Since 2005, five PSS 3.2-1040 separators from FAN have been running in the waste management center Friesland/Wittmund. The separators are used in a biogas plant after fermentation of the organic fraction of the residual waste and are fed with the digestate that is removed from the fermenters. After separation with the PSS, the liquid medium is filtered again in a decanter and separated from the residual solids. The liquid fraction left over here is reintroduced into the process. The solids are landfilled after separation.

FAN separators also cut a fine figure in sewage treatment plants. Like this PSS 1.2-520 with 4 kW motor and 1mm screen in Denmark. The big advantage over other machines such as decanters is the low power consumption of around 5 KW per hour and the low maintenance effort. The separated solid is used to generate electricity and heat in a biogas plant, the liquid phase goes on to a secondary sewage treatment plant.
