Pure Aqua, Inc. designs and manufactures water treatment systems in addition to commercial RO packages. This package was completed in April 2013 and shipped to Jordan for use at a major hotel. The feed source is well water with an approximate TDS level of 3,500 ppm. After going through the prechlorination, multimedia filtration, dechlorination, antiscalant dosing system and finally the reverse osmosis, the water should be at about 100 ppm TDS. The reverse osmosis purpose is to remove dissolved solids and with this machine, does so with about a 97 rejection rate of solids.
