Makampani adzatulutsa madzi ochulukirapo ambiri, madzi otayira okhala ndi mafuta, zolimba zoyimitsidwa, zitsulo zolemera, ndi zinthu zina zovulaza ndi thovu, kutulutsa mwachindunji kudzaipitsa malo ozungulira. Bungwe la Environmental Monitoring Bureau lili ndi zofunika kwambiri pakuwongolera zimbudzi komanso kuyezetsa mwamphamvu. Njira yopangira madzi oyipa ndiyovuta, ndipo ndikosavuta kukumana ndi zovuta za thovu pochiza.

Chimbudzi mankhwala malinga ndi mlingo wa magawano, ogaŵikana mmodzi, awiri, atatu madzi mankhwala. Komabe, chifukwa cha ndondomeko ya mankhwala ndi khalidwe la zimbudzi, ndondomeko ya kuchimbudzi ndi yosavuta kuwira, ndicho kufunika ntchito zimbudzi mankhwala defoamer kwa defoaming.

Chimbudzi mankhwala kaya thovu chifukwa madzi zigawo zikuluzikulu, kapena thovu chifukwa cha mankhwala ndondomeko. Osati chithandizo cha nthawi yake chidzakhala ndi zotsatira zoipa pa dongosolo la mankhwala, zomwe zimakhudza kutulutsa madzi abwino. Pofuna kuthetsa vuto la chithovu mu zimbudzi, kuwonjezera defoamer ndi njira yabwino.
Malinga ndi mawonekedwe aukadaulo wochotsa zimbudzi ndi mtundu wamadzi, defoamer yachimbudzi yopangidwa ndi njira yokhazikika ya defoamer yopangidwa ndi polyether ndi silikoni. Defoamer imapangidwa ndi akatswiri opanga ma defoamer, ali ndi ntchito yabwino, ndipo amatha kuthana ndi zovuta zosiyanasiyana za thovu poyeretsa zimbudzi. Defoamer iyi imapangidwa ndi zida zapamwamba kwambiri, mawonekedwe ake amakhala okwera kwambiri, ndipo amatha kuwonjezeredwa mwachindunji pakuchotsa zimbudzi. Zochepa zokha ndizofunika kuti mukwaniritse zotsatira zabwino za defoaming. Malinga ndi machitidwe osiyanasiyana a thovu ndi kuchuluka kwa thovu, kuchuluka kwake kumawonjezeredwa ngati koyenera; Mukamagwiritsa ntchito, gwiritsani ntchito madzi okwanira 1 mpaka 5 kuti muwonjezere kapena kuwonjezera mwachindunji (zosavuta kuziyika pambuyo pa kuchepetsedwa, zomwe zimayenera kugwiritsidwa ntchito mwamsanga), mukhoza kufunsanso wopanga kuti agwiritse ntchito.
