Our engineers and fabricators have designed, fabricated, tested and deployed one-of-a-kind waste treatment technologies to aid our clients in managing radiological and chemical hazardous waste. Our innovative solutions support waste minimization, reduction, and treatment in compliance with Federal and state regulations.

Wiped Film Evaporator

Columbia Energy developed a nuclear-grade wiped film evaporator (WFE) system to consolidate and/or reduce liquid wastes prior to final treatment processing. We designed, built, and tested both a pilot and full scale evaporator. This technology would allow multiple unites to be deployed in a parallel configuration to adjust to varying concentrates and quantities. Read More on WFE.

Exhauster Ventilation Skids 

Columbia Energy designed, fabricated, tested, and delivered skid mounted ventilation units to Washington River Protection Solutions. The ventilation skids were needed to replace existing ventilation units on large underground steel-lined concrete storage tanks located on the Hanford Site in Richland, Washington. The tanks are used to store byproducts of plutonium production.  The ventilation system works to contain and control radioactive emissions during waste feed delivery and treatment.

SCIX (Small Column Ion Exchange)

Columbia Energy designed, fabricated, and provided a full-scale column mock-up demonstration test of a small column ion exchange (SCIX) for Savannah River Remediation (SRR). The test demonstrated the ability of the SCIX to remove cesium in the feed stream and the ability to sluice the ion-exchange media out of the column. Read More on SCIX.
