“…The hydrophobicity of PhACs is typically evaluated using the octanol-water partition coefficient of a compound (KOW) or its logarithm (log KOW) that can be used as a descriptor of the sorption potential and bioaccumulation of a compound in the aquatic environment. Log KOW is generally used for uncharged (neutral) compounds [51]. In this study, acetaminophen, caffeine and erythromycin existed as neutral species during all the experiments.…”

This study investigates the influence of feed solution pH and fouling on the rejection of ten selected pharmaceutically active compounds (PhACs) with different physicochemical characteristics (molecular weight, water solubility, log KOW, pKa, dipole moment…) by three multichannel ceramic ultrafiltration membranes, ranging from 1 to 8 kDa, in order to improve their removal from water. For this purpose, the comparison between filtration of PhACs in deionised water (Feed I) and in real wastewater effluent (Feed II) was performed, demonstrating that the variation of pH and the formation of a foulant layer altered the separation mechanism and hence the rejection values of each PhAC varied. Higher rejections of most of the PhACs were

“…Among these technologies, membrane has emerged as one of the most promising physical treatment processes and has a proven track record in various wastewater treatment systems [32]. Membrane processes are not only more effective than conventional processes but its versatility lies in the capability to be integrated or hybridized with other treatment technologies, giving the whole treatment system greater capability in removing multiple undesired pollutants [33]. Similar to conventional pressurized-membrane processes, FO has also found its potential in wastewater treatment processes, where it can be used for concentration: reducing the amount of wastewater or extracting clean water from the wastewater by using draw solution.…”

Study of forward osmosis (FO) has been increasing steadily over recent years with applications mainly focusing on desalination and wastewater treatment processes. The working mechanism of FO lies in the natural movement of water between two streams with different osmotic pressure, which makes it useful in concentrating or diluting solutions. FO has rarely been 2 operated as a stand-alone process. Instead, FO processes often appear in a hybrid or integrated form where FO is combined with other treatment technologies to achieve better overall process performance and cost savings. This article aims to provide a comprehensive review on the need for hybridization/integration for FO membrane processes, with emphasis given to process enhancement, draw solution regeneration, and pretreatment for FO fouling mitigation. In general, integrated/hybrid FO processes can reduce the membrane fouling propensity; prepare the solution suitable for subsequent value-added uses and production of renewable energy; lower the costs associated with energy consumption; enhance the quality of treated water; and enable the continuous operation of FO through the regeneration of draw solution. The future potential of FO lies in the success of how it can be hybridized or integrated with other technologies to minimize its own shortcomings, while enhancing the overall performance.

Emerging contaminant (triclosan) identification and its treatment: a review

et al. 2019

Pollutants from personal care products (PCPs), pharmaceuticals, industrial wastes, food additives, pesticides and fertilisers are classified as emerging contaminants (ECs). These ECs have been given much attention due to their deleterious effects on human life, plants and animals. Triclosan (TCS), a broad spectrum antibiotic, is under the category of emerging contaminants; it is shown to have an eco-toxicity. It is a ubiquitous contaminant due to its wide range of applications in PCPs as an antibacterial agent. Inefficacy in the conventional treatment of wastewater which is being discharged into natural streams has led to the bioaccumulation of TCS. Concentrations of TCS have been detected in several wastewater treatment plants and urinary samples of humans and streams. In surface waters, TCS was detected in Korea, USA, Europe, China, Japan and India. In order to overcome the astringent effects of TCS, there is a need for its treatment. This paper addresses studies conducted on methods of treating TCS, and among all the methods, membrane technology (MT) was found to be effective and this is mainly due to hydrophilic nature of TCS, high log K ow value (4.8), and a removal efficiency > 95% was observed when powdered activated carbon of 100 mg/l was combined with MT.
