    • Introduction to the System With vacuum distillation technology to realize desalination and purification, solar energy collected are working as the power source for desalination to produce fresh water. In vacuum environments, reduced pressure condition is small; water purification objective can be realized by separation of unpurified water in high temperature environment. Main Features 1. By taking a series of technical measures, corrosion 4. Motive power consumption is low. Motive power and sediment to the equipment are completely consumption for water delivery is very low in the low avoided or delayed. temperature and multi-effect device, only hundreds of 2. Pretreatment of input seawater is much simpler. It volts electricity (for producing vacuum environment is benefited from system operations under low and water suction pump) is required, solar electricity temperature. The sea water is only required to be system is optional, power station facility is not filtered by screen before flowing into the low required, which could reduce production cost greatly. temperature and multi-effect device; no acid-adding 5. High heating efficiency.

Adequate surplus capacity. At noontime, water ratio. production could reach 150% of the designed value; in 6. Safe and reliable operations. In the low early morning and nightfall, water production can be temperature and multi effect system, vapors inside the stabled at 50% of designed value. tube are to be condensed and the liquid film outside the tube shall be evaporated, even there is leakage on Desalination Tube the heat exchange tube as a result of pitting corrosion; as the vapor side pressure is larger than the liquid film side, high salinity water shall not flow into the produced water. Such similar failures in RO are avoided as the system adopts high reliable module design, it is much safer. The operational cost is very low, only around 5% of the RO system, and there is no additive agent. 7. Close production system, well control for the flow. 8. Sensors are fitted behind of each solar collection mirror of the solar desalination unit for auto sun tracking, it is simple but practical. 9. The dimension of the production equipment is small, more suitable for large scale production. 10. The fresh water produced is pure water that is Meeting WHO drinking water standard for direct drinking. 11. All type of natural water source can be treated. Seawater, Waste Water, Hard Water, Brackish river Water, Beach Well Water etc. 12. Solar Water Desalination System is applicable for household, island resorts, hotel, mining and factories, community and large town etc. It is User Friendly! ----------------------------------------------------------------------------------------------------------------------------- -------------------------------- Beijing Office: Tel: (86 10) 8627-5592; 8627-5625 Fax: (86 10) 5894 8640 E-mail: bj@witeamgroup.com Hong Kong Office: Tel: (852) 6527 7869 Fax: (852) 3010 3483 Email: intl@witeamgroup.com ----------------------------------------------------------------------------------------------------------------------------- -------------------------------- http://www.witeam.com.hk
    • Principle of Solar Seawater Desalination System 1. Seawater collection; 2. Filtering ( through screen); 3. Sedimentation; 4. Preheating (preheating pool or glass house); 5. Heating (parabolic vacuum tube focusing & ultrared heating and ultraviolet sterilization, temperature would reach 70-80℃); 6. Desalination (Rotate the parabolic mirror by focusing on the vacuum tank, the temperature would reach 100℃) . Fresh water and high salinity seawater shall be desalinated; 7. Cooling down by exchanging heat (high salinity seawater shall pass the preheating pool via pipeline, and cooling down by exchanging heat and preheat the seawater in preheating pool at the same time); 8. Export fresh water (the turbidity of the desalinated water is 0.5ntu, which meet WHO drinking water standard); 9. Discharge high salinity seawater 10.
