Environmentally Sound ED 2000 Cooling Water Management Programs What is ED 2000 ?

What is ED 2000 Program ? Comprehensive NON-CHEMICAL Cooling Water Treatment Program

ED 2000 Benefits Thermal Improved Heat Transfer & Energy Savings Maintain Head Pressure or Condenser Approach Temperature Chemical Elimination of Chemical Treatment Ordering, Handling, Storage, MSDS, Official Reporting Environmental Discharge Environmentally Acceptable Higher Cycles and Reduced Water Usage

Safety Liability Reduced Worker and Spill Liability, Reduced Pathogen Risk Mechanical Improved Understanding Removal of Suspended Solids and Microbiological Fouling Operational Improved Control, Monitoring, Flexibility & Ease of Administration Economic More Cost-Effective, Cost-Controlled Multi-Year Contract ED 2000 Benefits

Why ED 2000? Water treatment is subject to considerable variation and more effective control measures are necessary. Concentration changes in bulk water Make-up water quality changes Varied temperatures due to changes in plant production rates Inconsistent chemical feed rate (overfeed or loss of feed) Personnel changes It emphasizes ENVIRONMENTAL BENEFITS & ENERGY EFFICIENCY It addresses the CAUSES of scale, corrosion, fouling and microbiological control
