Kinetics study of the MO adsorption and photocatalytic degradation using an effectively engineered HF photocatalyst
(Corresponding) Theodorakopoulos G., Katsaros F., Papageorgiou S., Romanos G.
Topic:
Water treatment
In this study, copper decorated photocatalysts (Degussa P25), were shaped in the form of ceramic hollow fibers (HFs) and their photocatalytic properties were investigated using Methyl Orange (MO), a prototype anionic pollutant. The abatement of the dye was tested in dark and under UV irradiation by...Read more

Synthesis of Fe3O4/Carbon Quantum Dots Hybrid for Efficient Removal of Congo Red Dye from Aqueous Solution
(Corresponding) Zourou A., Axarli V., Falara P., Ntziouni A., Kordatos K.
Topic:
Water treatment
During the past decades, the release of toxic pollutants into aquatic environment has continuously increased due to rapid industrialization and civilization. The presence of organic dyes, such as Congo Red (CR), can be dangerous to both human and aquatic life. Therefore, their removal is an...Read more

Photocatalytic elimination of water pollutants using innovative titania thin film heterostructures embedding carbon quantum dots
(Corresponding) Falara P., Zourou A., Ibrahim I., (Corresponding) Kordatos K.
Topic:
Water treatment
Titanium dioxide based photocatalysis is a well-established advanced oxidation process (AOP) that recently has expanded its borders comprising advanced reduction processes (ARPs) as well. To enhance the photocatalytic activity, titania heterostructures embedding semiconductors, or clays, or...Read more
Activated carbon-polyethyleneimine-alginate composite fiber for scavenging pharmaceuticals with different charges from aqueous solutions
Dangi Y., Choi J., Lim C., Song M., Han M., Lin X., (Corresponding) Yun Y.
Topic:
Water treatment
Activated carbon (AC) is a potential adsorbent for water purification, though it is difficult to separate after use. To solve this problem, for the first time, the ternary composite fiber (ACPEIA) of AC, polyethyleneimine (PEI), and alginate (A) was fabricated as a multifunctional adsorbent for...Read more
Preliminary study on fluoride removal from contaminated groundwater by nanofiltration
(Corresponding) Fuoco I., Apollaro C., Criscuoli A., De Rosa R., Figoli A.
Topic:
Water treatment
In this work, a commercial nanofiltration (NF) membrane, named SPR 10113, was used for the first time to treat a real F-contaminated groundwater (F= 8.9 mg/L) coming from deep crystalline aquifer of Calabria Region (Southern Italy), in order to verify its efficiency in terms of fluorine rejection...Read more

Modelling the operation of a Water Treatment Plant based on Artificial Neural Networks
(Corresponding) GYPARAKIS S., TRICHAKIS I., VAROUCHAKIS E., DIAMADOPOULOS E.
Topic:
Water treatment
The main purpose of this study is to model the operation of a Drinking Water Treatment Plant (DWTP) using its main operational and water quality parameters in a fast, easy and reliable way. This study is based on a large number of data from recent years (2019-2021). The DWTP has a maximum capacity...Read more
Enhanced-Electrocoagulation For Organic Matter Removal From Surface Drinking Water Sources: Operational Parameters And Energy Consumption
(Corresponding) Daraei H., Intwala P., Awad J., Bertone E., Chow C., Duan J., Stewart R., Leuuwen J.
Topic:
Water treatment
In this study, an Enhanced Electro-Coagulation (En-EC) technique is described for the removal of dissolved organic carbon (DOC) from surface drinking water sources. Assessment of the En-EC technique included investigation of the impacts of operational factors on the organic removal efficiency (R%)...Read more

Continuous Flocs Image Analyser (C-FIA) For Flocs Dynamics Tracking During Conventional Water Treatment
(Corresponding) Daraei H., Bertone E., Khedher M., Chow C., Awad J., Akyol B., Duan J., Leeuwen J., STEWART R., Intwala P.
Topic:
Water treatment
In this paper an image analyser termed ‘Continuous Floc Image Analyser (C-FIA)’ developed for tracking the dynamics of floc formation, growth and settling during conventional water-treatment (i.e. coagulation, flocculation, and settling processes) is described. The C-FIA is proposed as an...Read more
Risk analysis of pathogenic organisms during soil-aquifer treatment: application to a coastal aquifer in Cyprus
(Corresponding) Panagiotou C., Karaolia P., Papanastasiou P., Sprenger C.
Topic:
Water treatment
A quantitative microbial risk analysis of Ezousa (Cyprus) Managed Aquifer Recharge (MAR) site is presented herein to evaluate the health risks associated with the pathogenic fraction of three microorganisms: the bacterium Escherichia Coli (E. Coli), the Rotavirus and the protozoan Giardia...Read more
Electro-bioremediation of nitrate contaminated saline groundwater
(Corresponding) Puggioni G., Carucci A., Dessì E., Pous N., Puig S., Unali V., Milia S.
Topic:
Water treatment
Sustainable exploitation of coastal aquifers is often hindered by the presence of contaminants and high salinity levels. This study proves for the first time the electro-bioremediation of nitrate contaminated saline groundwater. Two 3-chamber bioelectrochemical systems (BES) were operated in...Read more
