Ko te tiaki i te puna kaukau te mahi o ia ra kia noho ma te puna. I te wa e tiaki ana i te puna, he rerekematū punae hiahiatia ana kia mau tonu te taurite o nga momo tohu. Ki te pono, ko te wai i roto i te puna he tino marama ka kite koe i te raro, e pa ana ki te toenga o te maota, te pH, te waikawa cyanuric, te ORP, te turbidity me etahi atu mea o te kounga o te wai kaukau.
Ko te mea nui o enei ko te chlorine. Ko te maaota ka whakahaora i nga parahanga pararopi, ka patu i nga pukohu me nga huakita e puta ai te wai puna kapua, me te whakapumau i te marama o te wai puna.
Te waikawa cyanuriche hua hydrolyzate o te waikawa dichloroisocyanuric me te waikawa trichloroisocyanuric, ka taea te tiaki i te chlorine korekore mai i te ultraviolet me te pupuri i te kukū o te waikawa hypochlorous i roto i te wai, na reira ka whakaputa i te paanga whakakino roa. Koia te take i kiia ai te waikawa cyanuric he whakapumau maota, he whakamaarama maaota ranei. Mena he iti iho i te 20 ppm te taumata waikawa cyanuric o te puna kaukau, ka tere te heke o te maota o te puna i raro i te ra. Ki te kore tetahi kai tiaki e whakamahi i te konutai dichloroisocyanurate me te waikawa trichloroisocyanuric i roto i tetahi puna kaukau o waho, engari ka whakamahi i te konupūmā hypochlorite, i te wai tote ranei, me tapiri ano e te kai tiaki te 30 ppm waikawa cyanuric ki te puna.
Heoi, i te mea ehara te waikawa cyanuric i te ngawari ki te pirau me te tango, ka ata whakaemi ki roto i te wai. Ina teitei ake tona kukū i te 100 ppm, ka tino aukatihia e ia te mate whakakino o te waikawa hypochlorous me te. I tenei wa, kei te pai te toenga o te panui maaota engari ka tupu pea te pukohu me te huakita, ka huri ma te wai puna, ka kaariki ranei. Ko tenei e kiia nei ko te "rakau maota". I tenei wa, ko te taapiri tonu i te maota kaore e awhina.
Te tikanga maimoatanga tika mo te raka maota: Whakamatautauria te taumata waikawa cyanuric o te wai puna, katahi ka whakamakuku i tetahi wahi o te wai puna ka whakakiia te puna ki te wai hou. Hei tauira, ki te mea he puna kaukau koe he 120 ppm te taumata o te waikawa cyanuric, na ko te paheketanga o te wai e hiahia ana koe kia rere ko:
(120-30)/120 = 75%
I te nuinga o te wa ka whakawhiwhia te taumata waikawa cyanuric ma te turbidimetry:
Whakakiia te pounamu whakaranu ki te tohu o raro ki te wai puna. Whakaki tonu ki te tohu o runga ki te reagent. Kapihia ka ruia te pounamu ranu mo te 30 hēkona. Tu ki waho me to tuara ki te ra ka pupuri i te ngongo tirohanga kia rite ki te taumata hope. Mena kaore i te waatea te ra, kimihia te rama hangai tino marama ka taea e koe.
Ka titiro whakararo ki roto i te ngongo tiro, kia ata ringihia te ranunga mai i te pounamu ranu ki te ngongo tirohanga. Me riringi tonu kia ngaro katoa nga tohu o te ira pango kei raro o te ngongo tiro, ahakoa ka tiro koe mo etahi hēkona.
Te panui i te hua:
Mena kua ki tonu te ngongo tiro, ka kite tonu koe i te ira pango, he kore to taumata CYA.
Mēnā kua kī katoa te ngongo tiro, ā, kua pōuri noa te ira pango, kei runga ake tō taumata CYA engari kei raro iho i te taumata iti rawa ka taea e to kete whakamatautau te ine (20, 30 ppm ranei).
Tuhia te hua CYA i runga i te tohu tata.
Mena he 90 neke atu ranei to taumata CYA, whakahoki ano i te whakamatautau me te whakatika i te tikanga penei:
Whakakiia te pounamu whakaranu ki te tohu o raro ki te wai puna. Me whakakī tonu te pounamu whakaranu ki te tohu o runga ki te wai tap. Ruperupea poto kia uru. Ringihia te haurua o nga mea kei roto i te pounamu whakaranu, kia whakakiia ano ki te tohu o raro. Me haere tonu te whakamatautau mai i te taahiraa 2, engari whakareatia te hua whakamutunga ki te rua.
He maamaa ake a maatau takai whakamatautau ki te whakamatautau i te waikawa cyanuric. Toua te riipene whakamatautau ki te wai, tatari mo nga hēkona kua tohua ka whakatairitehia te takai ki te kaari tae paerewa. I tua atu, ka whakaratohia ano e matou nga momo matū puna kaukau. Tena koa waiho mai he korero ki a au mena kei a koe etahi hiahia.
