2.2 THE BIOROCK TREATMENT UNIT (Bioreactor) – ECOROCK
The ECOROCK sewage treatment units are biological purification systems, using the BIOROCK®
media as a carrier material for bacteria. An ECOROCK unit consists of two biological filtration
stages and one aeration stage, has pre-treated water passed through it by gravity. The pre-
treated water is spread over the surface of the first layer of BIOROCK® media by a distribution
system and penetrates into the media for purification.
The treated water discharging from the unit must flow by gravity to the next stage or a discharge
point.
