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 Vectapure™ RSX II system?
Every Vectapure ™ RSX II 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 Vectapure™ RSX II system?
A good rule of thumb is to replace the pre-filter every other month in commercial applications.
Consider changing them monthly 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.
Step 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 precipitate. Concentrations
in excess of .05 ppm must be pre-treated with an iron remover (concentrations > 2 ppm) or
