RESOURCE CONSERVATION AND REUSE

Municipal services

Resource conservation, reintroduction of reusable substances into economic circulation and inexpensive disposal that is easy on the environment are all key topics for municipal services providers. A chain of complex processes consisting of mechanical processing, fragmentation, multiple levels of sieving and filtering as well as strict regulations are consistent themes in the industry. In this setting as well, FAN separators do valuable work and are popular additions to sewage treatment plants and waste management centres.

Separator PSS 1.2-520 in Kläranlage Dänemark

Waste separation for pros

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.

Ideal for sewage plants

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.
