[CEST2019_00302] Printing ink wastewater treatment using electrocoagulation
by Papadopoulos K.P., Argyriou R., Ekonomou C.N., Tatoulis T.I., Tekerlekopoulou A.G., Vayenas D.V.

Packaging paper wastewaters, stemming mainly from the dyeing sector of the production process (where printing inks are utilized), are characterized by large concentrations of organic matter, deep, strong color and almost zero biodegradability factor. These attributes, in combination with the presence of some toxic compounds (heavy metals, VOCs etc.) make further treatment necessary, before releasing the wastewater to the environment.

[CEST2019_00273] The Use of Biochar from Waste Wooden Biomass for Removal of Emerging Pollutants
by Žgajnar Gotvajn A., Carvalho A.P., Marinšek M.,Kalčikova G.

The aim of presented research is to use biochar produced from waste biomass for removal of veterinary antibiotic tiamulin from model wastewater. Produced biochar was activated using different chemical methods (KOH treatment under various conditions). It was characterised using BET method for the determination of the pore size distribution and pore volume fraction as well as SEM microscopy. Results indicated importance of biochar activation to achieve applicable adsorption characteristics. In 180 minutes of batch experiment up to 78% of tiamulin was removed.

[CEST2019_00251] Challenges in biological treatment plants: the approach of zero sludge waste
by Theofanidis S.A., Samiotis G., Bellos D., Pekridis G., Tsioptsias C.,Amanatidou E.

The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete retention of solids.

[CEST2019_00169] Phosphorus and nitrogen recovery from wastewater in the form of struvite: alternative magnesium sources
by Primikyris G., Siahos K., Vavouraki A., Putnis C.V., Natsi P.D., Koutsoukos P.G.

Recovery of phosphorus and nitrogen from municipal and other types of wastewater may be achieved through the direct crystallization of struvite (magnesium ammonium phosphate hexahydrate, Mg•NH4•PO4•6H2O). Wastewater deficiency in magnesium makes it necessary for the external addition of magnesium to make up for the supersaturation needed. In the present work we have tested artificial seawater and saturated with respect to calcined magnesia (MgO) aqueous solutions as magnesium sources, as both sources are low cost and readily available.
