how do you purify water without solar energy in emergency?
i mean that you have to have it really fast, because you are in an emergency and all that. you can’t go around trying to find a boiler or chemicals. is that possible?

I’m not sure if this counts as solar energy to you, but you can put the water in a clear plastic bottle, like a 2-liter soda bottle, or a glass bottle, and leave it out in the sun for 4 hours (8 is better). The ultraviolet will kill most pathogens.
If you mean no solar energy because the skies are dark, you can use ordinary Clorox. Just 8 drops to a gallon of water, and let it stand. If you can let it stand in the sun, so much the better. See the link below.
My first answer would be with electricity, but I’m guessing that since you are throwing in the solar power, electricity is not even an option. Therefore you would have to filter it that is if by purifying you mean removing all contaminates you would have to filter. If by purifying you simply mean kill anything that is alive you can use chemicals such as chlorine or boil the water by fire.
You can use iodine tablets, add a small amount of bleach, boil it, or use an ultrafilter.
