North American Great Lakes:
• Total population – 34 M
• 20% of global freshwater supply.
• Largest continuous freshwater mass.– Highly vulnerable:
– Spatial constraints.
– Urban/industrial centers.
– Shipping

Membrane Potable Water TreatmentMembrane Potable Water Treatment
• 20 decentralized treatment stations near Lake Michigan for freshwater withdrawal
• Tiered treatment train combining micro-, ultra-, and nanofiltration
• Achieves superior water quality by removing:
• Standard pathogens (E.Coli, giardia, cryptosporidium, viruses…)
• Colloids and nanoparticles
• Synthetic organic compounds including endocrine disrupting chemicals

• High turbidity from storms in Lake Michigan can clog membranes
• When sensors detect elevated turbidity:
• Cationic polymer coagulant added
• Coarse microfiltration system brought online
• Retentate and backwash flows discharged to wastewater treatment
UV
• Pathogen protection ensured through in-line UV stations located throughout distribution system
• Biochip sensors detect pathogen presence and activate UV
• UV LEDs provide high energy efficiency
• No chlorine residual required
• Avoids disinfection by-product formation
