Water desalination is the world’s most popular method for coping with growing water shortages due to population increase coupled with increased water use. Here’s how the technology works and where it is used:

Current Water Desalination Practice

At the moment the primary method of desalinating water is via the reverse osmosis method.  This pushes water under high pressure through fine membranes that separate the salt. It does work effectively but is not environmentally friendly as it uses high amounts of energy, the major cost and also a high level of consumables for eg filters, membranes.

As expected perhaps, the top three  water desalination countries are Saudi Arabia with 17 percent of global output, United Arab Emirates with 13.4 percent, and the United States with 13 percent.

In the oil rich countries of the Middle East, energy is cheaper and environmental regulations may be different to Australian, US and European requirements. The Middle East is where most of the world’s high-capacity water desalination projects are located.

In the US, 54% of water desalination occurs for processing inland brackish water. However, sea water, which accounts for just 7.4 percent and is more expensive to process, is being focused on increasingly with developments and growth as costs decrease and technology improves.

The Western Hemisphere’s  biggest water desalination plant is being completed in San Diego County in the United States. Due for completion by 2012, it will have an output of 56,000 acre feet per year.

With all water desalination plants there are environmental concerns that include the disposal of the brine byproduct that is much salter than ocean water. Thus it generally needs to be processed before being put back in the ocean.

Where insufficient water is the problem, there are reports of spending $650USD per acre foot for imported drinking water. Currently, places like Southern California pay $800 or more per acre foot – with that figure increasing also. In Southern California, desalinating seawater at major plants near to Construction areas, costs between $950-$1100 per acre foot.

Note: An acre foot is the amount of water it takes to cover an acre 12 inches deep. It is enough water to serve two four-person US households.


Breakthrough in Water Desalination Treatment

CLLEEN™’s Water and Power System is a unique operation and new method for desalinating water. It uses a self powered proprietary technology that means it requires NO fuel, No gas, NO grid electricity to run 24/7/365 – very environmentally friendly. And it is mobile.


CLLEEN™’s Water Treatment System can be applied to many circumstances including water treatment for Oil and Gas frac water, abandoned and active  mine discharge, desalination of seawater, treatment of underground water, used in humanitarian aid or disaster relief efforts, large scale desalination projects for town water supplies – the list is virtually endless.
