Horizontal Flow - Model 16A T/S
Standard
Flowrate: 3.5 MGD (13,200m3/day)

Specifications - Model 16A T/S

1.0 General Specifications

There shall be furnished one (1) one only Grind Hog™ Model 16A T/S Comminutor as manufactured by G.E.T. Industries, Inc. Rotation shall be in a clockwise direction.

1.1 Design Criteria

The comminutor shall be designed to handle the flows indicated below, within the head loss noted.
  • a) hydraulic capacity 3.5 MGD (13,200m3/day)
  • b) satisfactory operation shall occur under conditions of zero flow
  • c) head loss at peak flow shall not exceed 20 inches (500)
  • d) design shall be such that the flow enters the size reduction and screening device horizontally and exists vertically downward to facilitate the flushing of solids

1.2 Cover Plate

Shall be:
  • a) fitted with 4 position lock down arrangement, and 2 alignment holes for repositioning following service
  • b) located on, and positioned by wall mounted supports allowing for ease of removal for inspection and maintenance.
