Quick Answer: Seawater reverse osmosis (SWRO) desalination is quickly becoming the go-to, climate-proof way to get water for coastal areas hit by drought. Modern SWRO plants make water for just $0.50-$2.00 per cubic meter. They do this by using smart energy recovery, membranes that reject a lot of salt, and often, renewable energy. Globally, we’ve installed systems that produce over 100 million cubic meters of water daily, serving more than 300 million people. AMPAC USA builds SWRO systems, from small 1,000 GPD units to big industrial ones producing over 50,000 GPD.

We’ve been using up fresh water so fast for so long, our natural water sources around the world are running dry. This is a huge problem. Things are especially bad in tropical and offshore areas; they’re facing severe water shortages.

Of course, people are trying their best to cut down on water waste. But even with all these efforts, water levels keep dropping. Why? Because we can’t just stop using water. It’s essential. So, in this tricky situation, seawater desalination has stepped up as the most practical answer.

The process uses reverse osmosis. A seawater desalination reverse osmosis plant has a few treatment stages. First, there’s pre-treatment. This stage removes solid impurities and helps your reverse osmosis plant last a long time. Next, high-pressure pumps and membrane elements purify the water, taking out salts and chlorides. Finally, we have post-treatment, also called polishing steps. These steps condition the purified water from the reverse osmosis process. This three-step approach ensures that ocean and sea water becomes clean and safe to drink.
