Assessing the efficiency of water reuse at Khorostkiv sugar factory

Pavlo Skorokhod Oksana Mayevska

The Ukrainian sugar industry applies large amounts of water for production needs but is not sufficiently focused on the optimal use of water resources. The aim of this study was to evaluate the effectiveness of reusing condensate and cooling water to optimise water resource use and reduce the volume of water intake from surface water bodies. Based on the data from official reports of the Khorostkiv Sugar Factory in 2017-2024 years an analysis of the water use changes after improvement of the circulating-water system was conducted. In particular, a statistical method was used to calculate changes in water intake and the water recycling coefficient, as well as to conduct an environmental and economic assessment. It has been found that the total water intake since 2019 has decreased by approximately 8.1-21.3 times (2019-2024) compared to the value calculated for 2017. It has been shown that the water use process has been optimised through the functioning of a modern recycling system with the effective use of condensate and cooling water. It was emphasised that such optimisation led to the termination of discharge of heat-exchange wastewater into surface water bodies. It was estimated that the economic effect of reusing cooling and condensate water only for a rental fee led to a reduction in the company’s annual financial costs of approximately 350-400 thousand hryvnias. The practice of reusing cooling water and condensate water can be recommended for use at other Ukrainian sugar enterprises
