Methods of Water Purification at the Stage of Water Treatment for Feeding Boilers and Their Own Technological Needs at the Plant CHPP

Abstract

This work consists of the characteristics of production, assessment of the qualitative and quantitative composition of water, consideration of the process of water purification in the chemical shop, comparison and selection of coagulants and flocculants, and demonstration of the most affordable technology used at the CHPP which increases the efficiency of source water purification. The problem of pretreatment of the source water has always been relevant. The quality of the water used depends on the operation of boilers and turbines at the CHPP. The paper presents the average annual indicators of the quality of the source water, pre-treatment methods, and considers which reagents that do not require the cost of reconstruction of clarifiers can improve their performance. The initial water after the application of the test samples of coagulants and flocculants was studied. Conclusions are drawn about the work of clarifiers after the use of the proposed reagents.
