Seawater Desalination

Exuma

Seawater Desalination has become the ideal solution to meet the shortage of fresh water in the world

https://www.ampac1.com/Ampac-USA-Seawater-Desalination-Catalog-2017.pdf

The desalination process is based primarily on a seawater desalination reverse osmosis process. Seawater coming into the Seawater Desalination watermaker goes through an extensive pretreatment process, then goes through a seawater desalination reverse osmosis process to separate freshwater from seawater, then freshwater goes through another extensive post-treatment process to improve taste, smell and color.

Finally, desalinated water produced by seawater desalination watermaker through final steps to maintain the freshwater free from bacteria and microbes and to ensure access to pure fresh water for the consumer as well to reach the World Health Organization (WHO) standards for Drinking Water.

All Ampac USA Seawater Desalination Systems are manufactured in USA using Genuine American Made Components, using best marine industrial practices.

Pre-Treatment Process:

Seawater entering the desalination plant goes through spin down screens filter to remove suspended solids and debris, then gets injected with oxidants and coagulators to purify sea water as in many parts of the world waste water is dumped into the sea, leading to the contamination of seawater. In this process, chemicals are added to the seawater to make algae, organic materials and particles bond together so they can be removed more easily in the filtration stage that follows. 

In the next stage, seawater goes through automatic backwash Sand Filters to catch all the suspended solids, algae and organic materials that has bonded together.

Then Seawater goes through Automatic Backwash Activated Carbon Filters to reduce color and smell, as well adjust pH level of seawater.

Finally the seawater goes through a series of 5 micron Sediment Filters to remove silt and fine particles that may be remaining after the pretreatment process.

Seawater Desalination Reverse Osmosis Watermaker Process:

The Seawater Desalination Reverse Osmosis Process also known as SWRO process starts with High Pressure Pumps that forces the pretreated seawater through a set of semi-permeable membranes at high pressure to separate the freshwater from the seawater.

The size of the Seawater RO membrane pore is .002 microns, which is about 1/100,000th the diameter of a human hair.

Post-Treatment Process:

After the Seawater Desalination Reverse Osmosis Process, Fresh Water goes through Activated Carbon Post Filters, to improve Taste Odor and Clarity, then through pH adjust post-filters, then finally, through an Ultra Violet sterilizer to ensure water is totally disinfected and pure. Chlorine is usually added where the water is stored to stabilize the fresh water produced.
