X-Series Membrane System
X – Series Membrane Systems utilize reverse osmosis technology to produce high purity water by reducing
contaminants such as dissolved minerals, particulates and organic impurities. X – Series Membrane Systems are
engineered using the highest quality components and materials for reliable operation and exceptional performance.
Our standard systems are available with product water outputs from 6 – 396 gpm (8,640 – 570,240 gpd).
X – Series Membrane Systems are offered with a variety of options such as pre– and post–treatment equipment, distribution pumps and integrated controls for a complete water treatment solution. X – Series Membrane Systems are skid mounted, pre–plumbed and pre–wired allowing for quick installation and start up. A variety of membrane types are available including low energy, brackish, sea water and low fouling, nanofiltration and ultrafiltration. Our engineers are available for consultation and to assist you in designing your next water treatment solution.
The following are just a few of the industrial
applications that benefit from the use of an
industrial membrane system:
• Boiler Feedwater
• Small Municipalities
• Chemical Manufacturing
• Electronics Manufacturing
• Metal Plating and Finishing
• Ink and Dye Production
• Ice Production Equipment
• Food and Beverage Production
• Bottled Water
• Deionization Pre–Treatment
Features Overview
SKID AND FRAME ASSEMBLY
Membrane systems are manufactured in a skid frame
design for ease of installation with minimum floorspace
requirements. X – Series Membrane Systems are
constructed of welded structural carbon steel tubing and
finished with corrosion resistant epoxy powder coating.
Stainless steel fasteners and hardware is standard for
added corrosion resistance.
CARTRIDGE PRE-FILTRATION HOUSING
Integrated prefiltration is standard on all systems.
SYSTEM PRESSURE PUMP
Standard pressure pumps are constructed with 304 / 316
stainless steel housings, as well as impeller and diffuser
stage assemblies. Pumps are equipped with TEFC motors
and wired for 230 / 460 VAC voltage, and rated for full
load, continuous duty.
MEMBRANE HOUSINGS
All systems feature membrane housings constructed of
fiberglass reinforced polyester (FRP) with 316 stainless
steel side–entry feed and concentrate ports. Standard
housings have a white polyurethane finish and are NSF61
rated. ASME code–stamping is available on all membrane
housings.
INSTRUMENTATION
All systems feature a complete instrumentation package
for optimal performance monitoring. Each of the
following instruments are panel–mounted and pre–wired:
• Pre– and Post–Cartridge Filter Pressure Gauges
• Pump Concentrate Pressure Gauges
• Inlet Pump Discharge Pressure Switches
• Permeate and Concentrate Electronic Flow Sensors or Rotameters
• Permeate and Feed Conductivity Monitor
• Temperature Sensor
• Pump Run Hour Meter
MEMBRANE ELEMENTS
Standard reverse osmosis membrane elements are high
rejection, thin–film composite (TFC) type, in a spiral–
wound configuration. Membrane elements are tested and
carry a one–year warranty against defects in quality and
workmanship.
SYSTEM CONTROLS
Operation of the systems are automatically controlled
through a comprehensive microprocessor controller
housed in a NEMA – 4X industrial electrical enclosure.
The control system also includes a pre–wired motor starter, operator switches, push–buttons, and status
alarm indicator lights. Standard systems include the
following isolated alarm conditions:
• Low Inlet Pressure
• High Pump Discharge Pressure
• High TDS
SYSTEM PIPING AND VALVES
All membrane systems are completely pre–plumbed and
installation ready. Sch80 PVC is used for all piping and
valves under 75 psig operating pressure. Higher pressure
piping and valves are constructed of 316 stainless steel
for the X2 and X3. The following valves are provided
as standard for accurate flow and pressure control and
convenient operation:
• Automatic Inlet Valve to Prevent Water Flow through the System During Shutdown
• Pressure Pump Discharge Throttle Valve
• Concentrate Valve
• Optional Recirculation Valve
• Automatic System Flush Valve for Prevention of Membrane Fouling and Scale Formation
• Inlet and Sampling Valves
• Individual Membrane Housing Product Sampling Valves
• CIP Ports for Use with Membrane Cleaning System
