Solar Stills Water Purification

These devices absorb heat from sunlight and use it to evaporate water.

Solar stills water purification.

Sunlight enters the box and heats the water promoting evaporation. A solar still is an artificial water purifier that imitates the natural mechanism used by nature to purify water. The design is simple and elegant while still providing a powerful practical application. In areas where clean water isn t easily accessible solar stills can help purify available water that might be dirty or salty.

Directions to make the solar still. A pan of water is placed inside and the device is placed in the sun. Heat the water and the process speeds up. Like the natural hydrological cycle the sun drives the process of purification.

To make a solar still of this type you ll need to make a box out of plywood. When the water vapor hits the glass it condenses on it running down the glass to a catch tube. Solar still makes potable drinking water from salt water. They are used in areas where drinking water is unavailable so that clean water is obtained from dirty water or from plants by exposing them to sunlight.

In a solar still seawater dirty water or even green leaves are set inside a transparent plastic container which can be as simple as a polythene bag.

This can be used in arid coastal regions all over the world to produce potable drinking water for those in need. Tear open pack for emergencies. Water purification from solar energy no power required. With just a few basic building materials a sheet of glass.

The reverse osmosis system consists of two photovoltaic solar panels that power a set of pumps that push both brackish well water and collected rain water through semiporous membranes that filter. The sun evaporates dirty water which is then cooled and collected in pure form.
