Engineering services

Our "long Years Experiences" in plant design, especially in the field of environmental- and process engineering, is the basis for finding optimal solution concepts. Tethys ENOTEC GmbH delivers mainly water- and sewage treatment systems (also in compact /skid forms) for land and marine applications. In the maritime application, one of the most customer wishes is one skid solution plants. This type of systems are tested units, ready for operation and can be installed in a short time and they are easy to integrate in the existing systems. According to the present IMO Resolutions (International Maritime Organization) and the possible changed rules, it is necessary to adopt the type approved systems on the newest IMO Resolution. In the offshore technology, water- and sewage treatment plants have to be match to the special requirements on platforms. In case of retrofit actions, it is necessary to design the systems so, that an easy integration under running conditions, is possible. These all be realized in our company by our knowledgeable experts, which have a long experience in design, scale up and manufacturing such a systems, also for the other companies.

Services and other Equipment / Deliveries

  •   General Engineering
  •   Plant Design 
  •   Design, developing and realizing the concept and necessary test procedures
