Dissolved Air Flotation in Industrial Wastewater Treatment

Dissolved air flotation (DAF) is a process for removing suspended particles from liquid by bringing particles to the surface of the liquid. The influent feed liquid can be raw water, wastewater or liquid sludge. The flotation system consists of four major components air supply, pressurizing pump, saturator (retention tank), and flotation chamber.

Nov 01, · The case of salt flotation is an example of a very clean system in which only the effect of electrolytes on surface properties of mineral particles, and on foaming, is to be studied. In all other cases in which collectors are also utilized, the effect of electrolyte concentration on properties of these agents has to be considered as well.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation

Introduction to Mineral Processing or Beneficiation

Jan 12, · In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.
