Reverse Osmosis Systems

Reverse Osmosis, or, “RO” works by passing water through a semi-permeable membrane to separate the pure water into one stream and the saline/brackish water into another stream. The process is called “Reverse Osmosis” because it needs pressure to force pure water across a membrane, leaving the impurities behind.

Most water contains “total dissolved solids” (TDS) , which is roughly the total inorganic mineral content of the water, and these are removed. The reverse osmosis membrane separates these dissolved solids, or salts and flushes them down the drain.

 RO membrane and the carbon block filter will reduce the lead. Carbon block filters use a lead-specific filter media combined with the carbon to reduce lead.

Yes. The RO systems are certified for cyst removal.

Yes and no. We have tested many of our systems for total bacteria counts over the years and have not found higher levels after the systems unless the systems sat for several days in between uses. However, in some cases, particularly if the source water is high in bacteria and/or low in chlorine residual, bacteria can grow. We also have Ultra-Violet Sterilizer Systems that disinfect water after it leaves the filter system, insuring water low in bacteria. The manufacturers state in their warranty information that the RO systems are designed to be installed on water that is disinfected or does not have dangerous bacteria such as e.coli.

The filters should be changed once a year. The membrane should be changed every 3 to 5 years depending on the TDS levels in the purified water.

This depends on the quality of the source water. Generally, if the water to be filtered is municipally-treated city water low in minerals, then less expensive carbon block filtration systems would be the best type. If the water is very high in minerals, then a reverse osmosis system or distiller that removes minerals, salts and chemicals may be desired.

In regular “Osmosis,” such as the process utilized by plants, water flows from a lower concentration of salts to higher concentrations. In “Reverse Osmosis,” the application of pressure greater than the osmotic pressure reverses the water flows from higher concentrations to much lower concentrations, producing pure water.

Frequently Asked Questions

We mean that water that has a total dissolved solids (“TDS”) over 500 ppm or hardness over 200 ppm. However in some cases, even water that is lower than 500 ppm of total dissolved solids may need treatment by RO if there is some inorganic contaminant that needs to be removed. For instance, many customers are using an RO system who do not want to ingest the fluoride that is put into their water. Other contaminants that can be removed by RO include arsenic, or lead or other dissolved inorganic substances.

GPD refers to ‘Gallons Per Day”. This refers to the amount of pure water that is produced by the RO in a 24 period. For example, 22-33 GPD would mean the RO system produced 22 to 33 gallons of purified water per day. 24 GPD sounds like a lot of water, but actually that means 1 gallon per hour. So for example, the RO tank holds 2 to 3 gallons of water. If you used a couple of gallons of water at one time, it would take the RO one hour to refill the RO tank. So having an RO system that can produce 20 to 30 GPD is important, in order to have a system that is adequate for the typical family or homeowner.
