Pofuna kuteteza chilengedwe, magnesium chloride imagwiritsidwa ntchito ngati choyeretsera madzi poyeretsa madzi otayidwa, ndipo ndikukhulupirira kuti makasitomala ambiri amadziwa izi. Choyeretsera madzi chimagwiritsa ntchito polyaluminum chloride, polyferric chloride, polyacrylamide ndi magnesium chloride ngati zopangira, chimawonjezera gawo lina la choyeretsera cha fluorescent ndikusakaniza mofanana muzinthu zopangidwa ndi granular, kenako chimapanga ma CD ambiri. Ubwino wa madzi, nthawi yochepa, mlingo wochepa, kuwola mosavuta, palibe poizoni wotsalira, palibe kuipitsa kwachiwiri, kuchotsa SS (zolimba zosungunuka), CODcr (kusowa kwa okosijeni wa mankhwala), BOD5 (kusowa kwa okosijeni wa biochemical) nayitrogeni yonse ndi phosphorous yonse ndizodziwikiratu, kodi Imapereka maziko abwino oyeretsera madzi ndi kuyeretsa madzi akumwa m'malo osiyanasiyana.
Kuyambitsa Magnesium Chloride:
Dzina la Mankhwala: Magnesium Chloride (MgCl2) Kufotokozera kwa Mankhwala: Dzina la Chingerezi ndi magnesium chloride. Fomula ya mankhwala ya MgCl2 imapangidwa ndi 74.54% chlorine ndi 25.48% magnesium, yokhala ndi molekyulu ya 95.21. Makristalo opanda utoto a hexagonal. Kuchulukana 2.316-2.33 magalamu/kiyubiki sentimita. Malo osungunuka 714 ℃. Malo otentha 1412 ℃. Nthawi zambiri amakhala ndi mamolekyu asanu ndi limodzi a madzi a kristalo, omwe ndi MgCl2 •6H2O, omwe ndi osavuta kuwachotsa, ndipo amataya madzi a kristalo chifukwa cha kuzizira mumlengalenga wouma. Ndi kristalo ya monoclinic yokhala ndi kukoma kwamchere komanso kuwononga kwina. Kuchuluka kwake ndi 1.569 g/cm3, malo osungunuka ndi 116-118℃, ndipo amawola nthawi yomweyo.
Mawonekedwe a magnesium chloride: nthawi zambiri amakhala opindika, otchinga, kristalo, granule ndi ufa. Zomwe zili mkati mwake ndi pafupifupi 46% magnesium chloride hexahydrate, ndipo 99% ndi magnesium chloride yosalowa madzi. Makhalidwe a magnesium chloride ndi thupi: amasungunuka m'madzi ndi ethanol. Zizindikiro za kumva: makristalo oyera, okhala ngati columnar kapena singano, okhala ndi kukoma kowawa. Fomula ya mankhwala MgCl2, kristalo wopanda mtundu, wosungunuka mosavuta m'madzi, wokhala ndi kukoma kowawa komanso mchere. Nthawi zambiri amakhala ndi madzi 6 a kristalo, kuchuluka kwa MgCl2 •6H2O ndi 1.56g/cm3, malo osungunuka ndi 118℃, ndipo amawola nthawi yomweyo. Magnesium chloride ndi chinthu chopangira kusungunula magnesium chitsulo ikatenthedwa, ndipo makamaka chimachokera ku mchere wa m'nyanja wouma ndi dzuwa.
