Deferrizers and demaganizers are series of products designed by our company for underground water with comparatively high iron and managanese content according to aerating oxidation priciple . in these prducts , packed natural manganese sand in filter is applied as filtering materials , and oxygen in air is applied as oxidants , to make ferrous iron in water oxidized into ferric iron , in a same time , oxidation reaction makes its produced its produced substances left in filtering materials for purposes of deferrization and deman - ganization 除铁锰装置是我公司针对铁、锰较高的地下水，按曝气氧化法的原理而设计的系列产品，它是利用过滤器内装填城然锰砂为滤料，利用空气中的氧化剂，使水中的二价铁，同时发生氧化反应使其物进截留在滤料中，从而达到除，除锰的目的。
