Kodi zosefera za carbon activated zimatulutsa chiyani m'madzi apampopi?

Zosefera za kaboni zomwe nthawi zina zimatchedwa kuti zosefera zamakala zimakhala ndi tinthu tating'ono ta kaboni, tating'ono ting'onoting'ono kapena totchinga, tomwe timakhala tambiri tambiri.Ma magalamu 4 okha a carbon activated ali ndi malo ofanana ndi bwalo la mpira(6400 sqm).Ndilo gawo lalikulu lomwe limalola zosefera za kaboni kuti zikhale zogwira mtima kwambiri pakutsatsa (kuchotsa) zowononga ndi zinthu zina.

Pamene madzi akuyenda kudzera yogwira zosefera mpweya mankhwala kumamatira mpweya chifukwa purer madzi linanena bungwe.Kuchita bwino kumadalira kuyenda ndi kutentha kwa madzi.Choncho zosefera zing'onozing'ono zogwira ntchito za carbon ziyenera kugwiritsidwa ntchito ndi mphamvu yochepa komanso madzi ozizira.

Kuwonjezera padziko yogwira mpweya Zosefera angakhale ndi mphamvu zosiyana malinga ndi kukula kwa zoipitsa iwo kuchotsa.Chinthu chimodzi ndi khalidwe la carbon activated yokhala ndi zipolopolo za kokonati zomwe zatsimikiziridwa kuti ndizochita bwino kwambiri.Mpweya wokhala ndi activated ukhozanso kupangidwa ndi matabwa kapena malasha ndikugulitsidwa ngati matabwa opangidwa ndi granular kapena kaboni.

Chinthu chinanso ndi kukula kwa tinthu tating'onoting'ono tosefera titha kuloleza chifukwa izi zimapereka chitetezo chachiwiri.Granular activated carbon (GAC) ilibe malire enieni chifukwa zinthu zake ndi porous.Mpweya wopangidwa ndi mpweya wofanana ndi zitsulo za carbon kumbali inayo nthawi zambiri zimakhala ndi pore kukula kwapakati pa 0,5 mpaka 10 micron.Vuto la tinthu tating'onoting'ono tating'ono ndikuti madzi oyenda amatha kuchepetsedwa pomwe tinthu tamadzi timavutikira.Chifukwa chake midadada ya kaboni imakhala pakati pa 1-5 micron.

Activated carbon ikhoza kukhala yothandiza mukuchepetsa mazana a zinthu kuphatikizapo zowononga ndi mankhwala ena kuchokera m'madzi a pampopi.Komabe, maphunziro omwe atchulidwa kwambiri ndiEPAndiNSFkunena kuti kuchotsedwa kwabwino kwa mankhwala apakati pa 60-80, kutsika kothandiza kwa ena 30 ndikuchepetsa pang'ono kwa 22.

Kuchotsa kothandiza ndikofunikira ndipo kumadalira mtundu wa kaboni wogwiritsidwa ntchito komanso mawonekedwe otani (GAC vs carbon block).Onetsetsani kuti mwasankha fyuluta yomwe imachotsa zodetsa nkhawa zamadzi apampopi apafupi.
