A home water purification system is more essential in todayís modern home now more than ever. The earliest reliable municipal public water systems were installed some fifty years ago. These system are old, delapitated and although many cities have made efforts to replace public water systems they are not without their own difficulties. Public piping systems have been known to break most especially due to natural disasters. Disasters such as freak weather storms, earthquakes and tsunamis among others can leave the public systems open to contaminating materials and debris. When these contaminants enter the public water system, they will eventually make their way to you home unless they are somehow filtered out.
When events such as natural disasters occur, there is little majority can do about broken municipal water pipes. We can however do something about the water quality in our own homes. A home water purification system allows you to do just that. By filtering incoming municipal water before allowing it to flow through your household water piping network, you can ensure you receive safe water. But what hazards do these systems help you avoid? The hazards that can contaminate a public water supply can take two forms - either inorganic or organic compounds. Organic compounds have carbon (and at times hydrogen) based molecules. The most commonly found contaminants in tainted water include hydrocarbons such as petroleum and oils, certain forms of insecticides, fertilizers, phosphates, heavy metals (such as lead and Iron), nitrates, protozoan bacteria and viruses (such as Giardia, hepatitis, cholera, Cryptosporidium and Schistosomiasis). To purify the water supply, the home water purification system must be able to remove the pollutants mentioned. They do this by using a semi permeable membrane that has pores of a certain diameter. Filtrates have molecules with diameters larger than water molecules and are unable to pass through the membrane.
Not every home water purification system has the same membrane pore size. In fact, different manufacturers employ one of two common technologies that by design have different pore sizes. For instance, a home water purification system using a carbon based membrane is limited in what it can filter due to the large diameter of itís pores. Pore sizes on membranes in reverse osmosis filtration systems are typically much in diameter measuring as low as 0.00015 microns. Essentially this means that depending on the technology, only specific contaminants can be filtered. For example carbon based purification systems work well with debris and certain chemicals but work poorly against bacteria whose bonds are in the one thousandth range in diameter. Reverse osmosis purification systems have no such limitation and are effective against a broad spectrum of contaminants.
The step towards purchasing and installing a home water purification system should always begin with knowing what you are up against. Starting by eliminating your home as the cause of the contaminated water in your house by having your plumbing thoroughly checked.
