Because each water filtration technology removes a certain types of contaminants, none can be relied upon to remove all contaminants. A quality water purification system uses a combination of purification and filtration technologies to achieve the highest water quality. There are quality water filtration/purification systems available that utilize a combination of contaminant removing technologies. Below is a list of common types of water filtration systems that are available as a single system or in combination with other technologies:

Ion Exchange: With ion exchange technology, ions in the water are exchanged for other ions. The most common ion exchange for drinking water systems is a process called deionization. The ion exchange process filters water through bead-type spherical resin materials. Ions in the water are exchanged for other ions that are fixed to the beads. Deionization beads exchange either hydroxyl ions for anions or hydrogen ions for cations. The cation exchange resins exchange a hydrogen ion for such cations as Al+++, Na+, and Ca++. The anion exchange resins will exchange a hydroxyl ion for anions such as Cl-. The hydrogen ion from the cation exchanger will join with the hydroxyl ion of the anion exchanger to create purified drinking water. Deionization systems remove ions, but they do not effectively remove most organics or microorganisms. When used in combination with other methods such as carbon adsorption, Deionization is an effective water purification system.

Carbon Adsorption: Carbon absorption is common method used in home eater filtration. Activated carbon is effective removing odors and improving the taste of the water. It removes chlorine as well as many gases and chemicals. However, it is not effective at removing harness, dissolved solids, and heavy metals. Normally it will not affect total dissolved solids, hardness, or heavy metals. Two types of carbon filter systems are solid block carbon and granular activated carbon. Carbon is normally used in combination with another filtration/purification treatment process.

Reverse Osmosis: Reverse osmosis is an effective and cost-efficient method of removing 90% to 99% of all contaminants. The pore composition of reverse osmosis membranes is much tighter making them capable of eliminating basically all organics, particles, and bacteria. Water bottling companies tend to use reverse osmosis technology. The process of osmosis will take place when two different concentrations in solutions are divided by a semi-permeable membrane. Osmotic pressure forces the water through the membrane and the water dilutes the more concentrated solution. Pure water is forced from the concentrated solution. Reverse osmosis removes a number of impurities from the water such as asbestos, total dissolved solids (TDS), many dissolved organics, chlorinated pesticides, radium, lead and other toxic heavy metals. The process of activated carbon filtration and reverse osmosis are often combined in a water cleansing system to purify tap water.

Ultraviolet (UV) Radiation: This method has been used as a germicidal treatment for water as it is effective at sanitizing water. The adsorption of UV light by the DNA and proteins in the microbial cell results in the inactivation of the microorganism.

To ensure the quality and safety of your drinking water, a quality water filtration system is needed. It will provide you and your family with clean, great tasting, and healthy drinking water.
