Pure Aqua, Inc. designs and manufactures water treatment systems in addition to tap water RO systems. In January 2011, Pure Aqua, Inc. successfully manufactured four identical tap water RO systems to a major company in Bahrain. The four TW-1.5K-140 systems were designed to each produce 1,500 GPD at a maximum rate of 500 PPM TDS and came complete with a microprocessor control panel. The systems were chosen from our RO-200 series. For more information click here: http://www.pureaqua.com/reverse-osmosis-systems.html
