  • Research of the performance of pulse electrohydrodynamics in blockage removal

    In line with contemporary trends and seeking to develop new methods and technologies, a new, original technology was explored and designed based on a non-conventional process of electrical pulse discharge in a water chamber, referred to as ‘Pulse Electrohydrodynamic Technology’ (PELHYDT). The application of the PELHYDT in sewer blockage removal is presented in this paper. Existing machinery can ...

  • Trouble Shooting for Trenchless Liner Installation During Sewer Line Rehabilitation

    ABSTRACTLining is being used by the utility industry as a cost effective solution to rehabilitate utility lines. Many types of liners, such as, cured-in-place-pipe (CIPP), fold and form PVC, deformed & reformed HDPE, etc., are being used to restore structural integrity of deteriorated pipes and to reduce inflow/infiltration. Most of the lining installation is carried out without any problem, ...

  • Modeling fats, oil and grease deposit formation and accumulation in sewer collection systems

    Fats, oil and grease (FOG) deposits in sewer systems are responsible for approximately 25% of all annual line blockages in the United States and lead to the release of 3–10 million gallons of untreated wastewater to the surrounding environment. Considerable effort has been made to maintain the conveyance of wastewater by cleaning pipes that have a significant FOG deposit accumulation. Changes ...

  • Pipeline Zooming for a Comprehensive Infrastructure Survey.

    Time, budget and resources often keep a municipality from maintaining comprehensive, up-to-date information on water and sewer pipeline conditions. Without a complete understanding of their infrastructures, municipal supervisors cannot properly prioritize and schedule maintenance activities. As a result, emergencies—backups, collapses, and overflows—happen unexpectedly, and must be dealt with on ...
