millwise | WATER TREATMENT Doubletree Paper Upgrades its Water Treatment System New technology lets this Arizona-based mill double water purification capacity while reducing wastewater and energy use A PAPER 360° STAFF REPORT In 2014, Arizona-based paper manufacturer Doubletree Paper Mills started up new state-of-the-art water treatment for their expanded manufacturing operation in Gila Bend. Doubletree purifies groundwater and recycles wastewater with reverse osmosis for use in its paper producing processes. The new integrated water treatment system, supplied by Massachusetts-based Desalitech, doubles its water production capacity to 400 gallons per minute while drastically reducing wastewater production and energy use. Doubletree previously treated groundwater pumped from a well to the plant with a conventional reverse osmosis system at a water recovery rate of 75 percent, producing 50 gallons of wastewater from every 200 gallons of raw water fed to the system. The environmentally conscious manufacturing company replaced their existing conventional reverse osmosis units with Desalitech ReFlex Reverse Osmosis systems featuring CCD technology. This new installation boosts water recovery on their high-purity process water stream to 90 percent, reducing wastewater production by almost a factor of three while reducing energy use by nearly 25 percent. "Product quality, environmental sustainability and safety are our top priorities when considering any changes to our facility's operations," says Samir Kanuga, Doubletree's VP of finance. "The culture at Doubletree encourages our employees to seek and identify opportunities to reduce operating expenses, especially if carbon and water footprint can be reduced in the process. This is a solid upgrade to the water treatment system and has enabled us to increase water production without any additional stress on the existing facility." For Desalitech, this installation brings the number of project wins to more than 30, solidifying the high efficiency water treatment company's place as a new, but serious contender in the water treatment industry. "Product quality, environmental sustainability and safety are our top proiorities when considering any changes to our facility's operations." The new Desalitech integrated water treatment system increases water production capacity by 100 percent, to 400 gallons per minute, while drastically reducing wastewater production and energy use. Although drought conditions have recently acted as a catalyst for change in many operations across the Western and Southwestern U.S., Doubletree has been implementing sustainable practices since their inception eight years ago. Their commitment to water and energy reduction stems from a balanced focus on the company's bottom-line, the environment and their surrounding local community. Doubletree Paper Mills is a family-owned paper products manufacturing company based in southern Arizona that manufacturers retail and away from home consumer products such as bath tissue, facial tissue, napkins and towels. About Desalitech Desalitech, headquartered in Newton, MA, provides high efficiency water treatment for industrial, agricultural and wastewater reuse and concentration applications. Its next-generation ReFlex(TM) Reverse Osmosis products feature patented CCD(TM) 22 Paper360º SEPTEMBER / OCTOBER 2015 technology - a highly efficient, reliable and flexible water treatment platform. The CCD process typically reduces waste by 50 to 75 percent and energy consumption by up to 35 percent, saving significant operating costs.
