AquaPro RO LC-3 Series
(1,500 to 5,400 GALLONS PER DAY)
The AquaPro RO® LC-3 Series RO system is a high performance water purification system designed by PureH2O, Ltd.® to operate from tap and brackish source water in The Bahamas and Caribbean Islands. The rugged, stainless steel RO assembly comes with full electro-mechanical controls for optimum monitoring and operation. Standard features include stainless steel membrane housings and high-pressure piping, inlet and outlet pre-filter pressure gauges, low-pressure switch with delayed auto restart, inputs for tank level and pretreatment interlock, adjustable reject recycle, permeate and reject water flow meters, permeate water check valve, inlet solenoid valve, membrane feed water pressure gauge, and adjustable reject valve.

Note: Do not operate with feed water that is microbiologically unsafe or of unknown quality without adequate UV or Ozone disinfection.

For complete technical specifications and operating information please contact PureH2O, Ltd.®

Individual membrane productivity may vary (± 15%). System be operated on other feed water with reduced capacity.

Percent rejection is based on membrane manufacturer's specifications; overall system percent rejection may be less.

All PureH2O, Ltd.® Residential and Commercial Reverse Osmosis Systems are warranted to the original purchaser to be free of defects in material and workmanship for a period of one year from date of installation. PureH2O, Ltd.® will repair or replace parts which are defective. Normal wear, accident, abuse, misuse, unauthorized alteration or repairs are excluded. PureH2O, Ltd.® will not be responsible for damages resulting from the improper installation or operation of a PureH2O, Ltd.® system by a third party. This limited warranty is effective only for installations completed by a PureH2O, Ltd.® For warranty issues please call 242-327-3541.

  • Pre-filter Housing NSF/ANSI Certified 42.

The AquaPro RO® LC-3 system should be installed after a PureH2O, Ltd.® water softener so that scale forming calcium and magnesium hardness cannot scale the RO membrane(s). A PureH2O, Ltd.® backwashing carbon filter should be installed on the RO feed water line to remove chlorine and prevent membrane degradation due to chlorine attack. A PureH2O, Ltd.® sediment filter should also be installed on the RO feed water line to reduce the silt density index of the water to prevent particulate fouling of the RO membrane(s).

This RO system is a low-energy type unit complete with permeate and reject water flow meters, pre-filter inlet/outlet and membrane feed water pressure gauges, 316L stainless steel membrane housings, automatic inlet solenoid valve, stain-less steel high-pressure piping, low feed water pressure switch, reject and recycle valves, storage tank level and pretreatment interlock inputs, micro-electronic controller, multistage centrifugal high-pressure pump, and all other components necessary for high performance operation.

The system is a wall mount design. The RO permeate water is collected in an atmospheric storage tank with the tank level controlled by an electronic level float. The RO system is equipped with inputs for the tank level float as well as pretreatment interlock to shut the RO system down in the event the pretreatment begins a backwash cycle.

Electrical requirements are 230 volt 60 hertz single phase. A local drain is required to accept discharge water from the system. The feed water pressure must not fall below 20psi. The feed water temperature must not fall below 35°F or exceed 100°F (2° - 38°C).

The system will produce reverse osmosis quality water with 98 percent minimum average ionic rejection of total dissolved solids when operated within the manufacturer's operational specifications.
