  1. Water Reclamation

  2. Overview • The concept: We provide an alternative source of water by harvesting and treating groundwater and/or capturing and treating process water • Why • Sustainable • Cost savings and rate hedging • Redundant water sources for business continuity

  3. Matching Uses

  4. Keys to Water Quality and Safety

  5. Proven Technology:Water Treatment Process Overview

  6. Proven Technology • Multi-Barrier Treatment Approach • Robust treatment • To treat the unexpected • Redundant systems • No single component will cause failure • Advanced real-time monitoring • Agreed testing protocol • Independent auditing/monitoring

  7. Recognized Standards • The following standards will be adhered to in both reuse and groundwater treatment: • 10 States Standards for Potable Water • EPA 2012 Guidelines for Water Reuse • ILSI – Water Recovery and Reuse: • Guideline for Safe Application of Water Conservation Methods in Beverage Production and Food Processing • Agreed water treatment and quality specifications

  10. Water Reclamation Treatment Effluent Treatment Overview Municipal Treatment

  11. Water Reclamation Treatment Equalization • Process wastewater will be pumped into an Equalization Tank where most of the solids will be ground up and removed; • Depending on the makeup of the water, chemicals (chlorine for example) will be added before the effluent enters the aerobic treatment tank;

  12. Water Reclamation Treatment Aerobic Digestion • Process wastewater treatment will consist of aerobic treatment using bacteria (activated sludge) oxygenated by blowers in the activation basin to degrade organic matter; • Microorganisms consume and remove the organics and nutrients from the water as solids; • During this process BOD (Biological Oxygen Demand) is significantly lowered; • Water will be tested and monitored after this process;

  13. Water Reclamation Treatment Membrane Bioreactor (MBR) • From the Activation Basin, water will be pumped into the Membrane Bioreactor (MBR), which is a common municipal wastewater treatment process; • MBR treatment will produce POTABLE water meeting all U.S. EPA standards that is suitable for most needs; • Water will be tested and monitored after this treatment;

  14. Water Reclamation Treatment Polishing • Nanofiltration membranes will be used to further treat the water beyond potable primary and secondary standards; • This potable water can be discharged free of contaminants (no surcharges) or be recycled for a variety of uses in the facility; • Water will be tested and monitored after nanofiltration;

  15. Water Reclamation Treatment Controls & Monitoring • Controls & monitoring systems will be installed for on- and off-site observation; • Reclaimed process water treatment will be tested at 5 different steps in the process; • Regular testing and third-party confirmation from EPA-certified labs shall be provided; • Water testing & monitoring will be more frequent and more stringent than by current provider;

  16. Water Reclamation Treatment High Service Pumping • Water will be delivered on demand by a high-service pumping system; • Redundancy will be built in so that potable water can always be provided; • Variable Frequency Drive pumps (VFDs) will be installed to ensure peak demands are met and energy is conserved in off-peak times;

  17. Water Reclamation Treatment Clearwell Storage • As with treated well water, treated effluent will be stored in a large clear-water underground tank for uses such as cooling, boiler make-up, steam, and cleaning; • Post-chlorination is provided to ensure water remains potable; • Water can be further adjusted and “customized” as needed;
