Manganese sand filter, manganese sand water

Produced by manganese sand filter is mainly used for water iron and manganese removal filter, the product is made of natural manganese ore as raw material, processed into different content filter manganese sand filter. The appearance of spherical, sharp and strong, brown, has a good addition to iron, manganese performance. Manganese manganese sand filter manganese dioxide mainly based, the user can deal with different purposes, the choice of different levels of products to MnO2 content of not less than 30% of manganese and manganese sand filter either, and can in addition iron, if more requirements, can be 60% MnO2 content filter, long service life, in the process without the use of any drug dosing, the treated water meet the national drinking water quality standards, performance standards for the cities and towns of the Company water treatment industry with natural manganese sand filter standard CJ / T3041-1995? Product Specifications Analysis Project Test Data Analysis Project Test Data manganese content of 15-50% wear rate ≤1.0% Density 3.4 g / cm3 density crushing rate ≤1.0% 2.0 g / cm3 clay content ≤3.0% iron and manganese filter requirements:? First, sufficient mechanical strength, sufficient chemical stability, non-toxic substances, in addition to iron water quality without adverse effects. Second, having iron and manganese have a greater adsorption capacity and shorter, "maturity." ? Removing iron: aeration oxidation, oxidation and exposure to chlorine oxidation filtration as much. ? Manganese removal method: potassium permanganate oxidation, filtration and chlorine contact with biological fixing and removal method. ? Effect of removing iron and manganese major factors: 1, iron and manganese interfere with each other in the process. 2. Effect of silicic acid dissolved in water. 3, alkalinity, PH value. 4, the impact of organic matter in water.
