Dairy wastewater as growth substrate for biomass and biocompound production by Spirulina platensis
Escolà Oliva G., Zapata López D., Aristizábal Castrillón A., (Corresponding) Arroyave Quiceno C., Poschenrieder C., (Corresponding) Llugany Ollé M.
Topic:
Environmental biotechnology and bioenergy
Spirulina former Arthrospira is a Cyanobacteria with economic applications in agriculture, biofuel production and wastewater management. In order to evaluate the suitability of organic carbon containing wastewater for the production of biomass and biocompounds by Spirulina platensis (UTEX) strain...Read more

UV/H2O2 coupled with adsorption in the decolorization and phytotoxicity effects of dye mixtures
Ortega Tapia A., Alvarez Marroquin C., Cardona Rendón L., Arroyave Quiceno C., (Corresponding) Aristizábal Castrillón A.
Topic:
Advanced oxidation processes
UV/H2O2 is an effective process for the decolorization of dyes in water; However, after treatment if complete mineralization is not achieved the toxicity of the wastewater usually increases due to the generation of intermediated more toxic than the dye. Thus, a subsequent process to reduce toxicity...Read more
Evaluation phytotoxic effects and decolorization of simulated and real textile wastewaters by UV/H2O2
Quiceno Gómez L., Hernández Gallo M., Cardona Rendón L., Arroyave Quiceno C., (Corresponding) Aristizábal Castrillón A.
Topic:
Advanced oxidation processes
The discharge of dyes in aquatic ecosystems is of environmental concern due to intense coloration that decrease photosynthetic activity and the possible toxic effects (Hao et al., 2000). Therefore, the development and understanding of processes for the removal of textile dyes in wastewaters, like...Read more
Phase Diagram Modelling of a Multi-component Aqueous Solution of Katwe Salt Lake, Uganda
(Corresponding) Lwanyaga J., Kasedde H., Kirabira B.
Topic:
Desalination
A methodology is developed to compute the phase diagram of a hexary system and to determine the mineral precipitation sequence upon removal of water. The methodology is applied to construct the phase diagram and precipitation sequence of the system (〖Na〗^+,K^+)(〖Cl〗^-,〖SO〗_4^(2-),〖CO〗_3^(2-)...Read more
Neuro-, geno- and cytotoxicity responses in mussels Anodonta cygnea after six metals mixture treatment
(Corresponding) Butrimavičienė L.
Topic:
Heavy metals in the environment
Concerning toxicity, bioaccumulation and persistence in the aquatic environment, six metals such as Zn, Cu, Ni, Cr, Pb and Cd are attributed to priority hazardous substances in many countries throughout the world (Water Framework Directive 2008/105/EC; US EPA 2009). In this study, time-dependent...Read more
One-step Synthesis of TiO2/ZnO Nanocomposites by Refluxing Methods for Photochemical Degradation of Humic Acid
(Corresponding) Fadillah G., HIdayat R., (Corresponding) Wahyuningsih S.
Topic:
Nanomaterials in the environmnents applications and effects
Synthesis of TiO2/ZnO nanocomposites (TZN) through one-step refluxing method for photochemical degradation of humic acid (HA) in aqueous solution has been studied. Titanium isopropoxide (TTIP) and ZnSO4.7H2O were used as a starting material under base solution at 120 oC for 24 hours. TZN materials...Read more
Do Environment-related technologies strengthen the competitiveness of local systems?
De Noni I., Ganzaroli A., (Corresponding) Orsi L.
Topic:
Enviornmental data analysis and modelling
Environmental innovation is considered one of the key drivers of sustainable development and economic growth. However, we still know very little about the organizational factors underling the development of this category of innovations and their relative competitive effect. In this paper, we focus...Read more

Deciphering Coastal Vulnerability Index (CVI) for the coastal areas of Rhodes Island and the possible impact on tourism
(Corresponding) Vandarakis D., Loukaidi V., Kyriakou K., Kyriakidou C., Gad F., Sourianos E., Kapsimalis V., Drakopoulou P., Kikaki A., Hatiris G., (Corresponding) Panagiotopoulos I., Chatzinaki M., Morfis I., Sioulas A.
Topic:
Spatial environmental planning
Rhodes Island, located in the southeastern Aegean Archipelagos. Coastal areas, extended sandy beaches, people’s hospitality, and adequate infrastructure are principal factors that have increased the touristic value of the island. The estimation of the Coastal Vulnerability Index is important, since...Read more

Assessing the role of Posidonia banquettes in coastline protection against erosion, through UAV technology and granulometric analysis: Preliminary results from the case of Schinias-Marathon National Park, Attica, Greece.
(Corresponding) Vandarakis D., Salomidi M., Gerakaris V., Issaris Y., Kourliaftis I., Agaoglou C., Kapsimalis V., Panagiotopoulos I.
Topic:
Spatial environmental planning
Coastal environments and in particular beaches are valuable natural assets, offering a wide array of ecosystem services and economic benefits. In this study UAV technology with RTK-GPS is used in order to map in detail, the beach morphological characteristics, aiming to the impact of the presence...Read more
Comparative analysis of chlorinated intermediates formed during electrochemical and photo(electro)catalytic degradation of 4-Ethylphenol in saline media
(Corresponding) Brüninghoff R., van Duijne A., Braakhuis L., Saha P., Jeremiasse A., Mei B., (Corresponding) Mul G.
Topic:
Advanced oxidation processes
Formation of toxic by-products, such as chlorinated intermediates, is one of the major drawbacks of advanced oxidation processes for saline wastewater treatment. Here a comparative analysis of electrochemical oxidation and photocatalytic degradation of 4-Ethylphenol, a non-chlorinated starting...Read more
