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.
