The principle of wastewater purification, implemented in Toppa systems, is based on natural processing processes of organic matter by bacteria and microorganisms. It is known that anaerobic bacteria — bacteria, the life cycle of which, requires the presence of air oxygen, have greater activity and higher rate of biochemical reactions. That is why in Toppa septic tanks the natural process of processing organic substances by microorganisms is intensified by active air purge, which has a name — small -pussy aeration. Also, due to aeration, the wastewater mixing and additional oxidation of organic substances with oxygen, which prevents the decay of drains and the appearance of unpleasant odors.
