Percolation purification, which is also known as sub-irrigation, represents one of the widely used systems.
The process is based on the regular top-to-bottom distribution of wastewater in the so-called 'percolation bed' made of many layers of draining material (such as stones, plastic materials, etc.) that permits the reproduction of the same microbiological environment that can already be found in nature.
This type of system, principally effective in raised percolation beds, can be used to dispose domestic wastewater through sub-irrigation following primary treatment.
This is the ideal solution for residential areas that are not connected to the sewage system.
Thanks to its large infiltration surface, DRENING guarantees a fast and uniform infiltration in the subsoil.
Moreover, the septic tank construction can be designed with few ventilation ducts, installed in order to prevent bad smells and to return cleaner water to the environment.
Besides, the system is easy to clean and to inspect in comparison with the micro-perforated pipe that is traditionally used.
Our system main advantages are:
DISPERSION: DRENING has a bigger permeable surface in comparison with the micro-perforated pipe, so it guarantees a more uniform infiltration in the subsoil and a high-result percolation purification
INSPECTIONABLE: the system is very easy to inspect and clean
VENTILATION: DRENING wide section allows a great ventilation from the outside for a better biological purification process
ECO-FRIENDLY: the system has a low impact both on the environment and on the living comfort
