I need some assistance with these assignment. saudi arabia water challenge Thank you in advance for the help! It is evidently clear from the discussion that the oceans contain about 97% of the entire water on the earth’ surface. in Saudi Arabia, water has been supplied in three forms, mainly surface water, which accounts for about 10%, the underground aquifers that provide the majority percentage of more than 80%, and the various desalination plants, which provide about 5% of water. The availability of essential water supply continued to deplete and the water resources become limited, prompting the adoption of desalination plants. Natural resources define all the resources that occur freely within the environment that exist in a natural form, such as natural forests, minerals, water, and natural gases. Desalination refers to the several processes of conversion of salt water to fresh water through the removal of salt and other minerals. Several approaches are used to treat seawater including thermal evaporation of seawater and use of modern desalination plants, osmosis in reverse. Nanomembranes are filters made from organic polymers with less thickness that are used to separate the liquids and gases at the molecular levels. Such technology is also used in desalination of seawater, purification of polluted water, and the removal of carbon dioxide and other pollutants from exhaust gases. The modern technology adopted in Saudi Arabia has enabled the exploitation of underground water by companies such as Saudi Aramco, an oil company, and hence increasing availability of water in the country. In Saudi Arabia, there has been water scarcity because of the rising population, which led to the adoption of desalination technology through the development of modern polymer materials producing semi-permeable membranes, which allow selective passage of water and other ions. The technology is categorized according to content extracted (water or salt from the mainstream), the separation process, and the energy used in the entire process.
