HYDROTRANSPORT 13

13th International Conference on Slurry Handling and Pipeline Transport

Johannesburg, South Africa 3-5 September 1996

The Conference Proceedings can be purchased from: Mrs Marian Rolfe. For information about further conferences in this series, please check our Events List or contact Babs Astle at BHR Group.

Introduction

In 1996, BHR Group's Conferences section organised the 13th International Conference on Hydrotransport. Hydrotransport, the handling of solid/liquid mixtures, is a process used throughout industry. It provides a cost-effective, economic and efficient method of slurry transmission with the minimum of maintenance problems and a low impact on the surrounding environment. The technique has been successfully employed in a wide variety of situations from hygienic movement and processing of food and pharmaceutical products, through chemicals, oil, mining and construction applications, to the secure transportation of effluent and waste products.

This Conference has been, for over 25 years, the premier international event in Hydrotransport, bringing together experts and users from all parts of the world and from many diverse industries. The Conference will be held again in 1999, and more details will be available on this web page nearer the time.

For more information on future conferences please see our list of future events.
