The working principle of the iron and manganese removal device: It uses an oxidation method to convert low-valent iron ions and low-valent manganese ions in water into high-valent iron ions and high-valent manganese ions, which are then removed through adsorption and filtration, achieving the goal of reducing the iron and manganese content in water. The filter media used are refined quartz sand or manganese sand.

    　Many underground water sources contain fluoride, and the concentration often exceeds national standards. If left untreated, such water cannot be used as drinking water, as long-term consumption of water with high fluoride content can lead to fluorosis, affecting physical health. Mild cases may cause teeth to turn black, enamel spotting, enamel detachment, and premature tooth loss, while severe cases can lead to bone sclerosis and even skeletal deformities.
    　Therefore, to protect public health and the environment, our company has carefully developed and produced a fluoride removal device. This device ensures that the treated water meets China's drinking water standard for fluoride content, which is less than 1mg/l. Additionally, industrial wastewater treated with this device can also meet the discharge standards for industrial waste.
