Reverse Osmosis Water Filtration System 9,000 GPD - Mexico

Product Description

The way the twin alternating softener unit works is by having one tank remove hardness while the other is regenerating. The first tank is full of resin that is saturated in sodium ions. As water is going through the cycle, the resin attracts the calcium and magnesium ions that make the water hard. This then leaves the water with only sodium ions which do not have the same effect on soaps and detergents as calcium and magnesium ions have which leaves the water "soft". Once the first tank is full to capacity of taking calcium and magnesium ions, the tanks switch roles. Now the second tank will accept the role of removing hardness from water. The regeneration part of the process flushes a solution full of sodium ions through the tank, the resin now releases the calcium and magnesium ions and absorbs the sodium ions. This leaves the tank and resin in its original state again in order to repeat the process. The calcium and magnesium ions are discarded leaving the water soft and ideal for usage in hotels, schools, or restaurants.


Hardness in water does not allow soaps to work to their full capacity.
Hardness makes it difficult for clothes to be cleaned and leaves skin with a "slippery" feeling.



Pure Aqua, Inc. designed a commercial 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.
