Top 5 simple and effective ways to treat Manganese in water in 2024

Simple Ways to Treat Manganese in Groundwater

Using Water Filtration Materials

There are various types of water filtration materials available on the market that are used in treating manganese in groundwater. Some notable ones include: Quartz sand, gravel, manganese sand, Birm media, and Pyrolox media. Each filtration material has its own characteristics and advantages, as follows:

Manganese Sand

This material has a chemical composition of KMnO4. It is widely used in treating manganese in water.

Not only does manganese sand remove manganese, but it can also eliminate musty odors in water by directly oxidizing reactions through contact. As a result, manganese is precipitated and retained in the water filtration layers.

Birm Media

Birm media is used to remove dissolved iron and manganese in groundwater.

The operating mechanism involves catalyzing to enhance the oxidation reaction of Mn2+ to Mn4+ in the form of precipitates. Subsequently, the solid substances produced from the reaction are removed through backwashing.

Pyrolox Media

Pyrolox media is effective in removing heavy metals in water, especially manganese, iron, arsenic, and hydrogen sulfide.

Here, Pyrolox media acts as a catalyst to oxidize dissolved iron and manganese into precipitates that can be easily removed from groundwater.

Aeration Method

Aeration essentially enhances the oxidation process in water. This creates conditions for Mn2+ to oxidize into Mn4+, forming less soluble compounds like Mn(OH)4 or MnO2, which can then be retained using filtration tanks.

Some aeration methods for treating manganese in groundwater include:

• Using rain spray systems, showerheads, or misting systems to introduce water into settling tanks, filtration tanks, and finished water tanks.
• Aerating water to enhance the oxidation-reduction process.
• Using rain spray systems combined with a fan system to enhance the oxidation process.
• Aerating by using various filter surfaces.

Chemical Treatment

There are two basic methods of using chemicals:

First Method

Using a group of strong oxidizing chemicals. For example: Cl2, KMnO4, O3…

These chemicals, when introduced into water, can initiate reactions to reduce manganese. Consequently, this element can be removed from water through filtration methods.

Second Method

Using lime powder to reduce manganese. According to research by experts, to improve water quality, the majority of people often apply manganese removal methods in combination with stabilization and water softening processes. This helps enhance the purity and safety of the water source.

Note: Treating manganese in water with chemicals can affect water quality if the dosage is not carefully controlled. Therefore, thorough research is necessary before use.

Most Effective Manganese Treatment in Groundwater

Filter Tank System

The filter tank system is a highly effective method for treating manganese in groundwater and is commonly used in rural areas where well water and dug wells are the main sources of domestic water supply.

Structure

The filter tank system is constructed with cement and consists of 3 compartments: settling, filtration, and post-treatment water storage compartments.

The settling compartment usually includes rain showers or showerheads. It is combined with gravel, quartz sand for water filtration, and fine sand. The post-treatment water storage compartment needs to be tightly covered to prevent dust and dirt from entering after treatment.

Operating Principle

The operating mechanism of the filter tank system is as follows:

• Groundwater pumped from the well flows through the rain spray or showerhead into the settling tank. At this point, the water comes into contact with air, causing manganese in it to oxidize and precipitate into sludge.
• Part of the sludge settles in the water and then moves to the filtration compartment. The filtration compartment contains water filtration materials that can remove suspended solids and sediment, making the water clearer.
• After treatment, this water source is directed to the post-treatment water storage compartment through pipes.

Comprehensive Water Treatment System

Currently, the most effective method for treating manganese recommended by experts is the comprehensive water treatment system.

This system uses filter tanks made of high-quality stainless steel or composite with excellent durability, long-term resistance to corrosion, and good corrosion resistance. It contains many essential filtration materials that help treat metal ions, chemicals, dissolved organic matter, inorganic substances, sediments, and microorganisms. Particularly, manganese and iron are abundant in groundwater sources.

The system operates automatically, can backwash and regenerate filter materials to increase efficiency and improve water quality.

The water source treated through the comprehensive water treatment system meets the standards of the health department and is used for domestic purposes, cooking, etc.
