SuperLogic 2500 Manual
An -Scalant Cartridge: Allows the system to be operated at a 2:1 product to brine recovery ra o by preven ng membrane fouling
due to hardness in the feed water. The system can also be specifi ed for a 4:1 product to brine ra o if a proper water so ener or
an scalant system is installed prior to the SuperLogic. Contact us for details @ (888) 426-5644.
Brine/Concentrate Recircula on Valve: A needle valve that controls the amount of brine from the membrane to be recirculated
back into the feed stream. This feature allows for higher recovery rates (lower waste water ra os). Addi onally, adjustment of
this valve regulates the pump discharge pressure.
Filter IN/OUT Pressure Gauges: Gauges that display the water pressure before and a er the sediment prefi lter. Used to observe
the pressure drop through the sediment prefi lter (a means of detec ng fi lter clogging or loading).
Flow Control: A fi xed orifi ce that controls the amount of water fl owing across the membrane to drain. This controls the ra o for
product water to waste water and either comes at a 4:1 or 2:1 ra o depending on how the system was specifi ed.
Low Pressure Switch: An electrical switch that shuts off the unit in the event of low feed water pressure. This is used as a pump
protec on device. This is factory set to cut off at 12 psi (0.8 bar).
Membrane/Vessel (Desalinator): Separates dissolved solids from the feed water. This assembly consists of a stainless steel pres-
sure vessel that houses the thin-fi lm, reverse osmosis (RO) membrane.
Prefi lter, Carbon: A 10 micron Eco-Green carbon block prefi lter that removes chlorine prior to entering the membrane.
Prefi lter, Sediment: A pleated fi lter that prevents undissolved par cles larger than 5 micron, from entering the system.
Product Water Check Valve: A one-way valve that prevents pressurized product water from fl owing back into the desalinator
(and possibly damaging the membrane) when the system is off .
Pump/Motor: The rotary posi ve displacement pump boosts water pressure in the desalinator up to 150 psi (10.3 bar) for low
energy membranes to ensure high solids rejec on and high fl ow rates.
Solenoid Valve: Electrically operated valve that prevents water from fl owing through the system when it is not in opera on.
Vessel Pressure IN/OUT Gauges: Gauges that display the opera ng pressure before and a er the RO membrane (used to observe
drop in membrane pressure indica ng fouling or clogging).
TDS Monitor: Simultaneously reports the feed and product water TDS in ppm. Includes op onal alarm func on. A low PPM limit
can be programmed so the system shuts down if PPM’s go above set point.
