Fossil Fuels are depleting fast all over the world. Various studies reveal that they are not likely to last more than 50-60 years. Only solution to the world energy needs and for that matter, the energy needs of Saudi Arabia can best be met with renewable energy sources. Solar energy is one of them.
Every company needs to do some planning and arrangements to run different business processes effectively and efficiently. The reason is that planning synchronizes the working of different processes of a company making it able to go in line with the internal and external business environments.
Desalination is a “technology that separates dissolved salts and other minerals from seawater or other salty water to provide clean drinking water” (Desalination: Fresh Water from the Sea, 2013). In fact, oceans contain 97% of the global supply of water and thus its immense source can be tapped in order to provide freshwater to a fast-growing world population (Desalination, 2013).
Saudi Arabia is a country that is mostly arid hence has very limited water resources that can effectively support all the activities in that region. The population of the country is highly on the rise but the natural resources are highly depleted. The problem with conventional desalination system is that the resources it depends on cannot be sustained for long-term water production.
Water is therefore a unique substance due to the fact that nothing else can be substituted for it. Nothing in this world is as universal and as necessary as water. It is needed for every aspect of human life. Since time immemorial water has been availed to everyone equally not dependent on class, religion or how deep one’s pocket is.
Desalination and Vapor Compression. Desalination refers to the processes used to remove salt and other mineral salts from saline water (Micale, Cipollina, & Rizzuti, 2009). Saline water gets desalinated in order to make water that is fresh for human and animal used.
Demineralization is a process involving dissolution of hydroxyapatite and diffusion of Ca and P ions towards the enamel surface with a consequence amplifcation in porosity and also the biochemical and properties of the enamel.Hypersaturation of Ca and P ions on the surface may also result in a re-precipitation of hydroxyapatite forming the intact superficial layer on the enamel surface Orthodontists have been consistently attempting to reduce the process of demineralization with limited success.
Membrane distillation has been used to concentrate fruit juices and for wastewater treatment, and many industries are interested in studying and applying it since it yields highly purified permeate and separates contaminants from
Despite such significance, it was only recently that the access to fresh water was recognised as a universal human right (“General Assembly Declares”, 2010). This was officially acknowledged in an attempt to further encourage the international community to increase
