Ferric Chloridendi mankhwala omwe ali ndi fomula FeCl3. Amagwiritsidwa ntchito kwambiri pochiza madzi ngati coagulant chifukwa cha mphamvu yake pochotsa zonyansa ndi zowonongeka m'madzi ndipo nthawi zambiri amagwira ntchito bwino m'madzi ozizira kuposa alum. Pafupifupi 93% ya ferric chloride imagwiritsidwa ntchito poyeretsa madzi, mwachitsanzo, madzi oipa, zimbudzi, madzi ophikira ndi madzi akumwa. Ferric chloride imagwiritsidwa ntchito kwambiri ngati njira yothetsera madzi ndi madzi oyipa.
Kugwiritsa ntchito ferric chloride pochiza madzi:
1. Coagulation ndi Flocculation: Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ferric chloride pochiza madzi ndi ngati coagulant. Akawonjezeredwa m'madzi, ferric chloride imakhudzidwa ndi madzi kuti ipange ferric hydroxide ndipo yotsirizirayi imatulutsa tinthu tating'onoting'ono, tinthu tating'onoting'ono, ndi zonyansa zina kupanga tinthu tokulirapo, zolemera kwambiri zotchedwa flocs. Ma flocs amatha kukhazikika mosavuta panthawi ya sedimentation kapena kusefera, zomwe zimapangitsa kuti zichotsedwe m'madzi zichotsedwe.
2. Kuchotsa Phosphorus: Ferric chloride imathandiza kwambiri kuchotsa phosphorous m'madzi. Phosphorus ndi michere yodziwika bwino yomwe imapezeka m'madzi otayidwa, ndipo kuchuluka kwambiri kumatha kubweretsa eutrophication polandira matupi amadzi. Ferric chloride imapanga zinthu zosasungunuka ndi phosphorous, zomwe zimatha kuchotsedwa kudzera mumvula kapena kusefera, zomwe zimathandiza kuchepetsa kuchuluka kwa phosphorous m'madzi.
3. Kuchotsa Chitsulo Cholemera: Ferric chloride imagwiritsidwanso ntchito kuchotsa zitsulo zolemera, monga arsenic, lead, ndi mercury, m’madzi. Zitsulozi zimatha kukhala zapoizoni kwambiri ndipo zimatha kukhala ndi thanzi labwino ngati zili m'madzi akumwa. Ferric chloride amapanga insoluble metal hydroxides kapena zitsulo oxychlorides, zomwe zimatha kuchotsedwa kudzera mumvula kapena kusefera, ndikuchepetsa kuchuluka kwa zitsulo zolemera m'madzi.
4. Kuchotsa Mitundu ndi Kununkhira: Ferric chloride imathandiza kuchotsa mitundu ndi fungo lamadzi. Imasungunula zinthu zachilengedwe zomwe zimapangitsa mtundu ndi fungo, kuziphwanya kukhala zinthu zing'onozing'ono, zosatsutsika. Izi zimathandiza kukonza kukongola kwa madzi, kuwapangitsa kukhala oyenera kumwa, mafakitale, kapena zosangalatsa.
5. Kusintha kwa pH: Poyang'anira pH, ferric chloride ikhoza kupititsa patsogolo ntchito za njira zina zothandizira, monga coagulation, flocculation, ndi disinfection. Mtundu wabwino wa pH ukhoza kuthandizira kupanga malo abwino ochotsera zonyansa ndi zonyansa m'madzi.
6. Disinfection Byproduct Control: Ferric chloride ingathandize kuwongolera mapangidwe a disinfection byproducts (DBPs) panthawi yamankhwala amadzi. Mukagwiritsidwa ntchito limodzi ndi mankhwala ophera tizilombo toyambitsa matenda monga chlorine, ferric chloride ikhoza kuchepetsa mapangidwe a DBPs monga trihalomethanes (THMs) ndi haloacetic acid (HAAs), zomwe zingathe kuyambitsa khansa. Izi zimathandizira chitetezo chonse komanso mtundu wamadzi akumwa.
7. Kuthira madzi a Sludge: Ferric chloride imagwiritsidwanso ntchito pochotsa matope m'malo opangira madzi oyipa. Zimathandiza kuti matope apangidwe mwa kulimbikitsa mapangidwe a magulu akuluakulu, okhwima, omwe amakhazikika mofulumira ndikutulutsa madzi bwino. Izi zimapangitsa kuti madzi azithira bwino komanso kuchepetsa kuchuluka kwa zinyalala, zomwe zimapangitsa kuti zikhale zosavuta komanso zotsika mtengo pogwira ndi kutaya matopewo.
Ferric Chloride imagwira ntchito yofunikira m'njira zosiyanasiyana zochizira madzi, kuphatikiza kuphatikizika, phosphorous ndi kuchotsa zitsulo zolemera, kuchotsa utoto ndi fungo, kusintha pH, kuwongolera tizilombo toyambitsa matenda, ndikuchotsa madzi amatope. Kusinthasintha kwake komanso kuchita bwino kumapangitsa kukhala mankhwala ofunikira pochiza madzi akumwa ndi madzi onyansa, zomwe zimathandiza kuonetsetsa kuti madzi ali otetezeka, abwino komanso osasunthika.
