C = Feed Concentration f C = Permeate Concentration p C = Concentrate Concentration c C = Average Concentration in Machine avg 1.1.10 Salt (Ionic) Passage Ionic Salt Passage equals the percent of dissolved salts passed through the mem- brane element or 100% minus rejection. 1.1.11 Recovery Recovery equals permeate rate divided by feed rate and is expressed as a per- centage. For example, 75% recovery means that out of a given feed rate, 75% is produced as purified water (permeate). 1.1.12 Salt

3.0 PREPARATION AND START-UP 3.1 Pretreatment for Water Purification All systems will operate most efficiently on filtered water with a pH of less than 6.5 and a Silt Density Index (SDI) of 5 or below. If the machine is operated on higher pH water, other forms of pretreatment may be necessary. A water analysis prior to start-up of the machine is required. To minimize the chances of calcium carbonate, calcium sulfate, or other salt precipitation on the membrane element, GE Osmonics evaluates e

STEPS 1. Recheck the function and integrity of your pretreatment equipment. Ensure that your water softener, activated carbon filters, and iron filters (where applicable) have been leaked checked, back washed, and thoroughly rinsed for service before starting up your RO unit. 2. Attach the feed water pipe to the inlet of the machine. The standard connection fitting is a polyvinyl chloride (PVC) flanged connection. Refer to Table 2.5 (Connections) for connection sizes. 3. Check for leaks at al

It is also important to understand the relationship of these two valves, the pressure gauge, and your RO pump. The pump has a fixed amount of flow produced, and the valves are the control devices to distribute this fixed flow amount. The pres- sure gauge is an indicator of applied membrane element pressure a the flows set by the valves 8. Press the Fill Button on the OIT so it is in the ON position. Water should begin to flow through the machine at this point, but the pump will not start. Al

15. As the machine purges the air and fills with water, the pressure will gradually increase. Water should flow through the permeate and concentrate piping, viewed on the individual flow meters. If you do not see flow, turn the machine OFF and return to Section 3.2 (Initial Start-Up). 16. Gradually adjust the concentrate flow control valve. As you adjust the valve, watch the average pressure (P ) and the your concentrate flow meter. Adjust the avg valve until your concentrate flow meter disp
