Ozonation can be applied to mitigate the discharge of organic micropollutants from municipal wastewater treatment plants (WWTPs) to the aquatic environment. The toxicity of metals also present in WWTP effluents strongly depends on their speciation. Therefo ...
We successfully demonstrate the in situ formation by X-ray irradiation induced polymerization of a three-dimensional (3D) hydrogel based on poly(ethylene glycol) (PEG) diacrylate (PEG DA), with the option of heparin incorporation to enhance cell adhesion. ...
In this work, solar disinfection of wastewater was studied, focusing on the effect of selected environmental variables, namely light intensity, continuous/intermittent light delivery, and post-irradiation storage as well as dilution in lake water. These va ...
Water quality and bacterial infections are directly related to human health and wellbeing, thus waste water treatment is a necessary procedure for avoiding disturbances to ecosystems and for assuring human health. Furthermore, bacterial contamination in wa ...
A pilot-scale hospital wastewater treatment plant consisting of a primary clarifier, membrane bioreactor, and five post-treatment technologies including ozone (O-3), O-3/H2O2, powdered activated carbon (PAC), and low pressure UV light with and without TiO2 ...
Disposable cylindrical shaken bioreactors using plastic bags or vessels represent a promising alternative to stainless steel bioreactors, because they are flexible, cost-effective and can be pre-sterilized. Unlike conventional well-established steel biorea ...
Fibres made from carbon nanotubes (CNTs) have not yet achieved strengths approaching that of individual CNTs. The problem is that load is not effectively transferred between the constituent, discontinuous CNTs. High energy irradiation has shown promise on ...
The abatement of 9 polychloro-1,3-butadienes (CBDs) in aqueous solution by ozone, UV-C(254 nm) photolysis, and the corresponding advanced oxidation processes (AOPs) (i.e., O-3/H2O2 and UV/H2O2) was investigated. The following parameters were determined for ...
In this study, simulated solar disinfection of secondary effluent was followed by dark storage at different temperatures or different receiving water matrices. Escherichia coli illumination was followed by 3-day monitoring of the bacterial population and i ...
Bromide measurements and mass balances in the catchments of major Swiss rivers revealed that chemical industry and municipal waste incinerators are the most important bromide sources and account for similar to 50% and similar to 20%, respectively, of the s ...
