Shanghai Xinlun Paper was upgrading its pulping and paper-making process. As this was taking place, new regulations came into effect that required the mill to invest in secondary wastewater treatment so it could meet stringent effluent limits of 100 mg/l chemical oxygen demand (COD), 30 mg/l biochemical oxygen demand (BOD), and 200 mg/l total suspended solids (TSS).

Lamb-Weston required a wastewater treatment solution at its plant in Taber, Alberta, Canada. Its potato processing wastewaters are characterized by high concentrations of biodegradable chemical oxygen demand (COD); suspended solids (SS); and fat, oil, and grease (FOG). This type of wastewater has proven to be an ideal candidate for anaerobic digestion.

Golden Flake’s 50 acre (20 hectare) Birmingham, Alabama, USA, corporate headquarters is home to a 350,000 ft2 (32,516 m2) manufacturing facility that processes more than 20 million lb (9 million kg) of snack foods per year. The plant’s production mix can fluctuate, causing its wastewater to have varying strengths and consistencies, with flow rates ranging from 100,000-350,000 gpd (380-1,330 m3/d).
