Best Techniques for Water Purification

water purification

It is always a good idea to understand several techniques for water purification.

For example, having different ways to purify water can be helpful in cases of emergency during a crisis situation when your water supply is cut off.

Purifying water should be one of your survival priorities because humans can only last just about 3 days without any drinking water.

However, the good thing is that these techniques are not difficult and it produces good result.

This article will highlight some of the best water purification techniques you should know especially in case of an emergency.


This is one of the surest ways to purify water because it kills pathogens, bacteria and parasites present in the water.

However, the drawback is that it may become unrealistic in a situation where there is limited energy.

But beside this, it is one of the best techniques for water purification. % to 10 mins of boiling will kill most organisms.

It is also important to note that the higher the elevation, the, longer you may need to boil the water.

Like it has been said earlier, this is one of the best water purification techniques if there is a heat source.


Water distillation is one of the best water purification techniques especially in a situation where the only available water is dangerous water mostly after a disaster.

For example, heavy metals, radiation, salt and lead can make a mess of your water supply when disaster struck and using the filter option will ruin your water filter.

In this process, water is simply boiled in an enclosed container and the escaping steam is captured and allowed to be converted back to water in a clean container.

It is important to state that this method provides very clean water but it uses a high ton of fuel. Distillation is simply effective even though it is a little complicated in water purification.


This is one of the best water purification techniques, easiest and most effective.

The process involves water running through a medium like silver, charcoal and sand which strains out contaminants.

Two of the most used filters present today are the suction filters and pump action filters and can come in different forms.

Note that filtration can be used in conjunction with other purification methods like chemical and heat.

Ultraviolet Lights:

These deal a very heavy blow to small organisms in the water and very effective water purification technique.

However, it is important to note that UV lights are much more effective when the water is clear.

For example, they might not be very effective for water containing some large floating particles but can be at its best when it has to with clear water with an unknown origin.


You can purify water using those chemicals that are capable of killing parasites, viruses and bacteria as well as other impurities.

However, when using chemicals, it is important to get the right dose for the purification else you may taste it on the water.

Using too small may not get the job done and using too much may cause illness.

Chemicals are easy to use with instructions clearly written on how to make best use of it.

Except in cases it is stated differently, water purified using chemicals is expected to sit for a period of 30 minutes so as to allow time for the chemical to make an impact on the water.

There are many water purification techniques but the choice to use them depends on the filtration needs. However, the techniques listed above are considered to be among the best that can guarantee a good result.
