Ko reverse osmosis membrane fouling inokonzerwa sei? Nzira yekuigadzirisa sei?

Membrane fouling idambudziko rakakura rine mhedzisiro yakaipa pakuita kwayo. Inoderedza kurambwa uye kuyerera kwehuwandu, zvichikonzera kushandiswa kwesimba kwepamusoro uye kuderera kwemvura inobuda.

Ko reverse osmosis membrane fouling inokonzerwa sei?

1. Kuchinja kunowanzo muhutano hwemvura yakasvibirira: Nekuda kwekuwedzera kwehutsvina hwakadai seinorganic matter, organic matter, microorganisms, particulate matter, uye colloids mumvura mbishi, membrane foiling inogona kuitika kakawanda.

2. Panguva yekushanda RO system, kuchenesa kusingatarisirwi uye nzira dzisina kururama dzekuchenesa zvakare zvinhu zvinokosha zvinotungamirira ku membrane fouling

3. Kuwedzera zvisina kunaka chlorine nezvimwe zvinouraya utachiona panguva yekushanda RO system, pamwe chete nekutarisa kusina kukwana kunobhadharwa nevashandisi kukudzivirira kwehutachiona, zvinogona kutungamirira nyore kusvibiswa kwehutachiona.

4. Kana iyo RO membrane element yakavharwa nezvinhu zvekunze kana kuti membrane yakapfekwa (yakadai sejecha particles), nzira yekuona inofanira kushandiswa kuona zvinhu muhurongwa uye kutsiva membrane element.

Hsei kuderedza membrane kusvibiswa?

1.Vandudza pre-kurapa

Kune yega yega RO chirimwa, vanhu vanogara vaine tarisiro yekuwedzera kushanda kwayo, neiyo yakanyanya desalination yakanyanya kupenya kwemvura, uye hupenyu hwakareba kwazvo. Naizvozvo, kunaka kwemvura kwakakosha. Mvura yakasvibirira inopinda muRO chirimwa inofanirwa kuve neyakanaka pre-kurapwa. Reverse osmosis pre-treatment inotarisirwa: (1) Kudzivirira kusvibiswa pamusoro pemembrane surface, kureva, kudzivirira kusvibiswa kwakamiswa, microorganisms, colloidal substances, nezvimwewo kubva pakunamatira kune membrane pamusoro kana kuvhara nzira yekuyerera kwemvura ye membrane elements. (2) Dzivirira kuyera pane membrane pamusoro. (3) Dzivirira membrane element kubva kumakanika uye kukuvara kwemakemikari kuve nechokwadi chekuita kwakanaka uye hupenyu hwesevhisi hwakakwana.

2 . Chenesa membrane element

Pasinei nematanho akasiyana-siyana ekutanga kurapwa akatorwa kumvura yakasvibira, sedimentation uye scaling inogona kuramba ichiitika pamusoro pe membrane mushure mekushandiswa kwenguva refu, zvichikonzera kuvhara kwe membrane pores uye kuderera kwekugadzirwa kwemvura yakachena. Naizvozvo, zvinodikanwa kugara uchichenesa membrane element.

3 . Chenjerera kushanda panguva yekudzima ROsystem

Paunenge uchigadzirira kuvhara RO chirimwa, kuwedzera kemikari reagents kunogona kuita kuti mareagents arambe ari mu membrane uye imba, zvichikonzera membrane kusvibisa uye kukanganisa hupenyu hwebasa re membrane. Dosing inofanira kumiswa kana uchigadzirira kuvhara RO chirimwa.
