是采用国内质量优良、晶粒致密、机械强度大、化学活性强、不易破碎、不溶于水的天然锰矿砂。经水洗打磨除杂、干燥、磁选、筛分、除尘等工艺成砂。再把加工好的锰砂按一定的级配调合而成。它具有水处理滤料最理想的级配比例，使它在单位体积内有最大的比表面积、最强的截污能力、最大的氧化催化作用和最小的反冲洗流失率。
锰砂滤料外观粗糙呈褐色或淡灰色，常用于生活饮用水的除铁、除锰过滤装置，滤水效果非常良好。（注：MnO2≥35％既可除铁，又能除锰，MnO2≤30％）只能用于地下水除铁）锰砂滤料主要用于降低水中的铁锰铁和锰总含量，根据我国生活饮用水卫生标准规其铁含量≤0.3㎎/L，锰含量≤0.1㎎/L，长时间饮用含铁含锰量过高的水会严重影响身体健康.
Manganese sand filter material appearance rough brown or light gray, commonly used in drinking water in the life of iron removal, manganese removal filter, filter water effect is very good. (Note: MnO2 is greater than or equal to 35% can in addition to iron and manganese removal, MnO2 less than or equal to 30%) only for groundwater iron removal) manganese sand filter is mainly used for reducing water of iron manganese and manganese content, according to the China's drinking water health standards the iron content is less than or equal to 0.3 mg / L, manganese content is less than or equal to 0.1 mg / L, a long time drinking water containing iron with high manganese content in water will seriously affect the health of the body.
