CE 701 Biofilm process

GUNT CE 701

Biofilm Process unit is designed for the aerobic biofilm process, enabling the degradation of organic substances and nitrification. It features a transparent trickling filter with a finely adjustable rotary distributor for precise control of biofilm growth. The trickling filter can be aerated via natural convection or with an integrated compressor. The system includes a secondary clarifier with a return sludge pump and a wastewater supply unit with a stirring system. The flow rates of all key components are adjustable. The unit is equipped with two different HDPE carrier materials, allowing for comparative studies.
