At Clear Water of San Marcos we don’t just serve homes when installing water filtration systems, we also service commercial facilities. We understand that keeping clean water in your business is a top priority for both employee and patron health. We have several options when it comes to commercial water filtration systems, but today we will be discussing the benefits of a reverse osmosis water filter.

A reverse osmosis filtration system is great for producing clean drinking water. Reverse osmosis may seem complicated but it is actually a fairly simple process and understanding how it works should eliminate the mystery and confusion many feel toward reverse osmosis systems.

Reverse osmosis is a process in which dissolved inorganic solids are removed from a solution, such as water. This process occurs when water pressure pushes the tap water through a semi permeable membrane. The thin membrane allows only water to pass through and leaves behind any impurities or contaminates. The chart below is borrowed from ESP Water Products and very easily demonstrates this process.

The reverse osmosis water filtration systems have many benefits. They improve taste, odor and appearance or water as well as removing all pollutants. It consumes no extra energy because it relies on natural forces and the normal use of water pressure and flow. It does not collect pollutants but instead flushes them out of the system and down the drain, making it extremely easy to keep clean. It is also fairly easy to create, giving it a low production cost, in turn making it more affordable for anyone to purchase.

The reverse osmosis membrane will remove any and all particles which are larger than .001 microns. This includes the majority of sulfate, mercury, phosphate, lead, arsenic, fluoride, barium, chloride and many others. While it does filter out some non-harmful particles such as calcium, iron and zinc, the benefit of the removal of dangerous substances far outweighs the loss of these which can still be gained from proper diet.

There are a few basic components of al reverse osmosis systems.

A cold water line valve that fits onto the cold water supply line and has a tube that attaches to the inlet side of the reverse osmosis pre filter which send water to the reverse osmosis system.

The pre-filter mentioned above is the first contact the cold water meets. It is mostly a sediment filter used to remove silt, dirt and other sediment. There can be carbon filters which remove chlorine which can damage the filtering membrane.

The reverse osmosis membrane is the most important component of the filtration system. It is most commonly a wound spiral which can be either a cellulose tri-acetate which is chlorine tolerant, or a thin film membrane composite/material which is not chlorine tolerant.

The post filter is usually a carbon filter that filters the remaining substances before it goes to the reverse osmosis faucet. Any remaining tastes and odors are removed with this filter.

The automatic shut off valve is used to conserve water by stopping and further water from entering the membrane once the storage tank is full. Once water from the storage tank drains, the pressure in the tank drops, opening the shut off valve and allowing water to flow as well as letting the system drain the waste-water.

A check valve is located in the outlet end of the reverse osmosis membrane which prevents backflow from the storage tanks which could potentially rupture the membrane.

The flow restrictor regulates the flow by maintaining pressure on the inlet side of the membrane. Without it, very little drinking water would be produced because all incoming water would take the path of least resistance and flow down the drain line.

The storage tank holds water after it has been filtered and a bladder inside the tank keeps water pressurized when the tank is full.

The unit has its own faucet which is usually installed on the kitchen sink and a drain line runs from the outlet end of the reverse osmosis membrane to dispose of the filtered out impurities.

Now that you know more about the reverse osmosis system, we hope your interest is peaked. We have a state of the art system with optional special features, a one-of-a-kind on the market.
