Most people are uneasy about drinking water that has strange color. So, if you’re living in a city, color coming from your kitchen tap is most likely the result of water pipes. Copper pipes leave a blueish or greenish color, while red water mostly comes from ageing iron pipes.
However, the water may be cloudy for some time, and this means there is some air crossing in the city’s waterline. Therefore, the test is to run the water into a glass and watch it as it clears, if the water is clear from the bottom upward, then it is air.

How To Remove Color From Water
People can keep their drinking water safe & healthy using different water filtration systems. Since the color of water doesn’t necessarily reflect whether it's drinkable or not.
Below, we have discussed some filtration methods that you can use to remove color from your water.

- Reverse Osmosis Filtration:
A reverse osmosis filtration system is effective at removing a range of colors from drinking water. Not just this, it also eliminates all the impurities making water safer and tastier to drink.

- Oxidizing Filtration:
Oxidizing filtration is a pretty useful method when your water contains small amounts of hydrogen sulfide. The oxidizing process is perfect for removing sulfur, which gives the water yellowish color.
- Mechanical Filtration:
Mechanical filters also known as turbidity filters that help to strain particles from water while producing clearer and more healthy water. These filters use sand, paper, spun, or compressed glass wool to remove contaminants from water.
Another way to remove color from water is by boiling it. This method is often used to remove rust stains from fixtures, but it can also be used to remove color from water itself.
