Waizviziva Here? Kuchengetedza Yako RO Membranes Panguva Yekuvhara Kwakakosha!

Kana reverse osmosis (RO) masisitimu ari kushingaira kuchenesa mvura, isu tinonyatso tarisa kudzvanywa, kuyerera, uye kunaka. Asi chii chinoitika kana midziyo yamira? Zvinoshamisa kuti nguva iyi yekusaita basa inoisa njodzi dzakavanzika kune dzakatetepa RO membranes, izvo zvinogona kukonzera kukuvara kusingadzoke uye kupfupisa hupenyu hwavo. Kunzwisisa njodzi idzi uye kuita nzira dzekuvhara dzakafanira kwakakosha.

Kuvhara Kunokuvadza sei RO Membranes:

Biological Growth (Biofouling): Mvura yakamira mukati memidziyo yekumanikidza inova nzvimbo yekuberekera hutachiona senge bhakitiriya nefungi. Izvi zvipenyu zvinokurumidza kuwanda, zvichiita zvinonamira biofilms zvakananga pamusoro pe membrane. Iyi biofilm inoderedza zvakanyanya kuyerera (kubuda kwemvura) uye inowedzera munyu ndima, inosvibisa kuita zvachose kunyangwe mushure mekuchenesa.

Scale Formation: Zvicherwa zvakanyungudutswa senge calcium carbonate, sulfates, kana silica, yakatarisana ne membrane pamusoro panguva yekushanda, inogona kupenya nekuomesa pa membrane panguva yekudzima. Uku kuyera kunoderedza zvakanyanya kubereka uye kazhinji kunonetsa kubvisa zvachose.

Dehydration uye "Creep": Membranes akagadzirirwa kushanda pasi pekumanikidzwa. Panguva yekuvhara kwakawedzera pasina kunyorova, iyo semi-permeable layers inogona kuoma zvishoma. Zvakatonyanya, pasina kumanikidzwa kwemukati kubata chimiro chazvo, dense membrane zvinhu zvakarongedzerwa mukati mezvitsiga zvekumanikidza zvinogona kuremara mumuviri ("zvinokambaira"). Iyi deformation inokuvadza yakaomesesa kuyerera nzira uye chimiro chemidziyo, zvichitungamira mukurasikirwa kwekuita kwechigarire uye kunogona kudonha.

Kemikari Degradation (Zvinogona): Kana makemikari asingaenderane ekuchengetedza akadzikira nekufamba kwenguva kana kunyungudutswa zvisina kunaka asati atangazve, anogona kurwisa membrane polymer pachayo. Tsvina inopinda muhurongwa husina kuvharwa panguva yekudonha inogonawo kuunza njodzi yemakemikari.

Solutions: Kudzivirira Membranes Panguva Kuvhara

Chinokosha ndechekuchengetedza kuchengetedza, kunoenderana nenguva yekuvhara:

Kuvhara Kwenguva Pfupi (

Flush: Ita yakanyatsorongeka, yakaderera-kudzvanywa mvura ine RO chigadzirwa mvura (kana yakachena permeate) kudzinga yakadzika yemvura yekudyisa kubva mu membrane pamusoro pakarepo mushure mekumisa kuyerera kwekudya.

Chengetedza Kunyorova: Chengetedza membrane zvinhu zvakanyura zvachose uye system yakavharwa kudzivirira kupera mvura. Dzokorora kana kuchenesa maawa ega ega 24-48 kana zvichibvira.

Kuvhara Kwenguva Yakareba (>72 Maawa) kana Kuchengeta:

Kunyatsocheneswa: Ita kutenderera kwakazara kwekuchenesa usati wavhara kuti ubvise foulants uye chiyero precursors.

Preservation Solution: Flush iyo yese system, kusanganisira yekumanikidza midziyo uye zvinhu, ine yakakodzera kuchengetedza mhinduro:

Sodium Bisulfite (Common & Preferred): Mushonga we1% unoshandiswa zvakanyanya kudzora kukura kwehutachiona kuburikidza nekutsvaira kweokisijeni. Inoda nguva nenguva kuyedzwa uye kuzadzazve / kutsiviwa.

Chikafu-Giredhi Glycerin: Kazhinji inoshandiswa kune yakaoma kuchengetedza. Membranes inofanira kuzara ne 15-20% glycerin solution uye inobvumirwa kunyura zvakakwana isati yavharwa kuitira kuchengetedza kwenguva refu kudzivirira zvose kukura kwe microbial uye kupera simba. Ongorora: Vamwe vatengesi vanopa zano rakasimba pamusoro pekuchengetedza yakaoma nekuda kwenjodzi dzinokambaira.

Precise Concentration: Tevedzera nhungamiro yevagadziri yehuwandu chaihwo hwekuchengetedza kwakasarudzwa.

Tembiricha: Chengetedza pasi pe35°C (95°F) asi pamusoro pechando. Kuchengetedza kunotonhora (°C kana 50°F) inowedzera kunonoka kukura kwehutachiona.

Chisimbiso & Dzivirira: Ita shuwa kuti mazaruro ese akavharwa zvakasimba kudzivirira mhinduro kubuda uye kusvibiswa.

Kugara Kuongorora: Nguva nenguva tarisa pH uye kusungirirwa kwemhinduro yekuchengetedza, uchiitsiva mazuva ese makumi matatu kusvika makumi mapfumbamwe kana zvichidikanwa.

Dzivisa Backpressure: Nguva dzose sunungura kumanikidzwa kubva kudivi rekutarisa usati wadzima iyo yakakwirira-kudzvanywa pombi kudzivirira deformation.

Yakakosha Post-Shutdown:

Nyatsotsvaira: Usati watangazve, geza sisitimu zvakanyanya nemvura yechigadzirwa kana yakaderera-kudzvanya mvura yekudyisa kuti ubvise makemikari ese ekuchengetedza.

Zvishoma nezvishoma Kutanga: Re-pressurize iyo sisitimu zvishoma nezvishoma zvinoenderana nemugadziri specs.

Monitor Performance: Nyatsoteerera kune yakajairwa permeate kuyerera, kudonhedza kudonha, uye kurambwa kwemunyu mumaawa / mazuva mushure mekutangazve.

Mhedziso:

Usarega downtime ichiparadza mari yako! Kungodzima RO system pasina matanho ekuchengetedza akakodzera kunokoka biofouling, scaling, uye membrane deformation. - mhondi dzakanyarara dzinodzikisira kuita uye dzinokonzeresa kukundikana nguva isati yakwana. Nekunzwisisa njodzi idzi uye nekushingairira kuita nzira dzakakodzera dzekugezesa kana kuchengetedza zvichienderana nenguva yekuvhara uye kurudziro yemugadziri, unoita shuwa kuti ma membranes ako anoramba akadzivirirwa, anoita zvakaringana kwehupenyu hwawo hwekugadzira, uye kuendesa mvura yakachena yaunovimba nayo. Rangarira, kuedza kushoma panguva yekuvhara kunochengetedza mutengo wakakosha uye nguva yekudzikira gare gare.
