  • Mem-TAD: Membrane Thickened Aerobic Digestion

    A Membrane Thickened Aerobic Digester (Mem-TAD) process is a controlled aerobic digestion system that utilizes a flat sheet membrane thickener. It is an excellent solids handling solution for plants requiring Class B compliance with minimal footprint and energy usage but also want to protect a BNR liquid treatment process from excessive nitrogen and phosphorus in side stream flow.
