The BioCompact® P unit is placed at the bottom of an excavated hole then backfilled with sand or soil (installation of a BioCompact® P). After connecting the BioCompact® unit to influent and effluent pipes and to a source of electrical power, the system is ready for operation.

The aeration blower should be very close to the unit and in a small protective box or in an adjacent building. The control box should also be in an easily accessible place.

Ordinary maintenance includes regularly checking the activated sludge’s concentration. Sand, excess sludge, and non-degradable items (fibrous materials, plastic, rubber items, etc.) accumulate over time and must be removed periodically. The frequency of discarding this waste largely depends on the influent quality, and thus, on the habits of the population connected to the treatment system.
