Pure Aqua, Inc. designs and manufactures water treatment systems in addition to skid mounted reverse osmosis systems. In April 2011, Pure Aqua successfully manufactured and supplied a skid mounted reverse osmosis system to a major company in Bolivia. The system came complete with pre and post treatment consisting of multimedia and activated carbon filters, a UV sterilizer, and chemical dosing systems. It was pre-piped and wired all on one skid, controlled by one microprocessor control panel. The machine was designed to produce 9,000 GPD at a feed up to 5,000 PPM TDS. The BW-9.0K-640 was selected from our RO-200 series. For more information click here: http://www.pureaqua.com/reverse-osmosis-systems.html
