Floating debris can cause considerable damage to water management systems, e.g., hydropower plants, seawater desalination plants, or locks. A compressed air floating debris barrier is an efficient barrier for any floating debris. It creates a current on the water surface in two opposite directions. This current holds back everything that floats on the water. Watercraft are not affected. You can pass the compressed air floating debris barrier unhindered. Movable components such as lock gates can thus be optimally protected from floating debris.
