Me pēhea te whakamahi i ngā matū maimoatanga wai 1

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 ki te 20-30 ℃, ka tere ake te memeha. Engari kia tino mohio kei raro iho te pāmahana i te 60 ℃.

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 matū whakapūkara kohu peita: (Ngā matū e whakamahia ana mō te maimoatanga paru peita)

1. I te mahi peita, tāpirihia te matū whakakōkī peita A i te ata, kātahi ka rehuhia te peita kia rite ki te tikanga. Hei whakamutunga, tāpirihia te matū whakakōkī peita B i te hawhe haora i mua i te wehenga atu i te mahi.

2. Kei te pūwāhi e tomo ai te wai e rere ana te pūwāhi e ine ai te matū whakakōkī peita A, ā, kei te putanga mai o te wai e rere ana te pūwāhi e ine ai te matū B.

3. Whakatikatikahia te nui o te kohu peita whakapūkara A me B i te wā tika, kia rite ki te nui o te peita rehu me te nui o te wai e rere ana.

4. Me ine i te pH o te wai e rere ana i ngā wā katoa, kia rua ngā wā i te rā, kia noho tonu i waenga i te 7.5-8.5, kia pai ai te pānga o tēnei rongoā.

5. Ina whakamahia te wai e rere ana mō tētahi wā, ka nui ake te kawe hiko, te uara SS me te nui o ngā totoka i whakatārewatia o te wai e rere ana i tētahi uara kua whakaritea, ā, ka uaua te whakarewa i tēnei matū ki roto i te wai e rere ana, ā, ka pā ki te pānga o tēnei matū. E taunakihia ana kia horoia te tāke wai me te whakakapi i te wai e rere ana i mua i te whakamahinga. Ko te wā whakawhiti wai e pā ana ki te momo peita, te nui o te peita, te āhuarangi me ngā āhuatanga motuhake o ngā taputapu paninga, ā, me whakatinana kia rite ki ngā taunakitanga a te tohunga hangarau o te wāhi.
