Fitec's self cleaning digester systems include a floor grit cleaner and a sediment separator.
FITEC sediment separator discharges the sand fraction that sinks to the ground during the operation of the plant.
FITEC floor grit cleaner regularly discharges organic waste contaminants that deposit at the digester bottom. This allows long-term operation.
Fitec’s self cleaning digester systems include a floor grit cleaner and a sediment separator.
After treatment, many organic wastes still contain compounds, which would deposit at the digester bottom (e. g. stones, sand, bone splinters, glass fragments, eggshells, …). For long-term operation, these sinking contaminants have to be discharged out of the digester regularly. Along with a grit pump and a sediment separator, the FITEC floor grit cleaner meets this requirement reliably.
With the patented geometry of the cleaner arms sinking contaminants can be removed by a discharge outlet in the digester bottom. From there the grit pump pumps the sinking contaminants to the sediment separator.
Inside the FITEC sediment separator the sand fraction sinks to the ground. The sediment-free supernatant is discharged through a weir back into the digester. A discharge screw discharge screw conveys the sand to a discharge outlet.
