Zitsulo zolemera ndi gulu la zinthu zochepa zomwe zimaphatikizapo zitsulo ndi zitsulo monga arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, mercury, nickel, tin ndi zinc. Ma ayoni achitsulo amadziwika kuti amawononga nthaka, mlengalenga ndi machitidwe amadzi ndipo ndi oopsa ngakhale atakhala ochepa kwambiri.
Pali magwero awiri akuluakulu a zitsulo zolemera m'madzi, magwero achilengedwe ndi magwero obadwa ndi anthu. Magwero achilengedwe ndi monga kuphulika kwa mapiri, kukokoloka kwa nthaka, zochitika zamoyo, ndi kuwononga miyala ndi mchere, pomwe magwero obadwa ndi anthu ndi monga malo otayira zinyalala, kuyatsa mafuta, madzi otuluka m'misewu, zimbudzi, ntchito zaulimi, migodi, ndi zoipitsa m'mafakitale monga utoto wa nsalu. Zitsulo zolemera zimagawidwa m'magulu a poizoni komanso khansa, zimatha kusonkhana m'maselo ndikuyambitsa matenda ndi zovuta.
Kuchotsa ma ayoni achitsulo cholemera m'madzi otayira n'kofunika kwambiri poyeretsa chilengedwe ndi thanzi la anthu. Pali njira zosiyanasiyana zomwe zanenedwa kuti zimagwiritsidwa ntchito pochotsa ma ayoni achitsulo cholemera m'madzi otayira osiyanasiyana. Njirazi zitha kugawidwa m'magulu awiri: mankhwala opangidwa ndi ma adsorption, membrane, chemical, electro, ndi photocatalytic.
Kampani yathu ikhoza kuperekaChotsukira Cholemera Chochotsa Wothandizira, Heavy Metal Remove Agent CW-15 ndi chogwirira cha heavy metal chopanda poizoni komanso chosawononga chilengedwe. Mankhwalawa amatha kupanga mankhwala okhazikika okhala ndi ma ayoni ambiri achitsulo a monovalent ndi divalent m'madzi otayidwa, monga: Fe2+, Ni2+, Pb2+, Cu2+, Ag+, Zn2+, Cd2+, Hg2+, Ti+ ndi Cr3+, kenako n’kufika pochotsa ubongo wolemera m’madzi. Pambuyo pochiza, Mvula singathe kusungunuka ndi mvula, palibe vuto lina lachiwiri la kuipitsa.
Ubwino wake ndi uwu:
1. Chitetezo chapamwamba. Chosakhala ndi poizoni, chopanda fungo loipa, chopanda poizoni wopangidwa mutalandira chithandizo.
2. Kuchotsa bwino. Itha kugwiritsidwa ntchito pa pH yochuluka, ingagwiritsidwe ntchito m'madzi otayira acid kapena alkaline. Ma ayoni achitsulo akamakhala pamodzi, amatha kuchotsedwa nthawi imodzi. Ma ayoni achitsulo cholemera akamakhala mu mawonekedwe a mchere wovuta (EDTA, tetramine etc) womwe sungachotsedwe kwathunthu pogwiritsa ntchito njira ya hydroxide precipitate, mankhwalawa amathanso kuchotsedwa. Ikatulutsa chitsulo cholemera, sichidzatsekedwa mosavuta ndi mchere wokhazikika m'madzi otayira.
3. Kutulutsa madzi bwino. Kusiyanitsa madzi olimba mosavuta.
4. Madontho achitsulo olemera ndi okhazikika, ngakhale pa 200-250℃ kapena asidi wochepa.
5. Njira yosavuta yogwiritsira ntchito, kuchotsa madzi ochulukirapo mosavuta.
Ngati mukufuna zinthu zathu, Takulandirani kuti mukambiraneTikutumikirabe inu pa Chikondwerero cha Masika.
