“…It should be noted, however, that such assumptions are true for filtration of a suspension containing fine quartz particles. In the case of filtration of clayey and similar suspensions, the physical and chemical factor of suspended solids adhesion to soil particles and then to settled solids appears [5][6][7][8][9][10].…”

Quarry wastewater is the main pollutant for the surface and underground natural water bodies during mining operations. Negative impact is expressed in contamination of natural reservoirs with fine suspended particles and salt solutions. To reduce the harmful impact of quarry wastewater they are treated using artificial filtering massifs. Such massifs are commonly constructed using artificial and natural sorbents. The retention of particles in the filtering layer is the result of two main processes: the adhesion of fine particles of suspension to the surface of the particles of the artificial filtering massif and the jamming of coarser particles in the pores of the filter layer. Simultaneously with the processes of contaminants capture, the process of contaminants washing out of the filter array may occur. It occurs when the particle size distribution of the filter layer is unappropriated and filtration speeds are high, and may be accompanied by deformation of the filter media.

Introduction. In the course of business activities of the enterprise (operational, investment and financial) relations with various individuals and legal entities emerge inevitably. They include suppliers and contractors, buyers, customers, banks etc. Accounts receivable arise in the course of these relationships. The issue of receivables is relevant and important for the organization of accounting of each enterprise, especially in the current business environment in Ukraine. Receivables affect the economic activity of any organization in such a way that receivables that are not closed for a long time (so the company has doubts about its return), respectively, first of all, worsen the financial condition of the company, and there is a deterioration in cash flow. Therefore, effective arrangement of settlements should directly help strengthen contractual discipline between contracting parties, increase the responsibility of the enterprise for the time period and fulfilling all payment obligations in full, accelerate cash flow, etc. The purpose of the paper is to analyze the issue of accounts receivable and their control, to develop proposals to improve accounting and monitoring accounts receivable, which will allow to improve their reflection and control in the future, without leading to the emergence of bad debts. Results. The article is devoted to the issue of accounts receivable, their accounting and control at enterprises, institutions, organizations of Ukraine. The theoretical and practical aspects of the interaction of the enterprise with the debtors and the emergence of the receivables were explored. Ways of improving the accounting and monitoring of accounts receivable were analyzed. Issues of controlling accounts receivable by activity of the enterprise were considered. Conclusion. Thus, receivables are an important component in the operation of any enterprise. Therefore, the organization of accounting receivables at enterprises of any ownership form contributes to the ordering of information; transparency, relevance and reliability of the data obtained with the settlements with debtors. It is important to anticipate and prevent an excessive increase in accounts receivable in advance because effective debt management is one of the prerequisites for successful business activity, since it creates the preconditions for rapid business growth and increased financial capacity of the company. The control over such accounts receivable, their systematic nature and periodicity are also important, improving the operation in terms of interaction with counterparties.
