Reduce stillage disposal costs and complexity

Automated technology with remote access and mobile alerts

Reduces wastewater volumes and conserves freshwater

Opportunities to create higher value co-products

Solutions

Spiral Brush Filter

  • TSS and BOD removal from facility wastewater prior to sewer discharge to reduce surcharges
  • Screening wastewater before biological treatment in activated sludge, MBR or lagoons
  • Screening whole stillage to create high-quality thin stillage (50, 100, 200, and 500 micron screens available)

Stainless Steel Ultrafiltration

  • Filter thin stillage to create “ultrathin stillage” for reuse in cook process and “thick stillage” for animal feed
  • Ultrathin stillage can also be purified in TSRO to create clean water and a second concentrated product
  • Enables significant stillage reuse and reduced offsite hauling
  • Reduce load on existing evaporators by removing suspended solids from thin stillage, enabling reuse directly, and concentrating solids

Two-Step Reverse Osmosis

  • Generate clean water for facility reuse, such as boiler feed water or cook water
  • Concentrate ultrathin stillage into a syrup without an evaporator for 1/5th to 1/10th the cost of evaporation
  • Reduce freshwater consumption dramatically through beneficial reuse

Client Testimonial

The UF and Two-Step Reverse Osmosis system has shown to provide the exact solution that we sought in order to manage the whole stillage created at our distillery. The system allows us to run real time with our operation and to use our existing infrastructure of storage tanks and semi-tankers to completely manage what is generated per day without having to handle to a dried feed material at a much higher cost. It offers a smaller footprint and requires less energy to operate than a traditional system with centrifuges and evaporators.

We are able to provide a highly valuable concentrated animal feed at a greatly reduced daily volume instead of a watered down whole stillage, generate a clean ultra-thin stillage for use back in the process, and also a clean water stream that can be reused back in our process, for boiler feed water, or discharged to waterways.

The system provides an advanced automated and cost effective solution to an age old problem that has become more challenging with the growth in the industry.

Over our 13 years in the industry we have not come across a more effective system to remediate a distillery’s byproduct like this system can as either a complete stand-alone system or as a component to add efficiency to the traditional centrifuge and evaporation systems on the market.
