wastewater treatment in two steps
The compact x-perco® filter works by percolation. This simple, cost-effective process is driven by gravity in two phases: primary decanting and filtering via the xylit filter media. Xylit consists of natural wood fibres derived from lignite. It has a minimum life span of 10 years, can be composted according to the French NF U44-095 standard, and has a low ecological impact.

first step: decantation
The x-perco® consists of two compartments. The wastewater enters this compartment, called the primary decanter. It is pre-treated to detach solids.

second step: reaction
The pre-treated wastewater is then spread evenly over the filter media by a small rotating device: the aquacan. This distribution system was developed and patented by eloy water. The wastewater percolates through the xylit filter and is naturally treated without energy, then evacuated.
