Reverse osmosis provides the most cost-effective way of reducing salinity in water. Traditional Reverse osmosis can, however, be energy-intensive, though as a result of innovation Katadyne Group has developed Spectra Reverse Osmosis systems that are capable of providing fresh water from Brackish and Seawater at very low energy.
Spectra reverse osmosis come with Clark or Pearson high-pressure piston pump complete with an energy recovery system that recovers energy from the brine stream by channelling it to the underside of the pump piston, allowing recovery of 90% or more of the energy available in the brine stream, thereby reducing the energy input requirement by over 75%.
The systems are available in two series the Aquifer (AF) and the Land-Based (LB) series, and both series can be powered by DC or AC power, making them suitable for both solar power.
Features of the systems are as follows;
Pure Water treatment plants are specially designed for the production of totally pure water from the majority of natural or municipal sources, typical applications being bottled water production, institutional, commercial food processing facilities and manufacturing facilities requiring pure water in the production process. They eliminate most conditions of impurity including sediment, unappetizing taste or odour, and bacteriological contamination, the treated water output being to the highest consumption standards. Particular features include;
1.Five stage treatment that uses no chemicals providing simple operations and consistent pure water output at low operating cost.
2.Three sizes available – 500, 1000 and 2000l/h.
3. Supplied complete with all components as well as necessary auxillary accessories frame mounted to provide a compact, easy to install unit.
Though the main application is for bottled water production, the plants are also suitable for in-line filtration for a distributed supply and also bespoke plants can be designed and manufactured to suit specialized treatment requirements. With benefits of simplicity, economy and, most importantly, effectiveness, Akvo International Water treatment plants are the ideal solution for the production of totally pure water from the majority of semi-treated water sources.
