Watertight sand filter

The watertight sand filter is a wastewater treatment system whose design is based on the replacement of the natural soil layer by a
filtering media. The sand filter unit combined with a phosphorus removal unit (DpEC) provides an efficient solution for phosphorus
removal and for disinfection.
At the phosphorus removal unit (DpEC) effluent, the wastewater is directed to the watertight sand filter by a pumping station to feed the
distribution device. The water percolates vertically through the sand bed and then collected by a network of perforated pipes located
on the gravel bed at the base of the watertight sand filter.
The sand filter allows continuous or intermittent use without requiring any special precautions and without any impact on the quality of
the treatment. The owner has no particular action to make to bring the system into operation; the owner only needs to ensure
compliance with the operating instructions described below.

Triggering system start-up

The start-up of the phosphorus removal unit (DpEC) (i.e. the electrification of the Electrodes and Agitating Pump) can be performed
two ways. However, two simultaneous conditions must be taken into consideration. Should one of these two conditions not be met,
the system will not start. The device will also detect the presence of incoming wastewater.
