The Impact of Water Scarcity on Regions

Water scarcity has become a serious issue over recent years. In the Middle East, where the desert sun beats down mercilessly, access to fresh water is as precious as gold. For instance, desalination provides a whopping 42% of the United Arab Emirates’ water needs. That is like trying to fill your swimming pool with bottled Evian.

In Saudi Arabia too, they are feeling the heat – and not just from their spicy cuisine. The need for clean drinking water there is critical.

But let’s journey across continents for a moment. South Africa has its share of parched surface waters and dry wells too due to lack of access to clean water sources.

  • Some statistics:
  • According to projections by the UN, by 2030 it’s estimated that between 75 and 250 million people will be living in ‘water-stressed’ areas across Africa.
  • If you thought being stressed about your Wi-Fi signal was bad enough… imagine stressing about every drop you drink or use in your manufacturing process.

Water shortages are indeed real, but don’t fret; solutions are at hand.

Solution Spotlight: Desalination in Action

A growing number of regions around the world are turning towards desalination infrastructure as an integral part of their water supply strategy. Utilizing reverse osmosis desalination technologies to transform saline water into a reliable clean water supply.

Desalination as a Potential Solution

Water scarcity is a pressing issue that requires urgent attention. Desalination technologies, such as seawater desalination, offer a potential solution to this problem.

Reverse Osmosis Desalination Technology

Reverse osmosis technology is at the core of many desalination plants. This process involves the use of pressure to separate saltwater into freshwater using specialized membrane filters. The Middle East has been utilizing this method for a significant period, effectively transforming their vast oceans and seas into freshwater sources. The UAE is heavily reliant on reverse osmosis systems to meet almost half of its water needs. Learn more.

Waste Brine Management

One challenge associated with seawater desalination is the management of waste brine. While saltwater is converted into freshwater, there is a byproduct of waste brine that contains concentrated salts and trace chemicals. If not handled properly, this waste brine can harm marine life. However, companies like Genesis Water Technologies utilize specialized diffusion systems to maximize brine dispersion to dilute the concentrated brine to mitigate the effects on aquatic life. 

Additionally, scientists have discovered innovative methods to convert certain waste brine into marketable compounds, offering a sustainable solution to this issue.

Hybrid Energy: A Ray of Hope for Desalination

Solar energy and waste to energy solutions are becoming increasingly utilized as part of a hybrid power supply to power desalination plants.

The hybrid power configurations can be used to drive entire operations, reducing greenhouse gas emissions associated with fully conventional power supply sources.

The Power of Semi-Permeable Membranes

Innovations around semi-permeable membranes have been game-changers in providing fresh water through desalination. The heart of any reverse osmosis system, these thin layers play an integral part by letting only water molecules pass while rejecting salts and other impurities. Research continues to show that optimizing their efficiency will lead to higher quality water production at lower operating costst

Case Studies: Regions in Urgent Need of Desalination Infrastructure

Desperate times call for innovative measures. In the face of water scarcity, desalination infrastructure is being utilized in regions such as the United Arab Emirates and South Africa to address their urgent needs. These efforts are akin to a parched traveler finding an oasis in the desert.
