Common Water Disinfection Methods
You can purify drinking water in more ways than one. For the evaluation of the available treatment methods, you may consider the points given below. These pointers can help you disinfect your water. Read on to find out more.
Purpose of Water Disinfection
- It destroys different types of pathogens found in water.
- It works great irrespective of the condition or composition fluctuation of the water.
- It works within the given water temperature range.
- It doesn’t make the water unpalatable or toxic.
- It’s easy to handle and is safe.
- It’s easy to determine the amount of harmful elements in the water.
- It offers protection against contamination of water.
Although some filtration techniques can help kill infectious organisms in water, know that they can’t be a good alternative to disinfection. Given below are some affective water disinfection methods.
Pour the water in a container and put it over heat. Turn up the heat to bring the water to a boil. Keep boiling it for at least 15 minutes for proper disinfection. Although boiling won’t remove the organisms, they can kill them. As a result, they won’t cause any illness to you.
This technique works much better than the previous one. We know that sunlight can destroy different types of bacteria found in water. The exposure to the UV light kills the DNA structure of the harmful organisms. The types of organisms this method kills include giardia, cryptosporidium, yeast, algae, mold, viruses and bacteria.
Generally, UV light doesn’t affect heavy metals, chlorine and other chemical-based contaminants. Therefore, the UV light can be applied along with other types of filtration. For proper disinfection, make sure that the water is free of color and turbidity or some bacteria may be left untouched.
Disinfection with the Chlorine Method
Chlorine can also help disinfect water. Although chlorine is dangerous, it can work like a powerful oxidant, which is what makes it quite effective. Typically, the use of chlorine as a powerful disinfectant is quite common these days. This chemical is commonly used in many water disinfection methods.
Although chlorine kills harmful bacteria, it doesn’t kill some types of cysts and chemicals. Therefore, you can use multiple methods to achieve the desired results. For instance, you can try chlorine dioxide.
Ozone Water Disinfection
Another common water disinfection method is the application of ozone. O3 is an unstable molecule, which is what makes it toxic for water organisms. Actually, ozone has a great ability to disinfect water. You can product ozone using the UV light and oxygen. The good thing about ozone is that it is a lot safer than chlorine. The use of O3 is quite common as an effective water treatment method.
Apart from the methods listed above, you can also use a water disinfectant machine. You can buy these machines to purify your drinking water without investing a lot of effort. The good thing about these machines is that they are quite easy to use. So, you can try one out to meet your needs.
