The paper presents the results of a study of factors affecting the efficiency of water treatment from heavy metals with dust from bag filters from Belgorod, ZhBI-4. The dynamics of the amount of dust formation of bag filters is given in the paper. The granulometric and phase composition of dust is investigated. A description of the processes occurring when adding dust to the aquatic medium is presented. The effect of dust mass on the pH of the aquatic medium is studied. It was established that this dust can be used as an adsorbent for the waste water treatment from heavy metal ions. High efficiency of wastewater treatment with dust of plant "ZhBI-4" is proved. It is shown that with an increase in the mass of the BFD additive to 0.5 g per 100 dm3, the purification efficiency smoothly rises to 99.9% with the mass of BFD 0.5 g for Sorig = 20 mg / dm3 and 95.3% for Sorig = 10 mg / dm3 The nature of the curve, which reflects the dependence of the PH of the medium on the mass of BFD, is similar to the shape of the curve, which reflects the dependence of the pH of the medium on the mass of the BFD, which emphasizes the effect of the pH of the aqueous medium on the process of formation of Cu (OH)2 precipitate. However, at the same time, it should be noted that the process of treatment from Cu2+ ions also takes place in the range of lower pH values, which exclude the possibility of formation of Cu(OH)2 precipitate. Therefore, treatment can occur due to the adsorption of Cu2 + ions and their hydrolysis products [CuOH] + on the surface of the BFD.
