Saudi Arabia: The leader in desalination technology Among the above-mentioned leading countries, Saudi Arabia is considered to be the most advanced country in desalination technology in the world because of its comprehensive leading position in desalination technology.

According to experimental data, the power consumption required for a 20m³/hr reverse osmosis device to operate for one day (24 hours) under ideal conditions is about 240 kilowatt-hours (kWh). This data shows that the power consumption per cubic meter of fresh water is about 0.5kWh,

The invention of desalination technology originated in the mid-20th century and was first patented by Alexander Zarchin. His desalination method is based on freezing seawater to form pure water crystals in a vacuum environment, which are then melted to create salt-free water. Chachin's invention laid the foundation for the early stages of desalination technology, but scientists and engineers produced many innovations in the field in the decades that followed.

Carlsbad's Poseidon ocean desal plant simply could not live up to its hype. It continues failing with production requirements, being subject to shutdown from red tides, while continuing to consume huge amounts of power, resulting in significant generation of greenhouse gasses.

Sea water desalination may be the key to avoiding global water shortages, but it will take time. Clean fresh water is vital to sustaining human life. However, seawater desalination plants also bring environmental pollution problems. The seawater desalination process produces waste and toxic chemicals that are harmful to wildlife and the earth.

Most cruise ship water is desalinated seawater. The process typically involves steam evaporation—essentially converting salt water into distilled water. The water is then mineralized for added flavor and chlorinated for improved safety. Other ships are equipped with reverse osmosis systems for filtration and/or desalination.

The cost of seawater desalination ranges between $5 and $10 per 1,000 gallons. This means that the cost per gallon of seawater desalination is approximately $0.005 to $0.01.

5 seawater desalination company stocks worth investing in 1. Ecolab (NYSE: ECL) 2. Consolidated Water Co. Ltd. (NASDAQ: CWCO) 3. American Water Works Company Inc. (NYSE: AWK) 4. General Electric Company (NYSE: GE) 5. Veolia Environment (OTC: VEOVY)

In large municipal seawater desalination plants, the cost of desalinating one cubic meter of water is typically around $0.50 - $1.00. The cost per liter of water is approximately US$0.0005 - US$0.001.

With much of the world facing freshwater shortages, one of the biggest benefits of seawater desalination technology is providing a reliable source of freshwater.
