Working for our environment

Since the new millennium ROCtecs engineering has concentrated its work on a sustainable development for waste water treatment and biogas fermentation.

As a medium sized and independent engineering business ROCtecs has one of the most advanced biological processes brought to practice. Together with various scientists ROCtecs has developed innovative and complex equipment and operation improvement to reduce the operation costs of biological processes by

30% - 50%.

Within the last ten years ROCtecs has implemented the process technology in more than ten waste water treatment plants and has managed to consistently meet the needs of our customers.
