PH Control Mfundo Mumagawo Osiyanasiyana a Reverse Osmosis Operation

Tekinoloje ya Reverse Osmosis (RO) yakhala mwala wapangodya pamakina amakono oyeretsera madzi, omwe amagwiritsidwa ntchito kwambiri m'mafakitale, ma municipalities, ndi malonda. Chimodzi mwazinthu zofunika kwambiri pakusunga magwiridwe antchito komanso kuteteza ma membrane a RO ndi pH control. Kuwongolera bwino kwa pH pamagawo osiyanasiyana a ntchito ya RO - kuperekera mankhwala, kachitidwe kachitidwe, ndi kuyeretsa - kumakhudza mwachindunji magwiridwe antchito, mtundu wamadzi, ndi moyo wa membrane.

Kufunika kwa pH mu RO Systems

Ma membrane a RO amakhudzidwa kwambiri ndi ma pH apamwamba. Ngakhale kuti polyamide thin-film composite (TFC) nembanemba imatha kugwira ntchito mkati mwa pH ya 4-11, njira zoyeretsera kwakanthawi kochepa zimalola kuwonetseredwa kumitundu yotakata (nthawi zambiri pH 2-12). Ngati pH siyikuyendetsedwa bwino, makulitsidwe, kuyipitsa, kapena hydrolysis ya nembanemba imatha kuchitika, kuchepetsa kukana mchere ndikufupikitsa moyo wautumiki.

Kuwongolera kwa pH m'magawo osiyanasiyana

1. Pretreatment Stage

• Cholinga: Pewani kukulitsa ndi kuyipitsa mkati mwa RO system.
• Njira: Sinthani pH ya madzi odyetsa kuti muchepetse ziwopsezo za mvula kuchokera ku ma ayoni olimba monga calcium carbonate, calcium sulfate, kapena silica. Mwachitsanzo, acid dosing (sulfuric kapena hydrochloric acid) nthawi zambiri amagwiritsidwa ntchito kutsitsa pH, motero mchere umasungunuka ndikuchepetsa makulitsidwe.

2. Gawo la Ntchito

• Cholinga: Pitilizani kuchita bwino pakuchotsa mchere ndikuteteza nembanemba.
• Njira: Panthawi yogwira ntchito, madzi odyetsa pH amasungidwa mokhazikika mkati mwazovomerezeka za wopanga nembanemba. Kukhazikika kumatsimikizira kuti gawo logwira ntchito la polyamide limasunga umphumphu wake, kukwaniritsa kukanidwa kwa mchere wambiri komanso kusasinthasintha kwamadzi.

3. Malo Oyeretsera (CIP - Clean-In-Ploce)

• Cholinga: Chotsani sikelo yochuluka, kuwonongeka kwachilengedwe, kapena kukula kwachilengedwe.
• Njira:
• Njira zoyeretsera asidi (otsika pH, pafupifupi 2-4) sungunulani makulitsidwe achilengedwe monga calcium carbonate kapena ma depositi achitsulo.
• Njira zoyeretsera zamchere (okwera pH, pafupifupi 10-12) chotsani zonyansa, mafuta, ndi zinthu zachilengedwe.
  Kusinthana pakati pa acidic ndi alkaline kuyeretsa kumatsimikizira kuchira kwathunthu popanda kuwononga nembanemba.

HID MEMBRANE CO., LTD.: Kupanga Mayankho a RO Membrane

Malingaliro a kampani HID MEMBRANE CO., LTD. ndi katswiri wopanga ma nembanemba apamwamba a RO, odzipereka kuti apereke njira zodalirika zochotsera mchere, kuthira madzi m'mafakitale, komanso kuyeretsa malonda. Mamembala a kampaniyo amapangidwa ndiukadaulo waukadaulo wa polyamide woonda-filimu, wopereka:

• Wide pH Kulekerera kuyeretsa ndi kukonza bwino.
• Kukana Mchere Kwambiri kuonetsetsa kuti madzi ali abwino.
• Chokhalitsa Magwiridwe ngakhale pansi pa zovuta za chemistry yamadzi.

Poyang'ana kwambiri zaukadaulo ndi mtundu, HID MEMBRANE imapereka chithandizo chaukadaulo chogwirizana, kuphatikiza chitsogozo cha njira zabwino zowongolera pH kuti apititse patsogolo magwiridwe antchito adongosolo ndikuwonjezera moyo wautumiki wa membrane.

Mapeto

Kuwongolera pH ndikofunikira pagawo lililonse la reverse osmosis. Kuchokera pakuletsa kuchulukitsitsa pakuwongolera, kuwonetsetsa kuti magwiridwe antchito akhazikika, mpaka kuyeretsa bwino kwamankhwala, kusunga pH yoyenera kumateteza mtundu wamadzi komanso moyo wautali wa nembanemba za RO. Malingaliro a kampani HID MEMBRANE CO., LTD. ikupitilizabe kuthandizira mafakitale padziko lonse lapansi ndiukadaulo wapamwamba wa membrane komanso chidziwitso chaukadaulo, kuthandiza makasitomala kupeza mayankho okhazikika komanso otsika mtengo opangira madzi.
