Greensand plus – the best iron removal filter media?

Greensand plus for iron removal

Greensand plus iron removal filters are the best choice for removing iron, manganese, hydrogen sulfide and even arsenic in some conditions from water.

Iron in higher concentrations can make the water unpleasant to drink, have a very negative effect on many technological processes, especially in the food industry, textile industry, boiler rooms, car washes, etc.

Removing iron from water doesn’t have to be a problem. By choosing the right greensand plus iron removal system, all problems related to the formation of iron deposits can be easily solved.

What is Manganese Greensand Plus?

Manganese greensand plus is a special purple gray filter media that catalytically oxidizes soluble iron and manganese to the form of insoluble hydroxides, and simply filters them on the media layer itself in contact with the manganese dioxide coating of the silica sand core.

Simply put it is a silica sand core with a manganese dioxide coated surface. The manganese dioxide coating is the place where the magic happens. It converts the iron and manganese from soluble form to an insoluble form and filters is out on the media itself.

Manganese greensand plus iron removal filters, in addition to removing soluble iron, can remove manganese, ammonia, hydrogen sulfide and arsenic from water.

It’s operation can be done in two ways: intermittent or continuous regeneration. In both ways an oxidizing agent (chlorine or potassium permanganate) is used.

Applications of Manganese Greensand

Manganese greensand is commonly used in well water treatment systems for the removal of soluble iron, manganese, and hydrogen sulfide from groundwaters.

This filtering media is also used in other water treatment applications, including the treatment of industrial process water, municipal water supplies, and swimming pool water.

The use of manganese greensand and its manganese dioxide coating provide numerous benefits, including improved water quality, reduced maintenance requirements because of it’s silica sand core which provides higher differential pressures, and increased efficiency in water treatment processes.

In industrial use it is often used to protect other water treatment equipment like water softeners or reverse osmosis systems from iron deposits.

Hydrogen Sulfide Removal

Manganese greensand is a special type of filter media with a silica sand core and its manganese dioxide coated surface.

This manganese oxide oxidizes hydrogen sulfide gas to solid sulfur particles, which are then filtered out by the manganese greensand filter. The oxidized sulfur particles can then be removed using a manganese greensand or zeolite filter.

A point of entry filtration system containing manganese greensand can remove up to 10 ppm hydrogen sulfide in addition to iron and manganese. This method of it’s removal is excellent for high concentrations of hydrogen sulfide above 6.0 mg/L, and it is similar to chlorination in its effectiveness.

Manganese greensand is an environmentally safe solution for hydrogen sulfide removal. Unlike other methods, such as chlorination, manganese greensand does not produce any hazardous byproducts, making it a safer option for the environment and for your health.

Who am I?

I am working as a water treatment technical manager and I have more than 25 years of practical experience in water purification.

After many years of experience in water treatment and purification, I want to share some of my knowledge and get people to know the real importance of water quality.

Water quality and water treatment are very complex themes, so it is important to explain them on an easy-to-read level.

On this blog, you will find many understandable, easy-to-read information about water purification.

I hope you enjoy it and thank You for reading.
