A glass of ocean water: Quebec company wins award for desalination technology

Wednesday, June 29th 2022, 1:43 pm - Oneka Technologies says its desalination systems can be powered solely by ocean waves and can deliver thousands of litres of clean drinking water.Just 0.5 per cent of the planet’s freshwater is available in lakes and other bodies of water and experts are warning that a water scarcity crisis is currently underway. Climate change is amplifying geopolitical tensions as lands turn to deserts, resulting in humanitarian crises amid the harsh conditions.

Oceans are the most plentiful water resource but salt water cannot be consumed by humans, which leads many experts to one solution: desalination.
Desalination technologies remove the salt from ocean water so it can be used as drinking water or for irrigation. Oneka Technologies, a company founded in Quebec, says that their technology provides safe drinking water with their all-in-one desalination system.The company is quickly gaining international recognition for their technologies that purify ocean water solely powered by the motion of ocean waves. The desalination systems are placed on buoys that are anchored 200 metres to three kilometres from the shoreline, a distance that was chosen based on wave height and sightline away from the coast.

A ‘pumping’ action occurs when the buoys rise and fall with the waves, which compresses the seawater and squeezes it through a reverse osmosis membrane. This results in concentrated saltwater being released back into the ocean and clean drinking water being sent to the coastline through an underwater pipeline that is connected to the buoy.
The smallest desalination system consisting of five buoys can produce 50,000 litres per day and larger systems of 100 buoys can produce one million litres per day.

I heard that Trinidad has a Deslination Plant in Point Lisas in Savonetta.
