  • Description

    With water becoming a critical resource in certain areas of the world, scientists have developed a new way to get pure drinking water from the sea.

    SYNOPSIS: The scientific theory behind the unit is called reverse osmosis, one of the simplest techniques available for water treatment.

    In this demonstration, water from San Francisco Bay is pumped up, put through one filter to screen out the larger suspended solids, and then enters the Polymetric Seawater System.

    Polymetrics President, Terry Dupee says the heart of the device is a semi permeable membrane made up of thousands of microscopic hollow tubes. This "hollow fiber" membrane lets the water pass, but rejects most impurities---and the salt from the sea. When tested, the product water has less than 500 parts per million total dissolved solids.

    And so a new company, less than 10 years old, solves a problem that has intrigued scientists for a long, long time.
