And sulfur gas

Aerational station of deep biological cleaning — now is the most popular cleaning system. Because, unlike the septic tank, it does not accumulate pollution, but fulfills the full cleaning, and does not depend on the soil and the level of groundwater. The biological purification is that organic substances are destroyed by biochemical means, thanks to microorganisms, which in turn, these substances eat (their power source). It should be noted that after cleaning you will receive both purified water, which can be watered by the garden and organic fertilizer. In the process of cleaning, you will not feel unpleasant odors due to the fact that such harmful discharge as methane and sulfur gas is not formed. The only inconvenience of such a station may be that it depends on electricity.
