Different Methods of Removal of Hydrogen Sulfide from Water

There is no doubt that hydrogen sulfide is a nuisance that we have to learn to live with. Though at lower doses, this gaseous substance may not be harmful, quite often the contamination levels go beyond the threshold levels. When this happens it could turn quite nasty and even dangerous. Even at low levels, the quality of drinking water in wells starts smelling of rotten eggs and in most cases, the reason is the presence of hydrogen sulfide. It is therefore important to find out the sources of contamination and take action accordingly. This foul-smelling gas is emitted when bacteria feed on the sulfur in the water. Further, they are also capable of thriving in very low oxygen environments. They are generally found in plumbing systems and wells. In many cases, hydrogen sulfide may not be noticeable in the water. The chemical reactions that take place in hot water may the reason for that rotten egg smell. This is why it is common to see water heaters having aluminum rods. These rods are capable of reducing hydrogen sulfide quite significantly and thereby reducing the foul smell that we often come across in hot water.

Water Treatment For Overcoming This Problem

Water is a big source of hydrogen sulfide contamination. However, water can easily be treated and several treatment processes are available. You can choose the most efficient one based on the levels of concentration of hydrogen sulfide. It would be better to treat the problem using POE solutions because it is an aesthetic odor problem that impacts many homes. You may have to do some research and then choose the right treatment device. It should not only clean and purify water, but also should be able to take care of hydrogen sulfide contamination.

Filtration And Continuous Chlorination

Oxidation is considered to be one of the most common and successful methods of removing hydrogen sulfide from water. Some special chemicals are used for converting dissolved hydrogen sulfide gas and make them into sulfide. This form of sulfide can be easily removed when the water filtration processes happen. Chlorine is one of the most commonly used methods for oxidizing water and it converts hydrogen sulfide and makes it into an insoluble fiber. However, there are a few things that we need to bear in mind. Chlorination methods and systems have to be maintained properly. The tanks containing chlorine solutions must be cleaned regularly and the mechanical filters also should be backwashed properly. Otherwise, it will have sulfur particles attached to it and this could lead to other complications.

Use of Potassium Permanganate With Filtration

Potassium permanganate like chlorine is another efficient way of h2s removal from the contaminated source. It is injected in the right quantity into the water using a small feed pump capable of handling chemicals. It should be in contact with the water for at least 15 minutes after which the sulfur compound comes out separately. These are oxidized and then can be removed with the help of a zeolite filter or with the help of manganese greensand.

The Final Word

We are sure that the above would have given our readers some idea about ways and means by which it is possible to remove hydrogen sulfide from the water.
