Me pēhea te whakamahi i ngā matū maimoatanga wai 3

Ka nui ake tā mātou aro ki te rongoā i ngā wai para i te wā e kino haere ana te parahanga o te taiao. He āwhina ngā matū rongoā wai e tika ana mō ngā taputapu rongoā wai para. He rerekē ngā pānga me ngā tikanga whakamahi o ēnei matū. I konei ka whakaatuhia ngā tikanga whakamahi mō ngā matū rongoā wai rerekē.

I.Polyacrylamide mā te whakamahi i te tikanga: (Mō te ahumahi, te kakahu, te paru o te taone me ētahi atu)

1. Whakaranua te hua hei wairewa 0.1%-0.3%. He pai ake te whakamahi i te wai māori, kāore he tote i te wā e whakaranua ana. (Pērā i te wai puna)

2. Kia mōhio mai: I te wā e whakawaiwai ana i te hua, me whakahaere te tere rere o te mīhini inenga aunoa, kia kore ai e kohikohi, e ārai i te āhua o te kanohi ika, e aukati rānei i ngā paipa.

3. Me neke atu i te 60 meneti te roa o te whakaoho me te 200-400 rōra/min. He pai ake te whakahaere i te pāmahana wai kia 20-30℃,mā tēnā ka tere ake te memeha. Engari kia tino mōhio kei raro iho i te 60 te pāmahana℃.

4. Nā te whānuitanga o te pH ka taea e tēnei hua te whakarerekē, ka taea te whakarite i te horopeta mai i te 0.1-10 ppm, kia rite ki te kounga o te wai.

Me pēhea te whakamahi i te polyaluminium chloride: (e pā ana ki te ahumahi, te tā me te tae, te wai para o te tāone, me ētahi atu)

　　1. Whakarewahia te hua pūhaumāota polyaluminum totoka ki te wai i te ōwehenga o te 1:10, whakaohokia, kātahi ka whakamahia.

　　2. Ka taea te whakatau i te horopeta tino pai i runga i te rerekētanga o te paru o te wai mata. I te nuinga o te wā, ina he 100-500mg/L te paru o te wai mata, ko te horopeta he 10-20kg ia mano tana.

　　3. Ka taea te whakanui ake i te horopeta ina teitei te paru o te wai mata; ka taea te whakaiti i te horopeta ina iti te paru.

　　4. Ka whakamahia ngātahitia te polyaluminium chloride me te polyacrylamide (anionic, cationic, non-ionic) mō ngā hua pai ake.
