Inadequate groundwater supplies prompted Cooper Farms in Ohio to begin harvesting and reusing rainwater in 2009 as a supplement to its potable water supply and to reduce its demand on the local groundwater system.
Since one of the key uses for the treated rainwater is to provide drinking water for livestock, Cooper Farms started exploring options to implement a multi-barrier treatment process with UV disinfection that could provide pure, safe water. Rainwater can acquire a multitude of contaminants and pathogens as it is collected, so treating it to potable water quality standards is essential for preventing disease outbreaks and death among livestock.
Upon the recommendation of Flag City Water Systems, a local UV Pure representative, Cooper Farms installed a purification system that includes chemical-free UV Pure disinfection for its ability to handle low UV transmittance (UVT) conditions, a typical characteristic of the rainwater, which is collected and stored in a retention pond at the site.
UV Pure disinfection enhances system performance and provides peace of mind
“We worked closely with UV Pure to design and install a water treatment system that meets Cooper Farms’ needs,” says Brad Longberry, CEO of Flag City Water Systems. “Even after pond water is filtered, UVT can still be quite low, so the ability to consistently deliver a high UV dose under these conditions was a very important consideration for us when selecting UV Pure’s Upstream systems with Crossfire Technology for this application.”
The system at Cooper Farms is designed to treat source water to a potable standard. Currently, a small amount of well water is pumped into a retention pond which is supplemented by rainwater. The blended stream first passes through a microfiltration system that uses a specialized five-micron filter to remove organics and then dosed with chlorine.
“Once chlorination is complete, the water requires additional purification which is provided by UV Pure’s Upstream systems,” Longberry says. “UV disinfection inactivates pathogens like Cryptosporidium, Giardia and Legionella that can be resistant to chlorine. Proper UV disinfection also provides a second layer of protection to enhance the system’s performance and reliability since the changes for a potential disease outbreak are always very real for Cooper Farms.”
The final disinfection in each system is performed by one to four Upstream NC 15-50 systems that are each sized to handle flows from 15 to 60 gpm (57 to 227 L/min) of water, with UVT as low as 50%.
Crossfire Technology targets pathogens from every angle
UV Pure’s Crossfire Technology incorporates elliptical reflectors that reuse light energy to deliver a high UV dose and target pathogens from 360 degrees.
Dual smart UV sensors in the Upstream systems continually monitor UV lamp output and water quality to ensure the highest level of treatment is consistently delivered to protect Cooper Farms on an ongoing basis. If either of these parameters does not meet the set specifications, the systems will sound an alarm, notify the operator and automatically shut down.
“Overall, our partnership with UV Pure has been excellent,” Longberry says. “As a UV Pure distributor for the last 20 years, Flag City has received great technical support and fantastic systems in a timely fashion.”
