ECONET VMT entrusted SPIRAC to install a round Sliding Frame Silo for Sludge storage. The required volume for the new sludge Sliding Frame silo is 120m3 and the outloading capacity is 80m3/h. The diameter of the silo is 3.82m and its total height is approx. 15m. The sludge dry substance content is between 18% and 24%.  The silo is insulated and includes heat tracing to keep the sludge within the silo from freezing during winter.
