Flotation constitutes a separation process that originated from mineral processing. Nowadays, wider applications have been found and compared to flotation for water and wastewater treatment. Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed, being either ion, precipitate, or sorptive flotation.
The Komline-Sanderson Dissolved Air Flotation Clarifier is designed for the removal of suspended solids or water immiscible liquids from process or wastewater to produce an effluent of high clarity and free of objectionable particles or liquid. Dissolved air flotation is best applied to remove materials that normally settle slowly, persist by ...

The project included modifying the existing aerated lagoons to provide equalization and biological treatment, and adding a dissolved air flotation DAF unit to remove fats,
Aug 02, 2013 The treatment performance of the full-scale AquaDAF system has been similar to that of the pilot plant. The effluent turbidity is approximately 0.5-0.6 NTU, with influent turbidity varying from 1.11-7.17 NTU. The TOC concentrations of the raw water have been higher than those during the pilot testing period and range between 2.0 and 3.1 mgL.

A well designed DAF treatment system will take up a relatively small plant foot print, and also lead to lower capital and operating costs. A dissolved air flotation DAF system resolves suspended solids and clarity issues by reintroducing a slip stream of treated water from the systems effluent back to the systems influent.
Treatment and Recycling of the Process Water in Iron Ore In iron ore flotation process, a large amount of NaOH is taken to adjust the pH. The wastewater pH of iron ore is more than 9, so physicochemical treatment of iron wastewater from a certain degree is rather difficult 9 Wenli Jiang, Haifeng Xu 2 2017Overview of flotation as a wastewater treatment technique Mar 01, 2002 1.4.
