How to Remove Hydrogen Sulfide

How to Remove Hydrogen Sulfide

Once in a while, many of us come across water that smells odd. In fact it could smell like a rotten egg. In most cases it is because of a substance called hydrogen sulfide gas. Hydrogen sulfide is a naturally occurring substance in some types of rock and soil where groundwater is available. This dissolves over time and therefore it gets released into the groundwater. Hydrogen sulfide could also happen because of fuel tanks that are leaking, landfills, septic systems that are old and because of some works that are done in chemical labs. These are known as community hazards. However, because of its odd smell it could cause problems as far as drinking and potable water is concerned. Hence, there is a need to find out ways for easy, efficient and sustainable hydrogen sulfide gas removal from various sources so that the problem of foul smelling ground water can be addressed adequately.


Treatment Methods & Options

If excess concentration of hydrogen sulfide is present in the water supply that comes to your home or other places, you can use any of the following options to treat the problem.


1)      The simplest and best option is to look for an alternate source of water supply. If this is expensive and not possible, you can look at options for treating the water and removing the impurity. In case you are going in for an alternate water supply by inserting pipes in a nearby location, you must ensure that the water is analyzed properly to rule out the occurrence of the problem again.

2)      The next option is to go in for a whole-house water treatment system. This is perhaps one of the most efficient and permanent solutions for removing hydrogen sulfide from your water supply source. It also is a cost effective method and you can be reasonably sure that your family will be able to get the best possible quality of water.


There Could Be Some Temporary Solutions Too

There is a method known as shock chlorination that could be helpful in temporarily controlling the problem of hydrogen or sulfide contamination in water. This is particularly useful when you have a well from where water is supplied to your home. You may have to use a combination of high levels of chlorination along with the right turbulence and mixing. It should offer temporary relief but the permanent solution lies in identifying the root cause of the problem and rectifying it. In case it happens to be a permanent problem, the whole-house water treatment is perhaps the best option.


Other options include installation of activated carbon filters. This should take care of the problem. However, the carbon filter should be replaced regularly. The frequency of replacement of the carbon filter would depend on a number of factors such as daily consumption of water and the level of concentration of hydrogen sulfide in the water.


If the levels of hydrogen sulfide concentration is around 5 to 7 ppm then it may be a good idea to make use of an oxidizing filter. These are commonly used for treating excess iron in water. The filters may help in converting the hydrogen sulfide concentration into tiny particles of sulfur and these get trapped inside the filter.



While there is no doubt that more than normal concentration of hydrogen sulfide is a nasty problem, it can be controlled and remedied quite easily.
