Food & Beverage Company


  • Recovered about 75% of wastewater as clean water for sewer discharge without surchages
  • Enabled facility expansion
  • Created value added co-products from filtration concentrates

Case Study: Food & Beverage Wastewater

A Food & Beverage company produces 25,000 GPD of wastewater from their facility. They have been hauling wastewater to a nearby treatment facility but have been unable to expand their production for years due to limited capacity for wastewater treatment. With our advanced filtration solutions, we can create clean water for reuse or discharge and a concentrates that can be turned into value-added co-products.

Company Issue / Challenge

The company is currently paying high fees to dispose of wastewater and is unable to expand production without a new treatment system or avenue for disposal.

The cost for hauling wastewater away is high.

Managing the storage and hauling of wastewater is a constant challenge and requires coordination of various trucks throughout the day.

Management wants to expand production at the facility but cannot due to limited avenues for wastewater treatment. This is holding back significant company growth opportunities as well as new jobs.

What We Delivered


Site Assessment

Worked with the Food & Beverage Company to understand its unique challenges and brainstorm how best we could assist.

Pilot Testing

We collected samples of raw wastewater and used our UF and TSRO systems to create clean water that can be reused or discharged directly to waterbodies or put in the sewer with few if any surcharges.

Impact & Benefits

Our filtration systems are designed to recover clean water in high proportions from food and beverage wastewaters while making value-added co-products.


Clean Water Reclamation

The reclaimed water can be directly discharged into waterbodies or sewer discharged.

Solids Concentration

Concentrates can be sold as animal feeds or other specialty products.

Facility Expansion

By managing wastewater smarter, the facility can now expand its operations and production, helping improve financial returns and creating new jobs.

These data reveal that the raw wastewater had a total solids content of 5.16%, the majority of which were soluble or dissolved solids that passed through the UF membrane. These dissolved solids were then concentrated by the TSRO system, producing very clean water and a second concentrate product, as shown in the table below.

Despite the high solids content of the UF permeate, the TSRO removed 99% of the total solids. The removal of organic material, measured as Chemical Oxygen Demand, was excellent, with the TSRO permeate having 20 mg/L COD, down from about 41,000 mg/L COD in the feed. These data demonstrate that our TSRO system, which combines Forward Osmosis and Reverse Osmosis, can produce very clean effluent with low levels of organic matter. Also, the ammonia and phosphorus concentrations in the permeate were below detection limits.
