Landbased Products
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.
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.
