The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...

Sludge Dewatering in Freezing Beds
This paper summarizes the results of laboratory and pilot scale studies on the development of the sludge freezing bed. Laboratory studies indicated that a freezing bed could dewater up...

Pumping In and Pumping Out: Case Histories of Fluidized Sand Bypassing for Channels and Beachface Dewatering for Beaches
New technologies can change management of sand in coastal areas. Fluidization, pumping in additional water beyond the quicksand point, makes a 50:50 sand-water slurry that will flow down...

Evaluation of Sludge Screening and Screenings Dewatering Technologies
The concept of digested sludge screening has been utilized at the City of Los Angeles' Hyperion Treatment Plant to remove extraneous objects, hair, and fibrous material in...

A Case Study in Sludge Handling
When the Wyoming Valley Sanitary Authority (WVSA) converted its operation to a secondary treatment plant in 1988, something important was missing. That something was a method to handle...

Dewatering Using a Floating Bulkhead Proves Flexible, Reusable and Cost Effective
Going beyond a traditional bulkhead dropped in place with a barge crane or crane hoist, a steel floating bulkhead was conceived to dewater powerplant intakes, gated spillway bays or outlet...
