He aha i ngaro ai te mahi a ngā kiriuhi RO ahumahi – me pēhea te pupuri kia roa ake te ora

Ngā Kaihara Matua: He aha i Heke ai te Mahi

Kei te whakaekea tonutia ngā kiriuhi RO ahumahi e ngā poke wai whāngai. Ko te hekenga o te rere noa me te whakakorenga tote e ahu mai ana i ētahi tikanga ā-tinana me te matū.

Te Whakakino Colloidal me te OrganicKoinei pea te ānini tino kitea. Ka kohikohi ngā matūriki iri me ngā mea rauropi tūturu ki te mata o te kiriuhi, ka hanga he paparanga keke e aukati ana i te rere o te wai. E whakaatu ana ngā rangahau mō ngā wai para matū waro, he whāngai e tino werohia ana, ko ngā poke rauropi—ina koa ko ngā wāhanga hydrophobic me ngā mea rauropi fluorescent—ko rātou ngā tino take o te hekenga o te rere. Ina piri ēnei mea rauropi ki te mata polyamide, ka hangaia he turanga piri mō te poke atu anō.

Te Tauine me te Paraipara Kore-ParaoaKa puta tēnei ina nui ake ngā tote wairewa iti i ō rātou rohe wairewa i roto i te awa kukū. He maha ngā wā ka pāngia e te konupūmā kāponāte me te konupūmā whanariki, engari kei te piki haere te mōhiotia o te poke o te silicon hei tūmomo mōrearea nui i roto i te hangarua wai para ahumahi. Ka taea e te whakapūhui silica i runga i te mata o te membrane te arahi ki te ngaronga o te rerenga kore e taea te hoki, ā, he mea matua tēnei i roto i ngā membrane e tae atu ana ki te mutunga o te oranga. He tino raruraru tēnei i roto i ngā pūnaha whakaora-teitei ina ka nui haere te silica.

Te Whakahekenga Matū me te Waikuraka whakaekea te paparanga polyamide whiriwhiri o te membrane. Ko te chlorine, e whakamahia ana i roto i te patu huakita i runga ake, he matū whakahāwea kaha e taea ai te tapahi i ngā hononga amide, ka whakangaro tonu i ngā kaha whakakore tote. Ko te ture matua o te umanga—te pupuri i te chlorine kore utu i raro i te 0.1 ppm—kei te noho mō tēnei take tonu.

Te Ine i te Pānga: Te Utu Nui o te Parahanga

He nui te pānga ōhanga o te paru. E ai ki ngā tātaritanga, tata ki te 24% o ngā utu whakahaere i roto i ngā pūnaha RO te paru o te kiriuhi. Ka kitea tēnei mā te pikinga o te whakapaunga pūngao (te pēhanga whāngai teitei ake hei pupuri i te rere), te horoinga matū auau ake (e whakaiti ana hoki i te kiriuhi), ā, i te mutunga, te whakakapinga wawe.

E whakaatu ana tētahi rangahau i te tau 2025 mō te maimoatanga hiko-matū mō te RO i te nui o te tūponotanga: kua roa ake te roa o te ora o ngā kiriuhi e rongoā ana i te wai whakamatao ahumahi uaua.203%i te wā i whakamahia ai te maimoatanga i mua i te whakamahinga whai hua, ka whakaitihia ngā utu whakahaere mā te 80%. E whakaatu ana tēnei ehara te mahi a te membrane i te mahi a te membrane tonu, engari ko te hoahoa katoa o te pūnaha.

Te Whakaroa i te Ora o te Ratonga: He Rautaki Maha-Waenga

Ko te whakaroa i te ora o te membrane me whai rautaki whānui e tīmata ana i mua noa atu i te taenga atu o te wai ki te huānga membrane.

1. Te Maimoatanga Arotau: Tō Raina Parenga Tuatahi

E ai ki ngā raraunga ahumahi, tae atu ki te 80% o ngā pakaru o te kiriuhi wawe i ahu mai i te koretake o te maimoatanga i mua. Kāore e taea te whiriwhiri i te maimoatanga whai hua.

• Ngā Whakangawari me ngā Ārai-Pango:Mā te tango i ngā katote mārō (Ca²⁺, Mg²⁺) mā te whakawhiti katote, mā te whakangawari matū rānei, ka tino whakaitihia te kaha o te tauine. I kitea i roto i tētahi rangahau, e 79% o te konupūmā mai i te wai para waro i tangohia e te whakangawari, ā, ka ārai i te hanganga o ngā matū kore-ora e whakapoke ana i ngā kiriuhi.
• Te mimiti me te waikura:Ka tangohia e te waro whakahohe kirikiri (GAC) te chlorine kore utu, ā, ka mimiti i ngā poke waro. Ka taea e te ozonation te wawahi i ngā waro taumaha-ngota teitei, ka iti ake te tūponotanga ka piri ki te mata o te membrane. I ētahi wā, kua whakaatuhia e ēnei maimoatanga o mua ka whakanui ake i te rere o te membrane kua whakatauritea ki te 21.9%.
• Mana Whakahaere SDI:He mea nui te pupuri i te Taupū Matotoru Para (SDI) i raro i te 3 (kaua rawa e neke ake i te 5). Mā te tātari iti, te tātari nui rānei i te awa whakarunga ka tutuki ai tēnei whāinga.

2. Mahi Atamai: Te Whakataurite i te Mahi me te Pumau

Me āta whakahaere ngā āhuatanga whakahaere:

• Ārai i te pēhanga nui rawa:Mā te nui rawa o te pehanga kua whakatauria o te membrane ka pēhia te hanganga o te membrane (ka pēhia), ka whakaitihia te uruhanga e kore e taea te hoki whakamuri.
• Whakahaerehia te Auau Whakaora:Mā te akiaki i te whakaora wai kia nui ake ka piki ake te kukū o ngā katote tauine i roto i te wai tote. He mea nui te whakataurite i te whakaputanga wai me te mōrearea tauine.
• Kia mau tonu ngā āhuatanga pumau:Ka puta te ahotea ā-pūkaha me te ahotea matū nā ngā piki me ngā heke o te pH, te pāmahana, me te rere. Ka tino pai te mahi a te paparanga polyamide i roto i te awhe pH pumau o te 6-8.

Whakamutunga

Ehara i te mea e kore e taea te karo i te hekenga o te mahi membrane; he hua ia o ngā taunekeneke ā-tinana me te matū e taea te matapae. Ko te ara ki te roa o te ora ratonga kei roto i te whakaae ki ngā "hononga ngoikore"—mai i te whakapūhui silica ki te piri waro—me te whakatika i aua mea mā te whakahaere pūnaha atamai me te hoahoa membrane matatau. Mā te whakakotahi i te maimoatanga pakari, ngā tikanga whakahaere tupato, me tā mātou hangarau membrane iti-paru, ka taea e ngā kaiwhakahaere ahumahi te wawahi i te huringa o te whakakapinga auau me te whakatutuki i te mahi pono, utu-whai hua mō ngā tau.
