1232 RO Operator Manual
SYSTEM COMPONENTS: Membranes
The
Membranes
are at the heart of the reverse osmosis process, and the number in use will vary
based on the 1232 RO model. These membranes are semi-permeable, allowing water that is
being purified to pass through it, while rejecting the contaminants that remain. The reverse
osmosis process uses these membranes to separate and remove dissolved solids, organics,
pyrogens, and submicron colloidial mat
ter from the water. The process is called “reverse”
osmosis since it requires pressure to force water across the membranes, leaving the impurities
behind. Reverse osmosis is capable of removing up to 95-99% of the total dissolved solids
(TDS), thereby providing safe, and pure water.
SYSTEM COMPONENTS: Pre-Filter; Particulate Filtration
Cartridge (1
0”, 5 micron filter)
DESCRIPTION:
A basic particulate filtration consisting of a 1
0” housing fitted with a
cartridge type filter element. These are specified to trap particulate
matter of 5 microns or larger at a specified flow rate. There is a post-
filter gauge to measure pressure drop that indicates filter clogging. The
filter housing is threaded for easy cleaning and filter element exchanges.
MONITORING REQUIREMENTS:
Daily:
Check pre and post-
filter pressure, and ΔP (
pressure drop
) across it while the RO is
running.
MAINTENANCE:
-
Replace filters every 30 days or as required if there is a ΔP (
pressure drop
) across the filter of
greater than 15 psi while the RO is running; whichever comes first.
-
When changing the filter, the inside of the filter housing should be wiped down with a clean cloth
using either water or a mild (
1%
) bleach solution.
