In July 2013, Pure Aqua designed and manufactured a commercial twin alternating water softener with 30" FRP tanks, 30" brine tank and Aquamatic valves for a major company in Nicaragua. Feed water to the softener was well water. Its purpose was to lower the hardness in the water to drinking standards. Each softener produced 30 GPM and was controlled by a digital stager.
