Umthengisi weBromine eMzantsi Afrika

Yintoni iBromine yoNyango lwaManzi?

I-Bromine yinxalenye ye-halogen (iQela 17) esetyenziswa njenge-biocide ekhupha i-oxidizing kunyango lwamanzi, ngakumbi kwiinkqubo zamanzi okupholisa kwimizi-mveliso kunye nokusetyenziswa kwamanzi afudumeleyo (ii-spa, iibhafu ezishushu, amachibi ashushu). Kunyango lwamanzi, i-bromine ayisetyenziswa njenge-elemental liquid bromine (i-Br₂, ulwelo olumdaka olurhabaxa noluvuthayo) kodwa isetyenziswa njengeekhompawundi ezivelisa i-bromine okanye iinkqubo ze-sodium bromide ezisebenzayo. Iipilisi ze-BCDMH (1-bromo-3-chloro-5,5-dimethylhydantoin) zikhupha i-bromine kancinci emanzini. Ngaphandle koko, i-sodium bromide (NaBr) idityaniswe ne-oxidant (chlorine, i-hydrogen peroxide, okanye i-ozone) ukuvelisa i-hypobromous acid (HOBr) in situ - uhlobo lwe-biocidal olusebenzayo.

Iingenelo ngaphezu kweChlorine kwi-pH ephezulu

Inzuzo ephambili ye-biocides esekelwe kwi-bromine ngaphezu kwe-chlorine kukugcina ukusebenza kwayo kwi-biocidal kuluhlu olubanzi lwe-pH. I-Hypochlorous acid (i-HOCl, uhlobo olusebenzayo lokubulala iintsholongwane oluvela kwi-chlorine) kwi-pH 8.0 iquka kuphela i-~21% ye-chlorine iyonke, kwaye enye injenge-hypochlorite engasebenzi kangako (OCl⁻). Ngokwahlukileyo koko, i-hypobromous acid (i-HOBr, uhlobo olusebenzayo lwe-bromide) ihlala iphambili ukuya kuthi ga kwi-pH ~8.5, okwenza i-bromine ibe nempumelelo engaphezulu kwe-3-5× kune-chlorine ngokwesisindo kwi-cooling tower eqhelekileyo kunye ne-spa pH (7.5-8.5). Oku kwenza i-bromine ibe yi-biocide ekhethwayo kwii-cooling towers kunye nee-spas apho i-pH igcinwa ngabom kwi-7.5-9.0 yokulawula isikali kunye nokugqwala.

I-Spa, i-Hot Tub, kunye nezicelo zamanzi afudumeleyo

I-Bromine sisixhobo sokucoca esiqhelekileyo samachibi e-spa kunye neebhafu ezishushu kuba sisebenza kakuhle xa kushushu kakhulu amanzi (50–40°C), asivelisi ukurhawuzelelwa kwamehlo nolusu okunxulunyaniswa ne-chloramines xa kushushu kakhulu, kwaye sisebenza kakuhle xa kushushu kakhulu amanzi e-spa afakwe i-carbonate. I-Terracore Chemicals inika i-bromine njengeepilisi ze-BCDMH, i-sodium bromide (kwiinkqubo ze-bromide ezisebenzayo), kwaye inika iingcebiso ngeenkqubo zonyango lwamanzi ezisekelwe kwi-bromine zokupholisa amanzi kunye nokusetyenziswa kwamanzi okuzonwabisa.
