Ozone oxidation is more and ...

Ozone oxidation is more and more widely used in drinking water treatment. However, when bromide ions are contained in the water, bromate, a by-product harmful to the human body, is produced. The methods for removing bromate include adding activated carbon, ferrous ions, zero-valent iron and ultraviolet radiation. Among them, there are many researches on activated carbon, but after a period of time, the efficiency of removing bromate by activated carbon decreases, and it needs frequent regeneration and replacement, which will inevitably increase the cost of drinking water treatment.
UV irradiation has a high energy consumption and high processing costs. Zero-valent iron, especially nano-zero-valent iron or iron-based composite filter media, has a rapid removal rate of bromate, and is a promising removal technology, but it is affected by factors such as DO and ions in water. . Therefore, it is still necessary to further study the existing removal technology in order to seek practical application of bromate removal technology.

so , i think the UV and  iron powder you can try .

i hope these can help you .
