1.0 DESCRIPTION E-CE Series Reverse Osmosis (RO) machines are durable pieces of equipment, which, with prop- er care, will last for many years. These instructions give operation and maintenance details vital to the sustained performance of the machine.
1.1.5 Membrane Elements Membrane elements are interleaved layers of semi-permeable membrane, spacer , and permeate carrier spiraled around a central permeate tube make up the mem- brane element. Figure 1.2 Membrane Element with Interconnectors 1.1.6 Clean-In-Place The abbreviation for Clean-In-Place is CIP .
C f = Feed Concentration C p = Permeate Concentration C c = Concentrate Concentration C avg = A verage Concentration in Machine 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.
4 Rejection = [(C avg ) - (C P )] x 100 (C avg ) = [(237.5 mg/L) + (8.3 mg/L)] x 100 (237.5) = 96.5% Passage = (C P ) x 100 (C f ) = (8.3 mg/L) x 100 (237.
1.2 Machine Nomenclature E-CE Series water purification machines are numbered in such a way as to indicate the permeate flow you can expect from the machine and other specifications: Example: RE, E8-CE-9, 400, 5, 66 - 75 1.
6 · Multi-stage centrifugal pump, SS construction (SS end castings and wetted parts, Noryl* internals) on the 3 to 3 to 34m 3 /hr and AS (all Stainless Steel components) on the 45m 3 /hr .
1.4 Specifications for E-CE Series Machines The machine flow specifications listed, T able 1.1 below , are based on 25 ° C (77 ° F) and 2000 ppm NaCl.
1.4.1 Feed W ater Specifications The feed water requirements listed in T able 1.1 must be met to ensure quality per- meate and extended membrane element life.
1.4.5 Reverse Osmosis Membrane Element Rejection E8-CE RO machines use Fiberglass Reinforced Plastic (FRP). E4H-CE RO machines use tape wrapped membrane elements.
2.0 INST ALLA TION The following installation guidelines will help you install your new E-CE RO machine. 2.1 Feed W ater Requirements The following feed water requirements must be met before installing your new E-CE RO machine to ensure quality permeate and extended membrane element life.
membrane element housings for removal and loading of membrane elements. If 1 14 cm (45-inches) are not available, the entire membrane element housing may need to be removed for membrane element replacement. 2.3 Plumbing The E4H-CE and E8-CE come with flanged connections installed on all isolation valves.
3.0 PREP ARA TION AND ST AR T -UP 3.1 Pretreatment for W ater 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 .
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.
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.
15. As the machine purges the air and fills with water , the pressure will gradually increase. W ater 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.
3.3 Daily Start-Up Check the machine to insure isolation valves are in the proper positions for operation. T o turn the RO ON, press the RO button so it is in the ON position. If the alarm light is lit, push the “Alarm Reset” switch on the control enclosure and the alarm button on the OIT .
4.0 MACHINE OPERA TION AND MAINTENANCE The operation and maintenance of a E-CE RO Series machine is relatively simple, but requires regular data recording and routine preventative maintenance. It cannot be emphasized enough the importance of filling out the Daily Log Sheet (Section 7.
flow and/or rejection of salts, or an increased pressure drop across the machine will indi- cate when cleaning is required. GE Osmonics recommends cleaning at least every month to assure good membrane element performance and long membrane element life.
reestablish normal operation. Operate the machine as described in the flushing section for at least one hour . The deter gent is sufficiently flushed when the per- meate conductivity is restored to its normal previous level. When conductivity is back to normal, divert the permeate and concentrate back to service positions.
2. Cut the bag open as close as possible to the seal at the end of the bag, so that the bag may be reused if necessary . 3. Remove the membrane element from the bag and remove the foam protectors from each end of the membrane element. 4. Remove the parts from the parts container (if included) and inspect.
4.6 Membrane Element Removal As time progresses, the efficiency of the membrane element will be reduced. In general, the salt rejection does not change much until two or three years after installation, when operated on properly pretreated feed water and routine maintenance performed.
5.0 FIELD INST ALLED ACCESSORIES 5.1 Pretreatment Shutdown E-CE Series RO machines are equipped with Pretreatment Shutdown control capability . Pretreatment Shutdown is the ON/OFF control of the RO via a signal from a remote device. External Control can be used when Permeate Flush is not desired prior to RO shutdown (Permeate Flush, Section 5.
centration of the diluted feed stream, at the operating recovery , is that the water in the machine at shutdown will have total dissolved solids (TDS) concentrations approximate- ly equal to the machine feed TDS level.
4. T urn the AUTO/HAND Button on the Pur ge Button located on the OIT to the “AUTO” position. W ith multiple remote devices wired in series, as described above, an open contact from any of the configured devices will activate the Permeate Purge Cycle.
6.0 TROUBLESHOOTING This troubleshooting guide can assist you in identifying common operating problems you may experience with your machine. The operator can easily correct many of these problems, howev- er , for those that persist or are not understood you should contact the GE Osmonics Customer Support Center .
