<h5>What is seawater desalination?</h5><p>Most of the Earth’s water is unfit for human consumption as it has lots of salt. The majority of this is seawater. Desalination is the process by which salt and other particles are removed from seawater to make pure water that humans can use. Desalination can help provide a sufficient quantity of freshwater for drinking, home, industrial usage, etc.</p><p>Desalination can also help provide water in places with less freshwater. However, the major disadvantage of seawater desalination is its high cost, energy needs, and environmental impact, such as disposal of the generated waste.</p><p>The high energy requirements of present desalination methods will increase greenhouse gas emissions, affecting the climate. Despite these disadvantages, desalination is expected to increase due to increasing demands like population growth. So, new ways are being researched to make seawater desalination environment-friendly.</p><p>Recently, a company has created a new seawater desalination technology.</p><h5>Which company has created a new seawater desalination technology?</h5><p>Oneka Technologies, a Canadian start-up, has created floating desalination systems that can use the power of ocean waves to convert seawater into drinking water. They are of different shapes and sizes for various purposes. These machines are not dependent on fossil fuels. So, they provide a sustainable solution for water-scarce places around the world.</p><h5>How does Oneka’s desalination technology work?</h5><div class="raw-html-embed"><figure> <iframe width="100%" height="350" src="https://www.youtube.com/embed/Cab2znx2cnc" title="Oneka Technologies - How the technology works" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen=""></iframe><figcaption>A video on the new machines created by Oneka Technologies.

They use a membrane-based technique powered entirely by the movement of the waves. The machines absorb wave energy and convert it into mechanical pumping forces. Using it, the machines power the membrane-based desalination technique, which moves seawater through a semi-permeable membrane that collects the salt.</p><p>The method used in typical desalination plants doesn’t use renewable energy resources, contributing to carbon dioxide emissions. It also generates a waste stream of highly concentrated salt water or brine. If this is not properly diluted before being discharged back into the sea, it can affect marine life.</p><p>Oneka’s machines don't use fossil fuels, and the clean drinking water produced by them is pumped to land via pipelines and uses the power of the waves to do so. The brine created by the machines is diluted properly and released back into the ocean. This reduces its salinity and doesn’t harm marine life.</p><p>The company hopes to start selling the machines commercially from next year. Desolenator, a Dutch company, is also using solar energy for seawater desalination through a different method. The company doesn’t discharge brine into the sea. Instead, it gathers all of the salt for commercial purposes.</p>
