Overview

Experimental study enhances water discharge and soil strength in dredged sludge, suggesting efficient treatment methods.

Key Points

  • This research investigates the effectiveness of an alternating vacuum and electroosmosis method for treating dredged sludges.
  • Conducted laboratory experiments using a vacuum–electroosmosis alternating test device.
  • Monitored performance indicators including water discharge, surface settlement, and electric current during tests.
  • Evaluated soil properties such as shear strength and moisture content post-treatment.
  • Alternating vacuum–electroosmosis improved water discharge by 46.1%.
  • Final moisture content was reduced by 20.8%.
  • Shear strength increased by 35.6% compared to synchronous application.
