A Pilot Industrial Water Treatment Plant for the Primorskaya State District Power Plant Heating System

Abstract

Matters concerned with the development of a water treatment plant (WTP) for making up the heating system for the conditions of the Primorskaya State District Power Plant (operated by JSC Far East Generating Company) using a nanofiltration technology are considered. The WTP specific feature is that it uses nanofiltration to prepare water for making up an open-type heating network, which is the world’s first experience at an industrial level for such system. The use of nanofiltration makes it possible to obtain treated water of significantly better quality in terms of sanitary standards and rules in comparison with existing installations and ensure epidemiological safety of treated water. In addition, in comparison with the reverse osmosis technology, the use of nanofiltration features higher hydraulic efficiency and higher pH, due to which there is a reduced NaOH dose in treated water.
