“With traditional [salt-based] systems, if flow is below peak rate, you can get hard-water bypass,” continued Callahan. “That’s when water finds the path of least resistance through the media, and comes in contact with minimal amounts of resin.”
According to Callahan, TAC media isn’t sacrificial; it doesn’t dissolve. Media lifecycle is not influenced by the amount of water being treated, or the hardness of the water. However, impurities in the water, such as chlorine, over time can degrade the template on the beads, which affects media longevity. The typical suggested media change-out is three years.
“Selecting the appropriate size system is simple. All you need to know is peak flow rate,” said Callahan.
The first phase of the Ft. Sill restoration project called for 12 OneFlow tanks, each capable of handling 75 GPM. Linked in parallel, the tanks treat up to 900 GPM. This system also affords the base the flexibility to isolate tanks if the barracks aren’t at full capacity, and to perform media change-outs one tank at a time.
Four and eight-inch Watts model 957 RPZ backflow preventers protect the domestic water system. Strainers installed upstream of the RPZs help keep debris from getting into the OneFlow system and backflow preventers.
“For the Army Corps of Engineers to review and ultimately select TAC technology over a traditional softener, it meant that we had to meet a very strict performance standard to protect their plumbing systems,” Callahan said.
“We have thousands of installations, some in areas where water is even harder than at Ft. Sill, so I was certain our technology was best suited for water use at Fort Sill,” he added. “They’ll reap the benefits of zero water discharge and no salt expense for years to come.”<< previous 1 2 3 4 5 6
