Buy a portable water filter
I think a lot of people know what a filter can or cannot do. It is a water treatment device that every home should have so they don't have to spend money on bottled water. Water filters or purifiers will ensure safe, healthy, and refreshing water at home or away from home.
Water filtration occurs when it is passed through a porous medium (a filter cartridge) to remove suspended matters or particles. Particles to be removed in your drinking water may include sediments, silt, and microorganisms including bacteria, and viruses. Sediment cartridge filters are great for removing dust, rust, dirt and other suspended particles in your water. Carbon filters are used to remove unpleasant taste and odor in water.
Reverse Osmosis (RO) systems use a membrane technology that will allow contaminated water to pass through while retaining the contaminants. While RO systems can take out all sediments and they will also remove minerals
from the water; RO tends to use a lot of water.
Whichever filter types you decided to buy, they may become clogged over time and a replacement filter will be needed. This also is an essential part of using water filters. Filters will retain the contaminants they have removed. So, by not changing your filters as recommended by the manufacture can result in your filtered water becoming contaminated than the raw water.
What happen if the filter pores are filled to capacity and is now holding pathogenic bacteria and viruses it has removed from the water supply? Most of the microorganisms on the RO surface will eventually flush into your
drinking water. Imagine an ocean of bacteria entering your water system in a great flood and you get the picture.
To protect you from this ever happening to your drinking water, you install a disinfection system to complete your water filtration mechanisms. This will ensure that all water passing into your drinking water system is absolutely safe to use and free of bacterial and viral pathogens.
But the most important precaution is to buy a replacement cartridge water filter to ensure consistent refreshing and healthy water that is free of potential re-contamination.
Why should you be spending money on bottled water? Check out different online retailers for the best water filter that will meet your need. In fact, buying a water filter will not only save you money, it will help the environment. Plastic bottles takes a long time to decay. Do a quick web search for affordable portable water filter if you desire to carry water to work, school, camps, or if you are traveling to foreign countries.

How Water Filters Work
Ah, that wonderful refreshing taste of a tall cold glass of water. Cooling, soothing and pure. But is it pure? What about all those invisible microbes and bacteria? What about all those pesticides and herbicides you don’t see? It’s enough to spoil that thirst-quenching moment.
So how do you get pure drinking water? Most people get a water filtration system. However, no one unit can remove all the impurities in our drinking water. And there are many types to choose from. If you have a better understanding of how water filters work, then you’ll be able to get the right one to fit your lifestyle.
Water filters were invented for good taste – and safety
Water filtration systems have been sought since as early as 4000 B.C. to clear the visible cloudiness in drinking water. We humans have a penchant for purity, don’t we? Especially for something we’re putting inside our bodies! That desire for purity has grown in the last few decades, and has been joined by a desire, also, for safety.
We not only want the water that we drink to be pure, with good taste and odor, we also want to know that we have safe drinking water; that is, free of impurities like bacteria, poisonous chemicals and minerals. And as science discovers more of these in our water, we need to find systems that’ll filter them out. These impurities can be very harmful, causing diseases and malfunctions in our bodies. And since health is such an emphatic issue these days, we need to be making wise decisions about what we eat and drink.
These were the thoughts of Heinz Hankammer and his family as they produced a water filter that would provide, in a simple format, clear water – free from impurities. Heinz named his company after his daughter, Brita, which you’ll probably recognize as the leading manufacturer of freestanding household water filters today. Brita led the way in producing the simplest and most cost-effective way of improving water quality.
Water purification and filtration can be quite technical
We’re going to give you here, a simple explanation of how water filters work. We’ll look at the different types available, while trying to stay away from the technical terms so you’ll get a clear understanding. Remember, if you understand something, you’re far more likely to remember it.
Most filters today are charcoal, or activated charcoal. Charcoal, which is mostly carbon, is the residue of partial burning or destructive distillation of organic material. When special heating or chemical processing is added to charcoal, it becomes much more absorptive, and is then referred to as “activated charcoal”. So a charcoal filter works on the principle of absorption. Large volumes of gases, including most poisonous ones, stick to the charcoal, which is quite porous. (That’s why it’s used in gas masks.) Because it has such a large porous surface area, it absorbs a lot of impurities. Charcoal filters are used in icemaker filters, under-counter filters, countertop filters, whole-house filters, and more. You get the message – charcoal really “takes out the garbage”.
Another type of water filtration system available today is reverse osmosis. That’s the technical name for the process of water being pushed through an ultra-fine semi-permeable membrane, where it separates the tap liquid into the pure permeate which is diverted to a storage tank for later use; the brine concentrate is diverted down the drain. The water is stored in a pressure tank and is treated to a final activated-charcoal polishing filtration stage to remove all remaining odors and tastes before dispensing the purified water into your glass. The disadvantage of reverse osmosis systems is that they waste a lot of water – for every gallon of purified water produced, two gallons are wasted.
Other types of water filters are ion exchange and distillation. Ion exchange is designed to remove dissolved salts in the water, such as calcium. This system actually softens the water or exchanges natural-forming mineral ions in the water with its own ions, thereby neutralizing their harmful effect of creating scale build-up. The ion exchange system was originally used in boilers and other industrial situations before becoming popular in home purifying units, which combine the system with carbon.
Distillation is the simple process of boiling water to create steam. The steam cools and condenses to form pure mineral-free water droplets which are deposited in a container. When combined with carbon, the result is 99.9% pure contaminate-free water. These systems are extremely efficient and reliable, and are regarded today as one of the most effective ways to remove contaminates from any water, from any source.
One other water filter worth mentioning is the portable variety. If you do a lot of camping or hiking, these are the wise choice for you.
A summary of filtration systems and what they do and don’t do:
Activated Carbon Filters – Do: absorb organic contaminants that cause bad taste and odor; some models remove chlorination byproducts; some models remove cleaning solvents and pesticides. Don’t: remove metals such as lead and copper; remove nitrate, bacteria or dissolved minerals.
Ion Exchange Units – Do: remove minerals, particularly calcium and magnesium that make water “hard”; remove fluorides; some models remove radium and barium. Don’t: soften water if it has oxidized iron or iron bacteria, which clogs the system when the ion-exchange resin becomes coated.
Reverse Osmosis Units – Do: remove nitrates, sodium, other dissolved inorganic and organic compounds; remove foul tastes, smells or colors; possibly reduce the level of some pesticides, dioxins and chloroform and petrochemicals. Don’t: remove all inorganic and organic contaminants.
Distillation Units – Do: remove nitrates, bacteria, sodium, hardness, dissolved solids, most organic compounds, heavy metals, and radionuclides; kill bacteria. Don’t: remove some volatile organ contaminants, certain pesticides and volatile solvents; stop bacteria from recolonizing on the cooling coils during inactive periods.

Water purification
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: ultra violet light, filtration, water softening, reverse osmosis, ultrafiltration, molecular stripping, deionization, and carbon treatment.
Water purification may remove: particulate sand; suspended particles of organic materal; 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 sulphide 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 potable drinking water. Quality standards in many countries require specific amounts of disinfectant (such as chlorine) in the water after it leaves the WTP (Water Treatment Plant), 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 charcoal 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. Lab 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".
