1.3 PRECAUTIONS
Important precautions for the proper use of the MONOBLOCK system:
Please note that BIOROCK shall not be responsible for any installation design parameters and
groundworks at any case. We recommend to involve a civil engineer or a specialized design office
in the design of the system installation if necessary and to follow best practices of the industry.
Only domestic sewage should enter the system; no rainwater is allowed.
To ensure the good working order of the MONOBLOCK system, the use of automatic toilet cleaners,
electric waste-disposal systems and pumps equipped with blades are not to be used. If there is a
professional kitchen on site, an efficient and properly sized grease trap should be installed. The
grease trap should be installed before the primary tank.
The MONOBLOCK is equipped with an effective effluent filter at the outlet of the Primary
compartment before the water goes on to the secondary compartment. However, do not dispose of
the following items to the MONOBLOCK system as it may affect the treatment process:
Kitchen or motor oils, fats, wax, resin, paint, solvents, hydrocarbon-based products (petrol, crude oil
etc.), any pesticide or antibacterial product, items of a toxic nature, boiler or air-conditioning
condensate, swimming pool backwash, rainwater, drainage water or ground-water.
We recommend that pipework after the MONOBLOCK unit should allow sampling.
Special care should be taken with the aeration of the system. The aeration should be checked by the
installer using a smoke test once pipework and ventilation ducts have been connected and before
backfilling the system. The smoke test should be performed under normal representative conditions.
Each system should be vented independently and equipped with its own ventilator (wind driven or
electrical). The number of elbows used in the pipework should be limited as much as possible. 90
o
elbows should not be used but 45
o
elbows instead. The high air outlets should be installed as close
as possible to the low air inlets.
Achieving efficient ventilation is the responsibility of the installer as he is familiar to the
implementation site and local conditions that may interfere in the system’s venting.
