Biological rotors: What they are and how they work
Biological rotors, often commonly referred to as 'biodiscs' or 'biorolls,' are fundamental devices within wastewater treatment plants. These instruments play a key role in the secondary treatment of municipal and industrial wastewater through biological oxidation.
Biological oxidation processes
The process of biological oxidation of biodiscs is the equivalent of the percolator process. In fact, these biomass-adhered processes can be of two types: plants that use fixed supports, such as percolator beds, or plants that use mobile supports, such as biodisc processes and MBBR reactors.
Biomass-adhered processes involve the formation of a biological film that remains attached to the surface of the filters as it grows.Biomass-adhered processes do not require the recirculation of sludge to ensure the proper concentration of active sludge in the bioreactor.
Benefits of biological rotors
Biological rotors offer numerous advantages over other methods of wastewater treatment. Firstly, they are highly efficient and can reduce pollutant concentration in water up to 90%. Additionally, they require less space than other treatment systems and are more cost-effective to maintain.
Applications of biological rotors
Biological rotors are widely used in wastewater treatment systems worldwide. They are employed for the treatment of municipal and industrial wastewater, as well as for the purification of wastewater from agricultural and livestock activities.
Biological rotors represent an efficient, economical, and sustainable solution for wastewater treatment.
