The Hydro MicroScreen from Hydro International can serve as a replacement for primary clarification with a 90 percent smaller footprint and 50 percent less power usage. The rotating screen physically separates fine solids, with customizable removal rates up to 80 percent TSS, 60 percent BOD and 40 percent FOG from flow streams, reducing loading on downstream treatment processes, improving treatment capacity and efficiency, lowering operating costs, and increasing energy recovery in a very small footprint. 866/615-8130; www.hydro-int.com; Booth 3329.
