Q: How much water does the VectaMaxx™ RSR system produce?
VectaMaxx™ RSR systems use membranes each nominally rated for 1200 or 2400GPD. Actual
output will be dependent upon the factors explained above. In optimal applications (low feed water
TDS, feed water =25°C, you may expect 700-1000 (RSR1200) and 1600-2100 (RSR 2400) USG from
each membrane to be available over 24 hours.
Q: Can the amount of total water produced be increased?
Once the system has been set for optimal operation, the overall water available for consumption
over a set period of time will be increased by increasing the storage capacity. This will increase the
time available for the unit to produce water in off-peak hours (instead of standing idle), and more
storage capacity to be available in peak hours when water usage may exceed production capacity,
for short intervals.
Q: What is the standard warranty with the VectaMaxx™ RSR system?
Every VectaMaxx™ RSR system comes with a standard one-year limited warranty on all parts and
shop repair labour, freight excluded. See section 5 in this manual for details on components with
limited warranty coverage.
Q: What is the maintenance schedule for the VectaMaxx™ RSR system?
A good rule of thumb is to replace the pre-filter every month in commercial applications. Consider
changing them biweekly when in continuous use or when used with untreated water sources.
Dependent upon feed water quality, your membrane(s) should have a life expectancy of 1-5 years
.
More severe water conditions (iron, hardness) may shorten this significantly; soft water sources may
allow a membrane life of up to 8 years.
See Section 5.
Q: When should the membrane(s) be cleaned or changed?
If you notice gradually decreasing production from your system, differing taste to your drinking water
or water analyses indicate a rising TDS, it probably means that your membrane(s) are deteriorating
and is losing effectiveness. You may purchase a pocket or full-featured TDS meter from your dealer
- this is the best way to gauge your RO’s operation.
Where the RO is used as a pre-treatment for a process requiring water to exact standards, you
should adopt a regular ongoing sampling and testing procedure to ensure compliance, as product
water will vary with the quality of the RO feed water.
Section 2. Designing your Installation
Your reverse osmosis system is designed to operate with feed water quality parameters that fall in
a specific range. The lifespan of the membranes and the ability of the system to produce water in
the required volume will depend largely on the feed water that is delivered to the system.
2.1. Start with a Thorough Water Analysis
Every successful installation begins with a full analysis of the raw water source. Testing should
measure the following:
•
Total Hardness:
This measures the calcium and magnesium hardness in the water. Hardness
in excess of 6 grains/gallon (103 mg/l) must be pre-treated by softening. Failure to do so will
cause premature failure of the membrane through lime scaling.
•
Total Iron:
Iron is another common membrane foulant. Found in most water supplies, it's
particularly prevalent in supplies drawn from wells. In its ferrous state (Fe
+2
), it's soluble.
However, when it's oxidized to its ferric state (Fe
+3
), it's insoluble and forms a
