Wastewater treatment

Anionic and non-ionic surfactants have been detected in the influents to and effluents from wastewater treatment plants (WWTPs). Linear alkylbenzene sulphonates (LAS) and alkylphenol ethoxylates (APEO) are the most frequently detected anionic and non-ionic surfactants in urban wastewater. The aim of this study was to assess the effect of the presence of anionic and non-ionic surfactants in the influent to WWTPs on activated sludge processes.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

The main aim of this research is to develop a viable solution to treat and reuse car wash wastewater. To do so, two treatment systems were evaluated. The first treatment system comprised of coagulation-flocculation and ceramic ultrafiltration membrane and reverse osmosis and the second treatment system is enhanced membrane bioreactor (eMBR).

The aim of this study is to enhance biogas production from the organic fraction of municipal solid waste (OFMSW) and garden waste (GW) via pretreatment and codigestion. In order to achieve the aims of the study, two objectives have been developed and are outlined below: To investigate an optimum co-digestion mixture of OFMSW with untreated and pretreated GW; to investigate the effectiveness of different pretreatments on the potential for biogas production from GW and to identify the relationship between certain changes in GW characteristics and enhanced yield.

MBR (Membrane Brio-Reactor) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. Set up of MBR plant is mainly utilizing a bioreactor and membrane filtration as one unit process for wastewater treatment thereby replacing, and in some cases supplementing, the solids separation function of secondary clarification and effluent filtration, resulting the possibility to eliminate the secondary clarification and operate at higher MLSS concentration....
