Product Information

Zeomangan Manganese Sand – Removes Iron and Manganese (Made in Taiwan)

Manganese sand is a reddish-brown granular filter media made from natural manganese ore through processing and screening. It is primarily used in water treatment, converting low-valent iron and manganese ions dissolved in water into high-valent precipitates through oxidation. These are then removed by filtration, reducing the iron and manganese content in the water. It has a wide range of applications, including treating groundwater, tap water, and drinking water. It can also be used as a filter media in industrial water treatment, effectively removing impurities such as iron, manganese, and hydrogen sulfide. 
Main functions and principles
  • Remove iron and manganese ions from water: Manganese sand uses its strong oxidizing ability to oxidize the divalent iron and divalent manganese ions in the water into trivalent iron and trivalent manganese ions, causing them to precipitate, and then separate them through adsorption and filtration of the manganese sand layer, thereby achieving the effect of purifying the water quality. 
  • Removal of hydrogen sulfide (H₂S): Manganese sand can also adsorb and remove hydrogen sulfide in water. 
  • catalytic oxidation: Manganese sand itself has catalytic oxidation ability and can accelerate the oxidation reaction process in water. 

 

Main application areas
  • Groundwater and tap water treatment: Used when the iron and manganese content in groundwater or tap water exceeds the standard to solve the red and black water problems. 
  • Industrial water treatment: Widely used in water treatment systems in the power, oil refining, food, printing and dyeing, papermaking, electronics, pharmaceutical and other industries. 
  • Aquariums and aquaculture: Used for water filtration in aquariums and fish and shrimp farming to maintain good water quality. 

 

Maintenance and regeneration
  • Regular backwashing: The sediment produced during the filtration process needs to be discharged through backwashing to maintain the filtration efficiency of manganese sand. 
  • Potion Regeneration: In order to maintain its oxidizing ability, manganese sand needs to be regenerated regularly using reagents such as potassium permanganate (KMnO₄). 

 

Manganese sand (manganese zeolite) is made by repeatedly mixing and calcining a solid, porous base material with high-grade manganese compounds. It can be used as a catalytic converter for soluble iron and manganese cations in deep well water. Furthermore, due to its inherent porosity, manganese sand (manganese zeolite) can also remove suspended solids from the water, making it suitable for use in both closed pressurized filtration systems and open gravity filtration systems. Generally, when iron and manganese levels in underground well water exceed specified limits, the water will appear red or black, necessitating the urgent need for iron and manganese removal. Manganese sand (manganese zeolite) offers highly efficient iron and manganese removal capabilities, resolving water quality issues.
