3D printed lab-scale raceway ponds reactors for photo-Fenton processes
Nasr Esfahani K., Zandi M., Travieso-Rodriguez J., Graells M., (Corresponding) Perez-Moya M.
Topic:
Advanced oxidation processes
Abstract
Raceway pond reactors (RPRs) have been widely used in microalgae mass culture (Acien et al., 2013) and their application for micro pollutant removal in photo-Fenton processes has been recently assessed (Rivas et al., 2015). The main advantages of raceway pond reactors are being low cost...Read more

CrVI contaminated groundwater in the Mediterranean: Case study from Mersin, Turkey
(Corresponding) HATIPOGLU-BAGCI Z., BAYARI C., CANAKCI A.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
Increasing population, industrialization, agricultural and tourism activities in Mediterranean countries not only increase the water demand but also led to deterioration of water quality. Water quality degredation is a common problem in all circum-Mediterranean countries and there is an increasing...Read more
Recovery of rare earth elements from luminophores using the red alga Galdieria
Čížková M., Bišová K., Zachleder V., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic:
Electric and electronic waste
The red alga Galdieria phlegrea was used as an experimental organism to test bioaccumulation of rare earth elements (REEs) from luminophores. Algal cells were cultured mixotrophically in a liquid medium with addition of glycerol as a source of carbon. Luminophores from two different sources (...Read more

Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae
Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic:
Environmental biotechnology and bioenergy
Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...Read more

Research on the ability of urban trees to retain heavy metals. A silvicultural approach.
(Corresponding) Vordoglou M., Samara T., Tsitsoni T.
Topic:
Heavy metals in the environment
The purpose of the present research was to study the ability of urban trees’ leaves to retain heavy metals. Three major heavy traffic streets of Thessaloniki were chosen. Two tree species were studied: Ailanthus altissima (Mill.) Swingle and Catalpa bignonioides Walt. and 360 leaf samples were...Read more
Keywords:
urban trees, air pollution, heavy metals, morphology of leaf, silvicultural characteristics
The contribution of the cadaster to the protection of urban forests. The case study of Seich Sou.
(Corresponding) Vordoglou M., Samara T., Tsitsoni T.
Topic:
Spatial environmental planning
This paper studies the way in which modern land-forest map design contributes to the protection of urban forests generally and the Seich Sou urban forest of Thessaloniki in particular. We also examine the role of cadaster and forest maps in protecting urban forests from abuses such as pressure for...Read more

The influence of graphene addition on the properties of composite membranes RG / PAN and their potential application
(Corresponding) Fryczkowska B.
Topic:
Nanomaterials in the environmnents applications and effects
PAN is an inexpensive and popular engineering polymer, which is widely used in membrane techniques: ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) and pervaporation (PV). It is characterized by good thermal stability, high thermal conductivity, chemical resistance, solubility in...Read more
Conversion of coal fly ash by-products into high-grade zeolite by a quasi natural crystallization process
Zgureva D., (Corresponding) Boycheva S.
Topic:
Hazardous waste management
Recently, the synthesis of zeolites from coal fly ash (FA) has been extensively studied regarding the process optimization, industrial upscaling and technological commercialization. The obtaining of fly ash zeolites (FAZ) is based on the transformation of aluminosilicates of FA by alkaline...Read more
Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters
Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic:
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Magnetite nanoparticles activated coal fly ash zeolites with application in waste water remediation
(Corresponding) Boycheva S., Miteva S., Trendafilova I., Zgureva D., Václavíková M., Popova M.
Topic:
Wastewater treatment
The application of zeolites in wastewater treatment is studied long ago but still many unexploited opportunities exist. Recent investigations on natural and synthetic zeolites in water decontamination are focused on the improvement of their adsorption and ion-exchange properties modifying them by...Read more
