ADI Systems is proud to have been selected by Oland Brewery in Halifax, Nova Scotia, Canada, to design and build a biological treatment system (BTS) to pretreat brewery wastewater. Oland Brewery, Nova Scotia's largest brewer, has been in the community for more than 130 years. It produces many popular beer varieties such as Budweiser, Bud Lite, and Alexander Keith’s.
After a competitive bid process, ADI Systems’ solution including the external circulation sludge bed (ESCB) technology was chosen for the project. The high-rate ECSB offers highly efficient anaerobic treatment in a reactor with a compact footprint. Since the brewery is located in close proximity to neighboring buildings, space limitations were very influential in the brewery’s BTS technology selection.
Aerobic polishing, solids removal, and dewatering will occur following anaerobic treatment within the ECSB system. The BTS will treat an average of 620 m3/d (0.16 mgd) of wastewater with a COD load of 3,329 kg/d (7,340 lb/d). The anaerobic digestion process will also produce valuable biogas that will be utilized in the brewery’s boiler, further lowering Oland Brewery’s operational costs.
The BTS that ADI Systems will design/build aims to reduce chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS) and total phosphorus (TP) concentrations to below the publicly owned treatment works’ (POTW) discharge limits.
