› Reduced surface and groundwater supplies in many areas

› Inadequate local supplies and changing regional distr ibution

› Municipali t ies taking senior water r ights from long-standing industr ies

› Plants going idle or shutt ing down › More regulations driving up production

Water Sources

Thermal Desalination › Steam or hot water used to

effect ively boi l seawater

› Commercial Types: Mult i -Stage Flash Evaporat ion and Mult iple Effect Dist i l lat ion

Membrane Desalination Technology › Use of semi-permeable membranes

(Reverse Osmosis) to produce f resh water

› Commercial Types: Sea Water Reverse Osmosis (SWRO), Brackish Water RO (BWRO)

Wastewater Treatment

and Recycle Opportunities

› Cooling tower blowdown reuse

› Steam generator blowdown and condensate recovery

› Softener and filter backwashes

› Slurry line flush waters

› Storm water

› Reverse osmosis reject

Desalination Facility Optimization:

Develop A Water Management Plan

› Treat and recycle internal process wastewater

› Capture and treat storm waters

› Minimize water consumption/wastewater production

› Prevent contamination of water sources

Vulnerability & Resiliency

Assessment

+ Key metrics include changes in:

• Supply water quality

• Supply water availability

• Discharge limits

• Discharge volume

Other assessment metrics to consider:

• Sustainability

• Sustainable return on investment analysis (SROI)

Water Audit

• Perform site familiarization and permit review

• Identify water processes and confirm water flow diagram

• Evaluate water data and flow measurement to identify water saving opportunities

• Conduct sampling/testing

+

Process Integration

• Perform sources and sinks evaluation for improved process efficiency

• Conduct water pinch analysis and process evaluation for improved water-use efficiency reporting

+

Water Reuse or Recycling?

• Evaluate treatment options leading to process reuse

• Perform bench/pilot testing for technology prove out
