Always apply good hydraulic fundamentals when considering the water treatment system design to avoid costly pitfalls. Typically, a design professional would look at the size of the effluent fitting of the tower or the diameter of the pipe and base the design on the length of run and height. This can be a fatal flow error if the tower is elevated on a structural stand and the height is tall enough to create hydraulic turbulence in the water flow.

When placed in a straight-up elevated location, a tower drain can experience a lack of flow, which causes tower flooding. This occurs when the water begins to vortex from the bottom of the tower because of the straight laminar pipe configuration. Vortex breakers must be incorporated in the tower design, such as a DI- VB100 series or other devices, to avoid this.

In addition, it is often required to add vacuum relief valves to let air enter the pipe, thus allowing the pipe to equilibrate the flow balance. You won't find these solutions in the standard engineering handbook. For more information or to learn more, contact the professionals at DeLoach Industries Inc. at (941) 371-4995.
