Chothandizira Kuchotsa Utoto wa Madzi Onyansa - Kodi Zimatenga Nthawi Yaitali Bwanji Kuti Chothandizira Kuchotsa Utoto wa Madzi Onyansa Chichitepo Kanthu Pambuyo Polowa M'madzi Onyansa?

Mawu Ofunika: Chotsukira utoto cha madzi otayira, chotsukira utoto cha flocculant

Pamene chotsukira madzi otayira chilowetsedwa mu thanki ya madzi otayira, kachitidwe kojambula mitundu kakang'ono kamayamba. Palibe nthawi yokhazikika yoti chotsukiracho chichitepo kanthu kotheratu; pansi pa mikhalidwe yabwino, chimagwira ntchito mkati mwa mphindi zochepa, pomwe pansi pa mikhalidwe yovuta ya madzi, njira yonseyi simatenga nthawi yoposa theka la ola.

Masekondi ochepa oyamba pambuyo poti mankhwalawa alowa m'madzi ndi pomwe gawo la kufalikira ndi kusokonekera limayamba. Pansi pa kayendedwe ka madzi kapena kugwedezeka, mankhwalawa amafalikira mofulumira, ndipo mamolekyu amatengera tinthu tamitundu m'madzi. Pakatha mphindi imodzi kapena ziwiri, ma floc ang'onoang'ono amayamba kupangika m'madzi, ndipo zonyansa zambiri zamitundu zimamaliza kumangidwa kwawo koyamba.

Mphindi zitatu kapena zisanu zotsatira ndi gawo lofunika kwambiri la kusonkhana ndi kukula kwa ma floc. Ma floc ang'onoang'ono amagundana ndi kusonkhana, kukula ndi kulemera kumawonjezeka mosalekeza ngati mpira wa chipale chofewa, zomwe zimapangitsa kuti utoto m'madzi ukhale wofanana ndi wa m'madzi. Pa gawoli, mphamvu ya utoto wamba ndi madzi otayira m'nyumba imatha kufika pa 90%, ndipo pang'onopang'ono madziwo amaonekera bwino.

Pomaliza, gawo la kutayikira ndi kulekanitsa limayamba. Ma floc opangidwawo amakhazikika ndi mphamvu yokoka, nthawi zambiri amafunika mphindi zisanu mpaka khumi kuti amalize kulekanitsa matope ndi madzi. Pa madzi otayira ovuta kuwakonza okhala ndi utoto ndi mafuta osinthika, zinyalala zamitundu zimakhala zovuta kuzigwira, zomwe zimapangitsa kuti nthawi yonse yochitira zinthuyo ifike pa mphindi khumi ndi zisanu mpaka makumi awiri.

Kuchuluka kwa zomwe zimachitika kumakhudzidwa ndi zinthu zingapo: kugwedezeka bwino kumathandizira kufalikira kwa reagent; malo abwino okhala ndi alkaline pang'ono m'madzi amawonjezera ntchito ya reagent; ndipo kutentha kochepa kumachepetsa kuyenda kwa tinthu, zomwe zimawonjezera nthawi yochitira.

Mwachidule, pa madzi otayira wamba, kuwonjezera zinthu zochotsa utoto kumathetsa vutoli mkati mwa mphindi khumi mpaka khumi ndi zisanu, zomwe zimapangitsa kuti madzi asakhale ndi matope; ngakhale pa madzi otayira okhala ndi utoto wokhuthala, njira yonse yochotsera utoto ndi kuyika matope nthawi zambiri siipitirira theka la ola. Zotsatira zingapo zosalekeza za microscopic zimagwira utoto m'madzi otayira omwe ali mkati mwa matope, zomwe zimapangitsa kuti madzi otayirawo awoneke bwino ndikuwonetsetsa kuti akutsatira miyezo.
