Desalination Using Plastic Sheets

Two plastic jugs are used as desalination devices.

Desalination using plastic sheets.

Two pots one four times the size of the other and a plastic sheet. Mos2 is also a robust material so even such a thin sheet is able to withstand the necessary pressures and water volumes. 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. 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.

It requires basic kitchen utensils. Since frost forms when leaf temperatures dip simply covering the plant isn t going. Plastic seems like a good idea for frost protection but it s just too thin to provide any insulation to plants. For plants using other treatment technologies plastic piping and lining products are also utilized.

A simple low cost method to desalinate sea water by distillation is used in some countries where fuel is available. The smaller pot is placed inside the larger one and weighed down with a stone. Today s modern seawater desalination plant swro utilizes many plastic products manufactured by agru. 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.

Pumping station in the pump station area pe 100 and pp pipes and fittings utilized up to a diameter of 500mm. Solar desalination using humidification and. The first jug lays on its side with the top facing wall cut out. Reverse osmosis desalination brine disposal.

Brine disposal is a real environmental problem that should be considered and studied when installing a desalination plant. 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. Live aboard sailboats have emergency seawater stills that use sunlight to evaporate pure water from seawater. Solar water desalination has a long history.

Pure water condenses on a plastic cover and runs down the sides to be collected. The funnel underneath the quarter is made from a plastic.
