FIELD: process engineering.
SUBSTANCE: set of invention relates to water treatment. Proposed station comprises electrolytic tank with anode and cathode chambers separated by membrane, sodium chloride solution preparation assembly, water feed line, batchers, separators of anolyte and catholyte and ejector arranged in flow line. Batchers are composed by proportioning pumps with external control. One of the latter is arranged in sodium chloride solution feed line to feed aid solution to anode chamber inlet while another one is arranged in that feeding water to cathode chamber inlet. Anolyte separator at anode chamber inlet is equipped with air bleed element with hydraulic lock at its inlet. Note here that outlet gas discharge pipe of the separator is communicated with ejector suction pipe. Catholyte separator is arranged at cathode chamber outlet and communicated with alkali accumulator. Besides this device comprises anolyte and catholyte separators and hydraulic lock integrated in single unit. Said unit is arranged in transparent case divided by baffles into three chambers, i.e. anolyte separator, hydraulic lock and catholyte separator. Case sidewalls are furnished with check marks to control fluid level in said three chambers.
EFFECT: higher safety and reliability.
