Within this tank, the stormwater will first enter an equalization area, and then find its way through stacked coalescing/settling media packs to move onward to the tank’s outlets. What eventually comes out of this clarification tank is a highly clarified stormwater flow that will greatly reduce the amount of solids. In addition, as the incoming flow goes up, the water level within the clarification surge tank will rise up accordingly – gradually increasing its supply of stormwater to the biofilters due to increased head. This will maximize the biofilters’ throughput capacity while reducing the filter maintenance.
