Short Essay On Desalination

757 Words4 Pages

Desalination is a very crucial process since it allows the extraction of dissolved salts from water, hence leaving us with fresh and clean water that are entitled for many uses. As you may know, 97.5% of the worlds water is seawater, whereas only 2.5% is fresh water. Due to this, desalination comes in handy for many reasons; one being the fact that the worlds increasing population is always in need of clean safe drinking water as it is essential for survival, and salty water harms the human body. Since the concentration of salt in a human body is 75% less than sea water, if it were to be swallowed it would notably increase the concentration of salt in the blood. Propitiously, our body cells consist of biological membranes that act as a barrier to prevent salt from diffusing into our cells. Even though, our bodies are able to regulate sodium concentrations to a certain extent, salt water forces the body to work harder in order to get rid of it. Moreover, if you have a high intake of salt water, you will lose more water causing dehydration to help dilute the surplus salt you have taken in; therefore making you more thirsty.

Farmers use tons of extra gallons of water on crops than is actually even needed. In California farmers take almost 70% of all water taken from the colorado river which happens to supply fresh water to all the states in the mid west.

  • Essay On The Effect Of Temperature On Osmosis

    Exploration Title: Effect of Temperature on rate of Osmosis Submitted By: Abdulkarim Kamal Date Submitted: October 19th 2015 Subject: Biology HL Teacher: Mr. Nick   Aim: This is an investigation to determine the relation between temperature of a solution (sucrose) and the rate of osmosis Scientific Context: Osmosis is defined a passive transport process in which a fluid diffuses across a semi-permeable membrane, from an area of high solute concentration to an area of low solute concentration and vice-versa. There are various factors that could potentially influence the rate of osmosis; these factors include volume, concentration, and temperature. If all external factors that may interfere with rate of osmosis are controlled, the results will show equal amounts of fluid on both sides of the barrier (membrane); this is known as an “isotonic” state.
