Conventional desalination plants work in either of these approaches – thermal or membrane. In the thermal process, seawater is heated till the water evaporates, leaving the salt behind. The evaporated water is cooled, collected, and made available for use.
In the membrane approach, seawater is passed through a semi-permeable membrane that takes in the salt. This approach is also energy-intensive but comparatively better than the thermal treatment.
Oneka’s approach to desalination is an improvement over the membrane approach. This is achieved by using buoyant machines that are anchored to the seabed and using a membrane system that is powered by the waves.
