锰砂滤料简介：
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35%-45%之间。
锰砂滤料的使用方法：
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。
锰砂里面含的天然二氧化锰能氧化水中二阶铁并沉淀除掉，使水清净。既可用于地下水除铁，又可用于地下水除锰；我厂生产的锰砂滤料是采用优质天然锰矿石为原料，经机械破碎多次筛选而成，外观粗糙多棱角，呈褐色，晶粒致密、硬度高、耐腐蚀、损失少、使用寿命长，在水中浸泡不溶解、过滤水中含锰量不增加，天然锰砂可说是最难溶于水的净化剂。具有良好的除铁、除锰性能，是地下水和工业用水含铁离子和锰离子进行除铁、除锰处理的必备产品。
当前使用天然锰砂除铁原理有二种：
一种是锰砂表面有一层活性滤膜，可起到很强的氧化作用；
另一种是锰砂本身对铁质起催化作用，将水中的二价铁催化成三价铁，并使三阶铁质附着于锰砂颗粒表面，起到除铁的目的。含量30%的天然锰砂滤料，只宜用于地下水除铁。

Manganese sand filter material description:
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 in water MengKuangSha natural. 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%.
Manganese sand filter material usage:
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 contained natural manganese dioxide can oxidation water second order iron and precipitation taken away, and make the water clean. Not only can be used for groundwater in addition to iron, and can be used for groundwater manganese removal; Our factory production of manganese sand filter material is made of high-quality natural manganese ore as raw material, the mechanical crushing multiple screening and become, appearance more than rough edges and corners, Browning, grain density, high hardness, corrosion resistance, less loss, long service life, in the water soak insoluble, filter the water containing manganese quantity does not increase, natural manganese sand can be the most difficult soluble in water purifying agent. Good in addition to iron and manganese removal performance, is the ground water and industrial water containing iron and manganese ion for iron removal and manganese removal processing the necessary products.
The current use of natural manganese sand deferrization principle has two kinds:
One kind is manganese sand surface is a layer of active filter membrane, can have very strong oxidation;
Another kind is manganese sand itself to iron catalytic, water ferrous iron catalytic into ferric iron, and make three order iron attached to the manganese sand particle surface, have in addition to the purpose of iron. Content 30% of natural manganese sand filter material, only suitable for the groundwater in addition to iron.
Manganese sand filter material physical index:
