Main equipment used for water coagulation at thermal power plants

Abstract

Relevance: The current environmental situation in the world inevitably affects the quality of water needed in people's daily lives - both for domestic purposes and for industrial purposes, in particular in thermal power generation. According to calculations, 32-42 cubic meters of water are used to produce one gigawatt of electricity in thermal power plants, for example, from 6 thousand to 10 thousand cubic meters of water are consumed per hour to cool the turbine condenser of one of the power units of a thermal power plant.

Aim: Determination of the dependence of the coagulant dose on the composition of water using clarifiers designed by SNII-2 in water treatment at thermal power plants and shopping centers.

Methods: At thermal power plants, water purification to the required quality, depending on the profile of the enterprise, is carried out using mechanical, chemical, physicochemical, biological and thermal treatment methods.

Results: In our experiment, if FeSO4 salt is used as a coagulant, then to bring the pH of the water to an alkaline environment, using the formula Di = Dk – Ium + Iq, Table 1 shows how to obtain the dose of coagulant depending on the amount of organic and suspended matter in the water without adding a flocculant to the water.
