Simple solar water filtration system

Faculty of Mechanical Engineering, Ho Chi Minh City University of Technical Education has successfully researched and applied the filter system of saline water, alum, brackish water, pond water or dirty water . in rural areas of the Mekong Delta by solar God.

The device is shaped like a box made of zinc-coated corrugated iron, the bottom and the surrounding surface are covered with available insulating materials such as rice husk, sawdust, fiberglass . The top is covered with glass panels. set the incline throughout 3-5 mm thick. Absorbing plates made of aluminum copper . are stamped in grooves of 10 mm radius. Wick wires are placed in the grooves to bring water from the container into the filter device.

The principle of operation of the water purifier here is to use solar radiation to evaporate steam. Steam is condensed and removed for use. On average, the surface absorbs 1m ² each day, the average radiation intensity is 800 W / hour, the water filter device receives from 6 to 7 liters of clean water.
