Pure Aqua, Inc. designed a reverse osmosis water filtration system for use by a major company in Mexico. The filtration system included an RO system, activated carbon filter, two multimedia filters and two twin alternating water softeners. The RO system was chosen from our RO-200 series and was designed to produce 9,000 GPD. The feed source is well water with a TDS of approximately 2,000 ppm.
