Fiber loss reduced and chemical use minimized with disc filter In 2011, a pulp and paper manufacturer located in the Northeastern U.S. required a modification to their existing process that would improve production efficiencies while also meeting stricter environmental standards. Specifically, the company sought a solution to reduce valuable fiber loss, minimize chemical use and decrease produced solids in the effluent discharge.

ADI® SBR technology helps Shanghai Xinlun Paper comply with stringent effluent limits 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).
