Zitsulo zolemera ndi gulu la kufufuza zinthu monga zitsulo ndi metalloids monga arsenic, cadmium, chromium, cobalt, mkuwa, chitsulo, lead, manganese, mercury, faifi tambala, tini ndi nthaka. Ma ion zitsulo amadziwika kuti amawononga nthaka, mlengalenga ndi machitidwe a madzi ndipo ndi poizoni ngakhale pamagulu otsika kwambiri.
Pali magwero awiri akuluakulu azitsulo zolemera m'madzi, magwero achilengedwe ndi magwero a anthropogenic. Zinthu zachilengedwe zimaphatikizapo kuphulika kwa mapiri, kukokoloka kwa nthaka, zochitika zamoyo, ndi nyengo ya miyala ndi mchere, pamene magwero a anthropogenic amaphatikizapo kutayira, kuwotcha mafuta, kusefukira kwa mseu, zimbudzi, ntchito zaulimi, migodi, ndi zowononga mafakitale monga utoto wa nsalu. Zitsulo zolemera zimatchedwa poizoni ndi carcinogenic, zimatha kudziunjikira mu minofu ndikuyambitsa matenda ndi zovuta.
Kuchotsa ma ion a heavy metal m’madzi oipa n’kofunika poyeretsa chilengedwe ndi thanzi la anthu. Pali njira zingapo zomwe zafotokozedweratu zoperekedwa pakuchotsa ma ayoni azitsulo zolemera kuchokera kumagwero osiyanasiyana amadzi oyipa. Njirazi zitha kugawidwa mu adsorption, membrane, chemical, electro, and photocatalytic based treatments.
Kampani yathu ikhoza kuperekaHeavy Metal Chotsani Wothandizira, Heavy Metal Remove Agent CW-15 ndi chowotcha chopanda poizoni komanso chokomera chilengedwe. Mankhwalawa amatha kupanga chitsulo chokhazikika chokhala ndi ma ion achitsulo amphamvu kwambiri komanso osakanikirana m'madzi oipa, monga:Fe2+,Ni2+,Pb2+,Cu2+,Ag+,Zn2+,Cd2+,Hg2+,Ti+ndi Cr3+, kenako nkufika cholinga chochotsa maganizo olemetsa m'madzi. Pambuyo pa chithandizo, Mpweya sungathe kusungunuka ndi mvula, palibe vuto lina lililonse lakuyipitsa.
Ubwino wake ndi awa:
1. Chitetezo chachikulu. Non-poizoni, palibe fungo loipa, palibe poizoni opangidwa pambuyo mankhwala.
2. Good kuchotsa zotsatira. Itha kugwiritsidwa ntchito mumitundu yonse ya pH, imatha kugwiritsidwa ntchito mumadzi amchere kapena amchere amchere. Pamene ayoni achitsulo amakhala pamodzi, amatha kuchotsedwa nthawi imodzi. Pamene ayoni olemera kwambiri ali mumchere wovuta (EDTA, tetramine etc) womwe sungathe kuchotsedwa kwathunthu ndi njira ya hydroxide precipitate, mankhwalawa akhoza kuchotsanso. Ikayimitsa chitsulo cholemera, sichingatsekerezedwe mosavuta ndi mchere womwe umakhala m'madzi otayidwa.
3. Good flocculation zotsatira. Kupatukana kolimba-kwamadzimadzi mosavuta.
4.Heavy metal sediments imakhala yokhazikika, ngakhale pa 200-250 ℃ kapena kuchepetsa asidi.
5. Njira yosavuta yopangira, kuchotsa madzi amatope mosavuta.
Ngati mumakonda malonda athu, kulandila kukambilana. Tikukutumikiranibe pa Chikondwerero cha Masika.
