Important factors of MBBR technology for wastewater treatment

Initially, the complete task to be performed in the project should be specified. Apart from the space conditions and requirements on site, a detailed examination of the wastewater influent parameters and of the treated effluent quality is required.

The size of the MBBR/IFAS tanks and the related carrier media filling rate are determined based on the pollutant loads and in consideration of specific product factors of the carrier media. Here, the loads are calculated from the flow rate (m3/h or m3/d) and the respective pollutant concentrations, e.g. COD (mg/l). Crucial factors for the dimensioning of MBBR/IFAS plants are the wastewater temperature at the design point, the yield and product specific removal rates (removal efficiency) of the carrier media chosen.
