The unit is placed on a compacted, leveled sand bed at the bottom of the excavated hole. After connecting the BioCompact® to the influent and effluent pipes, and to an electrical power source, the system is ready for operation.

The aeration blower should be located in very close proximity to the unit, and installed in a small protective box, or an adjacent building. The control box should also be located in a place which is easily accessible, in order to verify on a regular basis that the green light is on, indicating that the system is operating satisfactorily.


Ordinary maintenance includes a bimonthly check of the concentration of activated sludge, a monthly check for verification of proper operation of sensors and their cleaning. Non-degradable items (fibrous materials, plastic, rubber items, etc.), sand, and the digested excess sludge accumulated over time and must be removed periodically. The frequency of discarding this waste depends largely on the influent wastewater quality, and thus on the habits of the population connected to the treatment system.
