Working Principle
The manganese sand filter operates on a fundamental principle of adsorption, oxidation, and filtration. Serving as the filtration medium, manganese sand effectively captures manganese ions present in water. This process is facilitated by the oxidation of soluble manganese ions (Mn2+) into insoluble manganese dioxide (MnO2), which are subsequently trapped by the manganese sand, allowing only purified water to pass through.
Chemical Formula: The primary component of manganese sand is manganese dioxide, with a chemical formula of MnO2. This compound plays a pivotal role in the oxidation process, essential for converting soluble manganese ions into insoluble forms that can be efficiently removed from the water matrix.
Water System Application
The versatility of the manganese sand filter lends itself to diverse applications across various water systems. From municipal water treatment facilities to industrial processes, agricultural irrigation, and residential settings, this filtration technology offers a comprehensive solution to mitigate manganese contamination and ensure water quality compliance.
Prevention Measures
Effective management of manganese contamination necessitates a proactive approach encompassing comprehensive monitoring, robust filtration infrastructure, and stringent control measures. Implementing stringent regulatory frameworks and investing in advanced filtration technologies like manganese sand filters are integral to preventing manganese ingress into tap water systems.
Dangers of Manganese in Water
Elevated levels of manganese in water pose multifaceted risks, ranging from aesthetic concerns such as staining and odor to more profound health implications. Prolonged exposure to high manganese concentrations has been associated with neurological disorders, particularly in vulnerable populations such as children and the elderly.
Methods
In addition to manganese sand filtration, various complementary techniques, including oxidation, ion exchange, and chemical precipitation, are employed to remove manganese from water systems. Each method offers distinct advantages, tailored to specific water quality requirements and operational constraints.

When the system is in the filtering state, the unfiltered water passes through the upper water distributor, cooperates with the spherical shell, and reaches the packing layer in the filter in a state of nearly advection. When water flows through the packing layer, impurities are trapped within the packing layer. The collector at the bottom of the filter collects the filtered water evenly and flows out. Advection filtration determines that the filter can still achieve good filtration effect under high flow rate.
As impurities continue to accumulate in the packing layer, the head loss (ie differential pressure) will continue to increase. When the pressure difference reaches a certain set limit or the filtration time reaches the set value, the system will automatically switch to the backwashing state to clean the packing layer and remove accumulated impurities. For the system, regular backwashing is required to remove Accumulated impurities are necessary.
When the system enters the backwash state, the on-off position of the three-way valve is changed through PLC control (the inlet is closed, the sewage port is opened), and the filtered water in other filter tanks flows into the filter tank to be backwashed. The packing layer of the filter unit backwashed by the system pressure is washed up under the impact of the water flow, and the impurities are discharged through the sewage outlet of the three-way valve.
