Iyo yakagadzirwa ndeye tekinoroji yependi mhute flocculant kugadzirwa, uye kunyanya ine chekuita nemhute yependi inoyerera, nzira yekugadzirira uye kushandiswa kwayo. Iyo iripo pendi mhute inoyerera mumiriri ine yakashata flocculation mhedzisiro, COD kubviswa, kudzivirira ngura nekudzivirira ngura, saka kugadzirwa kunopa pendi mhute inoyerera mumiririri, iyo inosanganisira inotevera mbishi zvinhu zveA agent uye B agent; iyo A agent inoumbwa, nekurema, 1-5 zvikamu zveamino compound, 1-5 zvikamu zvealdehyde compound, 30-60 zvikamu zve bentonite uye 10-20 zvikamu zve polyaluminium chloride; iyo mumiririri B inosanganisira 0.5-1.5 zvikamu zve polyacrylamide, 0.3-1 chikamu chebhaktericide, 20-40 zvikamu zve antirust additive uye 2-6 zvikamu zve defoamer; mumiririri A uye mumiririri B ose anosanganisira zvikamu mazana matatu emvura. Iyo yakagadzirwa inopawo nzira yekugadzirira uye kushandiswa kwependi mhute flocculating agent. Iyo flocculant inoshandiswa kune pendi mhute kubviswa mwero mumvura yetsvina, iyo inopfuura 95%, inogona kuderedza SS yakasimba yakamiswa nyaya, panguva imwe chete ichideredza COD neanopfuura 55%, uye inogona kushandiswa zvakanyanya kurapa pendi mumvura yetsvina.
