Revolutionary distillery technology

Distillers will be all too aware of the challenges involved in treating pot ale. It’s just as well we thrive on a challenge. We have identified a game-changing process which makes remediating pot ale from distillery effluent a much less laborious task.

EPONA technology provides an ingenious, economic and greener alternative to traditional methods. Not only can the system be customised to optimise valuable solid by-products with high protein intake, but it also allows for the environmentally safe discharge of water.

Over 2.7 billion litres of pot ale are produced annually.

What’s in it for you and the planet?

  • Less energy intensive treatment of pot ale
  • On-site treatment solution
  • Reduction in effluent handling costs
  • Easy modular design and implementation
  • Decarbonisation of the co-product handling process
  • Water is treated for reuse or safe environmental discharge

Sustainable by-product production

  • High Protein Solids
    Treated pot ale solids contain ~35% protein on a dry weight basis.

    The EPONA process allows for high protein solids to be generated from effluent. These can be repurposed to produce by-products such as animal feed. The large percentage of dry matter yields a higher energy and protein content than pot ale syrup.

  • Reusable Water
    52 billion litres of water are inputted into the distillery process in Scotland annually.

    The EPONA treatment process cleans and treats water, allowing it to be safely discharged to the environment, or reused in whisky production. Our team of field engineers have conducted multiple on-line trials which have proven the technology to be extremely reliant in ensuring that clients meet strict consent to discharge (CTD) regulations. A trial based at Glen Moray distillery showcased an 88% reduction in copper and a 30% reduction in COD post treatment.

Applicable SDGs

How does the pot ale treatment technology work?

  • EPONA removes volatile contaminants and dewaters effluent streams.
  • It captures difficult micro-solids in an energy efficient process.
  • A solid pot ale putty is produced which can be transformed into saleable by-products.
  • Water is also cleaned for safe environmental discharge and/or re-use.
