DEWATERING AND VOLUME REDUCTION OF SOIL WITH HIGH WATER CONTENT USING VACUUM DEWATERING METHOD WITH GEOTEXTILE TUBE (Part 3)

Dewatering Fly Ash Slurries Using Geotextile Containers

The design of geotextile containers for dewatering applications typically requires good retention of the confined fill material solids. This becomes difficult to achieve when the fill material is fine grained and the pore openings are large. Furthermore, the proper retention becomes critical if the confined material is contaminated. Fly ash is one of the fine-grained geomaterials that exhibit b...

Strategies for High Vacuum Dewatering on Paper Machines

The Paper machine vacuum system is an important operation for dewatering of wet web to increase percentage solids in web. There are various models available to assess the influence of vacuum on the above parameters. In this present investigation the steady state model is discussed for estimating optimum vacuum load in flat boxes of Fourdrinier paper machine as the flat boxes are the main compon...

Innovative Algae Dewatering Technology

Abstract This paper describes a novel technology for dewatering of bio materials, such as algae, for biofuel production and other applications. This hydrodynamic separation (HDS) technology uses customized fluid flow patterns to focus suspended particulates into a well-defined band near a side wall of a curved channel, and where they can be separated off with a suitably designed flow splitter. ...

Sludge Dewatering by Impulse Drying

An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...
