BOKELA‘s corporate concept is based on three pillars: the comprehensive process and industry-specific know-how, the practical experience that BOKELA gathers around the world and the passion of the BOKELA team when it comes to master new challenges. Every project, every solution developed by BOKELA engineers, focuses on the entrepreneurial added value as well as on increasing the competitiveness of the respective customer.

We question the requirements and wishes of our customers until we understand them. This way, can we develop solutions with the desired result and build filter systems which succeed in every aspect. The cost-effectiveness of BOKELA solutions becomes particularly clear if the entire life-cycle costs of a filter system are taken into account.



The BOKELA engineers understand the physics of flow processes and suspensions down to the last detail. They are ambitious, creative and are never satisfied with the first idea that comes to mind. Developing systems for innovative process filtration means looking closely, analyzing exactly, finding creative solutions and adapting them to new situations. This creates depth of knowledge and flexibility in order to continuously set new impulses - in the process engineering conception and in the construction of efficient filter systems.

Our customers benefit from our ingenuity and long-term economic and ecological benefits of BOKELA filter technologies.

What I love about BOKELA

„What really makes a difference for me, personally, is our teamwork. Our cohesion and team spirit not only helps each individual, but also constantly advances our technologies.“

Whether in miniature size or as house-sized constructions - BOKELA filter systems are individually designed and constructed according to the respective customer requirements. The ideal manufacturing location for the filter systems depends on their size, complexity and logistical challenges. From Australia through Russia to North or South America, the technical, logistical and cultural challenges involved in the construction of the filter systems are conceivably different.

That is why we have built up an international network of selected manufacturing partners, with whom we maintain a trusting and proven cooperation for many years.

They are certified by BOKELA and able to manufacture our filtration equipment to our high quality standards. This allows us to manufacture as many components as possible near the site, often reducing transport costs and adhering to specific national manufacturing regulations. Core components are manufactured in Central Europe, especially in Germany. The experience and know-how of our engineers ensures the high quality in all stages of the planning and production process.



DIN EN ISO 9001: 2015 is the certification with which BOKELA has had the quality of its processes and processes checked since 1996. The certification is carried out annually by an independent auditor and gives our customers the certainty of permanently benefiting from BOKELA's high quality awareness and comprehensive quality management.



Start-up! On December 15, 1986 the time was ripe and an idea became reality. Dr. Reinhard Bott, Dr. Robert Kern and Dr. Thomas Langeloh founded BOKELA as a start-up company directly from the University of Karlsruhe - today's KIT. BOKELA already took on a pioneering role in the start-up phase, as company foundations deriving directly from universities were a real rarity at the time in Germany.

In the early years, the company's activities focused on services such as technology transfer for large companies, contract development, consulting and optimization of separation equipment. Even back then, BOKELA was already internationally oriented. In particular, projects for the optimization of filter systems led the BOKELA engineers around the world.

 As part of such projects, BOKELA has optimized filter systems from other manufacturers on behalf of customers. This engineering performance allows a deep insight into operating problems and bottlenecks of conventional technologies, constantly calls for innovation and makes it possible to realize new ideas in the short term. The solutions developed are always crystallization points for new ideas and innovations. These innovations are reflected in our own BoVac, BoHiBar and BoCross filtration technologies, which were launched beginning in the mid-1990s.

Today, BOKELA is one of the top addresses when extraordinary tasks for solid / liquid separation have to be mastered in a production process or particularly high-performance filtration technologies are required.
