Parwendo, ndakasarudza kugara muhotera yaiva pedyo nechiteshi chechitima. Asi pandakabatidza pombi, ndakanzwa kunhuwa kwechlorine. Ndaida kuziva, saka ndakadzidza zvakawanda nezvekuchenesa mvura yemupombi. Unogona kunge wakasangana nedambudziko rakafanana nerangu, saka rega ndikupindure.
Kutanga kwazvose, isu tinofanirwa kunzwisisa kuti mvura yemupombi inopinda nei isati yayerera ichipinda munetiweki network.
Muhupenyu hwezuva nezuva, kunyanya mumaguta, mvura yepombi inobva mumiti yemvura. Mvura yakasvibirira yakawanikwa inoda kurapwa kwakatevedzana muchirimwa chemvura kuti isangane nezviyero zvemvura yekunwa. Sekutanga kumira kutipa mvura yekunwa yakachengeteka, chirimwa chemvura chinoda kubvisa zvinhu zvakasiyana-siyana zvakamiswa, colloids, uye zvakanyungudutswa mumvura yakasvibirira kuburikidza neimwe nzira yekuchenesa mvura kuti ive nechokwadi chezvinodiwa zvekunwa kwezuva nezuva uye kugadzirwa kwemaindasitiri. Iyo yakajairika kurapwa maitiro inosanganisira flocculation (inowanzo shandiswa flocculants ndeye polyaluminium chloride, aruminiyamu sulfate, ferric chloride, nezvimwewo), kunaya, kusefa uye disinfection.
Iyo disinfection process ndiyo sosi yekunhuhwirira kweklorini. Parizvino, nzira dzinowanzoshandiswa dzekuuraya hutachiona mumiti yemvura ndedzipichlorine disinfection, chlorine dioxide disinfection, ultraviolet disinfection kana ozone disinfection.
Ultraviolet kana ozone disinfection inowanzoshandiswa pamvura yemubhodhoro, iyo inoiswa zvakananga mushure mekuuraya hutachiona. Zvisinei, haina kukodzera kutakura pombi.
Chlorine disinfection inzira yakajairika yekubvisa hutachiona hwepombi mvura kumba nekune dzimwe nyika. Iwo ma chlorine disinfectants anowanzo shandiswa mumishonga yekuchenesa mvura chlorine gasi, chloramine, sodium dichloroisocyanurate kana trichloroisocyanuric acid. Kuchengetedza kuuraya hutachiona hwemvura yemupombi, China kazhinji inoda iyo yakazara chlorine inosara mumvura inopera kuti ive 0.05-3mg/L. Muyero weUS unosvika 0.2-4mg/L zvinoenderana nenzvimbo yaunogara. Kuti uve nechokwadi chekuti mvura yemuguri inogonawo kuva neimwe nzira yekuuraya utachiona, iyo chlorine iri mumvura inochengetedzwa pamutengo mukuru weiyo yakatarwa. (2mg/L muChina, 4mg/L muUnited States) apo mvura yemupombi inobva mufekitari.
Saka kana wava pedyo nechirimwa chemvura, unogona kunhuwa kunhuhwirira kwakasimba kweklorini mumvura kupfuura panoperera. Izvi zvinoreva zvakare kuti panogona kunge paine pombi yekuchenesa mvura yepombi padyo nehotera yandaimbogara (yakatariswa kuti nhambwe yakatwasuka pakati pehotera nekambani yemvura i2km chete).
Sezvo mvura yemupombi iine chlorine, iyo inogona kuita kuti unhuwe kana kutombonaka zvisingafadzi, unogona kufashaidza mvura yacho, woita kuti itonhore, wozonwa. Kubika inzira yakanaka yekubvisa chlorine kubva mumvura.
