Odour elimination – ozonation systems have been installed in two above ground sewage pumping stations in Rechytsa city, Belarus. Equipped ozonation systems ozonate the exhaust air ventilation. In it, polluted air mixes with ozone, ozone oxidizes odour molecules and odourless air is released into the environment. Both systems, like all Airplus1 technology systems, have remote monitoring, operation tracking, and ozone sensor data, which can be monitored in any web browser.
