The ZMT operates a closed recirculation system for the maintenance of marine organisms. It consists of five independent circuits, with a total volume of more than five cubic meters. The water treatment system is modular and is comprised of a separator, mechanical filters, biofilters, protein skimmers, UV or ozone treatment and aeration.
The increased testing of biofilters (algae reactors, clams, mangrove plants) for use in water purification has been made possible through financial support from cooperating industry partners. More than 60 aquaria and three larger tanks are available for scientific trials with shrimps, fish and ornamental organisms.

Some circuits are remote-controlled by PC, which includes an automatic data storage and telephone alarm system. Physical parameters such as temperature, pH, salinity and oxygen content, and technical parameters such as flowrate, pumping cycles etc. are measured with sensors and logged continuously. Nutrients and other chemical parameters are also recorded. A small production unit for different algae and zooplankton species is also found on site for the production of live feed.
