1. Te Whakamahinga i roto i te Horoi Chelating
Ko ngā kaiārahi chelating, e mōhiotia ana ko ngā kaiārahi matatini, ko ngā ligand rānei, ka whakamahi i te matatini (te whakaritenga) me te chelation rānei o ngā momo kaiārahi chelating (tae atu ki ngā kaiārahi matatini) me ngā katote tauine hei whakaputa i ngā matatini wairewa (ngā pūhui whakaritenga) mō ngā kaupapa horoi.
Ngā matū horoihe maha ngā wā ka tāpirihia ki te horoi i ngā matū chelating hei whakatairanga i te tukanga horoi. Ko ngā matū whakakoi kore-waro e whakamahia whānuitia ana ko te sodium tripolyphosphate, ko ngā matū chelating waro e whakamahia whānuitia ana ko te waikawa ethylenediaminetetraacetic (EDTA) me te waikawa nitrilotriacetic (NTA). Ehara i te mea ko te horoi i ngā matū chelating anake te whakamahinga mō te horoi i te pūnaha wai whakamatao engari kua kitea hoki te whanaketanga nui i roto i te horoi i ngā unahi uaua ki te rewa. Nā tōna kaha ki te whakakoi, ki te chelate rānei i ngā katote konganuku i roto i ngā unahi uaua ki te rewa, he pai te horoi.
2. Te Whakamahinga i roto i te Whakakino Hinu Taumaha me te Horoi Whakakino Coke
I roto i ngā whare whakangao hinu me ngā whare hanga matū, he maha ngā wā ka pāngia ngā taputapu whakawhiti wera me ngā paipa e te poke nui o te hinu me te whakatakotoranga o te kōka, e hiahia ana kia horoia pinepine. He tino paitini, he mura, he pahū te whakamahinga o ngā whakarewa waro, engari kāore e whai hua ngā tikanga horoi kawakore whānui ki te poke nui o te hinu me te kōka.
I tēnei wā, ko ngā kaihoroi paru hinu taumaha i whakawhanakehia i roto i te motu me te ao whānui, ko te nuinga o ngā mea e hangai ana ki ngā matū horoi hiato, he mea hanga mai i te huinga o ētahi matū horoi kore-ionic me te anionic, me ngā kaihanga kore-waro me ngā matū kawakore. Ehara i te mea ko ngā matū horoi hiato anake ka puta he pānga pēnei i te mākū, te urunga, te whakaemulsification, te marara, te whakarewatanga, me te pahuka, engari he kaha anō hoki ki te mimiti i te FeS₂. I te nuinga o te wā, me whakamahana ki runga ake i te 80°C hei horoi.
3. Te Whakamahinga i roto i ngā Paturopi Wai Whakamatao
Ina kitea te paru moroiti i roto i ngā pūnaha wai whakamatao, ka whakamahia ngā matū koiora kore-waikura, me ngā matū kore-ionic he iti te pahuka hei whakamarara me hei whakauru, hei whakarei ake i te mahi a ngā matū me te whakatairanga i tō rātou urunga ki roto i ngā pūtau me te paparanga hūpē o te harore.
Hei tāpiritanga, he whānuitia te whakamahinga o ngā matū koiora tote ammonium quaternary. Ko ētahi o ēnei ko ngā matū surfactant cationic, ko ngā mea tino noa ko te benzalkonium chloride me te benzyldimethylammonium chloride. He kaha te kaha o ēnei matū koiora, he ngāwari te whakamahi, he iti te paitini, ā, he iti te utu. Haunga ā rātou mahi ki te tango i te paru me te tango i ngā haunga kino mai i te wai, he pānga aukati waikura anō hoki ō rātou.
Hei tāpiritanga, ko ngā biocides i hangaia mai i ngā tote ammonium quaternary me te methylene dithiocyanate ehara i te mea he whānui te whānuitanga o ngā pānga biocidal me te mahi tahi anake, engari he ārai anō hoki i te tipu o te paru.
