Excerpts: Dairy waste water is a nuisance in every dairy plant. Management must get rid of this waste water either directly or after its treatment. Research on treatment of dairy waste has been underway at the Eastern Regional Research Laboratory since 1948 following the suggestion of the Subcommittee on Dairy Waste of the Dairy Industry Committee. Results have been published as phases of the study have been completed. These laboratory investigations were supplemented by a 3-year pilot-plant study at the Pennsylvania State University. Results, ideas, and concepts obtained in the laboratory have been verified in the pilot plant and adapted to industrial practice. The object of this report is to present in a concise, simple and complete manner information on the treatment of dairy waste as derived from the above studies. For more specific detail, reference is made to the appended list of publications, which have been selected from a total of about 40 that have been published since this work was undertaken.
