Solar powered RO Systems for sweet, brakish and salty water
Since RO systems becomes cheaper and easier to handle the latest developments are to combine proven photovoltaic technology (PV) with proven RO technology. The result is an economical solution that provides always clean water on a decentralised and renewable basis.
Small PV powered Reverse Osmosis desalination systems
- Up to 120 liters of desalined water per day
- Up to 280 liters of desalinated water per day
- Up to 500 liters of desalinated water per day
- Up to 1400 liters of desalinated water per day
- Up to 3500 liters of desalinated water per day
Brackish Water Desalination System TBW 6500
The Solar Treating Brackish Water System can provide from 3,500 Liters a day up to 6,500 Liters a day depending on the salinity of the feed water. It can operate in a feed water range from seawater down to a few thousand parts per million of salinity such as brackish wells and lakes. Utilizing a hybrid of technologies the brackish system can operate in a full range of conditions all the while maintaining the renowned efficiency.
Fresh Water Treatment System TFW 15000 IE
The Solar Treating Fresh Water System can purify 15,000 Liters of water a day from almost any non saline water source. The ultra filtration purification method removes virus and bacteria without the use of harsh or toxic chemicals. Ultra filtration technology is becoming the method of choice for municipal water treatment plants due to its long life and minimal maintenance. The TFW system is designed to operate in the most rugged and hostile conditions.
Different installations around the world with proven track record.
Water purification trailer
The water trailer has been specially designed for
- disaster relief
- military camps
- temporary application
The water trailer is equipped with a solar powered water treatment system for sweet water or a Reverse Osmosis system for salt water sources.
The system provides 7'000 to 15'000 litres of clean drinking water per day from any water source. Powered by renewable solar and/or wind energy it can run 24 hours a day without ongoing fuel and fuel transport costs.
The system produces extra energy for running different electric installations. It comes complete with trailer, borehole type delivery pump, an exclusive automatic back-flushing filtration, batteries, solar panels and controls.
An ultrafiltration membrane or a reverse osmosis system (for sea or brackish water) removes all virus, bacteria and salt without requiring toxic chemical treatment.
