MVR-TVR WasteWater Evaporators
Recent applications of C. E. Rogers Company's years of expertise in evaporation have been applied to the processing of wastewater. Now the company with 115 years of design knowledge and expertise in evaporators can provide you an answer to your wastewater disposal problems. Each evaporator system is specifically designed to reduce volumetric sewer loading while producing environmentally friendly condensate (clean water).

In many cases, the concentration requirements required for wastewater lends itself ideally to Mechanical Vapor Recompression (MVR) based evaporation. The MVR wastewater evaporator system is based on C. E. Rogers' proven thermal/tubular designs and incorporates a customized multi-staged liquid distribution system.

C. E. Rogers' pilot-lab facility can test your wastewater samples for thermal evaporative characteristics, concentrate and condensate analysis.

C. E. Rogers' first and very successful installation of a MVR Wastewater Evaporation System was for a dairy processing plant. This plant produces 100,000 gallons per day of plant wastewater consisting mainly of wasted milk products and discharge from different cleaning systems. To process this wastewater stream a C. E. Rogers MVR Evaporator System was installed.

This plant saves approximately $500,000 a year in reduced wastewater discharge fees by using a C. E. Rogers Company MVR Wastewater Evaporator. This system reclaims over 33 million gallons of water per year for local ground water recharge and irrigation. Another plus for this system is that the concentrate produced has a significant protein content and is sold for animal feed.

Operating costs for this MVR Evaporation System average about a penny a gallon, including energy, labor, and materials.

Thermal Vapor Recompression (TVR) evaporation can also be used for wastewater applications. C. E. Rogers was contacted by a Michigan company that reclaims de-icing fluids used at the Detroit Metropolitan Airport; where approximately 800,000 gallons are used annually. The question asked C. E. Rogers was - can a C. E. Rogers evaporator system be used to concentrate propylene glycol from reclaimed airplane de-icing fluids?

The answer to the question was YES!!

The next question asked was how inexpensively can this be done and how quickly?

The answer was very reasonably and in a short period of time.

C. E. Rogers had in its possession a used three-effect TVR falling-film evaporator (1974) that had been removed from its original location in Kentucky. This system was purchased in early November 1997, reconditioned, modified and installed by mid February 1998. This equipment has been able to concentrate propylene glycol up to 80% concentration. A second MVR Evaporation System was subsequently ordered and installed at the Salt Lake City Airport.
