2.01 GENERAL

A. All products furnished or constructed as part of this specification shall be in full compliance with all local, state, and federal laws, regulations, codes, and requirements.

B. The BFP shall employ three distinct dewatering zones: an independent gravity drainage zone at operator level, wedge pressure zone, and a vertical shear- pressure zone. At the end of the gravity drainage zone, the thickened sludge shall be cleanly discharged onto the belt at the wedge pressure zone. At the end of the shear-pressure zone, the dewatered cake shall be cleanly discharged from the BFP with doctor blades into a sludge diverter gate, provided by a separate vendor. All belts shall be completely washed as they return to the head end of the unit, showing no visible cake solids adhering to the belt.

C. The BFP shall achieve dewatering by the following sequence:

1. The independent zone of gravity drainage takes place through a filter belt located horizontally along the BFP (gravity zone). 2. The sludge is entrained between two continuous open meshed belts (wedge zone). 3. The cake which is sandwiched between the belts alternately has compression and shear applied to it as it passes over perforated and solid drums and rollers (vertical pressure zone); a belt tensioning system shall act on these rollers to provide ever increasing pressure as the sludge advances toward the discharge end.

D. The BFP shall be complete and shall include frames, distribution troughs, drainage and dewatering belts, belt drives, belt tensioning systems, belt alignment systems, doctor blades, belt washing systems, belt filter press feed pump, polymer makeup unit, control and instrumentation devices, drainage components, drum-roller assemblies and bearings, motors, terminal junction boxes, hydraulic control system, polymer mixing valve.

E. All parts of the mechanisms shall be designed and amply proportioned for all stresses which may occur during fabrication, erection, and operation.

F. BFP construction shall allow easy access to internal components. All operating adjustments shall be possible without interrupting operation of the BFP.

G. When stainless steel is specified as a material of construction, L grade stainless steel shall be used in any application that requires welding.

H. The BFP shall be designed with motor orientation, drain orientation, and BFP access as shown on the Drawings.
