Chlorination a matsayin fasahar bleaching ta gargajiya, ruwan da aka sallameshi daga aikin bleaching yana dauke da gurbatattun abubuwa kamar dioxins, kuma kwayoyin chlorides suna da wahalar kaskantarwa kuma suna gurbata mahalli.
Ana amfani da fasahar Ozone a cikin masana'antar takarda don yin farin ciki da yin ado, gyaran ruwan sha, da ingantaccen ruwan sha. Ozone ya zama mafificin mafita a cikin masana'antar takarda saboda ƙarancin farashi, gurɓatar muhalli da amfani mai yawa.
1. Bishiyar ozone
Ozone shine babban mai sanya fatauci fata. A cikin tsarin bleaching na ɓangaren litattafan almara, ozone yana aiki tare da lignin ɓangaren litattafan almara ta hanyar hadawan abu, wanda ke haifar da chromophore ya rasa ikon “canza launi” kuma ya sami farin jini. Toari da cire abubuwa masu launi, yana ƙara cire lignin da sauran ƙazamta, yana inganta fari da tsarke ɓangaren litattafan almara, kuma yana sanya farin ya zama na ƙarshe.
Fa'idodi na farin ruwan ozone:
1. Barin lemar ozone tsari ne da babu sinadarin chlorine kuma bashi da wata illa ga muhalli;
2. Ozone yana da karfi mai karfi, tare da karfi mai tasiri da inganci;
3. Sauya sinadarin chlorine a cikin aikin bleaching na almakashi don rage hayakin chloride;
4. Yanayin iskar shaka na Ozone yana da sauri, yana rage farashin bilicin;
5, ikon samarda iskar shaka na ozone, inganta farin fari da takarda da rage launin ruwan hoda na ɓangaren litattafan almara.
Ozone ɓangaren litattafan almara ruwan sha
Ozone shine ingantaccen gurɓataccen abu wanda aka yi amfani dashi a cikin tsarin kulawa da ingantaccen ruwan sha na masana'antu. Yana da ayyuka da yawa a cikin maganin ruwa: haifuwa, ƙwarewar abubuwa da kuma bazuwar iska. Ozone galibi ana amfani dashi don ado a cikin ruwa mai tsafta. Rage kwayoyin halitta kuma rage dabi'u na COD da BOD.
Onearancin sakamako mai karfi na ƙwaƙƙwara na iya lalata kwayoyin halittar macromolecule zuwa ƙaramin kwayoyin halitta, canza ƙarancin gurɓataccen gurɓataccen gurɓataccen gurɓataccen abu, da kuma ƙasƙantar da biochemically. A lokaci guda na lalata kwayoyin halitta, COD da BOD sun cancanci a rage don kara inganta ingancin ruwa.
A yayin magance matsalar yawan chromaticity na ruwa mai guba, iskar shaka ta ozone na iya haifar da launin fenti don taimakawa launi ko alakar bivalent na kwayar halittar chromogenic ya karye, kuma a lokaci guda ya ruguza mahallin mai kewaya kungiyar chromophore, game da shi yana lalata ruwan sharar ruwa.
Idan aka kwatanta da aikin chlorine na gargajiya, ozone yana da fa'idodi a cikin masana'antar takarda. Yana da dukiya mai dumbin yawa, saurin gudu kuma babu gurɓataccen yanayi. Ba kawai zai iya rage farashin bilkin na bilki ba, amma kuma zai rage hayaki mai gurbata muhalli. A zamanin yau, kiyaye mahalli ya fi muhimmanci, fasahar ozone ta taka rawar gani.
