Our company offers "Manganese Sand," which is a special coating of oxidants such as manganese dioxide on the surface of filter sand. It is a filtration material used for the removal of iron and manganese from raw water that has chlorine injected into it, using manganese sand as a catalyst to oxidize and remove manganese from the raw water. Furthermore, as long as chlorine is present in the raw water (0.7 mg/L or more is desirable), the contact oxidation power remains unchanged. 【Water Quality Standards】 ■ Iron: 0.3 mg/L or less ■ Manganese: 0.05 mg/L or less *For more details, please download the PDF or feel free to contact us.
