For us, plant construction is the precise intermeshing of process engineering know-how, sound planning and structured project management. Tried and tested installation teams, our own commissioning engineers with expert knowledge, who train your employees and familiarise them with the plant, are elementary components of our philosophy. We will not leave you alone even after the project has been completed. We stay in touch via service and maintenance and help you quickly and unbureaucratically in your day-to-day operations.

Whether in modular design, as a container plant or as an individually designed complete plant, we will meet your requirements and combine the most diverse technologies to create a functioning treatment plant. We regard necessary certifications such as the German WHG as a matter of course.
