Filtration Processes | IWA Publishing
Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth

Dissolved Air Flotation (DAF) - Ideal DAF™ - World Water Works
Dissolved Air Flotation (DAF) systems remove suspended solids, fats, oils, greases and non-soluble organics by a process of dissolving air into water under pressure. The process begins with the water to be treated entering the DAF through an influent header box that reduces velocity and distributes the water across the length of the vessel.

Separation processes - processdesign - Northwestern University
Flash Distillation is one of the simpler separation processes to be employed in a chemical plant. The main premise of flash distillation is that a portion of a liquid feed stream vaporizes in a flash chamber or a vapor feed condenses. Vapor-liquid equilibrium will cause the vapor phase and the liquid phase to have different compositions.

Flash smelting - Wikipedia
Flash smelting ( Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur -containing ores [1] including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. [2] [3] It has also been adapted for nickel and lead production. [2]
