Technical Bulletin No. 0178: Settleable Solids Removal Practices in the Pulp and Paper Industry

The attached Technical Bulletin was first issued in 1964, and summarized a survey of settleable solids removal practices at 55 mills located in the Southern Region.  The survey's objective was to assemble the data needed to provide a sound basis for design and operation of the then growing number of mechanical clarification installations in the Southern industry. It was judged at that time that the study has met those objectives. While a large number of mechanical clarifiers have been installed since then, it was felt that this information assembly is still of interest to the membership, and is therefore being kept in print.
