Water purification is the process of removing contaminants from a raw water source. The goal is to produce water for a specific purpose with a treatment profile designed to limit the inclusion of specific materials; most water is purified for human consumption (drinking water). Water purification may also be designed for a variety of other purposes, including to meet the requirements of medical, pharmacology, chemical and industrial applications. Methods include, but are not limited to: ultraviolet light, filtration, water softening, reverse osmosis, ultrafiltration, molecular stripping, deionization, and carbon treatment.
Water purification may remove: particulate sand; suspended particles of organic material; parasites, Giardia; Cryptosporidium; bacteria; algae; virus; fungi; etc. Minerals calcium, silica, magnesium, etc. and toxic metals (lead, copper, chromium etc). Some purification may be elective in the purification process, including smell (hydrogen sulfide remediation), taste (mineral extraction), and appearance (iron incapsulation).
Governments usually dictate the standards for drinking water quality. These standards will require minimum / maximum set points of contaminants and the inclusion of control elements that produce drinking water. Quality standards in many countries require specific amounts of disinfectant (such as chlorine or ozone) in the water after it leaves the water treatment plant (WTP), to reduce the risk of re-contamination while the water is in the distribution system.
Ground water (usually supplied as well water) is typically a more economical choice than surface water (from rivers, lakes and streams) as a source for drinking, as it is inherently pre-filtered by the aquifer from which it is extracted. Over large areas of the world, aquifers are recharged as part of the hydrologic cycle. In more arid regions, water from an aquifer will have a limited output and can take thousands of years to recharge. Surface water is locally more abundant where subsurface formations do not function as aquifers; however, ground water is far more abundant than the more-visible surface water. Surface water is a typical raw water source used to make drinking water where it is abundant and where ground water is unavailable or of poor quality. However, it is much more exposed to human activity and its byproducts. As a water source it is carefully monitored for the presence of a variety of contaminants by the WTP operators.
It is not possible to tell whether water is safe to drink just by looking at it. Simple procedures such as boiling or the use of a household activated carbon filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source. Even natural spring water - considered safe for all practical purposes in the 1800s - must now be tested before determining what kind of treatment, if any, is needed. Chemical analysis, while expensive, is the only way to obtain the information necessary for deciding on method of purification.

Chlorine gas makes a "pretty good tasting water"
Chlorine in drinking water is used as disinfectant to kill or inactivate pathogenic organisms. It is known to be very effective against bacteria, viruses, and protozoa, cysts, and spores. Chlorine disinfection has been a major part of water treatment process for a long time. In water treatment process - unless water filters are needed - disinfection is usually the last process to ensure that the remaining bacteria that escape sedimentation process are destroyed. There are different forms of chlorine disinfection such as chloramines, chlorine dioxide, and chlorine gas.
Chlorine gas has been used successfully as the primary source of disinfectant in small water treatment plants because it's less costly than other forms of disinfection. Chlorine gas is also simple to operate and it's more stable. Chlorine gas can be generated onsite, or it can be shipped to the treatment plant. According to one estimate, more than 90% of drinking water treatment plants in the United States are using chlorine gas as a primary form of disinfection.
It is therefore no wonder that in 2007 the Village of Montpelier in Ohio won the gold medal for the world's Best Municipal Drinking Water. According to www.pollutionequipment.com, the award was given by the annual international water Tasting Event in Berkeley Springs, W.V. According to the report the village won in 2003 and 2006.
Mr. Bill Blakely, the water treatment plant's superintendent, declared the water as "pretty good tasting water." This is as result of the changes that were made to the water treatment plant that was built in 1939. Pollution Equipment concluded that "it is evident that gas chlorine is the Village of Montpelier's choice disinfection product" that resulted in their "good tasting water".

Why should you test your water?
Whether or not you test your water will depend on your family health needs, the environment where your water supply is located, age of your house plumbing system, taste and odor of your drinking water, or if you are simply considering a home water treatment system.
A test of your drinking water could do the following for you:
Gives you the understanding of its quality.
Confirms whether or not your drinking water is free of pathogenic, bacteria, lead, arsenic, iron, and other harmful chemicals.
Gives your water a clean bill of health or a direction to do something.
Saves you money because it will help you spend your money on the right water filter or softener. Perhaps you don't need one; you will not be buying one because your neighbor has one.
The environment where your water supply is located can influence the need to test water. Public water suppliers in the United States are required to send an annual Consumer Confidence Report. This report will show information on the test results the water supplier has performed, the concentration level of each chemical detected, health effects of these contaminants, and the sources of water. Majority of water suppliers will not deceive their customers, but recent news events about water treatment plant operators who manipulated test results offer no confidence in some consumers. In this case, and for well water owners, a test will determine whether or not harmful contaminants are present in your drinking water.
The age of a house plumbing fixtures can also determine the need to test water for contaminants. Lead in old house plumbing can leach into the drinking water. According to the medical experts, a brief or prolonged body exposure to lead can cause serous health issues. Test result will help determine the treatment options.
For well water owners, proximity to agricultural environments can influence the need to test what's in the drinking water. Runoffs from animal feeding operations can leak into the groundwater thus contaminating well water supply. Some of the contaminants that can get into well water are heavy metals, nitrates, pesticides, and sulfates. Untreated wastewater that discharges to water supply source and failed septic systems can result in well water contamination. Treatment options for well water contaminations could be the use of a filter system. Testing will reveal what's in the water and what type of water treatment is needed.
Some water analyses can be done in your home by eyeballing such as odor, taste, color, and turbidity. Collecting water for testing for some chemicals requires higher level sampling and testing protocols while others can only analyzed by a state certified laboratory. In some cases, water testing must be conducted immediately while others will need special preservatives before delivering it to the laboratory. In the previous case, the laboratory may send its own technicians to collect the samples. The cost of testing will vary from one laboratory to another. Some laboratory may provide you with sample bottles and directions on how to collect water.
You may contact your state's drinking water authority for guidance on how and where to test your water. However, for information the conditions of your drinking water you may contact your county or town drinking water authority.
Treatment options to remove these contaminants could be a water filter or a water softener. Water filter or softener comparisons of different brands and manufacturers will show the type of treatments each system can remove.Welcome to Waterhoh Water Filtration.Inc，Our products include:drinking water filters,reverse osmosis system,undersink and countertop water Filters, shower water Filters,whole house filters systems, replacement filters cartridges. thank you for looking at our Website......
