MOBED - Wastewater Treatment With Pure Moving Bed Reactor
Wastewater treatment with pure moving bed reactor (MBBR) configuration, where both nitrification and denitrification occur in the biofilm. It consists onthe introduction of our MOBED® moving bed into the tank on which the biofilm grows for the removal of organic matter and nitrogen. 20-60% of the reactor volume can be filled with moving bed. The solution requires separate biological reactors and a subsequent secondary decanter without sludge return for solids separation.
Organic matter removal
Munici: Municipal: Suitable for small populations without nitrogen requirements, such as the project implemented in Riumar.
Iindustrial: Very efficient treatment because the organic matter is mostly soluble and in high concentrations. In cases of very high concentrations, the treatment capacity can be increased as hybrid processes can occur by detaching part of the biofilm and working partially in suspension. The food industry plant executed is a good example of this solution.
Removal of organic matter and nitrogen
Municipal: Optimal solution for medium nitrogen removal requirements, due to the high nitrification capacity of the biofilm. If high nitrogen removal rates are required, an IFAS solution or dosing can be chosen.
Industrial: Optimal solution for both medium and high nitrogen removal requirements, as the presence of BOD is usually higher and dosing can be avoided.
Phosphorous removal
In pure MBBRs, phosphorus removal is always done by the addition of chemical reagents, as it is not possible to do this biologically.
