Developing polymer-based membranes for aqueous nanofiltration and for solvent resistant to significantly extend the range of streams that can be treated with current membranes.
In this research, a self-cleaning photocatalytic membrane will be prepared to treat organic matters in groundwater. This photocatalytic membrane is based on a modified polymer membrane with TiO2 as the photocatalyst. Through modification, the UV resistance and oxidation resistance of the membrane will be improved, which will ensure that the photocatalytic membrane will not be damaged due to the UV and ROS during operation. Then, the ...
With the current, worldwide growth of industry comes an immense environmental impact. As the pharma, dairy and mining industry utilise a great deal of organic solvents and produce waste streams potentially containing harmful components, purification and separation is needed. Currently, these processes are done using energy-consuming techniques, often in combination with high temperatures. The use of membranes for solvent-resistant ...
Water scarcity is a pressing global issue affecting more than one-third of the global population, with human-induced water pollution, particularly from industrial effluents, exacerbating the problem. In this context, the employment of nanofiltration (NF) /membrane processes emerges as a highly promising and attractive technology with significant potential to mitigate the water crisis. Various fabrication techniques have been employed to ...
This project will characterize the performance of state-of-the-art polymeric membrane chemistries at enhanced pressure and temperatures for a selection of industrially relevant solvent classes. General structure-property relationships will be formulated to describe the behavior of the diverse membrane classes at these challenging conditions. This fundamental knowledge will allow both short-term implementation of solvent-resistant ...
Carbon dioxide emissions has resulted in alarming environmental issues, such as global warming, extreme weather, and species extinction. Membrane separation has a great potential to mitigate atmospheric CO2 concentrations. Membrane materials with high permeability, high selectivity and high stability are extremely desired. This project aims to fabricate novel 2D membranes by using nanosheets for efficient CO2 separation.
Nanofiltration (NF) membranes have garnered considerable attention in the domains of wastewater treatment and resource recovery due to their selective separation capabilities at the nanoscale. Nonetheless, challenges persist regarding their durability and practical applicability. This study commences with an exhaustive review of the current state of nanofiltration membrane technology, elucidating its advantages and constraints in wastewater ...
In many cases energy, water and resources contained in wastewater may have significant value if recovered. Therefore, the EU is currently confronted with a paradigm shift from wastewater treatment to resource recovery. To facilitate this shift, the SuPER-W European Joint Doctorate programme trains early-stage researchers (ESRs) in developing technologies for water, energy, nutrient and metal reuse, and bioproduction from (waste)water. The ...
Vitamin E is essential in many biological processes, such as in immune system functions and in protecting against cell damage.
However, vitamin E blood levels are below the desirable value for a large part of the global population. Therefore, vitamin E is often synthesized as an additive dietary supplement. In this production process, toluene is used during the work-up of alpha-tocopherol, which is the most biologically active form of ...
