Easy Service Ejector Panels
|
This panel is built around
Superior Chlorination Equipment equipment for the
Town of New Castle, Colorado Water Treatment Plant, with redundancy for the
Ejector, the Remote Metering Panel and the Flow-Proportioning Valve.
 |
 The additional Remote Metering Panel in the center would be used to manually
boost chlorination if the use exceeded the 25 PPD Auto-Valves. |

Panel by Mike Bean
A Water Treatment Plant Operator at the Town of
Wellington, Colorado, Mike built this panel and included a Rotameter to
measure the flow as well as having the pressure gauges for Supply and Back
Pressures. |
|
This panel is built around
Severn-Trent Services / Capital Controls equipment with Secondary
Check valves in the gas supply lines.
This protects the Regulators (not
shown) from water damage should the Ejector Check Valve become fouled. |
Note: If the ball valves are open to the gauges
fulltime, they would need to be shut off and drained periodically, like
once a week, to flex the Bourdon tube inside and "function-check" the
gauge.
If a 30 second
shutdown of the SYSTEM is possible, just shutting down the inlet side of
the EJECTOR should accomplish this. This allows SYSTEM service checks or
problems to be more accurately accomplished. |
Easy Service Rotameter Panel
|
This Rotameter Panel was built with
Redundancy and ease of maintenance for the Boulder Water Treatment Plant
for Danny Freeman, Operations Supervisor.
|
Note: On an Ejector line, NEVER shut down the downstream valve before
the upstream valve! This applies FULL SYSTEM PRESSURE to the Ejector Check Valve
and if it's fouled, would allow water to flow back to the Auto-Valves and
Ejectors which are rated for DRY Chlorine gas, not Chlorine Solution. If water
does reach the equipment, Auto-Valve or Regulator, FULL DISASSEMBLY & CLEANING
is NECESSARY TO PREVENT DAMAGE. Permanent damage can occur.
Construction of these and other devices are
covered in my Chlorine Maintenance Training Classes.
All of our Training Classes are approved by the
Colorado's Operators Certification Program for TU's. |
