A standard EPA-accepted or approved chemical oxygen demand (COD) test is required for EPA reporting, but a more rapid and mercury-free method is available for testing influent streams when reporting is not required.
Nitrate-rich effluent can be recirculated to the front of the plant, mixed with the influent water that is high in BO[D.sub.5], and then treated in an anoxic reactor (the first treatment unit).
The influent pumps cycle on and off frequently and create hydraulic surges throughout the plant.
The development of compact and efficient unit operations such as influent clarifiers, demineralizers, membrane separation equipment, and BOD reduction facilities all provide "more for less" to the paper industry.
