供35%/40%/45%天然锰矿砂锰砂滤料

锰砂简介：

锰砂滤料是采用优质天然锰矿石加工而成，外观呈褐色，对于地下水除铁、除锰过滤有独特的效果。

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Zui理想的级配比例，使它在单位体积内有Zui大的比表面积、Zui强的截污能力、Zui大的氧化催化作用和Zui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35%-45%之间。采用锰砂滤料处理地下水，工艺简单，操作方便，工程造价低，长效稳定，服务周期在5年以上，易于管理，不填加任何化学药剂即可达到去除水中铁、锰、砷等有害物质的目的，水质完全达到国家饮用水标准，是非常好的地下水处理滤料。

锰砂的应用：

天然锰砂是一种很强的氧化剂，能对水中二价铁起氧化作用，常用于饮用水除铁、除锰过滤装置，地下水除铁除锰净化水质使用。

使用锰砂的注意事项：

锰砂的使用的年限，对含铁浓度高的地下水一般为3~5年，对含铁浓度低的地下水，使用年限更长，有的已逾十年。在有的天然锰砂滤池中，滤层上部的锰砂会逐渐形成球状的“锈砂”，“锈砂”表面有一层“活性滤膜”，仍具有接触催化除铁能力，所以，形成“铁砂”，不是天然锰砂失效的标志。当”锈砂“长大致使滤料粒径过粗而影响除铁效果时，才有必要更换部分滤料。所以，在我们的施工过程中要注意是否有“锈砂”的存在，如果有的话一定要辨别清楚“锈砂”的大小，如果是小的规格，可以继续使用，可以减少我们的工业成本，如果是大的规格，就要换掉，以免影响过滤水质。

manganese sand introduction:

manganese sand filter material is made of high-quality natural manganese ore processing and become, the appearance of browning, for groundwater in addition to iron and manganese removal filter has a unique effect.

manganese sand filter material is to use domestic high-quality manganese placer, grain density, mechanical strength, chemical activity is strong, not easy and broken, insoluble

the natural mengkuangsha in water. the washing grinding removing impurity, crushing, drying, magnetic separation, screening, and dust removal etc. craft processing into sand. to process the good manganese sand according to certain grading compound and into. it has water treatment filter material is the most ideal grading scale, make it in the unit volume has the biggest specific surface area, the strongest section carrying capacity, the biggest oxidation catalysis and minimum back flush wastage rate. manganese sand filter material appearance dark brown, nearly circular, the main ingredient is the content of manganese dioxide, between 35% and 45%. the manganese sand filter material processing groundwater, simple process, easy operation, low engineering cost, long-term stability, the service cycle in 5 years, easy management, do not add any chemicals can fill to remove water iron, manganese, arsenic, the purpose of the harmful material such as water quality completely meet the national standards for drinking water, groundwater is a very good deal with filter material.

manganese sand in physical and chemical indicators:

close degree 2.66 g/cm3 broken broken rate of 1.0% or less

dense degree of 1.85 g/cm3 ground loss rate of 1.0% or less

containing 2.5% or less amount of mud mno2 30-40%

manganese sand applications:

natural manganese sand is a strong oxidizing agents, to the water ferrous iron on oxidation, often used for drinking water in addition to iron and manganese removal filter device, groundwater for removing iron and manganese purification of water use.

using manganese sand attention items:

manganese sand use fixed number of year, high concentration of iron groundwater is commonly 3 ~ 5 years, the iron concentration low groundwater, service life is longer, some already more than ten years. in some natural manganese sand filter, filter upper manganese sand will gradually formed globular "rust sand", "rust sand" the surface has a layer of "active filter film", still have contact catalytic iron removal ability, so, in the form of "iron", not natural manganese sand sign of failure. when rust sand "grow up the filter material particle size is too thick and influence in addition to iron effect only when it is necessary to replace part of the filter material. so, in our construction process should pay attention to whether there is a "rust sand" existence, if any, must distinguish clearly "rust sand" size, if it is a small specifications, can continue to use, can reduce the cost of our industry, if it is big specification, will change, so as not to affect the filtering water quality.
