Treatment of various agro-industrial wastewaters using electrocoagulation
Benekos A., Papadopoulos K., Triantaphyllidou I., Tekerlekopoulou A., (Corresponding) Vayenas D.
Topic:
Wastewater treatment
Greece, although not over-industrialized, is facing issues connected to pollution of its water resources, as conventional wastewater treatment methods often prove ineffective in terms of removing some pollutantssuch as suspended solids and pigments. Therefore, the need of developing efficient,...Read more
RECOVERY AND SEPARATION OF VALUABLE METALS (COPPER AND ZINC) FROM ACIDIC MINE WATERS BY ION-EXCHANGE RESINS
(Corresponding) Vecino X., Reig M., López J., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were...Read more

Removal of wood dyes from aqueous solutions by sorption on un-treated pine sawdust
Pimentel C., Freire S., Gómez-Díaz D., (Corresponding) González-Álvarez J.
Topic:
Wastewater treatment
Synthetic dyes are extensively used in industry for various applications among which is the preparation of dyed wood veneers. The discharge of effluents containing dyes is of great concern due to their toxicity, mutagenicity and carcinogenicity and causes serious environmental problems. In this...Read more
Treatment of three agro-industrial wastewaters by dried bio-absorbent orange peels and brewery spent grains
Kiouranakis G., Ioannou Z., Gkatzionis K., Papanikolaou S., (Corresponding) Sarris D.
Topic:
Circular economy and industrial symbiosis
This study aims to determine the efficiency of reducing the phenol content (hence BOD/COD) of three agro-industrial wastes: olive mill effluent- olive mill wastewaters- OMW, brewery sludge – BS, and white wine lees – WWL by orange peel (OP) and dried brewer' spent grains (BSG). Orange peels...Read more
