35%含量锰砂 NX天然锰砂滤料 除铁除锰用锰砂常年生产

锰砂简介

       锰砂滤料是采用优质天然锰矿石加工而成，外观呈黑褐色，主要成份是二氧化锰，含量在35-45之间。对于地下水除铁、除锰过滤有独特的效果。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。

      龙腾顺达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。它具有水处理滤料较理想的级配比例，使它在单位体积内有较大的比表面积、较强的截污能力、较大的氧化催化作用和较小的反冲洗流失率。

锰砂特点

       1、天然锰砂滤料的平均密度一般为3.2g/cm3至3.6g/cm3范围内。使用中对密度有特殊要求者除外。

       2、天然锰砂滤料的 可溶率不应大于3.5（百分率按质量计，下同）。

       3、天然锰砂滤料的破碎率和磨损率之和不应大于3。

       4、天然锰砂滤料应不含肉眼可见泥土、页岩和外来碎屑，含泥量不应大于2.5。

       5、滤料的水浸出液应不含对人体有毒、有害物质。

       锰砂的使用年限，对含铁浓度高的地下水一般为35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。

锰砂滤料应用

      锰砂主要用于降低水中的铁和锰总含量，（注：MnO235％既可除铁，又能除锰，MnO230％）只能用于地下水除铁）锰砂滤料主要用于降低水中的铁铁和锰总含量。锰砂滤料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，矿泉水、纯净水、离子水生产线的预处理除铁锰沉淀，以及地热工程和泳池工程的前期水处理除铁除锰等。应用领域：矿泉水、纯净水、离子水生产线的预处理除铁锰沉淀，以及地热工程和泳池工程的前期水处理除铁除锰等。

Introduction of manganese sand

Manganese sand filter is made from the high quality natural manganese ore, which is black and brown, the main component is manganese dioxide, and the content is between 35 and 45. It has a unique effect on the removal of iron and manganese. Natural manganese sand is a kind of strong oxidant, oxidation of ferrous iron in water, iron and manganese removal filter device used in drinking water, groundwater used to purify the water quality in addition to iron and manganese.

Longteng shunda manganese sand filter materials are using high quality domestic manganese sand, grain density, mechanical strength, strong chemical activity, not easily broken, insoluble in water, natural manganese ores. It is used to sanding the processes of miscellaneous, broken, dry, magnetic, sieve and dusting. The processed manganese sand is adjusted by a certain level. It has a water treatment filter material ideal grading scale, making it in unit volume larger specific surface area, strong ability of sewage, the catalytic oxidation of larger and smaller backwash turnover rate.

Characteristics of manganese sand

The average density of natural manganese material is 3.2 g/cm3 to 3.6 g/cm3. Except for the special requirement for density in use.

The soluble rate of hydrochloric acid in the natural manganese sands shall not be greater than 3.5 (the percentage rate is the same as the mass meter).

The combined rate of breakage and wear rate of natural manganese sands shall not be greater than 3.

The natural manganese sand filter should not be visible to the naked eye, shale and foreign debris, and the amount of mud should not be greater than 2.5.

The liquid of the filter shall not contain poisonous and harmful substances to the human body.

The use of manganese sand, for example, has been used for three to five years, and has been used for more than ten years for underground water with low iron concentration. In some natural manganese sand filter, filter layer of the upper manganese sand will gradually form spherical sand "rust", "sand" rust surface with a layer of "active filter membrane", still have contact with catalytic iron ability, therefore, form the "iron ore", is not a sign of natural manganese sand failure. It is necessary to change some of the filter material when the rust is grown and the filter size is too thick to affect the effect of iron. So, in our construction process should pay attention to whether there is the existence of the rust sand ", if any, must distinguish clearly the size of the sand "rust", if it is a small specifications, can continue to use, can reduce the cost of our industry, if it is a large specification, is about to change, so as not to affect filtered water quality.

Manganese sand filter application

Manganese ore is mainly used for reducing the total content of iron and manganese in the water, (note: MnO2 35 or higher is in addition to iron, and manganese removal, MnO2 30 or less) can only be used for groundwater in addition to iron) manganese sand filter material is mainly used for reducing the total iron iron and manganese content in the water. Manganese sand filter materials used in the iron and manganese removal of domestic and drinking water filter device, the filtering effect is very good, mineral water, pure water, rinse the pretreatment of the production line in addition to iron and manganese precipitation, and geothermal engineering and swimming pool in the early period of the project such as water treatment in addition to iron and manganese. Areas of application: mineral water, pure water, rinse the pretreatment of the production line in addition to iron and manganese precipitation, and geothermal engineering and swimming pool in the early period of the project such as water treatment in addition to iron and manganese.
