The industrial separation process to achieve pure water from seawater. This article will show one of the separation processes of a mixture that is obtained in one of the Geo-spheres, the spheres being the biosphere, lithosphere, hydrosphere or the atmosphere. This article will be talking about the hydrosphere and the separation of one mixture that is obtained in this sphere, this mixture being seawater.

Hydrosphere

The Hydrosphere has many mixtures collected from it. The Hydrosphere is the sphere that all the earths water content is grouped into such as oceans, seas, lakes, rivers, ponds and streams. Many mixtures can be obtained from hydrosphere and be put through an industrial separation process to achieve various useful products such as pure water from the seawater that is obtained.

Collection

Sea water is collected from the ocean and pumped directly into various desalination plants along the coast line, the water being pumped in is taken directly out of the ocean before being put through the industrial sized distillation plants to be purified.

Physical Properties Of The Mixture

Seawater contains various substances and materials, this makes it harder to purify as there are many different physical properties that have to be accounted for. Seawater is 96.5% pure water and 3.5% other material,such as salts, dissolved gases, organic substances, and undissolved particles. Because of the high quantity of pure water within the mixture a majority of the physical properties are the same as pure water. However the other substances and materials within the mixture give influence on some of the properties, for example the boiling point of the mixture may be slightly higher or lower depending on the other substances in the mixtures. seawater conducts electricity,

How this is useful for separation

Because the boiling point of water is much lower then that of the salt and other debris in the water. The water can be boiled away from the salt and collected using a process known as Multi-stage flash distillation, where the sea water goes through many different heating stages. Because of the difference in boiling points the water can be evaporated away leaving behind the unwanted waste.

Physical Separating Process

One of the most predominant separation processes used in the desalination of seawater is known as Multi-stage flash distillation. This is simply done by collecting the pure water out of the seawater by passing the seawater through different stages of distillation. The reason why you can collect the pure water out of the seawater is because the water has a boiling point much lower than that of the other contaminants, this is required to know when using this technique to collect the pure water as it is what makes this process possible. During the separation process the water will be boiled until it evaporates leaving behind the unwanted waste.

Physical Properties of the Product

The product of the process is the pure water. Pure Water has several different physical properties, these being that water is a clear liquid with a freezing point of 0 degrees, liquid at room temperature and has a boiling point of 100 degrees, there is a wide range of physical properties for water also known as H2O.

Uses of the Product because of Physical Properties

Pure water is a highly sought after commodity as more than 90% of the human body is made up of water; a majority of the pure water produced in the desalination plants becomes a source of clean drinkable water. Some of the less common uses are for example; it can also be used in the manufacture of medicine to prevent contamination or laser cutting to stop the build up of residue after evaporation.

Impact on society

Desalination has had a huge impact on society as it most importantly allows us to have a reliable source of clean drinking water along with some of the less common uses. The production of pure water in Australia is primarily from desalination, the huge amounts of pure water required costs the Australian government on average $140 million per year 80% of which is primarily from Multi-stage flash distillation.

Impact on the environment

One of the major problems with the desalination processes used not only in Australia but worldwide is that it is a very power intensive process. This is a huge problem for the carbon footprint in Australia as a large majority of the power produced is from coal; this creates a large amount of greenhouse gasses and contributes to global warming. Along with the problem of polluting the air through the huge power usage, the water gets polluted from the excess salt and brine that gets released back into the ocean. The salt that is collected in the process is not economically viable to make other salt products from as it must first be separated from the brine and other waste materials such as sand, rocks, shells, etc. The other waste products along with the salt get pumped back out to sea, where if not done correctly can build up and harm marine life. The waste must be slowly added back into the ocean at a location where the ocean currents will effectively take and re mix the waste products back into the ocean at a normal level so to not cause any harm.
