Landbased Products
The LB-1800 and LB-2800 are extremely energy efficient reverse osmosis desalination plants designed for stationary or industrial applications. They are supplied as modular kits to be installed in an existing building. There are three main components, the Pearson Pump module, the gauge flow meter panel and an electrical control box. Also included are prefilters and a basic installation kit. These systems can treat high salinity brackish water 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. Using simple analog monitoring and controls, these economical units are perfectly suited to remote applications that require the ultimate in reliability.
These units are built using Spectra's revolutionary and proprietary new Pearson High Pressure pump.
The 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 improve- ment for small scale water desalination. The system does not require continu- ous 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.
