How to Make a Water Purifier

by Jane Smith2016Introduction:The importance of clean water can't be stressed enough. Yet, in order to have pure water you have to purify it first.

The easiest way is making a home water purifier that will cost you next to nothing and is easy to assemble. Let's see how (1).

Potential Health Issue: Pollution in the Groundwater or Surface Water Resources: According to the World Health Organization (WHO), over 2 billion people lack access to safe drinking water and more than 4 out of 10 people lack access to basic sanitation facilities.

Groundwater is becoming the main source of drinking water supply. In the US, groundwater provides drinking water to over half of population, while it is a major supply source in Australia, China and India (WHO, 2014).

Purifier:It works on solar power and works as a distiller. It uses the sun's energy to purify water by boiling it. The set up is very easy; add

water in the pot and place an empty glass container (for distilled water) on top of the pot. Let it out in lunch time when sunlight isn't strong direct. That is why it's called Solar Water Distiller.

After 3-4 hours you can collect distilled purified water from top container . You can use this distilled water for drinking and cooking.

Purification of the water is done by the distillation process. The steam from boiling water rises up and leaves the harmful chemicals behind. The condensed water that emerges from the top of distiller is clean drinking water (2).

The distiller works using principles of a solar still, which is also a simple way to purify contaminated water (3).Distillation:

Distillation consists of boiling the water and then capturing and condensing the steam in a separate container. The process can be repeated to increase purity until all impurities are gone so that no impurity remains in the final product (4).

Distillation works on the principle of evaporation and condensation. Distillation is the process of boiling water and then capturing the steam and then condensing it back into water. The pure water that emerges from the top is collected in a separate container for drinking.

It can get rid of chemical contaminants, microorganisms and salts (5).Water purification systems can be separated into two types – physical and chemical. Physical systems rely on filtration to remove contaminants (6).

Filters use physical barriers to stop microbes from passing through. Designers have included several filters in succession to trap as many microbes as possible in each step of filtration (7).

Chemical purification systems use chemicals such as chlorine or ozone to remove contaminants (6).On the other hand, distillation is a physical process. It works by boiling water and then capturing and condensing the steam in a separate container. The process can be repeated to increase purity until all impurities are gone so that no impurity remains in the final product (8).

The basic principle of distillation is that liquids boil at different temperatures depending on their composition (9). Distillation can be used to separate compounds based on their differences of boiling points. The distilled components have similar purity to the original compound, which makes it useful for separating compounds with similar boiling points from each other (10).
