The Etch2o’s MBBR system is an innovative biological treatment process using thousands of special carriers designed to create an enormous total surface area for biofilm growth – enhancing your wastewater treatment process without expanding your footprint.In the MBBR configuration offers a treatment process based on a bio-film which provides organic carbon removal, as well as nitrification and de-nitrification where needed, without circulation of activated sludge. The process is simple, robust, and requires minimal operator intervention. Wastewater is introduced into a single or multiple-stage system (depending on whether Nitrogen removal is required), each of which contains the suitable volume of biomass carriers.

The MBBR configuration is extremely well suited for a wide range of applications: from pre-treatment of industrial wastewater, to full treatment of municipal wastewater to the most stringent effluent requirements.
