Ko te whakautu poto he ae. Ko te waikawa cyanuric ka whakaheke i te pH o te wai puna.
Ko te waikawa cyanuric he tino waikawa me te pH o te 0.1% waikawa cyanuric wairewa he 4.5. Ko te ahua karekau i te tino waikawa i te mea ko te pH o te 0.1% te wairewa konutai bisulfate he 2.2 me te pH o te 0.1% te waikawa puota he 1.6. Engari kia mahara ko te pH o nga puna kaukau kei waenganui i te 7.2 me te 7.8 me te pKa tuatahi o te waikawa cyanuric he 6.88. Ko te tikanga ko te nuinga o nga ngota ngota waikawa cyanuric i roto i te puna kaukau ka taea te tuku i te katote hauwai me te kaha o te waikawa cyanuric ki te whakaheke i te pH he tino tata ki te konutai bisulfate e whakamahia ana hei whakaiti pH.
Hei tauira:
He puna kaukau o waho. Ko te pH tuatahi o te wai puna he 7.50, ko te tapeke kawakore he 120 ppm, ko te taumata waikawa cyanuric he 10 ppm. Kei te pai nga mea katoa engari mo te taumata waikawa cyanuric kore. Me tapiri atu te 20 ppm o te waikawa cyanuric maroke. Ka memeha haere te waikawa cyanuric, i te nuinga o te waa 2 ki te 3 ra. Ina memeha katoa te waikawa cyanuric ko te pH o te wai puna ka 7.12 he iti iho i te rohe iti o te pH (7.20). 12 ppm o te konutai warowaiha me te 5 ppm o te konutai waikawa hei tapiri hei whakatika i te raruraru pH.
Ko te wai monosodium cyanurate, he slurry ranei kei etahi toa poka wai. 1 ppm monosodium cyanurate ka piki ake te taumata waikawa cyanuric ma te 0.85 ppm. Ko te Monosodium cyanurate he tere te wairewa i roto i te wai, no reira he pai ake te whakamahi me te tere ake te whakanui ake i nga taumata waikawa cyanuric i roto i te puna kaukau. He rereke ki te waikawa cyanuric, he kawakore te wai monosodium cyanurate (ko te pH o te 35% slurry kei waenga i te 8.0 ki te 8.5) me te whakanui paku te pH o te wai puna. I roto i te puna kaukau kua whakahuahia ake nei, ka piki te pH o te wai puna ki te 7.68 i muri i te taapiri i te 23.5 ppm o te monosodium cyanurate parakore.
Kaua e wareware ko te waikawa cyanuric me te monosodium cyanurate i roto i te wai puna ka mahi ano hei parepare. Arā, ko te teitei ake o te taumata waikawa cyanuric, ka iti ake te heke o te pH. Na kia mahara ki te whakamatautau ano i te tapeke kawakore ina hiahiatia te pH o te wai puna ki te whakatika.
Kia mahara hoki he kaha ake te kaha o te waikawa cyanuric i te konutai warowaiha, no reira me taapiri atu he waikawa, he kawakore ranei i te kore waikawa cyanuric.
Mo te puna kaukau kei te 7.2 te pH tuatahi me te 7.5 te pH e hiahiatia ana, ko te tapeke kawakore he 120 ppm ko te taumata waikawa cyanuric he 0, me 7 ppm o te konutai warowaiha kia tutuki ai te pH e hiahiatia ana. Kia mau ki te pH tuatahi, te pH e hiahiatia ana me te tapeke kawakore he 120 ppm kaore i whakarereketia engari huri i te taumata waikawa cyanuric ki te 50 ppm, me 10 ppm o te konutai warowaiha inaianei.
I te wa e tika ana kia whakahekehia te pH, he iti ake te paanga o te waikawa cyanuric. Mo te puna kaukau kei te 7.8 te pH tuatahi me te pH e hiahiatia ana ko te 7.5, ko te tapeke kawakore he 120 ppm me te taumata waikawa cyanuric he 0, me 6.8 ppm o te konutai bisulfate hei whakatutuki i te pH e hiahiatia ana. Kia mau ki te pH tuatahi, te pH e hiahiatia ana me te tapeke kawakore he 120 ppm kaore i whakarereke engari huri i te taumata waikawa cyanuric ki te 50 ppm, me 7.2 ppm o te konutai bisulfate - he 6% anake te piki o te inenga o te konutai bisulfate.
He painga ano te waikawa cyanuric ki te kore e hanga tauine ki te konupūmā me etahi atu konganuku.
