RO systems are water purification systems designed for point of use drinking water. All RO systems in principle work the same, a series of filters, first and second stage are for removal of chlorine and other chemicals along with particles over 5 microns. The third stage is a Membrane filter that filters down to .0006 microns, mostly pure water molecules will get through this filter. Looks like a thick plastic wrap. In laymen terms we are forcing water through a layer that is semi permeable to reject contaminates and allow mostly pure water molecules to pass through. The water that passes through will have a rejection of 95-98% of all dissolved solids (contaminates), that leaves us with a very high quality water for drinking and cooking.
Residential Reverse Osmosis Systems make about 50 gallons per day and comes with a 2.5 gallon storage tank.
The differences in RO systems are the Quality of Filters and filter housings and level of service given to support the equipment. All of our RO and softener systems are built locally and we service everything we sell. We have not changed manufacturers in over 20 years. We believe we have the best value in softeners and RO systems in San Antonio and so do our customers.
