Cure Your Water Problems. Reduce Water Use and Decrease Energy Costs.

New, State-of-the-Art Hospital Saved Money, Water and Energy

Challenge:

As part of a cost-saving initiative, the hospital sought to reduce water and energy consumption, which would require a significant capital investment.

Opportunity:

Earthwise Environmental investigated the Nicor Gas™ energySMART rebate program. The natural gas rebate program — $1.00 incentive for each therm saved —would reduce the project payback period, allowing the hospital to undertake long-term conservation efforts. Without the incentive, the hospital would have been unable to undertake the capital improvements required.

Solution:

Earthwise Environmental installed a reverse osmosis system on the boiler feedwater. By removing supply impurities, the water could be cycled (concentrated) by a factor of 10. This cycling reduced boiler blowdown, water consumption and energy consumption.

Top Teaching Hospital in Chicago Increased Humidity and Saved Water and Energy

Challenge:

The existing steam humidification system was incapable of supplying the required amount of humidity to the hospital in general and to the operating rooms in particular.

Opportunity:

The system, as designed, was based on generating steam in one boiler, and using that steam in a Clean System Generator to produce steam to humidify. The system was energy intensive, inefficient and incapable of providing required levels of humidification. A steam plant/humidification retrofit was required.

Solution:

Earthwise Environmental proposed eliminating the Clean Steam Generators and designed a water chemistry program that exceeded the quality and purity requirements of the hospital. A new steam boiler with reverse osmosis treatment of feedwater was installed. Energy waste from inefficient steam generators was eliminated and sufficient steam could now be generated to meet humidification needs.
