Residents of San Antonio insist that their drinking water be fresh and clean, and one way to make sure of this is through reverse osmosis, which filters harmful chemicals and pathogens from drinking water. Our professionals at Simple Water Softeners are pleased to install this system for both our commercial and residential clients.

Diffusion is the key to a reverse osmosis system. In an RO system, the molecules of water move though membranes from a higher to lower concentration. The reverse part is because the fresh water does not pass through to dilute contaminated water, but leaves contaminated water to replenish water that is already fresh. The membranes in a good RO system tend to block substances with a molecular weight above 100 grams per mole. Since water has a molecular weight of only about 18 g/mol, it can go through the membrane more easily than the sometimes very large molecules that make up chemicals and far more easily than viruses or bacteria. There are even some RO membranes that block ions such as calcium, sodium and chlorine whose molecular weight is less than 100.

Other contaminants that can be treated with RO are:
• Arsenic
• Nitrates
• Nitrites
• Fluoride
• Copper
• Lead
• Inorganic mercury
• Radium
• Uranium
• Some organic pesticides

Filter membranes in most RO systems are made of polymers or cellulose acetate and are about .25 microns thick. A micron equals one millionth of a meter, so these filters are very fine. They can be arranged in several configurations including being wrapped around a perforated tube or placed in layers before they’re enclosed in some kind of housing.

Before the water passes through a membrane, an RO system adjusts the pH level of the water then prefilters it. Profiteering is necessary because the water can have particulates that can clog the membrane. To prefilter the water, it’s passed through a material that can be sand, charcoal or a deionizer. Then, the water is pumped through the RO membrane and cleansed of contaminants, which are drained away as the clean water is stored in an accumulator tank.

It is true that RO systems used to waste a great deal of water when they worked, but the technology has advanced to the point where they waste less and less water. Another problem was that the contaminants could build up over time in the membrane module, but this can also be corrected by changing the main filter on the unit. The membrane is encapsulated with the other ones so it is changed out each time giving you a higher quality of water.

PH levels can be incresed by adding an additional filter this will make the water around an 8 on the PH chart.
