Food/Beverage Processing Wastewater Recovery and Recycling

Through a multi-phase study, Exergy D&E designed and built a comprehensive wastewater recovery and reuse system, integrating micro-filtration, ultrafiltration, reverse osmosis, ultraviolet light, and ozonation technologies. The final design enables the reuse of treated water for steeping operations, benefiting the client with ongoing stormwater compliance, wastewater reuse, and cost-effective analysis of advanced treatment technologies.



  • Ongoing compliance for stormwater program

  • Reuse of the wastewater generated from the manufacturing operation

  • Evaluation of various technologies to allow the reuse of the wastewater generated at the plant

  • Cost/Benefit analysis of the new recovery/ recycling technologies

Exergy D&E has partnered with GWM to successfully develop and implement a stormwater pollution prevention plan program. With a commitment to ongoing compliance, Exergy D&E has taken charge of monitoring, conducting visual inspections, and performing stormwater sampling for the facility.


Moreover, Exergy D&E has diligently prepared the annual report to the Regional Water Quality Control Board, ensuring seamless execution of the stormwater pollution prevention program.

In parallel, Exergy D&E has undertaken an extensive two-year collaboration with a major malt product manufacturer to explore the possibility of recovering and reusing wastewater generated during the facility's manufacturing process. By conducting comprehensive evaluations, Exergy D&E analyzed the nature of wastewater contamination from steeping processes, characterizing pollutants through various sampling programs.


Through a small-scale pilot unit, Exergy D&E assessed preliminary technologies, revealing the need for more advanced filtration solutions to address pollutant levels and suspended solids.

Building on the initial findings, Exergy D&E moved forward with the design and construction of a state-of-the-art wastewater recovery and reuse system. Incorporating micro-filtration, ultrafiltration, reverse osmosis, ultraviolet light, and ozonation, this integrated package underwent rigorous pilot testing at the facility for about three months. The thorough evaluation allowed Exergy D&E to conduct a comprehensive cost analysis and determine the most effective technologies to include in the full treatment train while eliminating less viable options.

Looking ahead, Exergy D&E is dedicated to developing the final design and providing a cost estimate for the proposed system. This innovative solution aims to significantly reduce contaminants to acceptable levels, enabling the reuse of water for steeping operations. As the project unfolds, Exergy D&E remains steadfast in its commitment to delivering sustainable solutions and propelling the client toward a more efficient and environmentally conscious future.
