Zomwe zidapangidwazo ndi zaukadaulo wopanga utoto wa utoto, ndipo makamaka zikugwirizana ndi flocculant ya utoto, njira yokonzekera ndikugwiritsa ntchito. The alipo utoto nkhungu flocculating wothandizila ali osauka flocculation zotsatira, COD kuchotsa, dzimbiri kupewa dzimbiri ndi kupewa dzimbiri zotsatira, kotero kutulukira amapereka utoto nkhungu flocculating wothandizira, umene uli zotsatirazi zopangira A wothandizila ndi B wothandizira; The A wothandizila limapangidwa, ndi kulemera, 1-5 mbali ya amino pawiri, 1-5 mbali aldehyde pawiri, 30-60 mbali bentonite ndi 10-20 mbali polyaluminium kolorayidi; wothandizila B limapangidwa 0.5-1.5 mbali polyacrylamide, 0,3-1 mbali ya bactericide, 20-40 mbali ya antirust zowonjezera ndi 2-6 mbali defoamer; wothandizira A ndi B onse ali ndi magawo 300 a madzi. Kupangaku kumaperekanso njira yokonzekera ndikugwiritsa ntchito chothandizira chowongolera utoto. The flocculant ntchito kwa utoto nkhungu kuchotsa mlingo mu madzi oipa, amene ndi oposa 95%, akhoza kuchepetsa SS olimba inaimitsidwa nkhani, imodzi kuchepetsa COD ndi oposa 55%, ndipo akhoza ankagwiritsa ntchito pochiza utoto mu madzi oipa.
