Then when the raindrops land on something and eventually evaporate, they leave behind a layer of dust.”

Why is rainwater not pure?

Rain water is considered the purest form of water. Impurities and salts present in water on earth are left behind during vaporisation by the sun. However, the rain water we receive on earth is not necessarily pure, as it brings down impurities and particles present in the atmosphere along with it.

Does rain water have dirt in it?

Rain has to be dirty. Water droplets in clouds form when water vapour changes into liquid water around a condensation nucleus, such as a tiny particle of dust or soot, or a flake of salt. These coalesce to create clouds and ultimately fall as rain.

How do you purify rainwater?

To remove the smell and the taste of chlorine in the drinking water, you can use an activated carbon filter or charcoal filter. This system is made of coconut shells, carbon, and other eco-friendly solution. The last method of filtering rainwater is through solar pasteurization.

How do you filter rainwater?

Should you boil rain water?

Boiling the water kills just about any bacteria or pathogens that are in the water. You can use this method when wanting to use rainwater for things such as watering plants, bathing, etc., however, it is strongly recommended that one does not try to boil water as a means of purifying it for drinking purposes.
