... In the first step, ammonium is oxidized to nitrite by autotrophic ammonium bacteria. In the second step, nitrite is oxidized to nitrate by autotrophic nitrite oxidizers. In denitrification process, nitrate is reduced to nitrogen gas (N2) by heterotrophic denitrifiers (Li and Irvin, 2007). Phosphorus ...

Belt filter
The belt filter (sometimes called a belt press filter, or belt filter press) is an industrial machine, used for solid/liquid separation processes, particularly the dewatering of sludges in the chemical industry, mining and water treatment. Belt filter presses are also used in the production of apple juice, cider and winemaking. The process of filtration is primarily obtained by passing a pair of filtering cloths and belts through a system of rollers. The system takes a sludge or slurry as a feed, and separates it into a filtrate and a solid cake.
