With the rapid growth of economic development, the circular economy has been raised in many international environmental and socio-economic conferences and forums nowadays. The recycling of plastic waste was one of those aspects. This paper studied the potential of directly reusing plastic bottle caps as bio-carriers in moving bed bioreactors without further waste processing.

The aim of this study was to design and characterize a NdFeO3-based photocatalyst prepared by sol-gel method for treatment of oily wastewater. Different characterization techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophometer were used to elucidate the structure, morphology, surface functional groups, and optical absorption properties of the prepared NdFeO3 photocatalyst.

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.
