Freshwater From Seawater With Solar Based Water Desalination In Rural Areas
Solar water desalination is an effective strategy for converting seawater from the oceans into fresh water that people can drink. This technology is becoming increasingly popular in countries such as Saudi Arabia, where there are no year-round rivers, and in regions where clean drinking water is scarce.

Looking ahead to solar-based water desalination technologies that will transform the water industry

Elemental Water SourceTM plug-and-play solar desalination technology is a breakthrough innovation in the solar-based water desalination market. Companies are inspired by such advances and are increasing their research and development in the unique energy recovery technology for desalination of seawater, which consumes nearly 70% less energy than conventional desalination technologies.

Pillars of next-generation solar-based water desalination:
  1. HDH desalination: the solar-powered humidification/dehumidification (HDH) method is an efficient strategy for evaporating water from a saline liquid stream to obtain purified water. However, companies should focus on truly understanding the benefits of the HDH system using multivariable design optimization.
  2. CSP-based desalination: desalination based on concentrated solar power (CSP) holds promising potential to reduce the uneven geographical distribution of freshwater resources in different regions. To achieve this, companies are improving solar panels and developing hybrid CSP systems that are cost-effective.
  3. Membrane desalination: membrane desalination technology is becoming increasingly popular to solve water scarcity problems because it has lower energy consumption compared to distillation methods. To innovate this method, companies are experimenting with organic-hybrid and inorganic membrane materials, which can provide advantages such as useful chemical and thermal resistance, high flow rate and good selectivity.

Therefore, to excel in solar-based water desalination, stakeholders should collaborate with technicians and researchers to explore the possibilities of solar-powered thermal desalination technologies.
