SECTION 1
Equipment Description
The FORMULA Reverse Osmosis Drinking Water treatment system consists of three
components: the Reverse Osmosis filter assembly, the Storage Tank, and the Service
Connections.
REVERSE OSMOSIS FILTER ASSEMBLY
MODEL IDENTIFICATION:
The filter assembly consists of two 10-inch pre-filters in series, the
reverse osmosis membrane, the post-filter, and the auto-shutoff valve. Model II is a standard 15
gpd, Model III is a standard 25 gpd, and Model III+ is a modified 35 gpd.
PRE-FILTER: Table 1 shows the various configurations of suspended particle filters and
dechlorinating filters used in the FORMULA product line. The particle filters are used to prevent
damage to the Reverse Osmosis membrane and to prevent clogging of the flow control and
auto-shutoff valve. The dechlorinating filter is a carbon block filter, no fines carbon cartridge
containing approximately 4 million square feet of surface area. This carbon is capable of treating
approximately 6,000 gallons of water entering the filter with a free chlorine residual of 2.5 ppm.
The carbon filter is required to protect thin film membranes from free chlorine. Change the
carbon filter every year or sooner depending on your water supply and dealer
recommendations.
R.O. ELEMENT HOUSING:
The housing contains the reverse
osmosis membrane, which
is
the backbone
of the system.
The R.O. membrane element separates
the clean water at the
molecular level from the major
ity
of impurities and stores the “product”, or R.O., water in the
storage tank. The above impurities are concentrated in the waste or “brine” water and sent to
drain. The R.O. housing element is the large, white vessel mounted with two white “C” clamps.
POST FILTER:
The post filter contains activated carbon and is used solely for marketing
reasons after the water
leaves the storage tank. The post filter is white and mounted in front of
the R.O. element housing.
AUTO SHUTOFF VALVE:
Prevents water flow to drain when product tank is full.
