  3. Company Overview Depth Filters • Provide water treatment products for businesses and homes • Depth Filters • Membranes • RO Systems RO System Membrane

  4. Process Overview • Non-contact cooling water • Polypropylene • Energy

  5. Motivations for Change • Optimize the use of water resources • Reduce wastewater • High energy costs

  6. Reasons for MnTAP Assistance • Analyze and understand water flow • Quantify and reduce water use • Understand the distribution of energy usage

  7. Approach • Understand cooling water effects throughout the process • Develop relationship between water flow and temperature

  8. Project Considerations • Criteria: • Prevent overheating the hopper • Account for temperature fluctuations • Ensure the flow of cooling water during operation • Avoid hot surfaces • Water and temperature data collection • Interactions with the team

  9. Flow Rates on Line 1 and 5 • Non-contact cooling water • Temperature change

  10. Flow Rates on Lines 1 and 5 • Opportunity • High water flow • Solution • Adjust flow rate (metering valve, flow meter)

  11. Surface Temperatures • Exposed hot services • Safety hazard

  12. Surface Temperatures • Opportunity • Surface temperatures on Lines 2 and 4 are above 120ºF • Solution • Adjust flow rate (metering valve, flow meter)

  13. Water Flow During Shutdown • Continuous water flow • Extruder shutdown

  14. Water Flow During Shutdown • Opportunity • Unable to automatically shut off water supply when a line is turned off • Solution • Normally-open solenoid valve with interlock system

  15. Line 6 Flow Rates • In the process of measuring flow rates • Low temperatures • Opportunity for significant water flow reduction

  16. Energy • Components: • 5 large extruders with heaters • 5 small extruders with heaters • 4 air compressors

  17. Energy Demand Charge • Opportunity • Energy spikes cause a substantial energy demand charge • Possible Ideas • Adjust start-up schedule • Increase efficiency of electrical equipment

  18. Successful Process Changes

  19. Personal Benefits • Experience working in an industrial environment • Professional/technical development • Better understanding of project planning and management • Data collection and analysis • Deeper understanding of safety/health policies • Working alone and on a team

  20. Questions? Thank you to everyone at MnTAP and GE for making this project possible
