Anglian Water uses ozone and hydrogen peroxide to oxidize difficult organics including Metaldehyde while reducing bromate formation to less than 5mg/L

Challenge 

Anglian Water in the UK is challenged by a potable raw water supply that has occurrences of pesticides.

Solution

An innovative reactor design developed by Xylem called Pro3mix. Pro3mix uses ozone and hydrogen peroxide to oxidize difficult organics while reducing bromate formation.

Benefit

PRO3MIX is capable to remove up to 80% of the Metaldehyde whilst simultaneously controlling Bromate formation to below 5μg/L. It was demonstrated that compared with other AOP processes PRO3MIX can provide the lowest operational costs.
