Drainage treatment plant

The on-site sewage treatment plant — drainage treatment plant with infiltration system is designed to treat domestic sewage in areas without sewers, and it is successful in replacing concrete septic tanks. The essence of infiltration drainage is the system of underground land drains, introducing pre-treated sewage into the soil for further biological treatment. Drains enable the sewage to infiltrate into the soil over a large surface leading to its further treatment by the bacteria in the soil. It is treated by biological sorption, the retention of chemical ingredients aided by soil microbes and plant root systems.

Treatment plant operating processes
Sewage treatment in drainage treatment plants can be compared to the processes occurring in nature, and it occurs in two consecutive processes:

1. Pre-treatment, which occurs in the drainage treatment plant through the processes of decanting (separation) and fermentation of the sludge aided by anaerobic bacteria, which results in partial sewage liquefaction. After passing the filter, pre-treated sewage is routed through the distribution well into the infiltration deposit. In the deposit, the sewage is treated as a result of biological and chemical aerobic processes.
2. Infiltration drainage is the second stage of the aerobic sewage treatment. Made of tunnels, it enables the installation of the treatment plant in a small area and a significant reduction of project labour intensity. The suitable design of drainage tunnels provides proper aeration of the sewage, which is necessary for the growth of the biological film, responsible for proper sewage treatment.

Sewage parameters after both processes meet Polish and EU regulations.

Our range includes all kinds of tank top extensions, expansion telescopes, covers, distribution wells, control units, drainage pipes, infiltration tunnels and filters for treatment plants.
