Experience gained from putting new technologies of water treatment in use at thermal power stations

New technologies of water treatment at heat power plants

“…In such schemes, further bringing the water quality up to the standard values is carried out by ion exchange (Fig. 2) or electroionite [3] ( Fig. 3) methods.…”

“…From the point of view of ensuring the minimum consumption of reagents and the highest environmental friendliness with the high quality of demineralized water, the most effective are complex WPUs, consisting exclusively of membrane modules for various purposes: ultra-and nano-filtration, reverse osmosis, membrane degassing and electrodeionization, called as a wholeintegrated membrane technologies (IMT) [3].…”

“…3), water is further purified at the electrodeionization unit. Electrodeionization (EDI) is a process of continuous desalination of water using ion exchange resins, ionselective membranes and a constant electric field [3]. The electrodeionization module contains two electrodes, the space between which is filled with thin layers of ionexchange resins, separated by ion-selective membranes.…”
