Connecting AnMBR and SOFC for Blackwater Treatment and Energy Production: Influence of the AnMBR pH on the SOFC Operational Strategy

Driven by the increasing demand for waste reduction and green energy production, an integrated system which combines an anaerobic membrane bioreactor (AnMBR) and a solid oxide fuel cell (SOFC) was proposed in this research project for blackwater treatment and energy production. The potentials of using an AnMBR for wastewater treatment and biogas...

Energy efficiency and treatment performance of BPM-ED for ammonium recovery from ammonium sulphate and ammonium citrate scrubbing effluents

Excess nitrogen disposal into the environment increased with the discovery of an artificial way of nitrogen gas conversion to ammonia, and its implementation to industrial scale. The excess wasted fixed nitrogen ended up in rivers, lakes, oceans which resulted in degrading air, water and soil due to exceedance of the amount of nitrogen that can...

Economic and cost-effectiveness analysis of integrated desalination and brine treatment systems

The brine generated from desalination is a threat to the environment, and its disposal has been a great challenge. A new concept Zero liquid discharge (ZLD) can minimize the environmental impact of brine. However, the high costs for construction and running of a ZLD plant limits its growth in desalination market. Therefore, a new strategy...

Comparison of Concentration Performance and Energy Consumption in Reverse Osmosis, Vacuum Membrane Distillation, and Electrodialysis for Brine Treatment

Brine producing industries progressively become the centre of attentionas they carry greater environmental consequences. Despite the extensiveliterature that can be found on desalination, limited information is availableabout the practical comparison of the technologies with regards to the brineconcentration performance and associated energy...

Evaluating toxicity in the anaerobic treatment of paper pulping effluents and the biological performance of EGSB reactor

Pulp and paper industries are water-intensive industries and composed of complex production processes. Untreated pulping wastewater is very toxic and lethal to aquatic life if discharged untreated. Anaerobic treatment technology has gained interest in treating these types of wastewater by reducing organic compounds. This thesis research aimed to...

Iron Removal in Low Salinity Water: A case study of brackish water reverse osmosis permeate

A reverse osmosis (RO) membrane followed by a packed tower aerator and rapid sand filter are used by an agricultural company in Emmen to treat brackish groundwater to supply water for growing crops and cleaning purposes. The iron removal by the treatment plant is sufficient most of the time throughout the year. However, the farmer periodically ...

Mitigation of Silica Scaling by Closed-Circuit Reverse Osmosis

Reverse osmosis (RO) is considered the most reliable and cost-effective membrane desalination technologyworldwide. However, it suffers significant performance limitations due to mainly inorganic foulinggenerated in the highly concentrated brine. Especially, scaling caused by silica and silicates depositionsresults in irreversible damages with...

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...

Biodegradability Assessment of Aniline under Methanogenic and Saline Conditions in Batch and AnMBR

Aniline, a toxic aromatic amine present in certain wastewaters from the petroleum-, pharmaceutical- , and textile industry is regarded recalcitrant under strict anaerobic conditions. This study assessed the feasibility of methanogenic aniline biodegradation under saline (8 gNa+/L) conditions (1) by performing biodegradability batch assays using...

Direct Nanofiltration of Surface Water: Investigating the fouling and rejection performance of low MWCO hollow fiber nanofiltration membranes

In this thesis, direct application of hollow fiber nanofiltration on surface water is suggested as an efficacious method for surface water treatment.

The current research aims to assess the performance of these membranes as a potential solution for surface...

Modelling Phenol Degradation Under Saline Conditions by AnMBR Biomass

This study is part of a project titled: “Phenolic compounds degradation in AnMBR under mesophilic and thermophilic operation: BioXtreme-following up”. <br/>Phenol is a toxic contaminant found widely in industrial effluents. It is toxic to humans and animals even at very low concentrations. Anaerobic digestion uses phenol as a carbon source and...

Selective Transport of NH₃ by Silica-Based Ceramic Pervaporation Membrane

Nitrogen (N) removal is one of the key tasks for every wastewater treatment plant under the growing pressure of environmental protection. Prevailing applied N treatment technologies are mostly energy-intensive. This dilemma triggers a rethinking of the way to approach N management. “N2kWh-From pollutant to power” is a project that aims at...

Silica Scaling in Closed-Circuit Desalination (CCD)

With the growing population and industrial development, there is more stress on natural water resources. Additionally, environmental laws make the disposal of waste streams from industries difficult.
