Keeping power plant storage pond levels within required limits means staying in business.

So when this station's pond inventory began to climb, PPL contacted us for an engineering evaluation of potential treatment processes. The goal? Reduce pond inventory by 250 million gallons per year for the next five years.

With a focus on maintaining the plant's balanced water system, we studied options for recycling water onsite and recommended vibratory shear enhanced processing (VSEP). At the Colstrip station, a pilot study using VSEP membrane technology revealed an average water quality conductivity of 1,400 S/cm at 75 percent recovery, enabling the permeate water to be used in select portions of the power plant process. With this knowledge, PPL enlisted us to move forward with design-build services for VSEP technology integration at the station.

With the full-scale treatment plant complete, and other water handling recommendations implemented, PPL has effectively reduced the storage pond inventory.
