The values of the parameters that are the initial data for determining the required capacity of sludge tanks are adopted without sufficient scientific justification, which leads to significant discrepancies between the design and actual parameters of treatment facilities and the need to adjust the water treatment process. The object of the study is sludge tanks at developed placer deposits. The purpose of the study is to analyze the methods used to calculate the capacity of sludge tanks and to make recommendations for the justification of some components of the calculation formulas. Research objectives are as follows: to perform a systems analysis of the existing design methods for treatment facilities at placers and existing design solutions; to conduct field studies at placer gold mining sites; to identify the factors that have the greatest impact on the parameters of sludge tanks; to develop recommendations for adjusting the existing formula for determining the required capacity of a sludge tank. Research methodology and methods have become: analysis of traditional methods for calculating the required capacity of sludge tanks; comparison of the design and actual parameters of treatment facilities; conducting field studies with sampling of ephels and process water at operating facilities with subsequent laboratory testing, primarily of the granulometric composition of enrichment tailings and suspended particles in process water. As a result, based on a systems analysis, the main components of the formula used to determine the required capacity of sludge tanks have been identified, which are adopted without sufficient justification and can vary widely under different water treatment conditions; recommendations are developed for adjusting the formula for calculating the required capacity of sludge tanks and the accepted values of the initial data. The results of calculations using the proposed formula differ from the traditional one by up to ± 75 %, but generally correlate with the recommended values of the VNIII-1 Instruction and field research data. Therefore, taking into account the recommendations, the design value of the required capacity of sludge tanks will be more justified and it will have a positive effect on the quality of water treatment and performance of industrial devices.
