Safety & Service
For our projects, general safety and safeguarding processes are of paramount importance. During the design phase of a project, DMT carries out a risk assessment (HAZOP) and implements the results in the final design. Service is crucial and we provide it in accordance with our ISO 9001 certification. We are increasingly requested to provide integrated solutions, for example to combine biogas upgrading with waste water treatment.
Offering 24/7 support, our service concentrates on global technical support through secure internet connections for the installations we deliver. Our clients enter into tailor- made service contracts. In addition to service, a distinctive feature in the DMT quality chain is the co-operation with suppliers and partners. In the interest of our clients, we monitor the flawless and high-quality implementation of the projects agreed on and the service required.
DMT was founded in 1987 by Rob Dirkse
Trained as a chemist, Rob Dirkse worked in various technical fields. He was frequently
confronted with matters such as odour abatement and other environmental problems.
Due to new legislation at the end of the 80’s, a large environmental clean-up began. The
demand for ground water purification enabled DMT to excel. The bright solutions soon
gained a reputation in markets such as China, South-America and Europe. In 2001
founder Rob Dirkse retired and he was succeeded by his son Erwin Dirkse.
Today DMT Environmental Technolgy employs around 50 employees, has 20
international sales managers, maintains extensive relationships with knowledge
institutes, and provides 24/7 productions and services worldwide.
By sharing knowledge we enhance knowledge
DMT develops sustainable innovations. We are continuously looking for new and more innovative technologies, and in doing so we strive to achieve a unique position and cooperation with other knowledge partners. DMT has designed a specific membrane system for extracing CO2 from biogas. In order to share and further develop state-of- the-art technology, we and our specialised partners have realised the Accress pilot project in Lelystad.
