Water Treatment and Purification Methods

Many people find their water too hard, too cloudy, too odorous, too funny tasting, or they have health concerns for themselves and their children.

Many people today have become concerned about the quality of their drinking water. A growing number of contaminants are regulated by the government's safe drinking water standards. These contaminants enter water supplies through landfills, deteriorating underground storage tanks, industrial waste, agricultural fertilizers and pesticides, sewer discharges reaching other sources of water supply, and leaching from pipes, solder and connector joints.

Individuals contaminate, too. Some believe storm sewers, septic tanks or empty lots are safe dumping grounds for home chemicals such as used car oil and cleaning solvents. Disposed this way, these contaminants can find their way into the water supply. In addition, in both rural and suburban areas, pesticides and fertilizers are posing water quality problems. In some regions, the contamination is widespread.

By the time it flows from your tap, water has already been treated with a variety of chemicals and by a variety of processes to clarify it, alter it and disinfect it. Even though some of the more difficult questions are unresolved, the fact remains that many individuals find their water too hard, too cloudy, odorous, funny tasting, or they have health concerns for themselves, their children, and especially during pregnancy or illness.

Tap water is, thus, properly viewed as raw material for further improvement by the commercial, industrial and domestic user.

Both private-well users, estimated at more than 15 million across North America, and an increasing number of consumers on public water systems have decided to install a final barrier of protection or to simply improve the water in their homes or businesses. It is estimated that more than 30 million homes have point-of-use systems installed, and that number is growing by more than a million a year. Add to this the bottled water industry, and you have an important, publicly acceptable augmentation to central drinking water treatment, or in many cases an alternative to it.

Water quality can be improved at the time the water is to be used, in the appropriate amount and to the desired level. On average, the typical municipal water treatment plant yields 183 gallons per capita per day - but less than 1 gallon per person per day is used for drinking and cooking. The other 182 gallons per capita are used for other purposes, such as sprinkling lawns, flushing toilets, washing laundry, bathing, cleaning streets, fighting fires and industrial uses.

Single problems, such as simple hardness or one contaminant, may be effectively resolved with a single water quality improvement technique.  For several problems, the answer might be found in a combination of equipment. For example, chlorination may be used for disinfection and the precipitation of iron or hydrogen sulfide, which is then removed by filtration. Or activated carbon may be used in combination with reverse osmosis treatment to remove low molecular weight organic compounds that pass through the reverse osmosis membranes.
