Greensand Plus media is a powerful tool for water treatment, known for its ability to remove iron, manganese, hydrogen sulfide, and arsenic from water. But what makes this media so effective, and how can you use it to improve the quality of your water?
In this article, we’ll explore Green sand Plus media and its applications in water treatment. Keep reading to discover the benefits of this remarkable filtration media and how it can help you achieve cleaner, safer water for your home or business.
This article is written by Miroslav Radovanovic, a water purification technical manager with over 25 years of experience in water treatment.
Manganese Greensand for iron removal, Manganese removal and Arsenic removal
Green sand plus media for iron removal is the best choice for removing soluble 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.

What is Manganese Greensand Plus?
Manganese Greensand plus filter media is a special purple – gray colored 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 uses the oxidation reduction reaction to convert the iron and manganese from soluble form to an insoluble form and filters it out on the media itself.
Manganese Greensand plus iron removal filters, in addition to removing soluble iron, can remove manganese, ammonia, hydrogen sulfide, arsenic and radium 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 Plus
Manganese Greensand Plus filter media is commonly used for removing soluble iron in well water treatment systems, but also for the removal of manganese, hydrogen sulfide, arsenic 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 with Greensand plus
Manganese greensand media 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.
Arsenic removal
Arsenic removal from water can be done by filtering water through Greensand plus media filters.
The main condition to remove arsenic is the quantity of iron. According to my experience about 1 mg/l of iron is required to remove about 20 micrograms of Arsenic.
If there is not enough Iron content in the water, it can be added by a dosing pump to the required ratio.
More about Greensand plus
Greensand Plus Media has received the WQA Gold Seal Certification for compliance with NSF/ANSI 61.
This certification ensures that the media and the method of filtration meet the required water quality standards. The greensand media is available in easy-to-handle 1 or 2 cubic foot bags.
| Service Flow Rate: | 2-6 GPM/ft2 (8-12 GPM/ft2 short term) |
| Flow Direction: | Downward Flow |
| Typical Pressure Drop: | <3 psi |
| Backwash Flow Rate: | 12-14 GPM/ft2 |
| Typical Freeboard: | 40% |
| Recommended Bed Depth: | 30 to 36 Inches |
| Maximum Feed Temperature: | 100F |
| Recommended pH: | 6.2 to 8.5 |
| Weight: | 88 lbs per Ft3 |
One of the added benefits of using Greensand Plus Media is that it requires no changes in backwash rate or times compared to Greensand filter media.
This means that systems currently using manganese greensand can switch to Greensand Plus Media without making any changes to their current system.
The core of Greensand Plus Media allows it to better withstand waters with higher differential pressures, which may allow for a longer run length.
