Desalination Using Plastic Sheets

In this instructable i will show you how to modify a plastic bottle so that it can desalinate small amounts of water using heat energy from the sun.

Desalination using plastic sheets. Reverse osmosis desalination brine disposal. 3 1 2 water desalination using solar power. The funnel underneath the quarter is made from a plastic. Two plastic jugs are used as desalination devices.

Pure water condenses on a plastic cover and runs down the sides to be collected. Solar water desalination has a long history. The first documented use of solar stills was in the sixteenth century and in 1872 the swedish engineer carlos wilson built a large scale solar still to supply a mining community in chile with drinking water. For plants using other treatment technologies plastic piping and lining products are also utilized.

The first jug lays on its side with the top facing wall cut out. Plastic wrap covers the gap in the jugs wall and a quarter is placed on the plastic wrap to create a low spot where condensation can collect and drip down into a funnel. Since frost forms when leaf temperatures dip simply covering the plant isn t going. Pumping station in the pump station area pe 100 and pp pipes and fittings utilized up to a diameter of 500mm.

The illinois researchers are establishing collaborations to experimentally test mos2 for water desalination and to test its rate of fouling or clogging of the pores a major problem for plastic membranes. The smaller pot is placed inside the larger one and weighed down with a stone. Plastic seems like a good idea for frost protection but it s just too thin to provide any insulation to plants. Two pots one four times the size of the other and a plastic sheet.

In most cases the easiest way to get rid of the important brine flow 70 to 55 of intake flow is to discharge it in the sea via a brine outfall pipe. A simple low cost method to desalinate sea water by distillation is used in some countries where fuel is available. Mos2 is also a robust material so even such a thin sheet is able to withstand the necessary pressures and water volumes. It requires basic kitchen utensils.

Solar desalination using humidification and. The removal of salt or other excess minerals from water through a variety of methods.
