Spectra Watermakers

Want to build on a beach or bay front home with no water? No problem!

Spectra Watermakers, Inc. has the solution. Spectra’s LB-400/LB-800 series can provide 400 to 800 gallons per day from salt or brackish water. The LB-400 is simple to use, easy to install, quiet, very energy efficient and it delivers 16 gallons (60 liters) of fresh water per hour.

Drilled a well on a site that came up brackish or salt water? No problem!

The Spectra Watermaker is ideal for use in dwellings on beaches and bays where salt water or brackish water is available. The system uses a special version of the exclusive Spectra Clark Pump™ High Pressure Intensifier that has been proven for over ten years in thousands of land based and marine applications.

  • Pearson Pump—the most energy efficient desalination pump on the planet!

  • Pearson Pump is integrated with Spectra’s exclusive oil filtration system for extended service periods.

  • Microprocessor based controller with keypad display to monitor and control all functions.

  • Readouts include digital based flow and pressure as well as filter condition and operational hours.

  • A conductivity controller monitors product water quality and automatically rejects poor product water on startup.

  • A high quality Burkert diversion valve with manual bypass is standard.

  • Tank switches can be integrated to automatically start and stop the system.

  • Motor speed control with external heat sink for total command over motor speed and product flow.

  • Three way valves and service ports integrated into the system for ease of maintenance.

  • Hand held salinity meter to check product water included.

The Spectra Clark Pump, unlike conventional systems, is a hydraulic pressure intensifier that derives its motive force for making water from a low pressure feed water source. The LB-400/800 utilizes a well pump to deliver the feed water and provide the power to desalinate water. Just one pump and motor in the well feeding the Spectra Clark Pump membrane module does the entire job. This makes for the simplest land based desalination system on the planet.

The LB 1800 and the LB 2800 are extremely energy efficient reverse osmosis desalination plants designed for stationary or industrial applications. They can treat high salinity brackish or seawater using just a fraction of the energy of conventional small plants. In fact, the Spectra LB machines are so efficient they are often powered from renewable energy. These units are built using Spectra’s revolutionary and proprietary new Pearson high pressure pump. The plants are supplied with a rugged stainless steel frame, Pearson Pump coupled to Spectra’s proprietary SpectrafluxTM membrane assembly, micro- processor control system with Burkert prod- uct water diversion valve, pre-filtration system, automated freshwater flushing system and a motor speed control for total system command. Touchpad display and controls are mounted in sealed enclosure. Service ports with three way valves are included to ease maintenance procedures.

  • 20 and 5 micron Spinring™ Industrial pre-filter set protects the membranes.

  • Water delivery and pre-treatment is site specific and will be engineered for your particular application.

  • Multimedia filters and ultra filtration options are available from Spectra.

  • Spectra engineered pressure vessels with proprietary Spectraflux™ membranes.

  • Totally enclosed fan-cooled motors for long service life.

  • Rugged 304 Stainless steel welded frame.

  • Integral tank and pump for automatic freshwater flushing of the membranes is included.

The Spectra Pearson Pump is a breakthrough reciprocating pump design. This unique high pressure pump combines feed stream pumping and energy recovery into a single unit. The “Energy Recovery” feature of the Pearson Pump takes the energy entrained in the brine reject stream from the RO membranes and recaptures it, dramatically increasing the overall efficiency. This results in bringing energy requirements down to an impressive 8-11 Watt Hours per Gallon (2.6 KWH per Cubic Meter) on seawater, a major improvement for small scale water desalination. The system does not require continuous monitoring and pressure adjustment, as it stays inherently in balance at all times, providing a constant product flow and recovery ratio. The product flow can be controlled via the variable speed drive to the motor. The Pearson Pump is manufactured from engineered composites and super duplex stainless steel for extreme corrosion resistance. Spectra’s innovative oil filtration system allows for long maintenance intervals.
