GENERAL THEORY GENERAL THEORY OF OPERATION REVERSE OSMOSIS THEORY Reverse osmosis, like many other practical scientific methods, developed from processes first observed in nature. Osmosis is a naturally occurring phenomenon in which a semi-permeable membrane separates a pure and a concentrated solution (a semi-permeable membrane is defined as one that preferentially passes a particular substance).
GENERAL THEORY pressure on the unit above the recommended range) results in greatly increased membrane fouling rates and a significant decrease in the operational life of the membranes. It should be noted that no system is capable of removing all 100% of the dissolved solids from seawater.
GENERAL THEORY 3.4a TEMPERATURE CORRECTION FACTOR As previously described, the output capacity of any RO unit is highly dependent on feedwater temperature. In order to quantify this relationship, operational data has been utilized to develop Temperature Correction Factors (TCF). The TCF (which is compensated to 25°C/77°F) is used to determine what part of any change in system output flow is due to variations in feedwater temperature alone.
OPERATION OPERATION 4.1a TO START LITTLE WONDER FRAME UNIT Figure 51: Little Wonder FRAME Instrument Details. Step 1: Verify all power switches and power sources are in the OFF position. Step 2: On the sample valve, turn the valve to SAMPLE position to direct the flow of water to the sample line. Step 3: Turn the High Pressure Bypass Valve (Black Valve) to CLEANING POSITION.
OPERATION RO high pressure production should NEVER EXCEED 950 psi, doing so risks damage to RO unit, VOIDING factory warranty and may also risk personal injury. NOTE: At initial start-up of RO unit, keep the product water diverted from water storage tank. IF the unit is filled with preservative storage solution, water must be kept running AT LEAST 30 MINUTES to clear preservative solution from system.
OPERATION 4.2a TO START LITTLE WONDER FRAME 350 UNIT Figure 52: Little Wonder FRAME 350 Instrument Detail. Step 1: Verify all power switches and power sources are in the OFF position. Step 2: Turn the High Pressure Bypass Valve (Black Valve) to CLEANING POSITION. This procedure releases the high pressure air trapped within the system.
OPERATION 4.2b TO SHUT DOWN UNIT Step 1: When RO unit is running, turn High Pressure Bypass Valve (Black Valve) to CLEANING POSITION. This will release the high pressure in the system. Step 2: Press the HP PUMP pushbutton located on the Master Control Center panel of the electronic instrument panel, to stop the High Pressure Pump.
OPERATION 4.3a TO START LITTLE WONDER MODULAR UNIT Figure 53: Little Wonder MODULAR Instrument Detail. Step 1: Verify all power switches and power sources are in the OFF position. Step 2: On the sample valve, turn the valve to SAMPLE position to direct the flow of water to the sample line. Step 3: MODULAR UNITS (PRODUCED AFTER SEPTEMBER 1, 2003): Turn the High Pressure Bypass Valve (Black Valve) to CLEANING POSITION.
OPERATION Step 9: Observe the system pressure on the High Pressure Gauge. During RO production, the indicated pressure should be at 800 psi. If the pressure reading is not at 800 psi, adjust the nut on top of the back pressure regulator valve using a wrench until the reading reaches 800 psi.

MAINTENANCE MAINTENANCE The service life of most of the system equipment is directly related to the raw water inlet conditions. Improper maintenance will also significantly reduce the life expectancy of the major unit components (such as the membranes, filters and pumps) as well as the reliability of the unit as a whole. Under normal conditions, and with proper maintenance, a reverse osmosis membrane (which is the major consumable item) should have an effective service life somewhere between 4 and 6 years.

Rev. A 2/99 1 PLUNGER PUMP SERVICE MANUAL CAUTION: This is a positive displacement pump; therefore, a properly designed pressure RELIEF OR SAFETY VALVE MUST BE INSTALLED in the discharge piping. Failure to install such a relief mechanism could result in personal injury or damage to the pump or system.
Page 98
A reliable Pressure Gauge should be installed near the discharge outlet of the manifold. This is extremely important for adjusting pressure-regulating devices; and when appropriate, for proper sizing of the nozzle or restricting orifice. The pump is rated for a maximum pressure; this is the pressure at the discharge manifold of the pump. A Pressure Regulator or Unloader Valve must be installed to prevent over pressure in the event the discharge or down- stream plumbing becomes plugged or is turned off.
