"Poison" the water with something like chlorine, and wait at least 20 minutes. Thi is suitable for use in water distribution systems, to keep the bacteria from breeding. Add something like ozone, chlorine dioxide, or hypochlorite ion, and wait about a minute. The bacteria will be unable to reproduce and will be bleeding to death. Pass the water stream in front of a very intense UV-254nm lamp. The DNA of the bacteria will be destroyed (if the water is very clear), and they will quickly die. Pressurize the water stream to 80,000 psi for a couple of minutes. Kills everything, since diffusion will entirely overpower the Na+/K+ ATPase pump... sort of like a person drinking too much water. Heat the water to 140 °F or higher for a few minutes. This is also called "pasteurization". Pass the water through ultra filtration or reverse osmosis, which allows small water molecules but not something as large as a bacterium or spore. You can also add great gobs of salt, which kills or drives the bacteria into a state that they can no longer reproduce until the salinity drops. But you cannot drink it then either.
What else can I help you with?
Which has more bacteria rainwater tap water or purified water?
Rainwater typically contains more bacteria than tap water or purified water, as it can pick up bacteria from the atmosphere and surfaces it comes into contact with during collection. Tap water is treated to meet safety standards and purified water goes through additional filtration processes, which can reduce the bacterial content.
Does boiled water make tap water cleaner?
The boiling point of tap water is higher than that of distilled water because tap water contains many minerals and bacteria that have higher boiling points than of water in its natural state and thus they collectively increase the boiling point of water. I would suggest researching the boiling points of substances in tap water such as nitrate, chlorine, fluoride, led, etc. because these substances are not in distilled water.
Which process is used in water treatment to kill bacteria?
Chlorination is commonly used in water treatment to kill bacteria. Chlorine is added to the water to disinfect and kill harmful microorganisms, making the water safe for consumption.
What is added to drinking water to kill the bacteria in it?
Bacteria (usually) can be killed with ordinary soap or diluted cholrine bleach.
What happens when tap water is treated with alum?
the dirts and bacteria in the water would coagolate or clump together~it is also a method of purifying water..
Is it best to boil tap water before drinking for safety reasons?
Boiling tap water before drinking can help kill harmful bacteria and parasites, making it safer to drink.
How much chlorine in tap water?
The amount of chlorine in tap water can vary, but it is typically maintained at a level of 0.2-4 milligrams per liter to ensure water safety. Chlorine is added to disinfect water and kill bacteria and viruses before it reaches your tap.
What is the element which is used to kill germs in tap water?
i should think clorine - it is used in swimming pools in killing any germs
Do plants grow best in tap water or salt water?
Tap water, salt water will kill them
Which has more bacteria rainwater tap water or purified water?

Tap water is treated to meet safety standards and purified water goes through additional filtration processes, which can reduce the bacterial content.
Does tap water have chlorine?
In some areas, water purification plants use first chlorine, to kill bacteria, and then ammonia to neutralize the chlorine. That leaves traces of chloramine in the tap water. This generally considered harmless to humans, but can kill tropical fish, which is why you have to treat tap water before using it for aquariums. However, as a result of the addition of the ammonia, there is no free chlorine in such tap water.Answer: In most places, yes there is trace amounts of chlorine left in tap water (used in the cleaning process) by the time it reaches a house for use.This can either be filtered out at the tap, or simply put the water in a pitcher in the fridge and the chlorine will evaporate within 24 hours. (do not seal the water in a bottle or you will trap the chlorine, use a pitcher with a light fitting lid so there is air transfer)
Does water kill bacteria?
I think it will kill.
Why does tap water and pool water typically test positive for chlorine?
Chlorine is used as a disinfectant. It's added to the mains water supply to kill off any bacteria that the treatment plant missed. The same with the water in swimming pools - except it's in a higher concentration.
Does boiled water make tap water cleaner?
The boiling point of tap water is higher than that of distilled water because tap water contains many minerals and bacteria that have higher boiling points than of water in its natural state and thus they collectively increase the boiling point of water. I would suggest researching the boiling points of substances in tap water such as nitrate, chlorine, fluoride, led, etc. because these substances are not in distilled water.
What temperature is required to kill bacteria in water?
The temperature required to kill bacteria in water is typically 140F (60C) or higher.
What element used to kill germs in tap water?
Chlorine is commonly used to kill germs in tap water. It is added to water treatment facilities to disinfect the water and make it safe for consumption.
Does tap water naturally become better drinking water after it sits for a period of time?
To the best of my knowledge most tap water contains chlorine, which is added at a water treatment plant in order to kill bacteria and other unhealthy organisms. If you allow tap water to sit for an extended period of time (dependent on amount of water..approx. 1-2 days per gallon), the chlorine will actually evaporate. While having the chlorine in tap water for the purpose of killing of contaminants is good, I think once it is out of the tap it is better to let it evaporate. After all, chlorine is a poison appropriately to kill living things.
