OPTIMIZATION OF COMPLEX TECHNOLOGY FOR GREASE WASTES UTILIZATION

Environment. Technology. Resources. Proceedings of the International Scientific and Practical Conference, 2015
Lipids constitute one of the major types of organic matter found in municipal wastewater. Many manufacturing, food processing and industrial facilities dispose of liquid waste into sewer lines. Liquid waste often contains fats, oils and grease and other organic contaminants which, over time, lead to clogs in pipes.
