In te maimoatanga waipara ahumahi, he hononga matua te tango i ngā totoka iri. Ehara i te mea ka āwhina noa tēnei ki te whakapai ake i te kounga o te wai, engari ka whakaitihia hoki te pakaru me te haehae o ngā taputapu me te aukati. I tēnei wā, ko ngā tikanga mō te tango i ngā totoka iri ko te whakatōpuku, te tātari, te whakapūmau me te whakapūmau. I roto i ēnei, e whakamahia whānuitia ana te tikanga whakapūmau nā te mea he tino whai hua me te ohanga. I roto i tēnei huarahi, he mahi nui tā te polymer e kiia nei ko PolyDADMAC.
Ko te PolyDADMAC, ko tōna ingoa katoa ko te Poly diallyl dimethyl ammonium chloride, he pūmua ngota teitei. Ko te nuinga o te wā ka hangaia mā te whakakotahi i te monomer diallyldimethylammonium chloride mā te whakakotahitanga tipu mekameka. Ko tēnei tauhohenga whakakotahitanga ka mahia i raro i te whakaterenga o te waikawa, te tote rānei, ā, ka taea te whiwhi i tētahi pūmua hanganga rārangi. Ko te tikanga he wai kōwhai, he paura mā ki te kōwhai, he pūmua rānei. He pai te wairewa, ā, ka taea te horapa ōrite ki roto i ngā otinga wai.
PolyDADMACHe nui te mātotoru o te utu, ā, he rite tonu tana mahi ki te pūmua cationic. Ko te tikanga ka taea e ia te mimiti i ngā totoka whakatārewatia me ngā matūriki colloidal kua utua kinotia ki roto i te wai hei hanga i ngā putunga nui, ā, ka tutuki ai te tango whai hua i ngā totoka whakatārewatia. He maha ngā wā ka whakamahia te PolyDADMAC hei putunga me te whakakōkī, ā, he whānuitia te whakamahinga i roto i ngā momo mara maimoatanga wai, tae atu ki te maimoatanga wai para ahumahi me te maimoatanga wai para tāone. Ka taea e ia te hanga tere i ngā putunga nui me te mātotoru i roto i te wai para, ā, ka tangohia whai hua ngā totoka whakatārewatia, ngā katote konganuku taumaha me ngā poke rauropi.
I roto i te maimoatanga o te wai para mai i ngā mira penupenu me te pepa, ko te tikanga mahi a PolyDADMAC e whakaatahia ana i roto i ngā āhuatanga e whai ake nei:
Te whakakore i te utu: Nā te mea he nui te kiato utu o te PolyDADMAC, ka tere te mimiti ki runga i ngā totoka iri me ngā matūriki colloidal kua utua kinotia, ka ngaro te pumau i te whakakore i te utu, kātahi ka huihui hei hanga i ngā puranga matūriki nunui.
Te mahi horoi: I te hanganga o te para, ka kukumea ngā totoka iri me ngā matūriki colloidal i roto i te wai para ki roto i te para, ka tutuki ai te wehenga totoka-wai mā te mahi ā-tinana.
Pānga hopu kupenga: Ka taea e ngā pūmua ngota-tiketike te hanga i tētahi hanganga whatunga kikī, ka mau ai ngā totoka iri me ngā matūriki korori ki roto pērā i te kupenga hī ika, ā, ka tutuki ai te wehenga whai hua.
Ki te whakatauritea ki ētahi atu tikanga maimoatanga waipara, ko ngā painga o te whakamahi i te PolyDADMAC hei maimoatanga i te waipara o te mira penupenu me te pepa he penei:
Teitei o te kiato utu: Mā te nui o te kiato utu o PolyDADMAC ka taea e ia te mimiti pai ake i ngā totoka iri me ngā matūriki colloidal kua utua kinotia, ka pai ake te whai huatanga o te maimoatanga.
Kaha te urutau: He pai ngā pānga maimoatanga a PolyDADMAC ki ngā momo wai para penupenu me te pepa, ā, kāore e pāngia e ngā piki me ngā heke o te kounga wai.
Te whai huatanga teitei me te iti o te whakamahinga: Te whakamahi i te PolyDADMAC heiKaiwhakarewa waiā, ka taea e te matū whakakōkī te whakaiti i te horopeta o ngā matū, me te whakapai ake i te whai huatanga o te maimoatanga me ngā utu whakahaere.
He pai mō te taiao: He pūhui kationika te PolyDADMAC. Kāore e ngāwari te pirau o te floc i muri i te whakamahinga hei matū kino, ā, he pai hoki mō te taiao.
Hei whakamutunga, ko PolyDADMAC, heiPūmua Irahiko Teitei, he pai te mahi, he iti te whakamahinga, he pai hoki mō te taiao, ā, he mea nui hoki ki te rongoā i ngā wai para mai i ngā mira penupenu me te pepa. I tēnei wā e uaua ana te ātete ki te ia o te tiaki taiao, he hua matū rongonui a PolyDADMAC e tutuki ana i ngā āhuatanga o ngā hua pai mō te taiao.
