Pure Aqua, Inc. designs and manufactures water treatment systems in addition to reverse osmosis systems. In April 2011, Pure Aqua, Inc. designed and manufactured five identical brackish reverse osmosis systems to a major company in UAE to treat well water. The BW-1.5K-140 systems were each designed to produce 1,500 GPD at a feed water TDS of a maximum 5,000 ppm, they were selected from our RO-200 series and were controlled by a microprocessor control panel.
