How To Remove Hydrogen Sulfide From Water

Also known as H2S, hydrogen sulfide is a harmful and gaseous substance that gets dissolved with other gaseous and liquid substances. Hence, it is extremely important and vital to find out ways and means by which it can be removed from the water and other sources. There are many occasions when well water users find that hydrogen sulfide gets mixed with the water that they use for drinking, cooking and other purposes. Though it may not be a big health risk, it could pose problems if the quantity of H2S increases beyond the permissible limit. We need to understand that even a small amount of around 0.05 mg/L could lead to foul-smelling water.


The well-water could become unfit for use because of the presence of hydrogen sulfide even in small quantities. It could smell like rotten eggs and could also damage and discolor kitchen sinks, bathroom sinks and discolor them. It also could lead to corrosion of metals like steel, iron, copper, brass, and silver. Food could task and look different and it could also make the resin bed of water filter smell bad. High levels of concentration of hydrogen sulfide could lead to nausea and other potentially serious illnesses. Hence it is important to find out the best method for removing H2S from well-water and make it fit for human consumption.


Ascertain The Source

 To begin with, you must be sure that the source of hydrogen sulfide mixture has happened in the well-water and not because of any other reason. In some cases, your water heater could be the reason for the production of such gaseous substance. It is caused because of sulfur-reducing bacteria. Hence, identifying the source of the problem is important and only then should the next step of cleaning should happen.


Simple Cleaning And Purification Methods

 Installing a chlorinator in between the ingress pipe that supplies water from the well to the holding tank is a simple solution. When there is a reaction between the chlorine that is released in the water and the hydrogen sulfide present in well water, you will have a byproduct. It will be odorless, tasteless and yellow particle that can easily be removed by a good quality water filter. You can also add other chemicals including potassium permanganate and hydrogen peroxide into the water. This will help in oxidizing and removing the concentration of hydrogen sulfide, however, small or insignificant it might be. Filtration, on the other hand, will help in removing particles from the water.


A Good Aeration System Can Also Help

 Take the help of a professional and install a quality aeration system. It will help eliminate hydrogen sulfide gaseous substance with the help of a ventilation system. However, chlorination might still be required. Aeration may not be the first choice for many homes because it is very expensive. But in case nothing else works, it could be the best option to remove hydrogen sulfide from well water.


At the end of the day, there is a need to find out ways and means by which you can help to make the well water safe, pure and fit for human consumption. Removing even trace quantities of hydrogen sulfide without any doubt is an option that should always be kept in mind.
