Protege firm to Washington River Protection Solutions Tank Operations ContractorTransportable Evaporator
| Columbia Energy offers a nuclear grade thin film evaporator (TFE) system to reduce liquid wastes prior to final treatment processing. By reducing water content in the liquid wastes, the storage capacity, the size of processing equipment and energy requirements are all reduced, thereby reducing capital costs and operating expenses overall.
Our systems are available in both transportable and permanent configurations. Multiple units can be deployed in either series or parallel configurations to adjust to varying concentrate and condensate quality requirements or varying processing quantities and rates. Additionally, the TFE system can operate in a continuous concentration loop or be set up as a single-pass evaporation operation.

 Permanent thin film evaporator system with multiple units The material fed to the TFE is held as a thin film against the heated wall by means of the centrifugal force exerted by the internal rotor blade, which constantly renews the film as concentrated material is displaced towards the bottom. The thinness of the material exposed to the heated wall allows for rapid heat transfer reducing holdup and residence time. Low material holdup within the unit reduces the quantity of shielding necessary to meet dose exposure constraints; for dilute or low-dose waste streams, self-shielding from the unit itself may be sufficient. The TFE also operates under a vacuum, which reduces the boiling point of water to approximately 120° - 140°F and enables up to 99% evaporation in a single pass through the unit. Evaporation rates will vary depending upon operational mode, input stream characteristics, desired concentration and TFE size. Systems are available from 0.1 gpm condensate to 10 gpm condensate. We maintain a 5,000 square foot testing facility where our engineers perform rapid process optimization studies on client waste streams in order to design and fabricate TFE systems to meeting specific operational criteria. |
