[CEST2019_00870] Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
by Usťak S., Muňoz J.

The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both experiments with removal of selected HMs were performed with 0.1 M solutions of 5 different chelating agents: citric acid (CA), S-carboxymethyl-L-cysteine (SCLC), ethylenediamine disuccinic acid (EDDS), methylglycine diacetic acid (MGDA) and ethylenediaminetetraacetic acid (EDTA).

[CEST2019_00951] The importance of water for life on the planet: Education for Global Citizenship
by Tzaberis N.

The water shortage observed is due to the fact that the environment has undergone significant interventions that led to a qualitative degradation of water resources, overexploitation, pollution, the dropping of water level, salivation of aquifers, etc. The prevailing situation seems to be perpetuated possibly due to the interests involved, attitudes, perceptions, and lack of awareness of the seriousness of the problem.

[CEST2019_00468] Optimization of decentralized treatment and sanitation of domestic wastewaters via constructed wetlands: The DOMUS_CW project
by Ntaikou I., Antonopoulou G., Drakopoulos V., Dailianis S., Lyberatos G.

Two free surface flow CWs constructed in one Greek and one Cypriot community, were upgraded in order to serve as case studies to be further optimized via modeling. Through the systematic and detailed monitoring of the two CWs their operational efficiency was evaluated, and the response to operational factors that have not been extensively studied yet, such as supply variations and recirculation, were recorded and incorporated into the model.

[CEST2019_00475] Wastewater disinfection applying solar energy
by Zkeri E., Vourdoubas I., Katsivela E.

Solar Water Disinfection Process (SODIS) is a simple technology using solar UV-A radiation (wavelength 320-400 nm) and elevated water temperature to inactivate pathogens. In the present survey, the effect of solar radiation on the disinfection of domestic secondary treated wastewater from the Wastewater Treatment Plant (WWTP) of the Municipality of Chania (Crete, Greece) was investigated during the day hours in summer.

[CEST2019_00981] Modeling and optimization of two-phase olive-oil washing wastewater phenolic compounds recovery and treatment by novel weak-base ion exchange resins
by Ochando-Pulido Javier M., Rubén González-H., Martínez-Férez A.

In the present work, the concentration and recovery of high-added value phenolic compounds from two-phase olive mill wastewater (OMW) and the simultaneous effluent treatment by a ‘green process’ based on resins adsorption/ion exchange was studied. Olive oil is produced by a technological procedure based on physical operations, without use of chemicals. This industry is concerned to make the whole process environmentally friendly, which includes the treatment of the wastewater produced in the mills. The proposed weak-based IE process was statistically optimized and modelled.
