Abstract Costs for flotation thickening are presented here in two ways. First, capital cost and operating and maintenance cost are shown as functions of the design capacity of the sewage treatment plant. Second, construction cost, man-hour requirements, and materials and supply costs are presented as functions of appropriate process sizing parameters. This makes the costs, for this process, compatible with the costs of other unit processes given in other reports.
Highlights Notes Estimates of capital and operating costs and operation and maitenance labor man hours.
