Book Description
Data was obtained for a direct comparison between the freeze conditioning and dewatering technique and the conditioning and dewatering methods presently employed at Milwaukee, Wisconsin. The laboratory investigation phase resulted in a freeze-conditioning system consisting of the following process elements: Flotation thickening prior to freezing, Freezing in thin sheets, Thawing of the frozen product, and Dewatering of the thawed sludge. The objective of the engineering design phase was the development of a freeze-conditioning system to handle three tons dry solids per day of activated sludge. Although the freeze conditioning concept, from a technical standpoint, has definite merit as a sludge conditioning process, the equipment capital costs, operating costs, and space requirements are appreciably greater for the freeze conditioning process than for the present chemical conditioning method.

Book Description
This 41st Edition presents case histories with operating data-and new research-on most topics of this major subject in today's world. This valuable Purdue Book will prove invaluable to all involved with waste treatment, providing information and data to help solve current problems. These proceedings of the May 1986 Purdue Conference include applications, research, methods and techniques, case histories, and operating data. The 91 papers include two special sections: 21 papers discuss toxic and hazardous wastes and 24 papers cover physical-biological systems. The book is further divided into papers on the following topics: (1) Pretreatment Programs and Systems; (2) Dairy Wastes; (3) Oilfield and Gas Pipeline Wastes; (4) Dye Wastes; (5) Coal, Coke and Power Plant Wastes; (6) Landfill Leachate; (7) Laws, Regulations, and Training; (8) Physical/Biological Systems; (9) Pulp and Paper Mill Wastes; (10) Plating Wastes; (11) Food Wastes; (12) Metal Wastes; and (13) Toxic and Hazardous Wastes.
