Me pēhea te whiriwhiri i te kiriuhi RO ahumahi tika mō te wai whāngai TDS teitei
He aha i kore ai e angitu ngā kiriuhi RO paerewa i roto i ngā tono TDS teitei
Ko ngā kiriuhi RO wai parakore paerewa he mea hanga mō ngā āhuatanga wai ā-tāone, ā-mata rānei, i raro i te 5,000 ppm TDS. Ina pāngia ki te tote teitei ake, ka tere ake te pakaru o ētahi tikanga:
- Te taumaha rawa o te pēhanga osmotic
Ko te TDS teitei ake he tikanga he nui ake te pēhanga osmotic. Ka mahi ngā kiriuhi paerewa i ngā paepae pēhanga kua whakaritea; ina hipa atu, ka heke tere te rere o te wai, ā, me utu e te pūnaha mā te pēhanga papu teitei ake, ka piki ake te whakapaunga pūngao me te ahotea miihini ki ngā huānga me ngā oko pēhanga. - Te whakaterenga kukū tere
I te mata o te kiriuhi, ka hangaia e ngā tote i whakakahoretia he paparanga rohe kukū. I roto i te wai whāngai TDS teitei, ka tere ake te matotoru o tēnei paparanga, ka whakaiti i te kaha pana whai hua, ka whakaiti i ngā reiti whakakahore o te ao tūturu, ā, ka hanga i ngā āhuatanga mō te tere o te noho o te unahi me te paru. - Te āhua o te tauine me te poke
Ka tere ake te kukū o te konupūmā whanariki, te silica, me ngā tote wairewa iti i roto i ngā awa tote nui. Kāore i roto i ngā kiriuhi paerewa me te matū mata paerewa ngā whakarerekētanga ārai-paru e hiahiatia ana hei ārai i te whakatakotoranga kohuke me te tipu biofilm i raro i ngā āhuatanga kukū. - Te ngoikore o te mahi whakakorenga mō te wā roa
Ka āta whakakīkī haere te paparanga polyamide o ngā kiriuhi paerewa i te roanga tonu o te pānga ki te tote nui, ka ngaro tonu te kaha ki te whakakore tote, ā, ka whakakapia wawetia ngā huānga i te wā e tika ana.
Ko te hua: he nui ake te horoinga, he nui ake ngā pire hiko, he koretake te kounga o te whakaurunga o te hau, me te tapeke o te utu whakahaere e nui atu ana i ngā matapae tuatahi.
Te Whakataurite i te Kōwhiringa Membrane ki ngā Taumata TDS o te Wai Whāngai
Ko te tawhā kotahi tino nui mō te whiriwhiri i te kiriuhi ko te TDS o te wai whāngai. Kei raro nei he anga mahi mō te whiriwhiri i waenga i ngā kiriuhi wai māori me ngā kiriuhi tango tote wai moana.
- Ngā kiriuhi wai parakore: 1,000 – 10,000 ppm TDS
Ko ngā kiriuhi RO wai parakore (BWRO) he mea arotau mō ngā puna tote āhua rite tonu ki te wai puna hohonu, te wai whenua, me te wai mata he nui te ihirangi kohuke.
Tino pai mō:
- Ngā puna ahumahi o uta me te wai poka wai
- Wai tukatuka keri me te wai whakaputa me te tote taurite
- Kai me te inu, whāngai pūwero, me te maimoatanga wai ā-tāone
- Ngā pūnaha e whai ana i te 75–85% o te whakaoranga i te pēhanga whakahaere taurite
Ngā paearu whiriwhiri matua:
- Te tere whakakorenga teitei mō ngā tote noa (NaCl, MgSO₄, Ca²⁺)
- Te matū mata ātete-paru mō te kounga whāngai rerekē
- Te taurite o te rere me te pēhanga hei whakaiti i te kawenga papu
Mō te wai whāngai kei runga ake i te 5,000 ppm TDS, tērā pea kua tata kē ngā huānga BW paerewa ki tō rātou taumata. I ēnei wā, he pai ake te pumau mō te wā roa me te utu iti mō te huringa ora nā te wai parakore whakakorenga-teitei, nā te kiriuhi wai moana iti-pūngao rānei.
- Ngā Kiriuhi Whakakore i te Tote o te Wai Moana: 15,000 – 45,000 ppm TDS
He mea hanga ngā kiriuhi RO wai moana (SWRO) ki tētahi paparanga polyamide kiato ake, me te hanganga whakakaha hei tu atu i te pēhanga osmotic teitei o ngā awa wai moana me te wai tote.
Tino pai mō:
- Ngā tipu tango tote i te wai moana i te takutai moana
- Ngā papaaho taiwhenua me ngā kaipuke moana
- Ngā wāhanga kukū tote kore tukunga wai (ZLD)
- Te wai i whakaputaina he TDS teitei i roto i te hinu me te hau me te maina
Ngā paearu whiriwhiri matua:
- Kua whakamātauhia te tango i te TDS teitei me te whakakorenga tote pumau i raro i te mahi tote-teitei tonu
- Te pakari ā-mīhini mō ngā pēhanga mahi teitei (600–1,200 psi)
- Hototahi ki ngā taputapu whakaora pūngao mō te whakaiti i te whakapaunga pūngao motuhake
Ko tētahi whakaaro hē noa ko te whakaaro ko ngā kiriuhi SWRO he mea hanga noa mō te wai moana. Mō ngā tono wai parakore TDS teitei i te 10,000 ppm, neke atu rānei, ka taea e te huānga wai moana e whakahaerehia ana i te pēhanga reo te whakaputa i te panga pai rawa atu me te roa ake o te ora me te rere e whakaaetia ana.
Ngā Otinga Membrane Whakaora-Tiketike, Pūngao-Iti mō ngā Pūnaha TDS-Tiketike Tino Tonu
Kua hangaia te whakatupuranga hou o ngā kiriuhi RO motuhake hei whakaoti i te taupatupatu matarohia i waenga i te whakakorenga teitei, te whakaora teitei, me te whai huatanga o te pūngao. I te aromatawai i ngā raupapa kiriuhi mō te ratonga TDS teitei, me whakarite kia toru ngā āhuatanga hoahoa:
- Matū Polyamide Matatau mō te Whakakorenga Teitei Pūmau
Ko ngā kiriuhi ahumahi taumata teitei he paparanga hohe polyamide honohono-whiti, he tino honohono e pupuri ana i te whakakorenga NaCl pumau ahakoa i raro i te TDS rerekē me ngā huringa pāmahana. Rapua ngā kiriuhi kua whakatauria mō te ≥99.7% whakakorenga NaCl i roto i ngā āhuatanga whakamātautau paerewa—ka roa ake te pupuri i tā rātou mahi i roto i te ratonga tote teitei o te ao tūturu.
- Hanganga Kiriuhi Arotau mō te Whakaora Ake
Kei roto i ngā huānga kiriuhi whakaora-teitei ngā mokowā whāngai whānui me te āhua rau kua whakarerekētia hei whakaiti i te porotiti kukū me te hekenga pēhanga. Mā tēnei ka taea e ngā pūnaha te whakahaere i ngā tere whakaora teitei ake (85%+ mō te wai māori, 45–55% mō te wai moana kotahi-haerenga) me te kore e nui te mōrearea o te tauine, ka whakaiti i te rahinga tukunga tote me te whakaiti i te utu wai katoa.
- Ngā Kōtaha Pūngao-Iti, Rere-Tiketike
Ka tukuna e ngā kiriuhi mahi-teitei o ēnei rā te whakakorenga tote ōrite, pai ake rānei i te pēhanga mahi iti iho i ngā hua tawhito. Ina honoa ki ngā taputapu whakaora pūngao i roto i ngā pūnaha SWRO, ka taea e rātou te whakaiti i te whakapaunga pūngao motuhake—ka whakaiti tika i te OPEX mō ngā whare e whakahaere ana i te 24/7.
Mō ngā kaiwhakamahi mutunga, me whakauru ngā hua tika ki roto i te kohinga:
- Raupapa wai parakore tino-whakakore mō te 2,000–10,000 ppm TDS me ngā mata ātete-paru
- Raupapa tango tote wai moana mō te 15,000–45,000 ppm TDS me te pumau roa-papa kua whakamātauhia
- Ngā kiriuhi kukū tote motuhake mō ngā tereina ZLD me MBR-RO e whakahaere ana i ngā TDS tino kino
Whakamutunga
Ka pāngia ngā kiriuhi RO kāore i te pai te mahi a te wai whāngai TDS teitei e te ngoikore o te mahi, te nui o te whakamahinga pūngao, me te poto o te ora mahi. Ko te otinga ehara i te whakahaere kaha i ngā kiriuhi paerewa—engari ko te whiriwhiri i ngā kiriuhi i hangaia mō te taumata tote o tō wai pūtake.
Tīmata mā te tautuhi tika i te TDS me te hanganga o tō wai whāngai, kātahi ka whakataurite ki te whānau kiriuhi wai māori, wai moana rānei e tika ana. Mō te uara huringa ora mōrahi, whakaritea ngā huānga kua hangaia kia teitei te panga, kia ātete ki te paru, kia pai ai te whai hua o te pūngao—tērā pea he iti noa te utu i mua, engari ka penapena i te pūngao, ngā matū, te wā horoi, me te auau whakakapinga.
Mena kei te arotake koe i tētahi whakapai ake mō tō pūnaha maimoatanga wai TDS-teitei, kei te hoahoa rānei i tētahi tipu hou mō te tango tote i te wai māori, i te wai moana rānei, mā te mahi tahi me tētahi kaiwhakarato kiriuhi e tuku ana i ngā raina hua motuhake ki te tono me te tautoko hangarau ka āwhina i a koe ki te whakatutuki i ō whāinga kounga wai, whakaora, me te utu mai i te rā tuatahi.
