Four steps to help you select the best water treatment solution for your situation. My recommendation for a high-quality Point of Use water purification system This is completely off topic, but if you enjoy good music, I invite you to listen. First you need to understand which contaminants are in your water.
If you are on municipal public water, most water companies are required to provide an annual water quality report. RO requires water pressure, is fairly slow and typically wastes more water than it treats - Solid Block Activated Carbon SBAC is the least expensive process and does not require electricity or high water pressure.
It significantly reduces chlorine, a wide variety of organic contaminants like disinfection byproducts and can be designed to reduce levels of some inorganic chemicals like lead and arsenic.
Activated Carbon is ineffective against many inorganic contaminants like salts, iron, fluoride, aluminum, calcium, etc. Read this to understand what taste salty, metallic or bitter and odor fishy or sewage clues indicate that activated carbon filtration might not be effective.
There are no federal regulations regarding the effectiveness or design of water treatment products. The FTC has created " truth in advertising " rules, but they apparently are not enforced except in extreme circumstances.
Companies are pretty much free to make unsupported claims to promote their products.
Careful selection of water treatment products certified by NSF or WQA provides assurance that water treatment claims are valid. The importance of independent certification for product evaluation There are many thousands products on the market that claim to provide you with the purest, healthiest water available, everything from filtration systems and distillation units to bottled water to water that is claimed to be specially treated to treat various health problems.
There are, for example, over 2, different water filters on the market. An improperly maintained water filter can actually incubate trapped bacteria and release them into the "filtered" water.
I personally believe that a product's performance as well as the accuracy of its advertising literature should be tested and certified by an independent and disinterested third party.
If a product is certified by a reputable company you can be assured that a product's ads are not misleading and the product will perform as specified.
The WQA tests prototype water treatment equipment, and awards the Gold Seal only to those systems that have met or exceeded industry standards for contaminant reduction performance, structural integrity, and materials safety. NSF International is a group that certifies water treatment systems, distillation units, bottled water, water softeners, and a number of other food preparation systems.
NSF certification means that not only do the products perform as tested, the product advertisements are also evaluated for accuracy and truthfulness.
You need to be aware that there are a number of different NSF standards and different levels of compliance within the standards. The latter filter will remove a far wider range of contaminants -- and will also probably cost 10 times as much as the former.
You will also find, if you research water purification devices or bottled water, that many companies state on their literature "Tested to NSF standards". Who backs up that claim? Unfortunately, there are even a few pitfalls to interpreting the certification reports - one of the things to be aware of is what I call " padding the list ".
Check out the NSF site below, and use them as one of your guides to selecting a reliable product. The site has on-line comparisons of many of the products they certify. For over 50 years NSF has been committed to public health safety and protection of the environment by developing standards, by providing education and by providing third-party conformity assessment services while representing the interest of all stakeholders.
You can review certified Drinking Water Treatment Units. To use the guide, for water treatment units, either enter a company name you are interested in investigating or scroll to the bottom of the page and select either the product type counter top filter, under counter filter, etc.
You can look up certified bottled water products by brand name, product type, etc. Two important terms related to water treatment: There is some confusion about the meaning of water purification and water disinfection. Water Purification - "The act of cleaning by getting rid of impurities.Types of Water Treatment Systems The following are various types of water quality improvement systems, which may or may not apply to your particular water problems.
Discuss the options available to you with your water quality improvement professional. Education and information about drinking water treatment and sanitation for backcountry use, including information on removing protozoa such as Cryptosporidium, Giardia intestinalis, and Giardia lamblia; bacteria such as Campylobacter, Salmonella, Shigella, and E.
coli; and viruses such as enterovirus, hepatitis A, norovirus, and rotavirus. " For water treatment, this term refers to the process of removing specified contaminants from a water source. All effective water treatment methods will provide some amount of purification, however, only some methods will disinfect the water.
When water and flocs undergo the treatment process, they go into sedimentation basins. Here, water moves slowly, making the heavy floc particles settle to the bottom.
Floc that accumulates on the bottom is known as sludge.
