Mazano mashanu ekuwedzera hupenyu hweRO Membrane uye kuchengetedza mari

1. Iva nechokwadi chekuti mvura yekudya inorapwa zvakanaka usati watanga kucheneswa

Hunhu hwemvura yekudyisa ndicho chinhu chikuru chinokanganisa mashandiro eRO membrane uye hupenyu hwebvudzi. Zvinhu zvisingadiwe mumvura isina kucheneswa, zvakaita sezvinhu zvakanyungudutswa, macolloid, organic matter, uye chlorine, zvinogona kukonzera kukuvara kusingagadzirisiki kumembrane. Saka, kuita maitiro akazara ekurapa kwekutanga kwakakosha.

Kutanga, isa sediment filter kuti ubvise zvidimbu zvakakura zvakaita sejecha, silt, uye ngura, izvo zvinogona kukwenya pamusoro pe membrane. Chechipiri, shandisa activated carbon filter kubvisa chlorine uye organic compounds - chlorine, kunyanya, inogona oxidize membrane material, zvichikonzera kudzikira kukuru kwekushanda kwe desalination. Kune mvura ine turbidity yakawanda kana colloidal content, kuwedzera coagulation uye flocculation step kunogona kuwedzera kushanda zvakanaka kwe pretreatment. Nekuona kuti mvura yekudyisa inosangana nezvinodiwa zve RO membrane, unogona kuderedza njodzi yekusvibiswa kwe membrane uye kuisa hwaro hwakasimba hwekuwedzera hupenyu hwayo hwekushanda.

2. Chengetedza Magadzirirwo Akakodzera Ekushanda

Kushanda kweRO system mukati mehuwandu hwema parameter anokurudzirwa kwakakosha kudzivirira kushushikana kwakanyanya pa membrane. Ma parameter akakosha ekutarisa anosanganisira kumanikidzwa kwekushanda, tembiricha, uye mwero wekupora.

Kumanikidzwa kwakanyanya kwekushanda kunogona kukurumidzisa kuora kwemembrane uye kuwedzera kushandiswa kwesimba. Gara uchitevera nhungamiro dzemugadziri wemhando yepamusoro yekumanikidzwa. Kupisa kunokanganisawo mashandiro emembrane—tembiricha yakakwira inogona kuvandudza kufamba kwemvura asi inogonawo kuwedzera mwero wekukweva uye kusvibisa. Nokudaro, zvakakosha kudzora tembiricha yemvura yekudyisa mukati mehuwandu hwakakodzera, kazhinji pakati pe25°C ne35°C. Pamusoro pezvo, mwero wekudzoserwa (chiyero chemvura yechigadzirwa kumvura yekudyisa) haufanirwe kunge wakanyanya kukwira. Mwero wekudzoserwa wakakwira unogona kutungamira mumunyu wakawanda uye kusvibiswa pamusoro pemembrane, zvichiwedzera njodzi yekukweva. Kugadzirisa mwero wekudzoserwa zvichienderana nemhando yemvura uye dhizaini yesystem kunogona kuenzana nekushanda zvakanaka kwekugadzirwa kwemvura uye kudzivirira membrane.

3. Shandisa Maitiro Ekuchenesa Akajairika uye Akakodzera

Kunyangwe kana paine mushonga unoshanda usati wagadzirwa, kusvibiswa kweganda hakudzivisiki nekufamba kwenguva. Kuchenesa panguva yakakodzera kunogona kubvisa zvinhu zvinosvibisa uye kudzoreredza mashandiro eganda. Zvisinei, kucheneswa kusina kunaka kunogona kukonzera kukuvara kwakanyanya kweganda, saka zvakakosha kutevedzera nzira dzesainzi dzekuchenesa.

Chekutanga, gadzira purogiramu yekuchenesa nguva dzose zvichienderana nezvinoratidza mashandiro emuchina, zvakaita sekudzikira kwemvura, kuwedzera kwekumanikidzwa kwekushanda, kana kudzikira kwehuwandu hwekubvisa munyu. Chechipiri, sarudza mushonga wekuchenesa wakakodzera zvichienderana nerudzi rwekusvibisa—semuenzaniso, shandisa mishonga yekuchenesa ine acidic kubvisa makwara asina kugadzirwa (akadai secalcium carbonate) uye mishonga yekuchenesa ine alkaline kubvisa kusvibisa kweorganic uye biofouling. Dzivisa kushandisa makemikari akaoma asingaenderane nezvinhu zve membrane. Munguva yekuchenesa, dzora huwandu hwemushonga wekuchenesa, tembiricha, uye nguva yekuchenesa zvakanyatsonaka. Mushure mekuchenesa, sukurudza membrane zvakanaka nemvura yakachena kuti ubvise chero mushonga wekuchenesa wakasara, izvo zvinogona kukonzera kukuvara kwenguva refu kana zvikasiyiwa.

4. Tarisa uye Udzore Hunhu hweMvura Nguva Dzose

Kuramba uchitarisa mvura yekudyisa, mvura yechigadzirwa, uye hunhu hwemvura yakasanganiswa kunogona kubatsira kuona matambudziko anogona kuitika nekukurumidza uye kutora matanho ekudzivirira nekukurumidza. Zviratidzo zvikuru zvekutarisa zvinosanganisira turbidity, pH value, chlorine content, total dissolved solids (TDS), uye conductivity.

Isa zvishandiso zvekutarisa online kuti utevere zviratidzo izvi panguva chaiyo. Semuenzaniso, turbidity meter inogona kukuzivisa nezvekuwedzera kwezvimedu zvakasungirirwa mumvura yekudyisa, zvichikukurudzira kuti utarise uye utsive firita yekugadzirira usati washandisa. pH meter inogona kubatsira kuchengetedza pH yemvura yekudyisa iri mukati mehuwandu hwakakodzera (kazhinji 6.5 kusvika 8.5) kudzivirira ngura kana kukura kwemembrane. Kugara uchiyedza TDS uye conductivity yemvura yechigadzirwa kunogona kuratidza mashandiro ekubvisa munyu mumembrane - chero kuwedzera kamwe kamwe kunogona kuratidza kukuvara kwemembrane kana kusvibiswa. Nekuramba wakangwarira nezvekuchinja kwemhando yemvura, unogona kugadzirisa matambudziko asati awedzera, nokudaro uchidzivirira membrane uye kuderedza mari yekugadzirisa.

5. Shandisa Maitiro Akakodzera Ekudzima uye Ekuchengetera Zvinhu

Kuvharwa nekuchengetwa zvisina kunaka kweRO system kunogona kukonzera kukuvara kwakanyanya kwemembrane, kunyanya panguva yekusashanda kwenguva refu. Saka, kutevedzera nzira dzakakodzera dzekuvharwa nekuchengetwa kwakakosha kuti membrane irambe iripo kwenguva refu.

Paunenge uchivhara sisitimu kwenguva pfupi (isingasviki vhiki), sukurudza membrane nemvura yechigadzirwa kuti ubvise chero tsvina yasara, wobva wachengeta membrane yakanyorova kudzivirira kuoma—kuomesa kunogona kukonzera kukuvara kusingagadzirisiki kune chimiro chemembrane chine maburi. Kuti uvhare kwenguva refu (inopfuura vhiki), shandisa mushonga unochengetedza (wakadai se sodium bisulfite solution) kuti unyike membrane. Iva nechokwadi chekuti huwandu hwekuchengetedza hwakakodzera uye tsiva mushonga nguva nenguva kudzivirira kukura kwebhakitiriya. Usati watangazve sisitimu, sukurudza membrane nemvura yakachena kuti ubvise mushonga unochengetedza, uchive nechokwadi chekuti mvura yechigadzirwa inosangana nezvinodiwa zvemhando yepamusoro.

Mhedziso

Kuwedzera hupenyu hwema RO membranes uye kuderedza mari yekushanda harisi basa rakaoma—zvinoda kushandiswa nguva dzose kwekugadzirisa kwakakodzera, kudzora zvakanyanya mashandiro, kuchenesa nguva dzose, kutarisa hunhu hwemvura nguva dzose, uye maitiro ekudzima nekuchengetedza akakodzera. Nekutevera mazano mashanu aya, haugone kungowedzera hupenyu hwebasa rema RO membranes, kuderedza kuwanda kwekuchinja kunodhura, asiwo kuvandudza kushanda kwese kweRO system, kuderedza simba nemitengo yekugadzirisa. Kuisa nguva nesimba mumatanho aya ekudzivirira kuchaunza mabhenefiti ehupfumi kwenguva refu uye kuona kushanda kwakasimba uye kwakavimbika kwesystem yako yekurapa mvura.
