2.2 THE ECOROCK TREATMENT UNIT (Bioreactor)
The well-proven BIOROCK biological purification process takes place in the ECOROCK Treatment Unit.
The BIOROCK media is used as a carrier material allowing growth of the necessary bacteria (biomass),
a process which is essential for the effective treatment of domestic wastewater.
The ECOROCK-700 to 900 consists of three biological filtration stages and one aeration stage.
(See
Appendice 1.6 : Détail of BIOROCK media layer)
The pre-treated water is spread over the surface of the first layer of BIOROCK media by an effluent
distribution system and penetrates into the media for purification.
The effluent flows via gravity through a ventilated area, mixing oxygen with the effluent prior to
the secondary filter stage. Efficient ventilation throughout the treatment plant is essential for
maximized performance.
A second section of the compartment contains a second media bed providing further
treatment
Finally, the lower section of the tank contains a third media bed providing final treatment.
See Ch. B/3.2 for weight details of each BIOROCK media layer
The treated water discharging from the unit must flow by gravity to the next stage or a discharge point.
Avoid stagnant treated effluent at the discharge point. Make sure the discharge pipe is equipped to
avoid small animals entering the system.
Each ECOROCK Treatment Unit should be vented independently and equipped with its own ventilator
(wind driven or electrical if necessary).
(See appendix 2.1: Ventilation scheme).
