Water is the primary ingredient of life – not only on this planet but also in the universe; wherever life exists. Water is so essential for creatures living on Earth that three-quarter area of this planet is covered with it, and only one-fourth area has walkable land. That’s not all, 50 – 70 percent of a human body is water; most of it lies in human cells. Therefore, it is important to drink contamination-free pure water. A dominant majority of people are living their lives on impure water. Water purification, thus, becomes a necessity. In spite of the fact we may have the advantage of access to genuinely clean water, there are still synthetic compounds and contaminants in our water supply. As indicated by a United Nations’ report, unclean water is a certain indicator of shortened life expectancy. The significance of clean water; therefore, can’t be exaggerated. There are several methods to clean it. We shall describe the most popular water purification methods today in 2018. Water Purification Mehods | Happylife Read    

1.     Boiling

The most widely used water purification method is boiling. In many homes in Pakistan, boiling is the most generally adopted technique to purify water. It’s based on the belief – which is not fazed though – Water that will be bubbled ought to be very clean and safe. It is simpler with a kettle. All needed to be done is pour water in it’ turned on the fire, then wait. Your clean water is ready once bubbles begin to appear. Once bubbling, you should proceed for around 2 to 3 more minutes before turning off the stove. Pros:

water boiling
  • Kills nearly every living thing
  • Vaporizes many chemical substances.

Cons:

  • Metals turn out to be more concentrated.
  • Metals turn out to be more concentrated.

2. Slow Sand Filter

Also called as biosand or biological sand filter. A slow sand filter consists of a bed of graded sand which is bolstered by a layer of gravel. This filter media is bound in a container with openings at the two closures enabling water to stream in and out while working on a top-down, gravity premise.

Pros:

  • Solids and water muddiness is normally separated.

Cons

  • Some microscopic organisms still remain.

3. Fiber Filter

These fibers contain cellulose, rayon or some other material spun into a work with little pores. It is much the same as pouring water containing sand through a bit of fabric. Dissimilar to slow sand filter, weight is connected to compel water through firmly wrapped fibers. There are numerous sorts of fiber filters in the market in a variety of shapes and sizes from fine to coarse meshes. Go for fiber fibers with micron evaluations lower then 1 to effectively trap particles.

Pros:

  • Sediment and sloppiness are evacuated.
  • Small natural particles that cause awful scents and taste may likewise be expelled.

Cons

  • Anything that is dissolved in water like chlorine, lead, and mercury isn’t evacuated.

4. Activated Carbon/Charcoal Filter

Charcoal is carbon. Activated charcoal will be charcoal that has been treated with oxygen to open up a large number of minor pores between the carbon iotas. The utilization of exceptional assembling systems results in exceedingly permeable charcoals that have surface zones of 300-2,000 square meters/gram. These activated charcoals are then used to adsorb substances from fluids. Activated charcoal with a genuinely wide surface region has the innumerable potential for bonding chemicals to the surface. Activated charcoal is great at catching other carbon-based impurities, and additionally, things like chlorine. Numerous different synthetics like sodium and nitrate are not pulled in to carbon at all so they go directly through. This implies an activated charcoal channel will expel certain contaminations while overlooking others. It likewise implies that, once the majority of the holding destinations are filled, an activated charcoal channel quits working. By then you should replace the filter.

Pros:

  • Reduces particles chlorine, and makes the taste and smell of water better.
  • Water flow is appropriate for use as all house filter.
  • Typical filter cartridge changes are done yearly.
  • Zero power is utilized.
  • Water isn’t wasted at all.
  • Beneficial minerals, for example, calcium, magnesium, and potassium that are dissolved in the water remains in the water.

Cons

  • Water can flow around the granules without being dealt with as water flows where there is less resistance.
  • Water can cut a filter where it might flow openly with little obstruction, maintaining a distance from contact with the filtration medium.
  • Pockets of contaminants can conform to the granules that will result in a crumple, which taints the sifted flow of water, as the pressure changes.
  • General pitcher filters containing dynamic carbon granules have genuinely large pore sizes of more than 20 microns.

5. Reverse Osmosis (RO)

Reverse osmosis (RO) is the king of the water purification methods adopted today.  is a partition procedure that utilizations pressure to drive water through a layer with extremely small microscopic holes that hold contaminants on one side and enables unadulterated fluid to go to the opposite side. Refined water is gathered from the ‘clean’ side of the layer, and water containing the concentrated contaminants is flushed from the contaminated side.

The healthy happylife™ purifies water with the RO technology!

Pros:

  • Salt and inorganic matter are extraordinarily diminished. In the event that a carbon a filter is utilized for post filtering, the quality will nearly be on a par with refined water.
  • Parasites and infections are totally evacuated in distillation…
  • More treated water is delivered contrasted with refining.

Cons

  • The speed of water produced may not be sufficient for different uses other than drinking, like cooking, washing, cleaning, and so forth.
  • About 3 drops of water is squandered for each 1 drop of separated water delivered.
  • Organic synthetic substances may at present wait Reverse Osmosis treated water.
  • The membrane’s proficiency ends up unpredictable to factors like synthetic properties of the contaminants contaminant concentration, water acidity levels, membrane type and quality, water pressure, and its temperature.
  • In circumstances where high water pressure is absent to force water through the membrane, it doesn’t work.
  • The pre and post fibers that accompany most Reverse osmosis frameworks require changing occasionally as indicated by producer’s proposal.
  • The stockpiling tank requires standard cleaning to guarantee the high caliber of water put away.
  • Damaged membranes are difficult to notice, for this reason, it is difficult to discern whether the system is as yet working properly.

6. Distillation

Refined water is pure & unadulterated water that is acquired in a procedure that catches the unadulterated steam from boiling water. The water turns to fluid form again through condensation’. A vapor trap, carbon filter, or other devices ought to be utilized alongside a distiller to guarantee a more removal of contaminants.

Pros

  • Very clean & pure water is caught.
  • Removes minerals, salt, chloride metals, and others that carbon neglects to dispose of.
  • Bacteria, protozoans, and infections are killed or abandoned when water evaporates.
  • The final a product will dependably be high-quality treated water regardless of nature of the entering water,
  • Unlike fibers, there is nothing to supplant.

Cons

  • Long hours are required to accomplish a significant amount of water. For instance, it might take 30 minutes or longer to get 1 glass’ worth (of refined water.
  • Water can’t be distilled without electricity, making it totally unattainable if a crisis emerges.

7. Chlorine Bleach

Chlorination is the method of adding chlorine to water for water refinement as a technique to make it fit for human utilization as drinking water. Water which has been treated with chlorine is compelling in preventing the spread of waterborne illness.

Pros:

  • Cheap.
  • Commonly accessible in drug stores, grocery store, and advantageous stores.
  • Effective against microscopic organisms and infections.

Cons

  • In the water, Initial chemical contamination isn’t affected.
  • Increases cholesterol developments.
  • Carcinogenic in large sums.
  • May cause heart illnesses in light of the fact that in the blood, chlorine reacts with calcium which makes it end up toxic and non-soluble. At that point, it moves toward becoming plaque

8. Iodine

This is a common chemical purification method mostly utilized by campers. With the best possible iodine concentration and a 30-minute contact time in modestly turbid water that is kept up at 20C/70F or higher, every single harmful bacterium and most infections are crushed.

Pros:

•       Effectively kills microorganisms such as bacteria, viruses, and other protozoans. •       Lightweight and helpful.

Cons

•       Does not affect the cryptosporidium protozoa that can cause gastrointestinal ailment with loose bowels (diarrhea). •       The more the time is required for appropriate cleansing as the water gets colder. •       Does not change the clearness of water but rather changes the taste. •       Iodine is best to use for short-term utilization…

9. Ozone/O3

O3 is a shaky and unstable molecule which promptly surrenders one atom of oxygen giving an intense oxidizing specialist which is toxic to most waterborne protozoans and organisms. Ozone is made by passing oxygen through bright light or a cold electrical discharge. To utilize ozone as a disinfectant, it must be made nearby and added to the water by bubble contact.

Pros:`

•       Inactivates unsafe protozoa that frame cysts. •       Effective against most viruses, microbes, and microorganism. •       Produces less unsafe results than chlorine.

Cons

•       No disinfectant residual is left in the water.

10. Ultraviolet/UV

Water goes through a clear chamber where it is presented to Ultraviolet light. UV light effectively annihilates microbes and infections. Notwithstanding, how well the UV system works relies upon the energy dosage that the living being ingests. On the off chance that the vitality dosage isn’t sufficiently high, the living being’s genetic material may just be harmed as opposed to disturbed.

Pros:

  • Very effective at inactivating cysts.
  • No dangerous side-effects.
  • No added smell and taste to treated water.
  • In reality, the taste will enhance as natural contaminants are devastated.
  • Requires almost no contact time.
  • Many sorts of microbes, viruses, bacteria, and microorganism are wiped off.

Cons

  • UV light’s disinfection effectiveness diminishes as the water gets muddier. Suspended solids cause that consequence of the scattering, retention, and shadowing.
  • Just like ozone, no leftover disinfectant is left in the water, inciting a need to include a remaining disinfectant.
  • Anything that isn’t ‘alive’, like lead, asbestos, and chlorine, are not influenced by Ultraviolet light.
  • Will not work without the nearness of power.

11. Solar Water Distiller

A clear plastic obstruction like a plastic grocery ground fabric, or a plastic bag, is set over the water source. The sun goes through the boundary and warms the source which at that point vaporizes, rises and afterward condenses on the underside of the plastic obstruction. The moisture gathered is drinking water.

Pros:

  • Capable of refining any spoiled water including seawater.
  • Drinkable water can be consolidated from anything that has dampness.
  • Easy to have and has a low effect on the earth. All that is required is a container to get water and an expansive sheet of clear plastic.

Cons

  • Source materials that emit poisons like radiator liquids or fills are not distillable.
  • The refining process is to a great degree moderate and just a small amount can be gathered day by day.
  • Wild salmonella replicates immediately when stored in the dark, requiring 10 parts for each million of hydrogen peroxide (HO) to solve the issue.
