Pure Aqua, Inc. designs and manufactures water treatment systems in addition to commercial brackish reverse osmosis devices. In April 2010, Pure Aqua, Inc. manufactured and supplied five commercial brackish reverse osmosis devices to a major company in Dubai. The each commercial brackish reverse osmosis device was designed to treat well water with a TDS of approximately 2,000 ppm. These devices were selected from our RO-200 series and came complete with a microprocessor control panel. For more information click here: http://www.pureaqua.com/commercial-brackish-water-ro-200.html
