Pure Aqua, Inc. designs and manufactures water treatment systems in addition to commercial reverse osmosis packages. This package was shipped to Sri Lanka upon completion in May 2013 to be used to treat well water with 3,000 ppm tds. The water being treated will go through a series of pretreatments and post treatments before it is consumable. The pretreatments include prechlorination, multi media filtration, dechlorination and antiscalant dosing. Post reverse osmosis, the water will go through chlorination and pH adjustment.
