunyu inodiwa kune yakaderera desalination rate, senge mvura yepasi, pasi pemvura, mvura yemupombi uye mvura yemunisiparati ine munyu weisingasviki 1000ppm, kunyanya yakakodzera padanho rechipiri desalination yezvikamu zviviri-reverse osmosis lure. Inonyanya kushandiswa munzvimbo dzakasiyana-siyana dzakadai semvura yakacheneswa yezviyero zvakasiyana, boiler yekugadzira-up mvura, kugadzira chikafu uye maindasitiri ekugadzira mishonga.

• Basic data reverse osmosis membrane

Kurambwa kwemunyu: Mwero wekubvisa munyu weRO membrane element wakatemerwa panguva yekugadzirwa kwayo, uye mwero wekubvisa munyu unoenderana nekuwanda kweiyo yakanyanya kutetepa desalnation layer pamusoro peRO membrane element, denser desalination layer, kukwirisa mwero wekubvisa salination, uye kuderera kwekugadzirwa kwemvura. Iyo desalination rate yeRO membrane yezvinhu zvakasiyana inonyanya kutariswa nechimiro uye huremu hwemamorekuru echinhu, chiyero che desalination cheyakakwira-valent ion uye yakaoma monovalent ion inogona kudarika 99%, uye desalination rate yemonovalent ion senge sodium ion, potassium ions, uye chloride ions yakadzikira zvishoma, asi inogona zvakare kupfuudza iyo yakaderera iyo kemikari membrane (yakaderera 98%). desalination rate yeRO membrane) Muyero wekubvisa weorganic matter ine huremu hwemamorekuru hunodarika 100 hunogonawo kuva pamusoro pe98%, asi mwero wekubvisa weorganic matter ine huremu hwemamorekuru hwepasi pe100 hwakaderera.

Kuverengera nzira yekurambwa kwemunyu uye munyu permeability yeRO membrane:

Munyu permeability yeRO membrane = RO membrane permeate concentration / pesvedzero yemvura yakadzika × 100%

Desalination rate yeRO membrane = (munyu wemukati wemvura inoyerera / munyu wemukati wemvura ine simba ye1-RO membrane) × 100%

Kugadzirwa Kwemvura: GPD = Magarita (US)/Zuva, GFD = Magarita (US)/pa sikweya tsoka/zuva

Mvura inobereka yeRO membrane - inoreva simba rekubudisa mvura yeRO system, kureva, chiyero chemvura inopfuura nepakati peRO membrane pane imwe nguva, inowanzoratidzwa mumatani paawa kana marita pazuva. 1 garoni (US) = marita 3.785, cubic meter 1 = marita 264.2 (US).

Kupindirana kweRO membrane zvakare chiratidzo chakakosha chegoho remvura yeRO membrane element. Inoreva kuyerera kweyero permeate per unit membrane area, inowanzo ratidzwa mumagaloni paskweya tsoka pazuva (GFD). Yakawandisa osmotic kuyerera mwero inotungamira kune inomhanyisa kuyerera kwemvura perpendicular kumusoro kweRO membrane, iyo inowedzera membrane fouling.

Kudzvinyirira (kunyanya kushanda kushanda): 1 kg pressure = 1 bar ≈ 14.5 psi = musoro 10m (pombi)

PSI (Pounds per square inch) iyuniti yekuyera. P inoreva pondo, S inoreva sikweya, ini ndinoreva masendimita, uye United States inoshandiswa kushandisa psi sechikamu, zvinoreva pound-simba per square inch.

Kumanikidza kwekushandisa kweRO membranes kunowanzo pakati pe2-20MPa, zvichienderana nezvinhu zvakaita serudzi, saizi, zvinhu, uye mhando yemvura yechinhu che membrane. Kazhinji, iyo yakakwirira yekushanda kweiyo RO membrane, iyo inokwirisa iyo desalination inoshanda, asi zvakare inowedzera njodzi yekupfeka chinhu uye membrane kushatisa. Naizvozvo, kumanikidza kwekushanda kweiyo RO membrane kunoda kudzorwa mukati meiyo inonzwisisika renji kuti ive nechokwadi chekugadzikana kwayo uye hupenyu

Mumashandisirwo anoshanda, iyo inoshanda yekumanikidza yeRO membranes inoda kugadziridzwa zvinoenderana nemhando yemvura uye kurapwa zvinodiwa. Semuyenzaniso, mukubvisa mvura yemugungwa, kushanda nesimba kweRO membranes kunowanzo kuve pakati pe5-10MPa kuti iwane yakakwira desalination kunyatsoita uye hupenyu hurefu. Mumaindasitiri ekuchenesa mvura yetsvina, RO membranes inogona kushanda nedzvinyiriro dzepamusoro kubata nemhando yemvura yakaoma uye kuwanda kwemunyu.

Recovery Rate: RO membrane kudzoreredza - inoreva chikamu chemvura yekudyisa muRO membrane system inoshandurwa kuita permeate kana permeate. Inotemerwa zvichienderana nemhando ye pretreated influent mvura uye zvinodiwa zvemvura zve RO system. Chiyero chekudzorera che RO membrane system inotarirwa panguva yekugadzira.
Recovery rate yeRO membrane = (permeate flow rate yeRO membrane / influent flow) ×100%
