The concentration of each dissolved ionic species must not exceed the limits of solubility anywhere in the system. Pre-treatment must be sufficient to eliminate chemicals that would attack the membrane materials. A. SPECIFICATIONS R4X40-1 R4X40-2 R4X40-3 Maximum Productivity (gallons per day) 2200... -
Page 6: Overview
B. RO OVERVIEW Reverse osmosis systems utilize semipermeable membrane elements to separate the feed water into two streams. The pressurized feed water is separated into purified (product) water and concentrate (reject) water. The impurities contained in the feed water are carried to drain by the reject water. -

Prefilter Cartridge - Used to remove smaller suspended solids and trap any particles that may be generated by the other pretreatment. The cartridge(s) should be replaced when the pressure drop across the housing increases 5 - 10 psig over the clean cartridge pressure drop. The effect of suspended solids is measured by the silt density index (SDI) test. - Page 8 Figure 1...

D. STARTUP 1. Verify that the pretreatment equipment is installed and working properly. Verify that no free chlorine is present in the feed water. 2. Verify that the on / off switch is in the off position. 3. Verify that a filter cartridge is installed in the prefilter housing. 4. - Page 12 product water TDS. The meter will automatically turn it self off after a few seconds. The quality meter is powered by two AAA batteries. To replace the batteries, lift the meter out of the bracket and remove the back cover.
