At Pantarein Water, we invest in long-term partnerships and water treatment solutions that grow with our customers. Our collaboration with Huyghe Brewery in Belgium – best known for Delirium Tremens – is a perfect example.
Our journey started in 2012 with the development of a master plan: a step-by-step roadmap to increase the capacity, sustainability and circularity of the wastewater treatment over time. First step? We equipped the existing treatment plant with a membrane bioreactor (MBR), doubling its capacity and ensuring constant compliance with surface water discharge standards. In parallel, we worked with the brewery to optimise water use and limit losses in the production process.
In 2016, a new milestone followed with the commissioning of a reverse osmosis (RO) unit. This installation further purifies the treated wastewater to drinking water quality, which is then reused for cleaning operations, alongside tap and groundwater.
The brewery’s rapid growth led to a major expansion in 2019. An anaerobic pretreatment system now converts up to 80% of the organic load into biogas. After the anaerobic unit, the waste water flows to a second MBR and then to a second RO unit. This step-by-step approach enables Brewery Huyghe to reuse up to 70% of its treated water.
Back in 2008, the brewery used 8.6 litres of water per litre of beer. Today, it’s just 3 litres.
Since 2012, Pantarein Water has been monitoring the installation via remote control and regular on-site visits. A sustainable partnership in action!
