Normal Operation
If the system is not running and you do not know how it was shut down it is best to
assume it needs to be purged. Running the system on feed water with the pressure
relief valve for 20-30 minutes will clear the system of anything that would harm the
membranes.
As a general rule always open the pressure relief valve prior to either starting or
stopping the system. When the system is stopped let the membrane pressure drop to
zero before restarting.
When in doubt open the pressure relief valve.
Over the lifespan of the system is will become important to understand the systems
past performance. Many troubleshooting questions start with “how has the system
been running in the past” so keeping a log of performance will be very helpful.
Log Book
It is highly recommended you keep an accurate daily log (or at least weekly) of the
operating conditions. If any of the parameters change it may indicate that chemical
treatments or mechanical repairs are required. This is one of the best tools available
for troubleshooting any problems in the future.

An increase in membrane pressure may indicate membrane fouling.

A decrease in product water quality (higher ppm) may indicate membrane damage.

A decrease in product water production may indicate Pearson pump damage or
wear.
