Industry: Data Center
Application: Cooling Water
Result: Savings of over 3MM Gallons and $10K every year
A data center in northern California expressed a desire to cut water use and increase control of the overall cooling system.
Sustainable Water Solutions LLC sampled and tested all appropriate waters and uncovered an opportunity for this client to save over 3 MM GPY while keeping heat exchange surfaces associated with a Trane cooling system clean. The Nereus System was deployed with immediate and outstanding results.
Flow meters were added to make up, bleed and recirculation lines thus allowing the measurement of water use and savings.
Temperature is measured in tower water supplied to and returning from the condenser, refridgerant entering and exiting the condenser, and ambient dry bulb. In addition relative humidity data is gathered.
Conductivity, ORP, and pH are measured on line.
Highly specialized chemical feed pumps are used that proactivly measure amount of chemical added to the system using discharge pressure sensing technology.
Alkalinity and Langlier Saturation Index is controlled using Condensafe II a 100% safe synthetic alternative to sulfuric acid. Scaling is and biology are controlled using water treatment formlations specifically designed to be effective in the Nereus system. The small amount of chemical that is needed,is loaded into double walled tanks where inventory is measured using ultarsolic level detection technology.
Calculations done by the system
Wet Bulb temperature
Chemical dose in ppm
Days inventory on hand
Heat Flux across Heat exchanger
Controls and communications
All aspects of the system are controlled. All data is recorded every 5 seconds. Out of spec readings trigger yellow and red state alarms which are sent directly to to those who need to know. Data and calculations are are available for review by users 24/7 via cell phone, I pad, or PC using Nereus wireless capability.
Products: Safety CR and Safety Clean AL
Application: Cleaning and Sanitation
Result: Increased safety for personnel, reduced labor and water costs
“The best benefit is that the products clean as well as the chemicals we were using before, but they are safer to use.”
Jim Lieb, Brewer, Rocky River Brewery
Rocky River Brewery is an award winning brewery and restaurant in Cleveland, Ohio, established in 1998. Their brewing operation utilizes a seven barrel system consisting of five fermenters and seven serving tanks. The brewpub places a high premium on safe operation for its valued workers and on maintaining an extremely clean and sanitized production environment.
To keep their brew house equipment free of contamination, Rocky River found they were forced to choose between significant labor costs of cleaning out (beer stone waste) by chipping and scrubbing, or using highly dangerous chemistry which require worker training, personal protective gear, and specific handling procedures/recordkeeping. Both options are costly and the later jeopardizes worker safety.
A year ago Rocky River turned to the Sustainable Water Solutions LLC’s (SWS) line of SAFE chemistry. Specifically, the brewery deployed the Sustainable Water Solutions Safety CR after each production batch to clean and sanitize their fermenters and lines. Approximately twice a year the fermenting tanks are cleaned with Sustainable Water Solutions LLC’s Safety AL, an acid extremely effective at removing beerstone.
According to the plant manager, the SWS products do an excellent job cleaning and sanitizing the fermenters, serving tanks and lines. Additionally, worker safety is improved while providing the same level of cleaning and sanitizing as the highly caustic products used previously. As a result, the brewery has had zero worker safety incidents related to cleaning and cleaning chemistry.
