Operation Specifications
It is imperative that the operation specifications laid out in this document are followed precisely.
The reverse osmosis process results in the concentration of filtered impurities and neglecting to follow
the operating procedures may cause the impurities to solidify and scale or foul the membranes. To
prevent this, your SZIII system should never be operated over the rated production or above the max
pump pressure of
150psi
. Note that the unit will shut off if the pressure exceeds 175psi. Water
temperature and inlet water ppm are variables that affect product flow and pump pressure.
Feed Water Specifications
Nothing has a greater effect on a reverse osmosis system than the feed water quality. The table
below shows the maximum and minimum levels allowed for the membranes used in this system.
CAUTION
The rated production will have to be corrected for temperature of the inlet water when determining
pg.
21 for an example on correcting the rated flow rate.
WARNING
DO NOT OPERATE THE SYSTEM BEYOND THE RATED PRODUCTION RATE!
DOING SO CAN CAUSE SCALING OR FOULING OF MEMBRANES.
NOTE
It is very important to meet the minimum feed water requirements. Failure to do so will
cause the membranes to foul and result in system underperformance.
