Fixed film Fixed Film Trickle Filtration is a process used to reduce Biological Oxygen Demand (BOD) and ammonia nitrogen levels. Trickling filters are composed of a bed of porous material (rocks, slag, plastic media, or any other medium with a high surface area and high permeability). Wastewater is distributed over the surface of the media, where it flows downward as a thin film over the media surface for aerobic treatment. The wastewater is then collected at the bottom through an under-drain system. The effluent is then settled by gravity to remove biological solids prior to being discharged. View None

Flake Flake: Flake ice machines produce ice continuously, usually in a barrel-shaped evaporator. An auger inside the evaporator scrapes ice off the sides into a storage bin. View None
Flash steam Flash steam plants are the most common type of geothermal power generation plants in operation today. Fluid at temperatures greater than 360¡F (182¡C) is pumped under high pressure into a tank at the surface held at a much lower pressure, causing some of the fluid to rapidly vaporize, or "flash." The vapor then drives a turbine, which drives a generator. If any liquid remains in the tank, it can be flashed again in a second tank to extract even more energy. View None

Flicker The impression of unsteadiness of visual perception induced by a light stimulus whose luminance or spectral distribution fluctuates with time. (CIE 17.443 e-ILV) View None
Flicker index A measure of the cyclic variation in output of a light source taking into account the waveform of the light output. It is the ratio of the area under the light output curve that is above the average light output level to the total area under the light output curve for a single cycle. (ANSI/IES RP-16-10) View None
