Pure Aqua, Inc. designs and manufactures water treatment systems in addition to industrial sweater RO systems. In February 2011, Pure Aqua successfully manufactured and supplied an industrial seawater RO system to a cruise line in the Fiji Islands. The system came complete with pre and post treatments consisting of a multimedia filter, and chemical dosing systems. The SW-11K-1380 system was designed to produce 11,000 GPD at a maximum 36,000 PPM feed water TDS and is controlled by an advanced microprocessor. The system was selected from our SWI Series.
