Recent Paper Industry Waste Treatment Systems

The paper industry is the third largest discharger of industrial waste in the U.S. A great deal of experience has been gained in the design and operation of such treatment facilities. This information is contained in the records of the National Council of the Paper Industry for Air and Stream Improvement. The experience contained in these records is translated into design parameters. The application of these design parameters is illustrated with the case histories of two highly successful treatment plants. The first case history deals with an aerated stabilization basin system. The design of this plant shows excellent foresight in providing for the flexibility necessary in treating paper mill wastes and also reserve capacity necessary to protect the receiving stream under any conditions. The second case history is of an activated sludge system. This system illustrates an application where a high degree of treatment is needed at all times.
