The proceedings of this seminar outline the technical measurements, used by pollution control technologists, as they apply to the dairy industry. Technical terms used in the laws which control wastewater discharge are defined in industry terms. Waste quantities are expressed in standard parameters used in waste control regulation. Significance, sources, loadings, and limitations for each parameter and methods of analysis are discussed. Finally, a plant wastewater survey and evaluation of data collected are described. The appendix is a paper which explains devices and techniques used for measuring flows and sampling wastewater streams.
