ITT (now Xylem) Water & Wastewater Leopold Business Unit has provided dissolved air flotation (DAF) systems to the municipal potable water treatment market since early 1990s. This chapter discusses DAF process and high-rate Clari-DAF® system design criteria. It also presents data from pilot studies case of full-scale plants in operation showing expected performance through system.

A study was carried out to determine the effect of water quality on flotation performance. The experimental test work comprised of batch flotation tests using Denver lab cell for a period of 10 minutes. Nine different test runs were carried out in triplicates to ensure reproducibility using different water types from different thickener overflows, return and sewage effluent water (process water...

investigations were carried out on coal tailings by conventional cell and column flotation techniques. tests were conducted to assess processing coal tailings of alborz markazi coal washing plant in iran by column flotation. the effects of reagent type/dosage were investigated with conventional flotation and their results were used in the performance of column flotation. also the effects of the...
