Me pēhea te whiriwhiri i te kiriuhi RO ā-whare

He mea nui te whiriwhiri i te kiriuhi Osmosis Whakamuri (RO) tika mō te whare kia ma ai te wai inu, kia iti ai hoki ngā utu mō te wā roa. Anei tētahi aratohu whānui hei āwhina i a koe ki te whakatau whai whakaaro.

🎯 1. Whakatakotoria ngā Inenga Mahi hei Kaupapa Matua

Koinei ngā tohu tino nui o te kounga me te whai huatanga o te membrane RO.

• Te Auau Whakakore Tote: Ka ine tēnei i te kaha o te kiriuhi ki te tango i ngā tote rewa, ngā konganuku taumaha, me ētahi atu poke. Ko te auau teitei ake he tikanga he wai parakore ake.
• Ko te tere tango tote o ngā kiriuhi kounga teitei he≥98%, ā, neke atu i te 99% ngā waitohu rongonui pērā i a HID.
• Ko ngā kiriuhi kounga iti ake pea kei raro iho i te 95% te reiti, kāore pea e ranea, inā koa i ngā wāhi he nui te Total Dissolved Solids (TDS) i roto i te wai puna.
• Putanga Wai Whakatauranga (Roanga Ora): E tohu ana tēnei i te nui katoa o te wai parakore ka taea e te kiriuhi te whakaputa i mua i te hiahia kia whakakapia. He tohu pono ake tēnei mō te roanga o te ora i te wā kua whakaarohia (hei tauira, "roanga ora 3-tau").
• Rapua he kiriuhi he iti rawa te putanga 4000-6000 rita. Ko te uara teitei ake he tohu he roa ake te ora me te pakari o te kiriuhi.
• Te Rere o te Wai (Rere): E pā ana tēnei ki te tere o te whakaputa wai parakore e te kiriuhi. Ahakoa he mea nui, kaua e whakanuia i te tere tango tote. Kia tūpato ki ngā kiriuhi e kī ana he tino teitei te rere o te wai engari me nui rawa te pēhanga hei whakatutuki, nā te mea he tohu pea tēnei o te kounga iti.

🔬 2. Arotakehia ngā Rauemi me ngā Hanganga

Ko ngā rauemi e whakamahia ana e whakatau ana i te roa, te haumaru, me te ātete o te membrane ki te poke.

• Rauemi Huānga Kiriuhi: Ko te paerewa ahumahi mō te whakamahinga kāinga mahi teitei ko te kiriuhi hiato polyamide kakara. Ka tukuna e ēnei he taurite pai o te tango tote nui, te tere rere pai, me te pakari. Āta karohia ngā rauemi tawhito, iti ake te utu rānei pērā i te cellulose acetate mō te tātari tuatahi.
• Ngā Rauemi mō te Ara Wai: He mea nui anō hoki ngā wāhanga o roto e haere ana te wai kua tātarihia. Hei whakarite i te haumaru me te ārai i te poke tuarua:
• He pai ake ngā pūnaha e whakamahi ana i ngā rauemi kore-BPA, he pai ake rānei, ko te maitai kore waikura 316 (ngā ara wai). Mā tēnei ka kore e pāngia te wai e ngā matū kino.
• Hoahoa Kore-Tāpiri: Ka tāpirihia e ētahi kaihanga ngā matū ārai-whakarewa (he matū hei ārai i te kohikohinga o ngā kohuke ki runga i te kiriuhi) hei whakaroa i tōna roanga. Mō te wai tino parakore, rapua ngā hua e hokohokohia ana ko "0 tāpiri" "0 ārai-whakarewa" rānei.

💰 3. Tātarihia ngā Utu mō te Wā Roa

Ko te utu hoko tuatahi he wāhanga noa iho o te whārite. Ko te utu tonu mō te tiaki te wāhi e takoto ana te whakapaunga tuturu.

• Tātaihia te Utu Whakakapinga Tātari ā-Tau: Kaua e titiro noa ki te utu o te kiriuhi RO. Me tātai e koe te utu ā-tau katoa mō te whakakapinga i ngā tātari katoa i roto i te pūnaha (tae atu ki ngā tātari-mua pērā i te miro PP me ngā poraka waro, te kiriuhi RO, me te tātari muri-waro).
• Tāpirihia te utu mō ngā tātari katoa e hiahiatia ana, ka wehea mā te roanga o te ora o ia tātari kia whiwhi ai i te utu ā-tau tūturu. Ko te whāinga pai ko te pupuri i te utu tātari ā-tau i raro i te 500 CNY.
• Rongonui me te Tiwhikete Waitohu: Ko te whiriwhiri i tētahi kiriuhi mai i tētahi waitohu rongonui he maha ngā wā ka whakarite i te kounga me te mahi pumau.
• Ngā Waitohu Pono: Ko ngā waitohu rongonui o te ao ko Dow/Filmtec, Toray, me Hydranautics. He kaha hoki ngā kaitono mō ngā waitohu rongonui o te motu pēnei i a HID.
• Ngā Tiwhikete: Tirohia mēnā he tiwhikete haumaru me te kounga ā-ao pērā i te NSF, i te WQA rānei. Mō ngā hua ā-rohe, ka taea e koe te manatoko mēnā kua rēhitatia ki ngā umanga ahumahi pērā i te China Membrane Industry Association.
