Waterborne enteric viruses that are commonly found in wastewater can cause several sporadic cases of diseases and outbreaks as a result of water or food contamination. Their detection, quantification, and effective removal from wastewater is of great importance. In this context, this review paper describes the different types of waterborne enteric viruses that are frequently… Continue reading Detection and removal of waterborne enteric viruses from wastewater: A comprehensive review
This research aimed at synthesizing polyethersulfone/α-zirconium phosphate (PES/ α-ZrP) flat-sheet nanocomposite ultrafiltration (UF) membranes. The impact of α-ZrP nanoparticle (NP) addition on the morphology, functionalities, hydrophilicity, and surface charge of the membrane, among others, were investigated. Different concentrations of α-ZrP NPs (0.25, 0.50, 0.75, and 1.00 wt.%) were tested. Membranes surface morphology was investigated by… Continue reading Development of Polyethersulfone/α-Zirconium phosphate (PES/α-ZrP) flat-sheet nanocomposite ultrafiltration membranes
This paper focused on the combination of membrane ultrafiltration, adsorption and ultrasound processes in one hybrid process called USAMe for improving membrane wastewater treatment performance and membrane fouling control. Different tests were conducted at different ultrasound frequencies and recycle ratio. Improved permeate quality in the USAMe process. Membrane fouling reduction with the combined application of… Continue reading Influence of membrane flux, ultrasonic frequency and recycle ratio in the hybrid process usame
In this study, commercial cellulose membranes were surface coated with alpha‑zirconium phosphate nanoparticles (α-ZrP-n) to study their impact on the overall removal efficiency of heavy metals from synthetic metal mixture wastewater solution. A total of four homogeneous solutions (0.25, 0.50, 0.75, and 1.00 wt%) of α-ZrP-n were prepared by sonicating the nanoparticles in deionized water.… Continue reading Synthesis of super hydrophilic cellulose-alpha zirconium phosphate ion exchange membrane via surface coating for the removal of heavy metals from wastewater
Abstract: Odor emissions are one of the major environmental impact generated by wastewater treatment plants (WWTPs) perceived by exposed population. Consequently, the control of odor emissions is a relevant aspect that must be considered in the management of the WWTPs. Any efficient strategy for odor control was based on direct and/or indirect monitoring and characterization… Continue reading A novel tool for odor emission assessment in wastewater treatment plant
Abstract: In the last decade, the membrane bioreactor (MBR) industry expanded and nowadays this technology is diffused worldwide for wastewater treatment. Nevertheless, membrane fouling is still a critical issue and most research is focused on this aspect in order to control the fouling phenomenon, such as the definition of foulant agents, which are mainly extracellular… Continue reading Control of fouling in MBRs through nanospheres addition
The occurrence and fate of pharmaceuticals in the environment, and in aquatic media in particular, have received considerable attention by the scientific community during the last two decades. Pharmaceuticals, which are designed to be biologically active substances, are usually lipophilic and resistant to biodegradation, thus having the potential for accumulation and persistence in the environment.… Continue reading Sonochemical degradation of twenty-three emerging contaminants in urban wastewater
One of the most popular means for removal of natural organic matter found in small concentration is by adsorption. Recent studies have found that ultrasound enhances adsorption properties of different adsorbents for many contaminants in aqueous solution. This work describes the results of investigation carried out to examine the adsorption process of phenol, as an… Continue reading Influence of ultrasound on phenol removal by adsorption on granular activated carbon
