Phosphorus and nitrogen recovery from wastewater in the form of struvite: Alternative magnesium sources
(Corresponding) Koutsoukos P., Primikyris G., Siachos K.
Topic:
Wastewater treatment
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...Read more
MONITORING OF TREATED DOMESTIC WASTE WATER QUALITY
Poulli K., (Corresponding) Ero R., Kozakou S., Michael N., Demetriou E., Christofidou M., Aletrari M.
Topic:
Wastewater treatment
Cyprus is experiencing severe water supply deficiency. Particularly in summer months the situation is aggravated mainly due to low precipitation, high evaporation and increased demands for irrigation and tourisms. The use of treated wastewaters for environmental purposes such as recharging aquifers...Read more
IMPREGNATED RESINS AS NOVEL SORBENTS FOR REMOVAL OF TOXIC METAL IONS FROM AQUEOUS SOLUTIONS
(Corresponding) Zawierucha I., Nowik-Zajac A., Kozlowski C.
Topic:
Wastewater treatment
The adsorption/solid phase extraction (SPE) processes are the most attractive methods for effective removal of metals ions from different aqueous solutions. In SPE procedure, the choice of appropriate adsorbent is a critical factor to obtain full recovery and high enrichment factor.
For this...Read more

Challenges in biological treatment plants: the approach of zero sludge waste
THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic:
Wastewater treatment
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...Read more
REMOVAL OF TOXIC METAL IONS THROUGH POLYMER INCLUSION MEMBRANES CONTAINING MACROCYCLIC LIGANDS AS CARRIERS
(Corresponding) Nowik-Zajac A., Zawierucha I., Kozlowski C.
Topic:
Wastewater treatment
More strict environmental regulations on the discharge of toxic metals require developing various technologies for their removal from polluted streams. The separation of toxic metal ions using immobilized membranes with doped ligands, due to their high selectivity and removal efficiency, increased...Read more
Keywords:
polymer inclusion membranes, macrocyclic ligands, toxic metal ions
According to the latest environmental requirements, zero liquid discharge principle must be considered in all modern manufacturing processes. In principle, solid waste can be achieved only by evaporation plus crystallization, and therefore reverse osmosis is usually applied to decrease the...Read more

The use of biochar from waste wooden biomass for removal of emerging pollutants
(Corresponding) Žgajnar Gotvajn A., Carvalho A., Marinšek M., Kalčikova G.
Topic:
Wastewater treatment
Biochar can be produced usig variety of waste biomass to achieve goals of zero waste management and circular economy. It has been used as adsorbent in the past for water and wastewater treatment. Recetly, the application of natural porous materials for removal of emerging pollutants gained a lot of...Read more
Pretreatment of antibiotics-contaminated waste biological sludge by ozonation
Boševski I., (Corresponding) Kalčikova G., Derco J., Žgajnar Gotvajn A.
Topic:
Wastewater treatment
Ozonation was studied as a pretreatment method for a waste biological sludge, contaminated with large amounts of globally used antibiotics; tiamulin, levofloxacin and amoxicillin. At the concentrations of over 100 mg L-1, these antibiotics were found to inhibit biogas production (up to 50%), which...Read more
Printing ink wastewater treatment using electrocoagulation in lab- and pilot-scale
Papadopoulos K., Argyriou R., Economou C., Tatoulis T., Tekerlekopoulou A., (Corresponding) Vayenas D.
Topic:
Wastewater treatment
Packaging paper wastewaters, stemming mainly from the dyeing sector of the production process (where printing inks are utilized), are characterized by high concentrations of organic matter, intense color and almost zero biodegradability factor. These physicochemical characteristics, in combination...Read more
Keywords:

Biotreatment of Brewery Wastewater Using the Filamentous Cyanobacterium Leptolyngbya sp.
Papadopoulos K., Economou C., Moustaka-Gouni M., Tekerlekopoulou A., Aggelis G., (Corresponding) Vayenas D.
Topic:
Wastewater treatment
Brewery wastewater is generated from the beer brewing process in large amounts (4-8 m3 per m3 of beer produced). Brewery wastewater consists of high organic matter content, significant nitrogen and phosphorus concentrations and easily biodegraded compounds. Even though most biological treatment...Read more
