Mecana has been providing pile cloth media filtration in conjunction with rotating biological contactors (RBC) as a compact solution for over 50 years. Wastewater passes via gently rotating disks, which act as carrier material in Mecana RBC fixed-bed biofilm reactors. The revolving, partially submerged disks alternately supply oxygen and wastewater to the biofilm. This ideal carrier-fixed biomass source allows for effective nitrification and the efficient breakdown of organic materials with a very low energy need. Extra sludge is either separated by PCMF, which is usual for compact plants, or sedimented in a later stage. For capacities ranging from 50 to 30,000 PE, RBC plants are utilized.
How RBC functions
Mecana RBC are made up of a central shaft that has disk segments positioned on it that are around 2 mm thick and spaced distinctly apart. The individual disks, which range in diameter from 2.0 to 3.6 m (RBC) or from 1.2 to 2.0 m (MK), are constructed primarily from recycled polypropylene and are put together from six or eight segments. The system is set up in a concrete or steel basin. During operation, a drive on the center shaft rotates the disks, which are submerged 40–60% of the way in the effluent. This allows the biomass that has settled on the disks to come into touch with both the nutrient-rich wastewater and the necessary oxygen on an alternating basis. The biomass uses biological processes to break down the contaminants present in the wastewater.
