The Strensham Water Treatment Plant, in the United Kingdom, purchased a bubble barrier in order to prevent system contamination by oil, leaves, and animals from the River Severn, the plant's raw water source. This low maintenance solution works by forcing compressed air out of carefully sized and positioned nozzles below the water's surface. This causes water and air to be carried to the surface. A flowing current of air and water with less relative density than the surrounding water is created, forming a subsurface barrier.
