Preventative Maintenance Standards:
To be able to properly service and maintain RO membrane systems it is important to
understand the system history, so the fi rst time a unit is serviced there should be a system
history card fi lled out and attached to the machine. Knowing what the settings were after
the last service will be very helpful in understanding what is required for service in the
future.
PM Requirements -
Follow the procedures in this manual and,
Quarterly:
Change all pre-fi lters and o-rings
Clean
fi
lter
housings
Inspect system for leaks
Check all system operating pressures
Check
membrane
production
Check membrane water quality
Record all information in a system history log
Annually:
In addition to above, sanitize all fi lter housings with Kay-5
sanitizer (one packet to 2.5 gallons of warm water) or similar product.
Follow standard sanitizing procedure, clean with mild detergent, rinse
with clear water, fi ll fi lter with sanitizer solution, and allow to air
dry
or
reassemble.
Do not rinse the parts after sanitizer solution.
Inspect the tank for any algae growth and clean with Kay-5
sanitizer
if
necessary.
The Need for Pre-Treatment:
RO pre-fi ltration should be a combination of sediment ,carbon fi ltration, and water
softening The sediment fi lter brings the feed water NTU value to < 1 and the carbon fi lter
further reduce the sediment & turbidity levels in your fi lters reducing chlorine, chloramines
and VOC levels in the water down to acceptable levels. Because of the high recovery
of the pumped RO systems we highly recommend the use of a water softener ahead
of the reverse osmosis system. This will greatly increase membrane life and reduce
maintenance costs of the RO system.
