Pipe Unplugging by Fluid Wave-Action
Category: Waste Management > Waste Treatment > Pipe Unplugging
Reference # : Model No :
AEAT technology is based on a fluid wave-action principle, which operates much like ocean wave-action on beach erosion, possibly aided by use of a solvent, coupled with positive and negative pressure pulses that tend to loosen the blockage. It can operate on a long pipeline that has drained down below a blockage. The system consists of a water/solvent tank, pressurize/vacuum vessel, fluidic control unit, vacuum finishing pump, and an air-operated jet pump eductor
• Short mobilization and demobilization times possible with an adaptive jumper.
• Can be used to deliver chemical solvent to the blockage where a solvent may be of assistance in loosening a blockage.
• Can be applied to the section of the pipeline that has drained down below the elevation of the blockage.
• System works under relatively low drive pressures (100 psi tested).
• Technology can negotiate many elbows. (Unlike mechanical devices, this method is unaffected by elbows in the pipeline.)
• Technology can be operated remotely.
• No water discharged until the blockage is cleared, therefore minimizing the amount of liquid added.
• Location of the blockage can be determined by the amount of water required to back-fill the pipeline.
• Length of reach in an empty pipeline is limited by the strength of the vacuum pump.
• Positive and negative pressure cycles acting to loosen a blockage were effective for most blockage types; however, unplugging time is relatively high as compared to other methods when considered without the effect of vacuum and pressure cycles.
• Although the technology achieved its primary goals for the demonstration, the technology is still in its infancy and needs further development.
