Some Considerations for Designing an Air Burst System

Air Burst System

Air burst systems are a standard requirement for municipalities and industries that draw water from rivers, lakes or ponds. The air burst system is designed to keep intake screens below the water level clear of debris and silt which accumulate as a result of inward water flow. The basic principle is to displace these materials with a high volume blast of compressed air in reverse flow direction through the screens. The systems are normally designed to be automatic and operate on a timed basis, calling for an air burst usually once or twice a day, or as required/established, depending upon the intake water conditions. Some basic calculations must be made to determine the volume of air required (relative to the screen size), air storage receiver size, and piping and air burst valve size based on air volume and distance from valve to screen. A good control design will allow the … Read the rest
