Workshop on Alumina production

Reinhard Bott,
FiltraVision GmbH, Germany


Lecture «State of the art filtration equipment and practices for alumina production»


Dr. Reinhard Bott studied at University "Fridericiana"Karlsruhe“ on Chemical engineering in 1980. Then he worked as a senior assistant of Professor Dr. W.H. Stahl at Institute for Mechanical Process Technology and Mechanics. In 1985 he finalized PhD-thesis "About Continuous Pressure Filtration”. In 1986 he established of BOKELA by Reinhard Bott & Thomas Langeloh et al. as a start up company.

The company engages in development, installation design processes for continuous vacuum and pressure filter plants (like big dimeter "Boozer" disc filter, various drum filter types, pan filter, high pressure squeezing filter presses WAP, HiBar Oyster filters, HiBar Steam Pressure Filtration) but also most moderndynamic cross flow filters (DYNO Filter) for absolute membrane filtration, sieving filtration and precoat Filtration.

Another part of activity is marketing of the revamping concept for the modernization of running filter plants in various markets and for any kind of cake forming filtration for the sustainable improvement of performance.

The major strategy of the company is setting up of an international, modern concept (international sourcing and strategical partnering) for manufacturing and component supply, consortial project executions with international partners.

In 2014 Dr. Bott transferred of the ownership of BOKELA to the Japanese technology group TSK, Tokyo.
