Reverse osmosis (RO) mvura kusefa masisitimu isarudzo yakakurumbira yekugadzira mvura yakachena, yakachena. Chinhu chakakosha muRO masisitimu ndeye semipermeable membrane inobvisa zvinosvibisa. Nekufamba kwenguva, RO membrane performance inoderera uye kutsiva kunodiwa. Muchikamu chino, ini ndichakurukura zvinhu zvinokanganisa hupenyu hwe membrane uye maitiro akanakisa ekutsiva RO membrane.

Mhedziso yeRO Membrane Basa

RO masisitimu anoshandisa multi-stage filtration process kuti abvise zvimedu, makemikari, ma microorganisms uye kumwe kusvibiswa kubva mumvura. Iyo RO membrane ndiyo moyo wehurongwa. Ifirimu rakatetepa rinosanganiswa ne microscopic pores inovhara nzira yemunyu wakanyunguduka uye zvimwe zvinosvibisa.

Sezvo mvura ichipfuura nepakati RO membrane pakumanikidzwa kukuru, mamorekuru emvura akachena anoyerera nepo tsvina zhinji ichichengetwa uye kugezwa pasi pemvura. Nokufamba kwenguva, kusvibiswa kwekuvaka pane membrane pamusoro kunotungamirira kukusvibisa uye kurasikirwa kwekushanda.

Yakajairika RO Membrane Hupenyu

Hupenyu hwe membrane yeRO zvinoenderana nemhando dzakasiyana. Nemamiriro akakwana, hupenyu hwe membrane hunowanzo makore 2-5 kune masisitimu ekugara uye 5-7 makore ekushandisa kwakareruka kwekutengesa. Nekudaro, husina kunaka hwemvura uye kugadzirisa kunogona kupfupisa hupenyu hwe membrane zvakanyanya.

Paavhareji, ronga kutsiva iyo RO membrane makore ega ega matatu mukuisa kwakawanda kwemba. Kushandiswa kwepamusoro uye kunetsa mamiriro emvura anogona kuraira kakawanda kutsiva membrane makore ese 3-1.

Zvinhu Zvinokanganisa Kureba KweMembrane

Pane zvakati wandei zvakakosha zvinokanganisa kuti RO membrane ichagara kwenguva yakareba sei isati yada kutsiviwa:

• Hunhu hwemvura - Yakakwira nhanho uye mamwe makemikari mumvura yekudyisa anogona kusvibisa membrane nekukurumidza. Mvura yemutsime inonyanya kunetsa.

• Kushandiswa kwemvura - Kushandiswa kwakanyanya uye kukwira kwevhoriyamu kunopfeka membrane kubuda nekukurumidza.

• Maintenance - Kushaikwa kwekucheneswa kwakakodzera membrane uye sefa shanduko inopfupisa hupenyu hwe membrane.

• Dzvinyiriro - Kushanda pasi pepasi kana kudzvanywa kwakanyanya kunosimbisa membrane.

• Zera - Membranes zvishoma nezvishoma anorasikirwa nekuita sezvaanokura.

Tembiricha yemvura inoitawo basa. Mvura inodziya inoguma nekukurumidza kuyerera asi inogona kupfupisa nguva yekumhanya. Mvura inotonhora inochengetedza membrane asi inononoka kugadzirwa.

Zviratidzo Yasvika Nguva Yekuchinja Membrane

Nzira yakavimbika yekuziva membrane yakasakara ndeyekuderedzwa kwepermeate kuyerera. Sezvo membrane inosvibiswa uye mapaipi anotanga kukwira, huwandu hwemvura yakasefa inogadzirwa inodonha.

Zvimwe zviratidzo kuti yave nguva ye membrane nyowani:

• Kuderera kwekuramba mitengo - Zvimwe zvinosvibisa zvinopfuura nehurongwa.

• Yakakwira TDS - Yakasimudzwa yakazara yakanyungudika yakaoma mumvura yechigadzirwa.

• pH inoshanduka - Shanduko mumvura inoyerera pH.

• Kunhuwa/kuravira - Kunhuwa kana kuravira kunoratidza kusvibiswa.

• Kutadza kudzoreredza - Kusakwanisa kuwedzera kumashure anobatsira zvicherwa.

• Leakage - Mvura inopfuura nepa membrane brine seal.

• Kuchembera - Kuita kuderera mushure memakore 3-5.

Kuitisa gore negore membrane autopsies uye yenguva dzose kugadzirwa kuyerera kuyedzwa kunoita kuti uone matambudziko nekukurumidza.

Maitiro Akanakisa e RO Membrane Replacement

Kana yave nguva yekutsiva RO membrane, ita shuwa yekutevera maprotocol akakodzera:

• Ongorora mamwe ese mafirita uye wotsiva sezvinodiwa

• Flush mavharuvhu, tubing uye dzimba zvakakwana

• Shandisa magirovhosi ekudzivirira uye kupfeka kwemaziso

• Tevera mirairo yemugadziri

• Disinfect system ne chlorine mushure mekuisa

• Simbisa kutariswa kwe membrane - miseve yakanyorwa

• Lubricate o-mhete uye brine chisimbiso

• Re-pressurize uye tarisa kuti pane inobuda

• Bvisa membrane nyowani maererano negwara

• Test permeate mvura yemhando

Kutsiva pre-mafirita uye kuchenesa yekare mineral scale inobatsira kuwedzera hupenyu uye kuita kweiyo membrane nyowani. Tora nguva yekuchenesa zvizere sisitimu zvakare.

Kuvandudza Membrane Hurefu

Iwe unogona kukwenenzvera hupenyu hwe membrane kuburikidza neyakakodzera sisitimu dhizaini, kugadzirisa, uye kushanda mamiriro:

• Pretreatment - Multi-stage prefiltration inowedzera hupenyu hwe membrane.

• Flushing - Gara uchikwesha ma membranes ne permeate.

• DIY Kuchenesa - Dzimwe nguva kudzika kwakadzika neDIY kits.

• pH kugadzirisa - Chengetedza mvura yekudyisa pH pakati pe3-11.

• Leak macheki - Gadzirisa chero mavuza nekukasira kudzivirira kurasikirwa kwemvura yakawandisa.

• Kushandisa - Dzivisa kuyerera kwakanyanya uye nguva refu yekumira.

• Dzvinyiriro - Chengetedza kumanikidzwa pakati pe50-125 psi.

• Tembiricha - Ambient tembiricha yakatenderedza 77°F ndiyo yakanaka.

• Yakarongwa kutsiva - Shandura membrane pane hurongwa zvisinei nemamiriro anoonekwa.

Yakakodzera RO membrane kuchengetedza inoguma mune inowirirana system kuita uye yakavimbika mvura yakachena. Kudzivisa kukanganisa nguva isati yakwana uye kukundikana kunochengetedza mari munguva refu zvakare.

Final Thoughts

RO membrane kutsiva chikamu chisingadzivisiki chekuve neRO system. Neavhareji yekushandiswa kwekugara, ronga kutsiva membrane makore ese matatu. Mvura yakaoma yakawanda kana kushandiswa kwakanyanya kunogona kuraira kuchinja kunowanzoitika makore 3-1 ega ega.

Tarisa huwandu hwekugadzirwa kwesystem yako uye pinda mumhando yemvura. Paunoona kuderedzwa kuita, inguva chaiyo ye membrane nyowani. Nekugadzirisa kwakakodzera uye mamiriro ekushanda, unogona kukwidziridza RO membrane hupenyu. Asi hapana membrane inogara nekusingaperi, saka kutsiva nguva nenguva kwakakosha.
