biorock – waste water treatment in trade fair – accra

The BIOROCK complete system functions as a three-stages treatment process.

Initially the raw sewage enters a primary tank to provide separation and the breakdown of organic solids (Primary Treatment). The sewage then passes through an effluent filter before discharging into the BIOROCK unit which incorporates the well proven aerobic digestion process (Secondary Treatment) and filtration process (Tertiary Treatment).

BIOROCK mission is to provide economical and ecological solutions to sewage treatment problems, offering the best service and quality products to our customers. The BIOROCK systems discharge purified effluent of exceptional quality, much higher than the national standards, allowing in most cases immediate release to surface waters such as rivers and ponds, subject of course to local and national regulations in each country.
