The core technology of the DesiUS is the BioPush flowthrough cell, which due to its highperformance surface converter generates a homogeneous cavitation field within the reactor. The energy efficiency and the impact on the sludge is ignificantly higher than with traditional ultrasound technology. DesiUS – High standards in efficiency and durability Thus problematic substrates, such as highly thickened mixed sludge of municipal water treatment plants can be treated efficiently.
