Pure Aqua, Inc. designs and manufactures water treatment systems in addition to green sand filters. In August 2013, green sand filters were delivered to a major company in Chile to lower the manganese and iron level in well water. The system came complete with tanks, top mounted valves, and high quality green sand media. Each was designed to produce 24 GPM.
