Introduction

Are you involved in Transporting Solid/Liquid Mixtures in a pipe?

Do you deal with Slurries or Sludges or Slimes or Sediments or Compacted Solids or Suspended Solids?

The challenges of handling solid/liquid mixtures in pipelines, in open channels, in long distance pipeline transport and in-plant transferences occur throughout industry. These processes provide cost-effective, economic and efficient methods of transporting products with the minimum of maintenance and low environmental impact.

An understanding of how to optimise handling techniques; how different industries have solved complex problems; trouble shooting - all demand an understanding of the techniques required and the deployment of different engineering solutions.

For almost 30 years, this Conference has been the premier international event bringing together experts and users from all parts of the world and from many diverse industries. The opportunities to discuss new research and developments, to consider innovative new solutions and to explore technology transfer between industries makes this event essential for all engineers concerned with any aspect of slurry transportation.
