New concepts for efficient immobilization of enzymes in inorganic membrane reactors (Cerenzyme)
Involved DTU departments: DTU Energy, DTU Chemical Engineering
External partners in the project: EMPA (CH), Iowa State University (US)
Funding body: DFF – Danish Council for independent research
The low industrial use of enzyme membrane reactors is due to the need for replacing the membrane frequently (as properties decay with use), and the low enzyme loading capacity of the commercial polymer membranes. Materials science and enzyme technology have been rarely considered together for targeted enzyme immobilization. This project proposes, for the first time, that the selection and processing of the membrane material are tailored considering the enzymes needs. The objective is to design optimal membrane systems for efficient immobilization of enzymes on inorganic membranes, as well as identifying generic aspects of interaction between inorganic surfaces and enzymatic proteins. The project addresses the development of such immobilized enzyme systems for cascade conversion of CO2 to methanol, and for one-step enzymatic isomerization of glucose to fructose. This information should allow the creation of a novel technology that could be applied to most enzyme production processes.

Smart cities water solutions
Involved DTU departments: DTU Environment, DTU Compute
External partners in the project: DHI, Aarhus Water, Smith Innovation
Funding body: Realdania
This innovation project aims to develop software solutions for dynamic control of pumps and gates in sewer systems to minimize the risk of combined sewer overflows and flooding by storing and discharging excess water volumes in the least harmful manner possible.

Ceramic, high-flux microfiltration membrane
Water DTU departments: DTU Energy, DTU Nanotech
External partner in the project: LiqTech International A/S
Funding: MUDP
The collaboration between DTU Energy and LiqTech International A/S aims to master ceramic processing procedures for producing optimized SiC membranes for micro- and ultrafiltration. In the first phase, the research activities will focus on understanding how single steps in ceramic processing and different processing parameters affect the membrane microstructure. The output will be a demonstration membrane to be tested by potential customers. The second phase aims to gain deeper understanding on the membranes characteristics, finding correlations between their surface properties, microstructure and separation performances.
