5 Essential Pros and Cons of Desalination

Desalination is the process of removing salt and other particles from seawater, brackish water and other waste water. This might seem like a necessary process in case of drought or population increases, but it is surprisingly a very controversial issue. People seem to have very strong opinions on the topic of desalination and its purpose. If the current infrastructure for water purification is ever compromised many feel that desalination makes it possible to have access to water that would be essential to survival.

List of Pros of Desalination

1. Reverse Osmosis Understanding
Reverse osmosis is one method of desalination that is very understood and backed up with scientific data. The technology used for this method of desalination is reliable and is designed to allow for high quality water that is acceptable for drinking. This means that using this method of desalination should allow for good results and could help bring an end to the water shortage crisis that we might be facing in the near future.

2. No More Water Crisis
Since there is so much saltwater in the ocean that is accessible, desalination could bring an end to the water crisis. The sheer volume of saltwater that is accessible is virtually inexhaustible. This means that desalination could bring and end to problems that we face due to droughts. We would always have access to the water heat was required for all basic needs.

3. Desalination Plant Locations
The plants that are needed to complete the desalination of saltwater will be located away from large residential areas. There are large plants that will be needed to make desalination possible, but they can be located in industrial facilities and would not put residential areas at risk. Having a plan in place for the location of desalination plants could be a way to make this safer long-term. Just one desalination plant has the ability to supply more than 500 million liters of water that would be suitable for drinking. This is a high amount that could change the way that we get water.

List of Cons of Desalination

1. Cost
Cost seems to always be an overriding factor with many controversial issues. The concept of cost effectiveness is not something that can be overlooked. Desalination can give access to higher amounts of suitable drinking water, but it is a process that is extremely costly. Desalination plants are needed to purify the water and remove the salt, but building and running these plants is not seen as feasible by everyone. Just one desalination plant requires high amounts of energy just to operate fully. This means that the total cost of desalination could be extremely high.

2. Greenhouse Gas Emissions
Those that are opposed to desalination also argue the concern that desalination plants could produce high amounts of greenhouse gas emissions. This means that the process of removing salt from saltwater could be very harmful to the environment and negatively impact the air that we breathe.

Coming to an agreement of the issue of desalination will take some time, but it is comforting to know that an alternative to freshwater does exist if needed. Weighing the pros against the cons gives you a new perspective on the topic.

Are We Running Out of Fresh Drinking Water?

Many experts are claiming that a water crisis is in the near future if precautions are not taken now. This is due to the fact that freshwater necessary for drinking is not in high surplus and is beginning to run out. This leaves the door open for desalination since there is so much excess saltwater in the oceans that can be purified and used. This process of removing saltwater was designed by scientists looking for a solution to the fresh water crisis. As technology continues to improve overtime the process of desalination can become more effective and efficient.

Why is This Not an Agreed Upon Issue?

You would think that the need for fresh drinking water would end the debate on the topic, but those opposed to desalination feel that this issue is more complex. There are a variety of methods of desalination that can be used and almost all have their own downsides. Distillation and reverse osmosis are the two main types of desalination that are normally used to remove salt from saltwater. Before you jump to a conclusion on the topic of desalination it is important to become fully aware of both sides of this issue. This means that you need to take a closer look at both the pros and cons before you come up with your own opinion. With more information you can make a conclusion that is based on the facts.
