  • Page 5: Description

    Figure 1 - Normal vs. Crossflow Filtration Osmonics manufactures a patented spiral-wound membrane package, with a turbulent flow design. This membrane module, called a sepralator, collects the purified water within a cen- tral tube, the permeate tube (see Figures 2 and 3).

  • Page 7: Principles Of Operation

    Some operating definitions are provided to help you further understand your machine: Permeate Rate [Product Water Rate (Q )] is the flow rate of purified water which has passed through the membrane and out of the sepralator; expressed in gal/min (gpm) or gal/hr (gph) [in metric, liter/min (Lpm) or cubic meters/hour (m /h)].

    Electrical The DLX and ECN E-Series models are supplied with a single-phase, 110 VAC 60 Hz or 220 VAC 50 Hz control circuit and 8-foot cord which plugs into a three-prong grounded receptacle. For 220 VAC, 50 Hz units, plug must be customer-supplied. A 20 amp dedicated service circuit is required for proper operation.

    If the machine is to be run at a different location than was originally intended, a new water analysis is required for warranty consid- eration and should be sent to Osmonics for review and recommendations for operation of the machine.
  • Page 16 3.2.4 Turn on the feedwater gradually and check for leaks in the inlet piping. No flow should go through the machine while the power is off and the inlet sole- noid is in the closed position. NOTE: When the machine is off, there should never be flow through the machine.
  • Page 17 Consult the Lakewood Model 2450 Installation and Operation Manual (P/N 1109695) for operating instructions. The factory alarm setpoints are as follows: Low Inlet Pressure 12 psig Low pH High pH pH Control 5.6-6.2 High Temperature 120ÞF (39ÞC) NOTE: The high-pressure pump should not be operating at this time. 3.2.11 As your machine is filling check for leaks and repair as needed.
  • Page 18 exceed 250 psi (17.3 bar). If you reach 250 psi (17.3 bar) before the valve is completely closed, open the recycle flow control valve one full turn, then continue to close the concentrate flow control valve. Continue to close the concentrate flow control valve until it is completely closed and your pressure is below 250 psi (17.3 bar).

  • Page 19: Operation And Maintenance

    Osmonics if a warranty question arises. OPERATION AND MAINTENANCE The operation and maintenance of your Osmonics E4H Machine is relatively simple but requires regular data recording and routine preventative maintenance. We cannot emphasize too strongly the importance of filling out the daily log sheet during each operating shift.

  • Page 20: Pre-Filter

    100 hours of operation, whichever comes first. A pressure drop of 8 psig (0.6 bar) across the filter or more during operation indicates one or more cartridges need changing. Use only Osmonics approved filters rated for 5 microns or less. Do not attempt to clean used filters - install new replacements.
  • Page 21 Osmonics recommends cleaning at least every month to ensure good sepralator performance and long sepralator life. Osmonics offers a full line of chemical cleaners for specific cleaning needs. See Table 2. Table 2 - Dry Chemical Cleaners...

    4.6.10 Insert the downstream end of the sepralator in the upstream end of the sepralator housing (i.e., load in the direction of flow; the brine seal is on the end of the sepralator that goes in last. For sepralator housings with the flow arrow pointing up refer to Section 4.6.12).

  • Page 25: Optional Accessories

    OPTIONAL ACCESSORIES Level Controls Float switches, pressurized storage switches or other level controls should be wired into the control circuit line prior to the switch on the unit. The following ensures that the inlet valve, instruments, and pump are not powered when storage tanks are full: float switch assembly with cord, counterweight, and plastic float (used with an atmospheric storage tank).
