Pretreatment Limits for Fats, Oils and Grease
43rd Annual Purdue Industrial Waste Conference, May 1988.
Summary: A discrepancy exists between the information available in the literature regarding oil and grease and the information used to establish limits for this materials. The goal of this chapter is to present information and recommendations that will be useful in the establishment of pretreatment limits for the discharge of oil and grease material to publicly owner treatment works (POTW's). The recommendations are intended to facilitate the development of regulations that will result in efficient use of POTW treatment capacity while minimizing the cost of pretreatment for industry. The chapter is organized as follows:
- Oil and Grease in Domestic Wastewater
- Physical and Chemical Characteristics of Oil and Grease
- Operational Problems
- Pretreatment Regulations
- Regulatory Approaches
- Pretreatment Technology
- Summary Recommendations for Oil and Grease Limits
