What are your biggest concerns about water use in breweries?
Many brewery operators encounter issues securing a steady supply of high-quality water and disposing of the environmentally hazardous wastewater generated from production.
Brewery wastewater, which can account for 70% of total water usage, comes mainly from processing and washing. Brewery wastewater is typically high in sugar and alcohol, suspended solids, with high variability in temperature and pH, high levels of biological oxygen demand, ammonia, and phosphorus.
There are often significant costs related to procurement of fresh water and subsequent disposal of brewery effluent. Many modern breweries are using membrane filtration to control incoming water quality to make better tasting products. Increasingly, they are using these advanced treatment systems to purify their wastewater to extract as much water as possible for reuse and reduce the amount of liquid waste requiring safe disposal.
Advanced membrane technologies like nanofiltration and reverse osmosis are improving brewers’ profitability by recycling up to three-quarters of the wastewater they generate back into high purity water. This lowers producers’ dependency on external water supplies and reduces waste volume to meet ever more stringent environmental regulations and achieve their sustainability goals.
