Best Water Purification Methods Explained |
|
We decided to explain the best water purification methods in order to help people understand how hard is for the world governments to provide clean healthy water for all of us . If nowadays the large part of the urban societies are used to pay for, either mineral water or some other type of water-based drink, the availability of clean, fresh water should be a benefit to every human being
on this Earth being a basic human need!
Tap water is used lesser and lesser for drinking purposes which has partly to do with the fact that some countries introduced excessive levels of Fluoride in water (for ex. in the US, England etc.) to supposedly prevent tooth decay, which in fact has been proven to be toxic and the cause of undesirable cosmetic effects such as staining of teeth (Activated alumina can be used as a good fluoride adsorbent).That is why more and more people decide to install a water purification system in their homes.
Methods for clearing water were known and used by people since ancient times, as for example, distillation,through which 99.9% pure water can be obtained, or boiling, to inactivate or kill micro-organisms.
This easy techniques surely provide to a curtain degree clean and healthy water but some of the bacteria and
other organisms still survive this harsh treatments to finally end up in our bodies. Cryptosporidium , which is a small organism found in man and many other animals is one example. It can cause a disease called cryptosporidiosis, which is a diarrhoeal illness usually lasting about two weeks. Water that has not been suitably filtered can contain numbers of Cryptosporidium oocysts shown to cause illness.
Best Water Purification Methods
Here are the different methods of water filtration one would consider:
1. Distillation – probably the oldest but at the same time the most inefficient method – Removes a great deal of
harmful micro-organisms and pathogens but requires large amounts of energy and water to operate, is expensive and above all, some contaminants still manage to pass into the condensed substance.
One product that uses this method is the .
2. Carbon Absorption – a common method used nowadays because it is capable of removing bad tastes and odors, including chlorine but fails to do its job when it comes to total dissolved solids or heavy metals. There are two types of carbon filter systems: granular activated carbon and solid block carbon. The systems provide a long life functionality. You might find product interesting. Some of it’s features include removal of up to 95% of VOCs, TOCs, chlorine, sediment and filtration down to 1 micron.
3. Ion Exchange – this water purification technology uses sphere-shaped resin materials to cleanse the ions in water. A differentiation between softening and deionization systems is made. In the method of softening, water hardness is being reduces before, normaly, a reverse osmosis processing takes place, whereas deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Deionization systems effectively remove ions, but on the other hand fail to properly remove most organics or microorganisms. They also can stimulate bacterial culture growth and prove to be quite expensive on a long-term usage. Here we present the , which uses the combination of solid block carbon pre-filter
and a high grade mixed bed deionization resin filter for a maximizing water purification efficiency.
4. Microporous Basic Filtration – exists in three different types: depth, screen and surface, but usually all used
into one system. Starting from the most abrasive one, the depth filter, going down to the surface filters which finally removes 99.99%
of remaining solids, the filters integrated in those systems are usually easy to use but are not regenerable and will not filter out chemicals, inorganics or pyrogens.
5. Ultrafiltration – uses a molecular sieve membrane to purify water. It is regenerable, has the highest water quality/ energy consumption ratio but will not
remove dissolved inorganic materials. The is such a product. The filter has a life of 3 years and removes particles larger then .01 microns.
6. Reverse Osmosis – the most cheap method to be yet discovered – is efficient at removing 90% to 99% of all contamination and most leading water bottling plants use
this technology with success. One of the disadvantages is its slow flow rate, that is why large containers are recommended to compensate it. Reverse osmosis is highly effective in eliminating asbestos, lead, turbidity and other toxic heavy metals, such as radium, and so being very efficient in purifying tap water. A decent product can be obtained .
Most of the time this technologies will not be used individually in a water purification system but rather in combination. So, for example reverse osmosis works best with activated carbon filtration, being complementary processes and combining them will result in the most effective treatment against impurities in water. A good drinking water purifier has a price between $400-500. While bottled water may be an improvement over chlorine-fluorided tap water, any well-balanced and effective system would be preferable over bottled water, which is clearly unreliable and expensive.

I’m was wondering when you was going to add me on to your blog roll, your’s is already on mine and ready to view at . thanks
I like my PUR filter! Makes it clearer and takes away the nasty taste of the local water.

In this present environment water purification systems are a must to avoid ourselves for any sort of bacterial infections
Hey that’s an excellent explanation of water filtration, one of the best I’ve seen! One thing though, reverse osmosis removes the good minerals from drinking water, those which are needed for good health especially very young children.
What an excellent article, such a clear explanation of filtering water, well done!
Mixed Bed Resin
When the pure water coming out of your DI bottle isn’t as pure as it was or should be and it’s time to replace the mixed bed resin, don’t throw away the resin that’s in the bottle.
If your water was originally going into the DI bottle at say 84 ppm (parts per million) and was coming out at 0 – 2 ppm but is now coming out at over 11 ppm then it’s unlikely that your pure water cleaning system is leaving the windows you’ve cleaned, spot free.
By obtaining and using a new DI bottle and new mixed bed resin, you can continue to use your first DI bottle with the used resin still in it, as a pre-filter for your second DI bottle.
This means that with two DI bottles instead of one, the water that is still coming out of the first DI bottle with a reading of 11 ppm, is what is going into your second DI bottle with the new and unused mixed bed resin.
This second bottle is now only having to clean incoming water with impurities of 11 ppm instead of with the original 84 ppm.
This will result in your mixed bed resin in the second bottle lasting a whole lot longer than your original bottle lasted.
The savings in having to replace your mixed bed resin less often, will more than cover the cost of buying your second DI bottle.
When the water you’re using starts to come out of the second DI bottle at around 11 ppm again, simply use that as your first bottle and replace the well spent mixed bed resin in your original bottle with new resin and use this DI bottle as your second filter.
This system will ensure that the bottle that your pure water is coming out of, always has water going into it at only around 11 ppm instead of 84 ppm.
