OPERATION AND MAINTENANCE
Normal Operating Procedures
During the normal operation of the TQ System, a few items are required to be checked daily. Routine upkeep
with these items will maintain the operation of the TQ to its highest standards.
Daily Start-up/Shutdown
The equipment will run in an automatic mode, shutting itself off when the storage tank is full. Each time the
unit shuts down, the EverClean Rinse is set to flush each membrane with permeate water.
Daily Log
On the back page of this manual, a daily log has been provided. Photocopy this template and use it for
recording the system’s daily performance. By recording various system characteristics each day, this will help
in any future troubleshooting of the equipment. It is also necessary to keep a daily performance log to show
changing performance characteristics of the TQ System. These changes may be the result of membrane
fouling. With accurate logs kept on performance, timely cleaning of the membranes will insure maximum
membrane life.
The parameters included on the daily log sheet are:
Date
Feed Pressure (if an extra gauge is added)
Permeate Flow Rate
Water Temperature
Water Quality
Comments
Routine Maintenance
Filter Maintenance (Optional)
The inlet filter should be change at least twice per year. If
the filter becomes blocked, the dynamic pressure to the
membranes will be reduced, and the system’s performance
will be diminished. The system will not operate properly if
the inlet pressure drops below 40 psi for the wall-mount unit
(20 psi for cabinet unit). The cabinet unit does not have a
prefilter standard, so one must be added.
Check the daily log for changes in the inlet pressure if an
optional gauge is added. One can predict the life of the filter
before its use has become over-exhausted by using the daily
log as a preventative maintenance tool.
If a carbon cartridge is used with the system, then cartridge
replacement will become more frequent. The capacity of the
carbon cartridge is 1500 gallons, based on 2 mg/l of free Cl
2
.
Cartridge replacement must occur before exhaustion, or the
membrane will be damaged.
System Commissioning (Initial Start-up)
The start-up procedures for the equipment should be followed if:
-It is the first time the unit is being put into operation.
-The equipment has been moved.
