NEW ON BOARD Windside Wind Turbines for Professional Use with 30 years’ experience Finnish Windside Wind Turbines have been designed for the most demanding professional use in the harshest of environments. Completely self contained and automatic Windside Wind Turbines are operating in the extremes of climate. From the freezing Antarctica with its ice and snowstorms, to the heat and sandstorms of the Sahara Desert and to the wet, stormy and corrosive atmosphere of the Pacific Ocean. Windside wind turbines are in use in over 40 countries. WatMan SWRO S eawater Reverse Osmosis (SWRO) rejects typically 98.5–99.5% of the salinity in one pass. In large-scale production, energy consumption cre- ates a noticeable expense. In conventional SWRO systems, typical energy consumption varies from 6 to 10 kWh/m3fresh water, depending on salinity, temperature and recovery rate among others. In state-of-the-art systems with energy recovery the energy consumption can be as low as 2...4 kWh/m3-fresh water. On the other hand, 1-pass SWRO can produce fresh water with 100–150 mg/l of chloride at its best. These high rejection systems always need an average feed pres- Windside wind turbines have been designed for battery charging and can be used whereever energy is needed. The Windside uses are almost limitless be it safety telecommunication towers, remote signal and surveillance equipment, lighthouses, gas and oil platforms, ships and boats etc. sure of 55–70 bars. So called 2-pass SWRO can remove even up to 99.9 % of the total salinity, meaning 20–50 mg/l of chloride. These extremely high rejections are sometimes needed to spare the metal piping from corrosion. WatMan SWRO Systems can help you to produce extremely low-salinity fresh water with very low energy consumption. This means less energy, less maintenance, Oy Windside Prodcution Ltd is a member of IALA. Patented Technology. Read more: www.windside.com less down-time, less costs and more customer satisfaction. Less is sometimes more.
