Modular Setup
1 – INPUT
The sludge is funneled into the system either by (1) dumping it into the connected storage tank or (2) automatically pulling it in with the integrated screw press.
2 – PRE-DRYER
The sludge is snaked through the machine via the conveyor system. Heat is used to dry the sludge to 40-50% dry solid content. (The hot air is generated by the pellet-powered heating unit.)
3 – EXTRUDER
The sludge is formed into pellets. (1 pound of pellets has the same heating capacity as 8 cubic feet of natural gas.)
4 – DRYER
The sludge is dried again, this time in pellet form, to 85-95% dry solid content. (Again, the hot air is generated by the pellet-powered heating unit.)
5 – OUTPUT
60-80% of the ISO 21640:2021 SRF pellets are automatically conveyed to the heating unit, where they are used to generate hot air. The heating unit's byproduct is phosphorus-rich ash, which can be commercialized (e.g., for fertilizer manufacturing). The remaining 20-40% of the pellets are collected and can also be commercialized (or used).
