Biofilm process

Fixed biofilm processes are used in the biological treatment of wastewater. Trickling filters are based on these processes.

• aerobic biofilm process for the degradation of organic substances and for nitrification
• transparent trickling filter with rotary distributor
• speed of the rotary distributor finely adjustable
• aeration of the trickling filter by natural convection or with compressor
• recording of concentration profiles is possible
• secondary clarifier with pump for transporting the return sludge
• all relevant flow rates finely adjustable
• separate supply unit with wastewater tank and two stirring machines
• two different carrier materials made of HDPE
