• The Corpus of Contemporary American English prefers master's thesis (212 to 6). prefers master's thesis (384 to 82). Sorry, no direct query links here, since the site uses iframes and I'm too lazy to dig the URLs out. Search master 's thesis (note the space before the apostrophe) and master thesis. This one is a nice corpus because it breaks usages up by country. prefers master's thesis 23 to 0 (same search guidelines as above).

I also searched many an exclusively British corpus, but without yielding any meaningful results.

The relevant ELU question that choster linked discusses master's degree, which has the same form as master's thesis. The question is about apostrophe usage, but note that nobody suggested it should be master degree.

Grammatically speaking, master's thesis unequivocally means a thesis of a master. Master thesis can be read the same way, but also as primary, principle or main thesis.

Aerobic granular sludge (AGS) systems represent a relevant alternative to conventional activated sludge systems and a range of AGS models were developed to better understand those systems (Baeten et al., 2019

Mass-transfer in AGS systems is limited by diffusion, resulting in the formation of concentration gradients of electron donors/final acceptors within the granules. During the aerated phase, an oxygen gradient thus develops within the granules, whereby the outer layers are aerobic and the inner core is anoxic or anaerobic (de Kreuk et al., 2007). The formation of different redox conditions within the granules allow nitrification and denitrification to occurs simultaneously during the aerated phase (Winkler et al., 2013), and nowadays, it is well accepted that simultaneous nitrification and denitrification (SND) is a key feature of AGS. But practical experience however indicates that SND is limited during the treatment of municipal WW with AGS systems due to: Read more. (PDF, 252 KB)

Aerobic granular sludge (AGS) systems have been developed over the past 20 years and now offer a relevant alternative over conventional activated sludge systems. Advantages of AGS include enhanced settling properties, a high suspended solid concentration and the co-existence of different redox conditions across the granules, which result in significant energy, footprint and chemical savings (Khan et al., 2015).

The wastewater treatment plant (WWTP) of the future is possibly a net source of energy and valuable products. The development of CO2-neutral WWTPs requires both improving the recovery of internal wastewater energy resources and reducing energy demand as well as greenhouse gases emissions (Larsen, 2015).

One way to reach the sustainable development goals is to reduce the consumption of natural resources. In the water sector, this has triggered increased interest in circular and resource-oriented approaches to urban wastewater management. Examples of resource-oriented approaches include the recovery of nutrients for food production, the production of biochar or biogas as alternative energy sources, the recycling of grey- and rainwater to be used for green and blue urban infrastructure to enhance biodiversity, recreation areas, or heat management.

In Urban Drainage planning, local rain data are often available at too low temporal resolution and with a too short time span to allow for robust statistical estimates of sewer network failures with a return period of 10 years by means of long term simulations. Because of this reason, single historical design storms are still frequently used instead.
Alternatively, the precipitation depth associated with a certain return period and duration can be estimated by empirical formulae and transformed into events with high temporal resolution by stochastic models. These synthetic rain data can then be used as input for sewer network models. .. Read more (PDF, 136 KB)

Membrane stripping is an upcoming technology for removal of ammonia in the supernatant of WWTP. The reduced nitrogen return flow has several potential advantages, e.g. diminished N2O production, reduced carbon and oxygen demand in the biological step and production of a nitrogen fertilizer. Thus, ammonia stripping can reduce energy demand and GWP as well as increasing biogas yield. However, the process requires a considerable amount of acid and base. Read more (PDF, 273 KB)

As part of the Blue Diversion Autarky Project (www.autarky.ch), Eawag has devised an on-site water recycling system called the Water Wall. The system treats and recycles water for applications like hand washing and toilet flushing without the need for external water input. The combination of an aerobic bioreactor with ultrafiltration membrane, activated carbon filter and electrolysis flow cell for final disinfection provides multiple barriers for chemical and microbial contaminants.

keywords: drinking water production, membrane filtration, biofilm, Extracellular Polymeric Substances, hydraulic resistance

Bacteria inevitably colonize membrane filtration systems to form biofilms (van Loosdrecht et al. 2012). The formation of biofilms on membrane surfaces reduces permeate flux due to the increased hydraulic resistance. But practical experience indicates that avoiding the formation of biofilms is almost impossible. Eawag has thus developed a new paradigm for the operation of membrane systems, which consists in taking advantage of biofilms formed on membrane surfaces. Read more. (PDF, 116 KB)
