SELECTED APPLICATIONS of CAVITATION BASED ADVANCED OXIDATION PROCESSES (AOPs) for TREATMENT of WATER and INDUSTRIAL EFFUENTS

Fedorov K., Cako E., (Corresponding) Boczkaj G.
Topic: 
Advanced oxidation processes
Cavitation phenomenon was effectively applied for enhancement of Advanced Oxidation Processes (AOPs) effectiveness. Main applications are focused on treatment of water as well as industrial effluents [1-2]. Cavitation phenomenon can be generated in the liquid by intentionally formed differences in...Read more

Topic: 
Wastewater-based epidemiology to monitor covid-19 outbreak: present and future diagnostic methods to be in your radar
Monitoring SARS-CoV-2 presence in wastewater has been carried out since April 2020, when the new disease COVID-19 began to spread rapidly in the Czech Republic. The aim of this study was to detect viruses in order to evaluate the possibility of using wastewater analysis as one of the tools for the...Read more

Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids

(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.
Topic: 
Advanced oxidation processes
This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...Read more

The potential impact of an implementation of microalgae-based wastewater treatment on the energy balance of a municipal WWTP in Central Europe

(Corresponding) Hasport N., Krahe D., Kuchendorf C., Theilen U., Beier S.
Topic: 
Environmental biotechnology and bioenergy
The integration of a photobioreactor for wastewater treatment by microalgae is proposed as a future alternative for cost-efficient and environmentally friendly nitrogen and phosphorous removal in municipal WWTPs. The high growth rates and higher biogas yields (compared to conventional sewage sludge...Read more

Alternative wastewater treatment process with algae (AlgA) – general mathematical model and dynamic simulation

(Corresponding) Lorenz T., Behr A., Theilen U.
Topic: 
Wastewater treatment
Conventional wastewater treatment systems are based on processes including the steps of pre-/ primary, sec-ondary and finally the sludge treatment. In this study a treatment step with algae as an alternative secondary treatment is supposed to improve the biological nutri-ent removal efficiency. In...Read more

New polyacrylonitrile (PAN)-based porous carbons for the removal of industrial wood dyes from aqueous solutions

Domínguez-Ramos L., Tejado I., Gómez-Díaz D., Freire S., Lazzari M., (Corresponding) González-Álvarez J.
Topic: 
Wastewater treatment
Synthetic dyes degradation is a difficult task due to their complex aromatic structure, although its elimination by adsorption is effective. The aim of this research is to produce porous carbons derived from polyacrylonitrile (PAN) as wood dyes adsorbents. PAN is a nitrogen-rich precursor...Read more

Presence and removal of Organic Micropollutants in 8 different Wastewater Treatment Plants and Risk Assessment of treated effluent

(Corresponding) Di Marcantonio C., Chiavola A., Meccoli L., Leoni S., Calchetti T., Gioia V., Mancini M., Frugis A., Cecchini G., Ceci C., Spizzirri M., Boni M.
Topic: 
Wastewater treatment
Increasing attention has been paid in the recent years to the presence of Organic MicroPollutants (OMPs) in water, being considered a source of a high risk for public health and environment (Rodriguez-Narvaez et al., 2017). The present study belongs to a wide research activity carried out since...Read more

Planar Mixing Tool for Enhanced Performance of Covered Anaerobic Pond Systems

(Corresponding) Brück F., Velten H., Pingsmann M., Meyer D., Weigand H., Linnenberg C., Theilen U.
Topic: 
New solutions for a better and sustainable agriculture
Pond systems are the simplest and most widespread technology for the treatment of high-strength wastewater containing biodegradable suspended solids. When covered, they offer significant advantages such as odour control, intensification of the decomposition process, and the potential to capture...Read more

Evaluation of the potential of four microalgal-bacterial symbiotic association on wastewater treatment and lipid accumulation

Talapatra K., Mittal V., (Corresponding) Ghosh U., Gautam R.
Topic: 
Environmental biotechnology and bioenergy
Microalgae-bacteria symbiotic systems have demonstrated greater benefits over the pure culture of microalgae. The existence of certain bacteria will increase the quality of sewage purification and also reduce the associated high capital cost for maintaining the pure culture of microalgae. In this...Read more

Modelling the hydrothermal carbonization of cheese whey wastewater in Lesvos island: an application of the 3-step evolution model

Chatzimaliakas P., (Corresponding) Vakalis S.
Topic: 
Biowaste
Lesvos island has an extensive dairy production sector, and -at present- eighteen dairy processing facilities are operating. Efficient management of the liquid biowaste effluents has been an issue of interest since the scope is the minimization of the environmental impact. The operating dairy...Read more
