Project Title: An investigation of how the different variables in a desalination system can affect the amount of water collectedAn investigation of how the steepness of the copper pipes affects the rate of desalination in our set-up.
Desalination is the process of removing salt from seawater to make fresh water safe for drinking. Many countries are using desalination as a way of creating a more reliable water supply that doesn't depend on rain. Desalination produces drinking water and concentrate (the water that contains the salts that were removed in the desalination process, which is sometimes called brine). The dominant technology used in desalination today is reverse osmosis, which involves forcing water through semi-permeable membranes to remove salts and other impurities. The research we are performing will enable us to find out which angle of inclination is the most suitable to allow maximum water to be collected to in the short period of time.
It includes the independent variables which enables us to change the flow rate of water which will mainly be flowing through the copper pipes. We will also be able to change the amount of heat applied to the round bottom flask using the heating mantle which so conveniently enables us to change the heat.The experiment was conducted using the help of copper pipes, heating mantle, round bottom flasks and beakers.We used brass and aluminium pipes allowing us to bend them easily. The experiment was conducted under supervision of the lab techs.All tests and work was conducted in the research lab.
The flow rate of water has almost no effect on the results as the results are extremely minimal and cannot be depended on the flow rate of water to differ them. The temperature changes the amount of water greatly as the amount of water collected differed. The steepness of the pipes results whether the water will fall into the beaker at the appropriate angle.The optimum setting was 450°C and 50 ° with water setting to the lowest (#1)
For future systems, the amount of heat applied should be actively changed so that a greater amount of water can be produced.Moreover, further studies can be conducted over the surface area of the container containing the water affecting the amount of water collecting in the collection beaker.
