THE BIOROCK® SEWAGE TREATMENT PLANT
1.1
GENERAL POINTS
The ECOROCK SYSTEMS from BIOROCK are compact non-electric Sewage Treatment Plants. The
treatment relies on the revolutionary BIOROCK® biological purification process. The ECOROCK
sewage treatment unit is exclusively designed for domestic waste water purification.
The BIOROCK® plant consists of a Primary Tank and a ECOROCK Bioreactor. Both parts (Primary Tank
and Bioreactor) must be ventilated.
A small pump can be installed in a pump shaft downstream of the system to lift the treated water
and discharge to a higher level if needed.
BIOROCK® recommends the installation of an effluent sampling at the outlet of the treatment unit.
The ECOROCK treatment unit can be installed (retrofitted) after a non-BIOROCK Primary Tank,
provided that this tank is properly sized, equipped with an efficient effluent filter and properly
vented.
1.2 SIZING
The ECOROCK units have a capacity of 6, 10, 15 and 30 P.E. (Person Equivalent). This manual is
for the ECOROCK-1500, 3000. The capacity of the individual ECOROCK unit can be increased if
the required final effluent quality is of a lower standard than the results, achieved during the
EN-12566-3 Performance test
.
1.3 PRECAUTIONS
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, a 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.
We recommend that every ECOROCK unit should be equipped with a sampling pipe.
Special care should be taken with the aeration of the system. The aeration should be checked by the
installer with a smoke test. The smoke test should be performed under normal representative
conditions.
Each unit should be vented independently and equipped with its own ventilator (wind driven or
electrical). Limit the number of elbows used (never use 90
o
elbows, only use 45
o
elbows).
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. The installer understands the local
conditions.
The Primary Tank should de-aerated separately in accordance with the manufacturer's instructions.
