Chlorination monga ukadaulo wachikhalidwe, madzi onyansa omwe amatulutsidwa kuchokera ku njira yoyera magazi amakhala ndi zoipitsa monga ma dioxin, ndipo ma organic chloride ndi ovuta kunyoza ndikuwononga chilengedwe.
Tekinoloje ya Ozone imagwiritsidwa ntchito m'makampani opanga mapepala kuti apange buluku ndi kutsitsa, kusungunuka kwa madzi ogwiritsidwa ntchito, komanso chithandizo chamankhwala apamwamba. Ozone yakhala yankho losankhika m'makampani opanga mapepala chifukwa chotsika mtengo, kuwononga chilengedwe komanso kugwiritsa ntchito kwambiri.
1. Mpweya wabwino wa zamkati
Ozone ndi othandizira kwambiri kuti azisungunuka. Mu dongosolo la zamkati zamkati, ozoni imagwirana ndi zamkati lignin kudzera munjira ya okosijeni, yomwe imapangitsa kuti chromophore itaye mphamvu yake ya "utoto" ndikukwaniritsa kuyeretsa. Kuphatikiza pa kuchotsa zinthu zakuda, imachotsanso zotsalira za lignin ndi zodetsa zina, imathandizira kuyera ndi kuyera kwa zamkati, ndikupangitsa kuyera kuti kukhaleko.
Ubwino wa ozoni oyeretsa:
1. Mpweya wabwino wa ozoni ndi njira yopanda klorini ndipo ilibe kuipitsa chilengedwe;
2. Ozone ndi cholumikizira cholimba, chokhala ndi mphamvu yayikulu yotsegulanso komanso kuchita bwino kwambiri;
3. Sinthanitsani mankhwala a klorini mu ndondomeko yamkati ya zamkati kuti muchepetse mpweya wa mankhwala enaake;
4. Ozone makutidwe ndi okosi anachita ndi mofulumira, kuchepetsa mtengo wa oyeretsa;
5, Mpweya umene makutidwe ndi okosijeni luso, kusintha whiteness pepala ndi kuchepetsa chikasu zamkati.
Chithandizo chamadzimadzi amkati
Ozone ndi cholumikizira cholimba chomwe chimagwiritsidwa ntchito popanga chithandizo chamankhwala chisanafike pochiza madzi akumwa. Ili ndi ntchito zambiri pochiza madzi: yolera yotseketsa, kuwonongeka kwa madzi ndi kuwonongeka kwa okosijeni. Mpweya umene umagwiritsidwa ntchito makamaka pochotsera zimbudzi m'mayendedwe amadzi. Onetsani zachilengedwe ndikuchepetsa mitengo ya COD ndi BOD.
Mpweya wolimba wa ozoni ungathe kuwononga chilengedwe cha macromolecule kukhala zinthu zazing'ono, kusintha kawopsedwe ka zoipitsa, ndikuwononga mwachilengedwe. Nthawi yomweyo zinthu zonyoza, COD ndi BOD zikuyenera kuchepetsedwa kuti zithandizire kupititsa patsogolo madzi.
Polimbana ndi vuto lakuthwa kwakukulu kwa madzi onyansa, ozoni makutidwe ndi okosijeni amatha kupangitsa mtundu wa utoto kuti uthandizire utoto kapena mgwirizano wosakanikirana wa jini la chromogenic kuti usweke, ndikuwononga nthawi yayitali yopanga gulu la chromophore, potero adasungunula madziwo.
Poyerekeza ndi njira yachikhalidwe ya chlorine, ozoni ali ndi mwayi woonekeratu pamakampani opanga mapepala. Ili ndi malo olimba okosijeni, othamanga kwambiri komanso osawononga chilengedwe. Sizingathe kuchepetsa mtengo wamkati wamkati, komanso kuchepetsa mpweya woipa. Masiku ano, kuteteza zachilengedwe ndikofunika kwambiri, ukadaulo wa ozoni wachita gawo lalikulu.
