o Leveraging 15+ years of membrane research o Stable chemistry will not need aggressive hot water cleans to maintain performance
• High Solids Tolerance
o Ability to handle turbidity spikes up to 150 NTU and coagulant dose up to 40 mg/L
• Less chemical usage
o Lower OD fiber allows higher fiber packing density per shell volume o ~25 % less chemical volume in shell for same surface area
