New Technology Solves Age-Old Problems at Fort Sill

(Continued)

The system changes the physical characteristics of the water with little or no change to the solution’s chemical composition. PWT is chiefly used to reduce the negative effects of water hardness (calcium carbonate) in plumbing systems, appliances and equipment, valves and other components.

The template influences the water solution at localized sites (on the media surface) such that hardness ions and their counter-ions (bicarbonate) combine to form inert nanometer-size “seed crystals.” Called nucleation, this occurs when dissolved molecules or ions dispersed throughout a solution start to gather to create clusters in the sub-micron size range.

The seeds provide an enormous area for preferential growth of remaining hardness ions still in solution. “Low energy heterogeneous transfer” then begins. The remaining dissolved ions reach their solubility shift, attach to the seed crystals and continue harmlessly downstream.

Out with the old…
“The Army Corps of Engineers in Lawton wasn’t impressed with the old traditional water softening system, or the service contract attached to it,” said Allen Jones at C.H. Guernsey, lead mechanical engineer on the project.

The mechanical room had been built around the existing system. Two tanks, one 10 feet tall, and the other five feet in height, were situated on either side of the mixing unit. The tanks were disassembled and removed.

“The Corps did their own research, looking for a better alternative financially, logistically and environmentally,” said Jones. “Mills was a bulldog when it came to explaining how TAC technology is the winner in all three categories, and also uses less than half the floor space of any of the alternatives.”

TAC: Unaffected by fluctuating water demand
Another huge advantage the TAC system has over a traditional water softener is the ability to operate effectively at trickle flow rates,” said Steve Callahan, national sales manager of water treatment products at Watts Water Technologies. “TAC media is always used in an up-flow design, so it’s not subject to low flow channeling or high flow pressure drops.”
