PRECAUTIONS
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.
This is especially true for the Multirock installations; considering the larger volumes of wastewater
to be treated, a proper dispatching through all Treatment Units is essential for efficiency of the
system.
It is the installer’s responsibility to ensure equal distribution of the wastewater by testing the Flow
Management System prior to leaving site. The installer should ensure any necessary supplementary
setting on the BIOROCK or non-BIOROCK Flow management System if necessary.
Important precautions for the proper use of the BIOROCK system: Only domestic sewage should enter
the system; no rainwater is allowed.
To ensure the good working order of the BIOROCK 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.
Do not dispose of the following items to the BIOROCK system:
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.
An effective effluent filter should be installed in the outlet of the Primary Tank, before the water
goes on to the Bioreactor.
Pipework after the ECOROCK units, and especially after Multirock installations, 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, 45
o
elbows should be used 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 with the
implementation, site and local conditions that may interfere in the system’s venting.
The Primary Tank should be aerated separately in accordance with the manufacturer's instructions.
