Investigation of aviation's contribution to tropospheric NOx-O3 presence

As global air traffic has continued to grow overthe past two decades, it has...

Removal efficiency of antibiotic resistance using the O3STEP-filter

As antibiotics now save millions of human and animal lives annually, the World Health Organisation (WHO, 2019) declared Antibiotic Resistance (AR) as the number five most dangerous risk to global health. Several researchers mention WWTPs to be an important source for AR as the growth of bacteria is stimulated in an environment with a selective...

Ozone-Based Regeneration of Granular Zeolites Loaded with Organic Micropollutants

The removal of organic micropollutants (OMPs) in the aquatic environment is crucial to avoid health hazards. Zeolites have been confirmed as a selective adsorbent and can effectively remove target OMPs. To achieve sustainable application of adsorbents, regeneration of zeolites is required. <br/>The objective of this study was to investigate the...

On-site Regeneration of Acetaminophen Loaded Zeolite Granules by Applying Gaseous Ozone Based Oxidation Process

The wide application of pesticides, pharmaceuticals and personal care products cause an increasing contamination of aquatic systems. Adsorption by zeolites is a promising process to remove target organic micro-pollutants (OMPs) selectively from water bodies. In order to have a sustainable adsorption process, restoring the adsorption capacity of...

Assessing the correlation of aviation nitrogen oxides and ozone with respect to specific weather patterns

Aviation is a large contributor to anthropogenic climate change through its emissions, particularly through nitrogen oxides (NOx), which reacts to Ozone in the atmosphere. Due to the emission of NOx, the ozone budget of the atmosphere is disturbed which results in an increase in the Earth’s surface temperature. To mitigate this effect, the...

The Freshwater Factory: removing organic micro-pollutants with ozonation

Removing organic micro-pollutants (OMPs) can enable wastewater reuse to alleviate pressure on fresh water sources. This research aims on the prediction of OMP removal efficiencies by ozonation and biofiltration based on experimental data sets and/or modelling. Comparison of experimental data on average OMP removal of three different studies from...

Organic Micropollutant Treatment by Pre-Ozonation and Activated Carbon

Inadequate treatment of wastewater effluent is one of the major point sources of pollution of organic micropollutants (OMPs) into aquatic environments. Wastewater treatment plants need to be upgraded to reduce OMP contamination. Recently, the combination of pre-ozonation and granular activated carbon (GAC) filtration has been proposed as a...

Fire safety engineering of high rise timber buildings

During this MSc thesis it has been carried out an extensive literature review on fire safety engineering, on timber behaviour on fire and on fire safety regulations in different countries. A preliminary design for a high rise cross laminated timber building (CLT) has been carried out in order to obtain a minimum thickness of the structural...
