NADCC Mahwendefa eSater Kurapa
Nhanganyaya
NaDCC, inozivikanwawo se sodium dichloroisocyanurate, imhando yechlorine inoshandiswa kuuraya utachiona. Inowanzo shandiswa kurapa huwandu hukuru hwemvura munguva dzekukurumidzira, asi inogona zvakare kushandiswa pakurapa mvura yemumba. Mapiritsi anowanikwa aine akasiyana NaDCC zvirimo kubata mavhoriyamu akasiyana emvura panguva imwe chete. Anowanzo nyungudika pakarepo, ane mahwendefa maduku anonyunguduka munguva isingasviki miniti.
Inobvisa sei kusvibiswa?
Kana yawedzerwa kumvura, mahwendefa eNaDCC anoburitsa hypochlorous acid, iyo inopindirana nema microorganisms kuburikidza neoxidation uye inovauraya. Zvinhu zvitatu zvinoitika kana chlorine yawedzerwa kumvura:
Imwe chlorine inopindirana ne organic matter uye utachiona huri mumvura kuburikidza neoxidation uye inovauraya. Ichi chikamu chinonzi chinodyiwa chlorine.
Imwe chlorine inopindirana neimwe organic matter, ammonia, uye iron kuti iumbe makemikari matsva eklorini. Izvi zvinonzi chlorine yakasanganiswa.
Chlorine yakawandisa inoramba iri mumvura isina kudyiwa kana isina kusungwa. Ichi chikamu chinonzi mahara chlorine (FC). FC ndiyo inonyanya kushanda yechlorine yekuuraya utachiona (kunyanya yevhairasi) uye inobatsira kudzivirira kusvibiswa zvakare kwemvura yakabikwa.
Chigadzirwa chega chega chinofanirwa kuve nemirairo yaro yedosi chaiyo. Kazhinji, vashandisi vanotevedzera mirairo yechigadzirwa kuti vawedzere saizi chaiyo mapiritsi ehuwandu hwemvura inogadziriswa. Mvura inobva yabvongodzwa uye inosiiwa kwenguva yakaratidzwa, kazhinji maminitsi makumi matatu (nguva yekubata). Mushure mezvo, mvura inobviswa utachiona uye yakagadzirira kushandiswa.
Kushanda kweklorini kunokanganiswa ne turbidity, organic matter, ammonia, tembiricha uye pH. Mvura ine makore inofanira kusefa kana kubvumidzwa kugara isati yawedzera chlorine. Aya maitiro achabvisa mamwe akamiswa zvidimbu uye anovandudza maitiro pakati peklorini nehutachiona.
Kunobva Mvura Zvinodiwa
low turbidity
pH pakati pe5.5 ne7.5; disinfection haina kuvimbika pamusoro pepH 9
Maintenance
Zvigadzirwa zvinofanirwa kuchengetedzwa kubva pakupisa kwakanyanya kana hunyoro hwepamusoro
Mahwendefa anofanira kuchengetwa kure nevana
Dosage Rate
Mapiritsi anowanikwa aine akasiyana NaDCC zvirimo kubata mavhoriyamu akasiyana emvura panguva imwe chete. Tinogona kugadzirisa mapiritsi maererano nezvaunoda
Nguva Yekurapwa
Kurudziro: maminitsi makumi matatu
Minimum yekuonana nguva inoenderana nezvinhu zvakaita se pH uye tembiricha.
