Brewing beer is water-intensive and most of it ends up as wastewater. The waste enzymes that result from beer brewing can cause considerable disruption to the sewer system. As a result, many municipalities have strict limits before releasing wastewater to the municipality.
Some forward-thinking breweries have chosen anaerobic digestion to combat these waste disposal issues. However, for optimal anaerobic digestion, and to protect sensitive equipment in the process, it is critical to pretreat the wastewater to remove coarse solids, like hops and spent grains. IPEC internally fed rotary drum screens from JWC Environmental are a cost-effective and reliable pretreatment solution to remove suspended solids from wastewater streams prior to reaching the anaerobic digester.
IPEC rotary drum screens use a wedge wire screen designed for the specific waste to optimize cleaning and minimize wash water use. An engineered headbox dissipates energy flow to optimize liquid removal and maximize throughput. The higher throughput allows a smaller IPEC screen to do the same job as many larger competitive screens. IPEC rotary drum screens are known for their rugged construction for reliable performance and minimum maintenance in tough industrial wastewater applications. JWC will work with customers to specify the right rotary drum screen based on the debris composition, flow rate, and end use for the screenings. WT
