Project summary

In contrast to the majority of toxic materials, applied in modern engineering, where for safe operation it is enough to follow usual safety engineering rules, beryllium is dangerous at any stage of its production and application. Experience of industrial countries in usage of beryllium and its compounds (RF, USA, Germany, Japan), where hundreds of berylliosis diseases have been registered, testifies that the problem of protection from beryllium is actual all over the world.

By joint efforts of specialists in chemical engineering and ecology at present there have been worked out effective legal regulations and safety rules; they helped to decrease but not to eliminate the danger of affection by beryllium.

The present Project has as its object, on the base of experience accumulated in Russia in handling with beryllium and its wastes, to work out methods of work that would exclude both beryllium occupational diseases and contamination of environment with beryllium.

It has been planned:


- To work out the flow-sheet for purification of wastewaters of the beryllium production providing for possibility of secondary usage of water (water circulation).
- To work out methods of utilization of metallic wastes and slags providing for regeneration of beryllium contained in the above mentioned products to maintain secondary usage of beryllium.
- To work out methods of rendering harmless solid combustible beryllium wastes and oils with the aim of regeneration of beryllium out of these products and to maintain secondary usage of beryllium.
- To render harmless solid incombustible beryllium-containing production wastes (conversion of beryllium into biologically inactive state) for their safe burial. At work it is intended:
- To carry out mutual consultations with foreign specialists and co-workers in order to exchange of opinions.
- To check up technical decisions on the usage of beryllium-containing wastes applied by foreign companies and institutions.
- To familiarize foreign specialists with operation of model apparatus and test stand installations.
- To issue information sheets in order to reflect the achieved work results.
- To realize hygienically well-founded choice of optimal variants for treatment of beryllium-containing wastes and conditions of their burial providing for exclusion of danger of negative influence upon personnel working conditions and upon ecology of the industrial plant and burial grounds placings.

After the completion of the present Project it is proposed to carry out cooperation with foreign researchers and engineers in the following directions:


- Working out and learning to handle new industrial typical technology for treatment and utilization of beryllium wastes.
- Creation of proving grounds intended for testing the solid waste burial methods.
- Working out new materials for catching microquantities of beryllium in solid and liquid media.
- Working out and design of the industrial monitoring schemes.
