Prevention of pollution due to stormwater flow is the new challenge in water pollution control. With a view to avoid heavy investments in buffering capacity, a new process called Actiflo® has been developed. This process allows an upflow velocity of 130 m/h over the lamella, which means a total area of only 0.03 m2 per m3/h of influent capacity. Under these conditions, a reduction of 80% of the TSS is achieved using about 60g/m3 of ferric chloride and 0.8 g/m3 of polyelectrolyte. High compactness and quick start up of the process allows one to set up the Actiflo® in any place where prevention of stormwater flow is suitable, with low operating and investment costs compared to conventional solutions.
