Air Scouring
Air scouring is a particular form of abrasive cleaning that works by using filtered compressed air, injected into the mains via hydrant or air insertion point to propel a small volume of water at a high velocity.
When the valve upstream of the air entry point is opened slightly, the filtered compressed air mixing with water creates a vortex that travels through the isolated section removing sediments, bacteriological slimes or biofilm and soft mineral scale through a scour point at the other end of the pipe. Once water exiting the pipeline is clear, cleaning is complete and the water supply is restored to the pipe section.
