The system shall be designed and installed in a way that allows for potential future integration of septage and thickened sludge heating if desired, without requiring major rework. A. Tank Configuration Provide 2 design options for tank configuration Option 1 – Keep FOG service at Tank #1 Option 2 - Repurpose Septage Receiving Tank #3 for FOG service and relocate glycol storage to Tank #2. Note a new bar screen will need to be added for FOG delivery. Ensure all tanks are finished with corner edge grouting and radius as planned. B. Heating System Install stainless steel (or equivalent corrosion-resistant) multi-pipe heating loops, estimated 4–8" diameter (final sizing to be based on heat transfer performance requirements), mounted around the interior walls of Tank #3.
