Ways water desalination can become greener and more economical for your business

Water scarcity is a problem that not only affects South Africa but the entire globe.

Although water scarcity is not a new term, the issue has increased over the years, mainly because of climate change and a growing population. This is why it is so vital that water solutions are created and continue to be fine-tuned. Improving current water technologies will ensure that the treatments are still doing their job to help the environment rather than cause further harm.

When it comes to water scarcity, many industries have proven to be part of the problem. They use large quantities of water, and in most cases, the wastewater isn’t handled properly. This water tends to find its way back into the environment and affect alternative water sources, causing water pollution. This is why many sectors are now moving towards water technology that can help treat their wastewater during their manufacturing processes. These treatments ensure that the demand for potable water is not being compromised because of industrial processes.

One commonly used water solution is water treatment desalination. Water desalination has become a popular method, which includes the removal of salt and minerals from seawater to make fresh drinking water. The water desalination treatment process is an effective alternative for businesses which need water during processes.

Desalinated water is safe to use because it is monitored and goes through quality filtration systems to ensure the salt has been dissolved. However, desalination technology has a few negative qualities. For starters, desalination is expensive; it is an electricity-hungry process and, the brine produced during the process can be harmful to marine animals.

However, because of technological improvements, there are ways to make desalination water greener and more economical. To find out how desalination can become greener read the following article down below.


The throughput needs to be increased

Reverse osmosis (RO) is a common desalination method that has dominated the business sector. RO is a water treatment process that removes contaminants from water by using pressure to force the molecules found in water, through a semipermeable membrane. During the membrane process, the contaminants are filtered out and washed away. Thus leaving clean water.

Although it may sound like the ideal treatment, there are challenges that make RO a risk. The main problem with reverse osmosis is that the process uses large amounts of electricity, and the membrane degrades at a very rapid pace because of the mineral properties. This is a huge issue as this process is costly for businesses and also causes strain on the environment.

To ensure that this process becomes more environmentally-friendly, you must use membranes that are made out of inert hydrophobic material. The inert hydrophobic material is sustainable, durable and can be used for several more years. Another advantage is that the material can be recycled at a low price. Not only is this cost-effective, but it is also safer for the environment.


Reducing high energy consumption levels with heat recovery elements

As mentioned previously, desalination plants use a lot of energy when dissolving salts. New improvements need to be made during the processes, by including internal heat recovering, and replacing it with effective ways to transfer heat. The boiling temperature will have to be reduced to 80°C or less. Freshwater will be recovered through the cool vapour that is produced.

The water with the salt remains will transfer to a lower pressured cell. While the saltwater is in the low-pressure cell, the water will be preheated, and the remaining saltwater will be vaporised. This method won’t use additional power as the vapour will be cooled off during each stage, resulting in more potable water. This process also has a lower carbon footprint compared to a traditional thermal system.


Treating saltwater

During desalination, salt and molecules are filtered out to ensure clean drinking water. The only problem with that is that brine then goes back into the sea and can cause further harm to the ecosystem. But because of water technology, reverse osmosis was implemented and produces less brine. Although it may take time to find a method that isn’t harmful to the environment, this is a step in the right direction for your business and our planet.


In conclusion

Water treatment plants must be improved to operate with the most efficient equipment and state of the art technology. When treatment plants start slacking, they can have severe implications not only on the environment but on your business as well.

Outdated plants can become costly to operate and may take longer to get the job done. This will cause higher operating costs and lower revenue generation. So, to ensure that does not happen, the treatment plants need to be assessed regularly and taken it from there. By doing that, greener and more economical desalination plants can be achieved. This will make desalination a common practice with little to no negative implications.
