How can we improve water quality in terms of recycling it wif cheap means or add something 2 make it drinkable?
The world is experiencing a scarcity of water.
Africa,especially,does not get enough drinking water because there is lack of water supply and they are too poor to sanitize the water.
Is there any means whereby we can add something to the water or any simple system that can reduce cost of sanitation by sanitizing seawater or rainwater to get drinking water ?
There are a number of people working on the problem of finding ways to make cheap, clean, drinking water available to more people. Depending on what specifically the problem is in your water, the solution is a bit different. As far as something you add, potassium permanganate has traditionally been used to disinfect water (though it can leave it with a pink color). There are some microfilters that have been developed that can take dirty water and render it free of bacteria, etc. Examples would be the LifeStraw or the Life Saver Bottle.
For sea water the big issue is going to be removing the salt, and doing that will require either distillation or some other sort of separation (like reverse osmosis). In most places rainwater is generally clean and drinkable, the issue is just finding a way to capture it.
Evaporation would work in africa… use a parobola.. like a magnifying glass on a shallow sealed container of water.. the heat would evaporate the water.. condense and then drink.
