2.9 Injector Water Supply
The injector requires a supply of reasonably clean water. Equip the water supply
with a strainer, as indicated in the typical installation drawing in this section. The
pressure and quantity of water required varies from one installation to another.
2.10 Drain
A floor drain is always desirable to facilitate injector service and for the injector
drain relief valve (if installed).
2.11 Injector Discharge
A rigid PVC pipe or Evoqua Water Technologies solution hose is required between
the one-inch fixed throat injector discharge and the point of application. The
size depends on the size of the throat and tailway used in the injector. Solu-
tion hose may be connected directly to the injector tailway. If rigid PVC pipe is
used, a piece of straight pipe at least eight inches long should be coupled to
the end of the injector tailway before any elbows, tees, or Saunders valves are
used. This is to prevent any flow disturbances that could affect the hydraulic
performance of tailway connections (see Dwg. 25.200.003.010).
2.12 Point of Application
2.12.1 Main Connection
If the solution is to be applied in a main, a suitable pipe tap is required in the
main to accommodate the solution tube or diffuser.
2.12.2 Open Well
If the solution is to be applied in a basin, flume, channel, etc., where there is
no pressure, the line from the injector must be supported so that the open
end is submerged to the bottom of the chamber, if possible, or a minimum of
six feet, and is located in a nonstagnant area.
2.13 Vacuum Regulator
A vacuum regulator, which is a gas pressure reducing valve and check, is con-
nected to the control module inlet. Refer to the separate instruction book
supplied with the unit for installation instructions for the unit.
