Abstract

The detection of substrate clogging is crucial for the sustainable operation of treatment wetlands. Electrical resistivity methods have shown promise for non-destructive detection of clogging, but their effectiveness in identifying different types of clogging has not been identified. This study explores the feasibility of using the resistivity method to detect organic-dominated, inorganic-dominated, and combined organic-inorganic clogging during the drainage phase of vertical flow treatment wetlands. Results reveal that the amount of clogging matter accumulation and the corresponding hydraulic resistance follow the order: combined organic-inorganic > organic-dominated > inorganic-dominated clogging. Organic clogging matter generates greater hydraulic resistance than inorganic matter for the same mass, whereas hydraulic resistance does not correlate consistently with the water flow regime. The study establishes a direct link between the hydraulic effects of different types clogging matters and their corresponding conductivity. Linear regression analysis shows moderate positive correlations for total solids (R2 = 0.56) and a stronger positive relationship for volatile solids (R2 = 0.81) with conductivity. Additionally, conductivity is negatively correlated with substrate permeability (R2 = 0.93). The conductivity of the wetland substrate under drained conditions is influenced by its water retention capacity, which is closely related to the hydraulic resistance of the clogging matter. This study introduces a non-destructive method to identify both organic and inorganic clogging and assess their impact on substrate hydraulic permeability. The application of this method enables real-time, non-invasive assessment of substrate clogging distribution and severity in wetland systems, enhancing the ability to effectively monitor and maintain wetland performance.

期刊介绍: The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
