Bioteg - Model MCBF-Series -Modular Container Air Biofilter System
Our Modular Container Biofilter Systems consist of one to four double walled filter containers to treat airflow rates in a range of 300 m3/h to 20.000 m3/h. The outer wall is made of steel with a treated and painted outer surface. The inner surfaces are coated with 4 mm heavy-duty polyethylene. For higher air flow rates we offer special tanks as biofilter containers. The plants of the series MCBF are of a rugged design and for an automatic operation mainly free of maintenance.
Typical applications: waste water treatment plants (WWTP), landfills, composting facilities, food industry, chemical industry etc.
Figure: MCBF-1000: suitable for 1000m3/h waste air and two stage operation. MCBF plants are delivered ready to use (turn-key) to the customer and are tested 24h non-stop before. This guarantees a proper function.
Waste air conditioning
Waste air is soaked through the cross stream scrubber by the radial ventilator. Water is re-circulated by a circulation pump. Loss of Water by evaporation is automatically refilled by means of electronic level sensors and by an electric valve. After being pre-cleaned and saturated with humidity, waste air is pushed through the biofilter beds, where micro-organisms metabolize organic and other odorous compounds. The humidifier (scrubber) can be opened easily for maintenance. The scrubbers water temperature is controlled by a sensor inside the scrubber. Setting and display of the scrubber temperature is done by the system control. So even at temperatures below 0°C a safe and stable operation is a matter of course.
Waste air cleaning
The radial fan soaks the preconditioned air stream from the scrubber into the biofilter-beds which are placed on grid elements inside the double-walled biofilter containers. As the air flows through the biologically active biofilter media inside the biofilter modules, the contaminants in the air stream are adsorbed into the water film surrounding the filter material, and are subsequently biologically degraded by microorganisms. The deodorised and decontaminated air is discharged to the atmosphere.
