Selective transport between monovalent and divalent ions in electrodialysis: The effect of current density and ionic species concentration

Industrial and municipal wastewaters often contain a high concentration of NH4+<br/>To prevent excessive discharge into the environment, these wastewaters need to be treated. Electrodialysis has been shown to be a suitable technique for the removal and recovery of NH4+ from both synthetic and real wastewaters such as digestate rejection water...

The negative effect of carbohydrates on protein degradation in the acid-phase of anaerobic digestion of protein-rich wastewater: a microbial composition study

Anaerobic digestion (AD) is a promising technology to process protein-rich wastewater. However, incomplete protein degradation during the acidification of organic matter is frequently observed when carbohydrates are present. Literature reports little information to explain the mechanisms behind this phenomenon. This MSc study investigated the...

Effect of magnetite nanoparticles on methanogenic degradation of p-cresol in anaerobic membrane bioreactor

Anaerobic membrane bioreactor (AnMBR) is a promising technology to treat phenolic wastewater. Conductive materials such as magnetite and granular activated carbon have been reported to be capable of improving anaerobic digestion by facilitating direct interspecies electron transfer (DIET). This research first investigated the effect of magnetite...

Impact of Intermediate and End-Products of Anaerobic Digestion on Sludge Filterability: Understanding fouling in AnMBRs

Water scarcity is a severe problem that needs to be faced to avoid devastating effects in future generations (WWAP, 2017). Changes need to be made in the direction of a circular economy, where water is used wisely and wastewater is not an end product, but a resource mine (2030 WRG, 2015). To do so, there are available technologies with great...

Anaerobic digestion of sludge from brackish aquaculture recirculation system: CSTR performance, analysis of methane potential and phosphatase, struvite crystallization

The marine/ brackish recirculating aquaculture system (RAS) is a sustainable and environment-friendly cultivating system to meet the increasing demand of aquatic animal protein for the human consumption. However, the increasing amount of aquaculture waste becomes problematic for further application and demands much research attention on it. To...

Cold Anammox: Anammox at low temperatures

Membrane fouling of AnMBR in hyper saline condition

Membrane fouling problem is one of the most crucial issues which restricts the development of MBR and is, therefore, the prime research topic for many researchers worldwide. Anaerobic MBRs offer interesting perspectives as a potential solution for the treatment of wastewaters under extreme conditions, e.g. high temperature and/or high salt...
