锰砂滤料
锰砂滤料是采用国内优质锰砂矿、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、破碎、干燥、磁选、筛分、除尘等工艺加工成砂,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。 锰砂滤料外观黑褐色,近圆形,主要成份是二氧化锰,含量在25%-40%之间。

锰砂用途
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。
锰砂除铁是一种接触催化除铁工艺,适合于地下水含铁量小于20mg/L的除铁。天然锰砂中含的高价锰
能将水中的二价铁氧化成三价铁,同时在表面形成有催化作用的“活性滤膜”,进一步提高了除铁效果。含铁
水经曝气后,只经锰砂一次过滤,就能完成全部除铁过程。
锰砂工作原理
铁以Fe2+的状态曾于地下(井)水中,其水有异色异味,污染离子交换树脂而降低交换能力,长时间后生成铁垢,影响传热,能腐蚀设备。而锰砂中的MnO2与Fe2+发生氧化还原反应,使Fe2+变为Fe3+并生成 Fe(OH)3沉淀,从而利用锰砂过滤器的反冲洗功能达到去除净化的目的。 用于地下水除铁和除锰的天然锰砂滤料,其锰的形态应以氧化锰为主。含锰量(以MnO2计,下同)不应小于35%的天然锰砂滤料,既可用于地下水除铁,又可用于地下水除锰;含锰量为20%~30%的天然锰砂滤料,只宜用于地下水除铁;含锰量小于20%的锰矿砂则不宜采用。
锰砂滤料使用注意事项
天然锰砂池的反冲洗时间一般为5-15分钟。天然锰砂滤料表面的“活性滤膜“结构比较硫松,能在长时间的冲洗中破坏,所以滤池的反冲洗应以不破坏滤料表面的“活性滤膜”为度。否期会引起滤后水质严重恶化,在地下水除铁滤池中,应采用不易为铁质堵塞 的 配水系统形式。推荐采用上设承托层的管式大阻力配水系统和格 栩式或孔板式小阻力配水系统。

Manganese sand filter material
Manganese sand filter is the use of domestic high-quality manganese placer, grain density, high mechanical strength, strong chemical activity, not easily broken, insoluble in water, natural manganese sand, the washing grinding removing impurity, crushing, drying, magnetic separation, screening, dust and other processing into sand, and the processing of manganese sand according to certain gradation and. It has the most ideal gradation proportion of water treatment filter material, so that it has the largest specific surface area, the strongest cutting capacity, the largest oxidation catalytic activity and the lowest reverse washing rate in the unit volume. Manganese sand filter looks dark brown, nearly circular, the main ingredient is manganese dioxide content between 25%-40%.
Manganese sand filter material uses
Manganese sand filter is mainly used to reduce the 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, long time drinking containing iron with high manganese content in water will seriously affect the health of the body.
Manganese sand except iron is a kind of contact catalytic iron removal process, which is suitable for the iron content of groundwater with less than 20mg/L. The high manganese content in natural manganese sand can be oxidized to ferric iron in two valence iron, while the active membrane is formed on the surface of the surface. After aeration of the iron containing iron, only by a manganese sand once filtered, can complete all the iron removal process.
