Department of Environmental Technology

The department is focused on development, application, and testing of various types of new (nano) materials in different environmental technologies to achieve their significant improvement.


We are dealing with nanofiber biomass carrier sand nanoparticles used for advanced wastewater treatment or application of zero-valent nanoiron for intensification of bioremediation processes. Part of our research is also subjected to membrane technologies, including membrane development and modification to mitigate biofouling and increase their crucial functionality (permeability).

In the scope of remediation of rock environment the laboratory focuses on the study of application of various remediation technologies (reduction, oxidation, biologica, physical), their combination and their optimized control (i.e. methods for the support of Fe (nano) particles using electrical current).

Research is conducted in close cooperation with industrial companies, other laboratories of the institute and other stakeholders.

Groundwater remediation
The technology of reductive de-chlorination of CIE using nanoiron is a verified in-situ remediation method used at a wide variety of locations. The support for remediation by DC brings verifiable increases in efficiency and reduces consumption nanoiron. This leads not only to accelerate remediation, but also to substantial cost savings. This method is protected by two patents: 304152 (“In situ maintenance method of rock environment contaminated with harmful chemical compounds”) and 306838 (“A method of in-situ remediation of a rock environment contaminated by harmful chemical compounds - dynamic control of DC electric field”), owners TUL and MEGA a.s.

Development of new types of reaction materials
based on a combination of different-types of zero-valent iron particles set directly on the specific conditions of individual sites can bring about further improvements in the technology. This research leads to new type of reactive material based on Fe particles, which is protected by patent: 306837 (owner TUL).

Development of carriers for wastewater treatment
This activity is focused on development, verification and application of innovative biomass carriers prepared specifically for final treatment steps (post-treatment) of municipal and industrial wastewaters. The carriers are designed as a composite material from micro and nano fibers.

Membrane technologies
One of the research activities is also subjected to membrane technologies, including membrane development and modification to mitigate biofouling and increase their crucial functionality (permeability).

Development of new types of materials on geopolymer base for storage/extraction of energy from rock environment. TUL is co-owner of patent: 306095 „Heat-conducting Material Based on Geopolymer“.

Development of equipment (EHGlogger) for the measurement and long range data transfer as a means of anti-flood protection.
