F. PRODUCT WATER QUANTITY AND QUALITY:
The R.O. Membrane Element requires a
specified amount of Feed Water flow in order to reject impurities. Less than required Feed Water flow
causes the R.O. Membrane Element to recover a high percentage of Product Water (ratio of Feed Water to
Product Water) and causes the R.O. Membrane Element to foul quickly. It is, therefore, important to
maintain the Feed Water Flow into the R.O. Membrane Element to prevent mineral build up fouling. If the
High Pressure Pump is damaged, do not operate the system until the Feed Flow problem is corrected.
The clarity of the Feed Water affects the R.O. Membrane Element performance. If the Pre-filtration
Section is not trapping the suspended solids, the R.O. Membrane Element quickly becomes fouled.
Always ensure that there are clean Pre-filter Elements and change them frequently.
Always use genuine HRO Pre-filter Elements as they last longer and are FDA approved. Non HRO
Pre-filter Elements are less efficient causing more frequent changing. This may lead to neglect and
fouling of the R.O. Membrane Element.
Sea Water (35,000 ppm TDS) applications operate at 850 PSI to gain optimal performance. Pressures
below 850 PSI cause low Product Water Production and poor Product Water Quality. The Operating
Pressure is correlated to the Feed Water Temperature, production rate, and Feed salinity.
When operating from typical 35,000 ppm TDS Sea Water and a Feed Water Temperature below 77
°
F /
25 C, the system may be operated at higher pressures not to exceed 1000 psi, in order to gain optimal
performance. With a Feed Water Temperature above 77
°
F / 25 C, the system must be operated at
lower pressures in order to prevent excessive Product Water recovery and fouling. There is a decline
in Product Water Quality with Feed Water Temperatures above 77
°
F / 25 C. This is natural and
expected with the Reverse Osmosis process, and does not indicate a problem.
Water Quality is higher than normal or the red light does not go out.
The system pressure is below normal. Adjust it accordingly.
The Feed Water Temperature is above 77
°
F / 25 C
The Feed Water Salinity is above 35,000 ppm TDS due to operation in a high salinity sea
The Brine Discharge Water Flow Meter is reading lower than normal.
Refer to the Brine Discharge Water Flow Meter troubleshooting.
A product water "O" ring within the R.O. Membrane Element Vessel requires replacement.
The R.O. Membrane Element has developed a hole or cracked product water tube. (This
also causes higher product water flow, and high product water salinity.)
