Desalination Using Plastic Sheets

Students use a saltwater circuit to test the efficiency of their model desalination plant and learn how the water cycle is the basis for the thermal processes that drive their desalination plant.

Desalination using plastic sheets.

The desalination system can be operated without interception up to 18 h by using phase change materials having melting temperature between 50 and 80 c which are available in market. Capacity related data was derived from the 2009 10 urban npr pp. University of illinois engineers are using molybdenum disulphide mos2 replete with nanopores for energy efficient desalination. This stores thermal energy during daytime then release heat in the night time and also maintains constant thermal energy output to the desalination system even.

A tape can be used to secure the tube inside the. Dig a pit that is about 4 feet wide and 3 feet deep. 7 8 and the water services association of australia wsaa report card 2009 10 p. In a study published in nature communications the illinois team modelled various thin film membranes and found that mos2 showed the greatest efficiency filtering through up to 70 per cent more water than graphene membranes.

The larger pot is sealed using a plastic sheet and a. If using a plastic tube run the tubing from the container to the outside of the pit. Students use a thermal process approach to design build and test a small scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. At inlet water is 62 c productivity efficiency and gor are 21 kg 63 and 0 53.

Even though we have a lot. Dig another small hole in the center of the pit and place the water container. A plastic tube a shovel and tape are optional. Supply capacity of large scale desalination and recycled water plants for major capital cities versus total urban water use 2006 07 to 2012 13 gl yr notes.

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. The steps for construction. 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. Brackish water is defined as having a total dissolved solids content of 1 000 mg l and saline water as having 10 000 mg l.

Solar desalination using humidification and. Solar water desalination has a long history. Effect of water temperature and height air flow rate and hole diameter is studied. Air bubble column achieves higher performance than that conventional humidifier.

Desalination is used to remove salts from brackish or saline surface water and groundwater in order to render it acceptable for human consumption or other uses.
