Installation and User guide – ECOROCK - Systems – 26-05-2016
The Primary Tank should always discharge by gravity into the BIOROCK® system
Install the Primary Tank allowing a gradient towards the BIOROCK® system
The Primary Tank should be installed away from any traffic area, unless special precautions are in
place
The Primary Tank must be equipped with an efficient Effluent Filter
Installation of a Pump Well
If the effluent can’t be discharged by gravity, install a pump well & pump. The pump is
required to lift the effluent (purified water) to a higher level.
BIOROCK® has developed an optional PE pump well with a diameter of 400 mm.
The PE pump well has the same height as the ECOROCK unit.
All the connections are matching with the openings at the ECOROCK units.
At the end of the BIOROCK® Reactor the purified waste water (effluent) is collected in the
pump shaft and can be easily pumped to a higher level with a normal submersible pump.
The seals on the BIOROCK® tanks are flexible and have a diameter of 110 mm
The discharge pipe for the treated effluent should have a minimum gradient of 1%
4.1.3 Installation of the BIOROCK® treatment unit
The BIOROCK® unit must be installed downstream of the Primary Tank
The effluent from the Primary Tank should flow by gravity to the BIOROCK® unit
The gradient of the treated effluent pipe to the BIOROCK® unit should be a minimum of 1%
4.2 INSTALLATION IN DRY GROUND CONDITIONS
See Appendix «Installation in dry ground conditions»
Conditions for installation:
-
Dry and stable ground conditions
-
Absence of water at the bottom of the excavation
4.2.1 Installation and digging in dry ground conditions
The maximum level of top soil above the backfill is 200 mm
The units must stand on a clean and stable base such as concrete
In dry ground conditions pea gravel can be used
Mud and other soft materials must be removed from the bottom of the excavation prior to
installation
A stable base must be created at the bottom of the excavation
The base of the excavation should be level and compacted
There must be a distance of at least 300 mm between the walls of the excavation and the
units
