• Cost effective UF membrane quality effluent
• 50% lower energy consumption than an MBR
• 50% less membrane area than an MBR 
• No air scour required
• No ultra fine prescreening required
• Reduced footprint

IMAS achieves the fundamental dual goals of minimizing both membrane area and energy consumption while producing membrane quality effluent.  This is accomplished by dramatically lowering the membrane fouling rate by managing the composition and concentration of particles which contact the membrane surface.

The low fouling nature of IMAS generated suspended particles allows the transmembrane pressure drop to remain consistently low, even when challenged with high peak flow periods and varying influent turbidities. Although the membrane influent turbidity can vary significantly, the membrane permeate turbidity consistently remains less than 0.1 NTU.  The design and operation of IMAS technology creates a complimentary synergy between the biological and membrane processes, allowing for the highest total system efficiency to be achieved, while maintaining a compact footprint and generating minimum waste sludge.
