Product Features

1.Multiple specifications to choose from: strong adaptability

Particle size allows Multiple Size Manganese Sand to be split into several standards to satisfy various water treatment systems. Common criteria are 0.6–1.2mm, which is appropriate for systems requiring high effluent quality standards and hence better filtration accuracy;

It is typically used as an intermediary filter layer, measuring 1-2mm, and is mostly utilised in the primary filter layer. It is also used for coarse filtration systems or bottom support layers, measuring 4-8mm.

Apart from improving filtering effectiveness, this multi-spec design maximises hydraulic dispersion, therefore extending the entire lifetime of the filter material.

2. High manganese content and strong catalytic ability

Active manganese oxide, which is more than 35% high-quality manganese sand, can quickly promote oxidation, helping to remove iron and manganese effectively with little or no oxidant (like chlorine gas or potassium permanganate) and lower operating expenses.

3. High mechanical strength and long service life

Hard and dense, manganese sand filter material has a low crushing rate of less than 1.0%, good pressure resistance, and is fit for long-term running circumstances. It can still have a pleasing physical form, cut the frequency of filter material replacement, and save maintenance expenses after several back washings.

4. Moderate porosity and excellent back washing performance

We create a reasonable gap structure between the filter materials to guarantee smooth water flow and improve the capacity to trap contaminants. The speedy recovery of the filter layer during back washing and its non-clogging behaviour serve to prolong the running cycle of the filter tank.

5. It is natural, environmentally friendly, non-toxic, and harmless.

Natural mineral processing product manganese sand satisfies safety criteria for drinking water treatment without dangerous chemicals and has no side effects on human health or the environment during usage.

Analysis and Application of Inlet Water Quality

Mostly used to remove iron and manganese elements from water, multiple-sized manganese sand is appropriate for the following kinds of inlet water quality:

Groundwater

Most groundwater contains high iron content and somewhat low manganese levels; hence, oxygenation treatment is necessary for the water quality to have enough dissolved oxygen. Manganese sand can catalyse the conversion of Fe²⁺ and Mn²⁺ into Fe(OH)₄ and MnO₂ precipitates that can be filtered away, therefore accomplishing effective removal under suitable pH and oxidation conditions.

Surface water and well water

Well water and surface water in small water supply stations and rural drinking water projects sometimes contain manganese and iron. Multi-layer manganese sand filter medium, particularly in places without water treatment equipment, can accomplish water purification without the use of chemicals.

Industrial water

Special needs for water quality, such as controlling the iron and manganese levels in raw water, apply to sectors such as electronics, electroplating, and chemical engineering. Pre-treatment systems can use manganese sand as a filter medium to ensure the uninterrupted operation of subsequent processes.

Filter system type matching

Various types of filtration systems also have certain specifications for the use of filter media. Because of its multi-specification qualities, manganese sand filter media is rather flexible in the following systems:

1. Gravity-based filtration system

The system is designed to drive water flow through water level differences, with basic system operation and low energy consumption, making it suitable for small and medium-sized water supply projects. While small-sized manganese sand (0.6–1.2mm) can enhance filtration accuracy, it's crucial to manage head loss.

2. Pressure filtration system

This system is suitable for industrial circulating water systems, large water plants, and more, offering outstanding treatment efficiency and a large water volume. The design flow rate will let one choose a 2-4mm main filter layer; a 4-8mm manganese sand support layer at the bottom guarantees filtering stability and strength.

3. Multimedia filter

Combining manganese sand with filter media such as anthracite and quartz sand creates a multi-media system for layered filtration that increases treatment efficiency. It is appropriate for situations requiring high effluent quality.

Filter speed requirements and recommended usage

Furthermore, with regard to the particle size and layer thickness of manganese sand media, the running speed of various processing systems has criteria:

1. Slow filtration (<10 m/h)

Appropriate for events requiring high levels of filtration accuracy, 0.6–1.2mm manganese sand is advised to be used to boost retention capacity, therefore fitting for drinking and well water purification.

2. Medium speed filtration (10-20 m/h)

Combining 1-2mm and 2-4mm manganese sand provides a balance between accuracy and efficiency, making it suitable for most conventional filtering systems.

3. Rapid filtration (>20 m/h)

Big pieces of manganese sand (like 4-8mm) are important as the main or support layer in strong, ongoing industrial systems to ensure clear water flow, stop blockages, and increase pressure difference.
