Mason Farm Wastewater Treatment Fermenter Mixing Equipment Installation

Goals: 10% The Project consists of furnishing all materials, labor, equipment, tools, etc. unless otherwise specified, for the complete and operable installation of: 1. Demolition of existing pipe and mixing headers and their associated structural supports inside the fermenter tank up to wall pipe connections. 2. Demolition of two submersible pumps and associated piping up to wall the fermenter wall pipes in the basement of the Old Digester Control Building. 3. Demolition of the existing, insulated, 24-inch diameter standpipe on the first floor, including the 6-inchpipe that penetrates the first floor to the basement, and the vent pipe that penetrates the roof and is routed to the center dome of the fermenter tank. 4. Removing and supporting a small section of the floor separating the basement and 1st Floor of the Old Digester Building to provide a pipe chase between the floors. 5. Excavation and demolition of underground fermenter gas condensate pipe, as well as its associated drip trap in the basement of the Old Digester Building. 6. Optional removal and reinstallation of a 6-foot by 6-foot section of the concrete cover for the fermenter tank to provide easier access to the interior of the fermenter. This would include the associated PVC liner repair. 7. Installation of new mixing nozzles and associated pipe and supports in the fermenter tank, as well as new withdrawal piping and supports in the fermenter tank. This includes spot repairs to the existing PVC liner as required. 8. Re-routing of above head gas piping and electrical conduit to make room for the new mixing pumps on the first floor of the Old Digester Building. 9. Installation of two vertically mounted centrifugal chopper pumps on the first floor of the Old Digester Control Building, as well as installing a new column support in the basement to support the new pumps. 10. Installation of new pipe, valves and supports in the basement and first floor of the Old Digester Control Building. 11. Installation of new gas condensate accumulator and associated drain and vent piping improvements. 12. Repair and coating of corroded sampling hatches in the fermenter cover. 13. Electrical improvements for power and controls of new equipment. 14. Installation of new level and flow instruments and integration of new controls with the plant-wide SCADA system. 15. Repair of Fermenter Tank wall.
