Spectra Watermakers Inc. (Spectra Watermakers), a US based manufacturer of reverse osmosis desalination systems, will introduce its new desalination product, the Pearson Pump. Pearson Pump is a high-pressure pump developed for energy-efficient reverse osmosis desalination of sea water and brackish water. This pump system joins the feed water pumping and energy recovery into a single unit.

The Pearson Pump is a breakthrough evolution and enhancement of reciprocating pump design.

The Energy Recovery feature of the Pearson Pump recycles valuable energy entrained in the waste stream which is normally discarded, recovering as much as 80% of the energy wasted in a conventional system. This dramatically boosts Spectra Watermakers’s efficiency, bringing energy requirements down to an impressive 10 watt hours per gallon, a major improvement for water desalination.

Spectra Watermakers ‘s Clark Pump energy recovery pressure amplifier, proven over ten years and in thousands of installations, features energy efficiency that enables the application of solar and wind power to drive many of their land-based products like the Solar Cube, which now produces 3,000 gallons per day with the Pearson Pump.

The development of the new Pearson Pump will allow Spectra Watermakers to increase the productivity of desalinated water by 30% in many of their existing products while also lessening their energy requirements and, due to the scalability of the Pearson Pump, the next generation of Spectra Land-Based and marine products will be efficiently producing 12-30 thousand gallons per day from ocean water and brackish water wells, river estuaries, and inland aquifers.

Solving the global clean water shortage is a huge problem that will need political will, vision, and technology, said Bill Edinger, chief executive officer of Spectra Watermakers, in a recent report. The production of the Pearson Pump is another important step toward affordable, dependable, and environmentally sound water purification.

The water supply in much of the most densely populated parts of the world is under great stress, from contamination and salt water intrusion and breakdown of an aging water distribution infrastructure. This problem and the associated issues are vast and complex, but part of the solution could lie within a decentralized non-municipal distributed water system of smaller plants.

Constructing a disseminated infrastructure is less capital-intensive and can be build on an incremental basis. This model is more easily powered by renewable solar and wind green technology, lessening the costs of energy transport and its associated infrastructure while also reducing its carbon footprint. Projects such as this are being built in developing countries and remote areas that may not have existing infrastructure and fewer regulatory hurdles; This localized concept has advantages that apply anywhere.
