Reverse osmosis filtration removes most ions and large molecules from the water with the application of pressure when it is on one side of a membrane. A membrane is a layer of material that acts as a barrier between two stages that filters specific substances, particles and molecules. The filtration system is used in purifying drinking water, landscape irrigation, industrial cooling, in concentrating food liquids, car washes, maple syrup production, hydrogen production, in artificial mixture of seawater in reef aquariums, and in the desalination process.

Reverse osmosis installation requires that a homeowner does research first. The internet is a rich source of information on this system. The system has two types of membranes: thin film composite and cellulose triacetate. Thin film composite is a better membrane than cellulose triacetate. However, if the water is rich in chlorine, a homeowner must buy a carbon pre-filter to get rid of the chlorine because thin film composite is sensitive to chlorine.

After choosing the membrane, a homeowner must then choose a reverse osmosis installation system configuration. The standard configuration is a filtration system that is under the sink with the faucet functioning as the water dispenser. For 100% pure water, a house owner can purchase an additional deionizing filter to get rid of the last bit of impurities.

The next step is to search for the reverse osmosis filtration system. Buying online can be the best and cheapest alternative for reverse osmosis filter systems. With regular maintenance, a filtration system bought online for $200 can last a lifetime. There are companies that sell known brands and there are individuals who manufacture the said filtration system.

A system bought from an individual can help answer a homeowner’s questions personally. The seller can find all the quality parts in building the filter system and will not push a particular brand. The seller can also sell replacement filters at a discount. Also, a filter system made by an individual can be bought at a cheaper price than the known brands although known brands can give more peace of mind to the house owner. In buying from an individual, one must make sure that the seller has been in business of manufacturing reverse osmosis filter systems for a long time.

A drill and some basic plumbing experience are needed in reverse osmosis installation. The system must be installed near the water source and sink. The output tube of the filter system must be connected to the sink waste pipe. The source water tube must then be connected to the cold water pipe. A shutoff valve must also be installed in the connection.

When everything has been set up, fill the filter tank with water to about halfway full to check for leaks. Fix the leaks and try again. Flush out the first two tanks of filtered water to get rid of any impurities in the tank and filters.

The osmosis process was first observed by Jean Antoine Nollet in 1748. Up until 1948, the osmosis process was only an observed phenomenon in the laboratory with no real use in communities.
