- Model MPHR - Biomedia System



Global Mold’s Multi-Pollutant, High Rate Biomedia (MPHR Biomedia). MPHR is designed as a suspended media for improving the performance of activated sludge wastewater treatment plants (WWTP). It offers all the benefits of IFAS systems, without any of the disadvantages of fixed media. Its unique design consists of a high impact resistant, high surface area plastic extruded media, which surrounds a high surface area open-cell foam/ceramic. This media has and applied bacterial population adhering to the plastic surface, which is very open to prevent clogging, with an anoxic, de-nitrifying zone within the open cell foam/ceramic piece. As with all of our products, Global MPHR designed media is uniquely engineered to provide maximum surface contact while insuring uniform liquid distribution throughout the media.
