•  What is the minimum space to be allotted for the home sewage treatment plant?

Assuming that the lot is on permeable ground and a diffusing drainage system can be used, the minimum area for the sewage treatment plan (for a four-person family) will be approx. 50 m2.
If the lot is small, and a receiving body of water like a land melioration ditch, a river or rainwater drainage system, a solution incorporating a biofilter can be used. In this case, approx. 7m2 will have to be used for the construction of the sewage treatment plant.

•  What should be done to secure the tank for the winter if the sewage treatment plant was fitted in autumn and the start up is to take place in spring?

All septic settling tanks manufactured by the Sotralentz company are frost proof. Owing to this, there is no risk of the tank being damaged even when temperatures are extremely low. It is necessary to remember that the settling tank should be filed with water and bioactivators should be used before starting to use the tank.

•  What is the influence of bioactivators on the sewage treatment plant?

Bioactivators aid the natural processes of biological decomposition of pollutants which take place in septic settling tanks; they fluidize solid residue, remove unpleasant smell, destroy the pathogenic bacteria, and resolve fats.
