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
