Special Issue Information

Dear Colleagues,

Water quality is a critical global issue that affects human health, the environment, and the economy. The increase in pollution levels and the growing demand for clean water have led to the development of various water-treatment technologies. In recent years, technological advancements have provided new opportunities to improve the effectiveness and efficiency of water-quality-improvement technologies.

In this Special Issue, we aim to bring together cutting-edge research and innovations on developing new water-treatment technologies and their applications in addressing emerging pollutants and other water-quality challenges. Hence, we invite original research articles, reviews, and perspectives on developing and applying advanced technologies for water treatment and pollution control. The topics of interest include but are not limited to:

  • Novel water-treatment processes and technologies;
  • Membrane-filtration and desalination techniques;
  • Modeling and optimization of water-treatment processes;
  • Internet of Things (IoT)-based smart wastewater-treatment model; 
  • Advanced oxidation processes for water disinfection and contaminant removal;
  • Sustainable and eco-friendly approaches to water treatment;
  • Technologies for removal of emerging contaminants in wastewater;
  • Application of machine-learning (ML) techniques to model wastewater treatment;
  • Applications of nanotechnology in water treatment;
  • Advanced in sludge and biosolid treatment;
  • Applications of bioelectrochemical technologies in water treatment.

The ultimate goal of this Special Issue is to provide a platform for researchers, engineers, and policymakers to share their latest findings and insights, and to foster interdisciplinary collaborations in the field of water-quality-improvement technology.

We look forward to receiving your contributions.

Generating rapid, easy-to-interpret community data for drinking reservoirs as a means of tackling water quality management is of increasing demand within the water industry. Taste and odour (T&O) is one of many increasing concerns to water companies worldwide, incurring huge costs as customer complaints accumulate and additional treatment and resource management are required. However, there remains a two-fold issue in addressing T&O management: firstly, predicting the initial onset of a T&O event relies on a highly complex understanding of environmental considerations and their interaction with T&O-related taxa, and secondly, there remains a lag between the notification of a T&O event and the resolution of the issue by reservoir management staff. This is partly due to slow, low-resolution methods of detecting and reliably identifying problem taxa in samples. These methods are unable to provide information on the huge plethora of taxa related to T&O metabolite production and often cannot provide data in a timely enough manner for an opportune management response. This means the water industry is often forced to use a reactive, rather than proactive, approach to water quality monitoring. Here, we present methods for implementing a high-throughput sequencing approach to monitoring drinking reservoirs for water quality and improving the sustainability of water supplies, as well as methods for presenting these data on easy-to-interpret data dashboards that can be updated rapidly as new data are generated. Our methods and dashboarding approaches are currently being trialled and tested within the UK water industry, and so here, we show anonymised examples of those data presentations. We propose that these methods can greatly aid reservoir management teams in their approach to T&O monitoring and can be used to implore more sustainable management pipelines, safeguarding future water sources.

Water contamination with organochlorine pesticides (OCPs) is strongly linked to agricultural practices, and it still represents an environmental issue, despite the OCPs bans in many countries and despite the reported sustainable remediation technologies for their removal. Considering the environmental persistence of OCPs, the imbalances produced in the ecosystem, and the bioaccumulation tendency in living organisms through the food chain, the monitoring of OCPs and of their metabolites has crucial importance. The accuracy of the results obtained is strongly connected to the selection of reliable and accurate analytical procedures, especially considering the multitude of challenges related to OCP quantification. The purpose of this paper is to present an overview of the analytical techniques and protocols reported for OCP assessment in water, and to offer scientists a presentation of the current state of the literature on this subject. Nevertheless, it must be considered that each method has advantages and disadvantages, and, in most cases, the protocols reported in the literature must be adapted and improved. In addition, the levels of OCPs identified in surface water, groundwater, and rainwater have been reviewed. This review paper is directly connected to sustainability practices, since environmental sustainability is related to the responsibility to conserve natural resources and to prevent pollution, and for scientists, these objectives are fulfilled by conducting chemical analyses to track and quantify pollutants, as part of environmental studies.

Water pollution has become a major environmental menace due to municipal and industrial effluents discharged into water bodies. Several processes have been devised for the treatment and disposal of wastewater and sludge. Yet, most of the conventional technologies do not meet the requirements of sustainability as they impose a higher load on the environment in terms of resource depletion and toxic waste generation. Recently, sustainable innovative technologies, like hydrodynamic cavitation (HC), have emerged as energy-efficient methods, which can enhance the conventional wastewater treatment processes. HC is a very effective technique for the intensification of processes, like aeration, activated sludge treatment, and anaerobic digestion processes in conventional wastewater treatment plants, particularly for the enhanced degradation of persistent pollutants. On the other hand, advanced oxidation is a proven enhancement method for wastewater treatment. This review provides a comprehensive overview of recently published literature on the application of HC for the treatment of persistent organic pollutants. The potential synergistic impact of HC coupled with advanced oxidation and alternative pre-treatment methods was also reviewed in this study. Moreover, an overview of the present state of model-based research work for HC reactors and a feasibility analysis of various advanced oxidation process is also covered. Options for the pilot-to-large scale implementation of HC and advanced oxidation technologies to ensure the better sustainability of wastewater treatment plants are recommended. Full article
