UN(K)NOWN Project: Development of Anammox microbial inocula to improve nitrogen removal efficiency in wastewater treatment

(Corresponding) Ribeiro H., Machado A., Costa-Dias S., Wijaya I., Salgado P., Bordalo A., Teixeira C.
Topic: 
Wastewater treatment
The discovery of anaerobic ammonium oxidation (anammox) revealed the existence of a shortcut in the classic nitrogen cycle where ammonium is converted directly to dinitrogen gas. Anammox process can be used to develop more cost and energy-efficient sustainable nitrogen removal systems comparing to...Read more

Start-up of the nitrogen removal process in an anaerobic up-flow reactor inoculated with aeration tank sludge

Wijaya I., (Corresponding) Ribeiro H., Soedjono E., Slamet ., Teixeira C., Bordalo A.
Topic: 
Wastewater treatment
Anaerobic ammonium oxidation (anammox) has been considered a promisingly alternative to traditional nitrification/denitrification to remove nitrogen in an autotrophic process, without using an external carbon source, requiring low energy consumption and sludge production. The start-up of the...Read more

Catalytic Pyrolysis of Plum Seed

(Corresponding) Pehlivan E.
Topic: 
Energy technologies and sustainability
In this study, pyrolysis and catalytic pyrolysis of the plum seed was investigated. For this purpose, the characteristics of the raw materials were determined by proximate analysis (moisture, ash, volatile matter, fixed carbon), structural analysis (holocellulose, hemicellulose, hemicellulose,...Read more

Stakeholder Participation in Prioritization of Water Supply and Demand in Jordan

(Corresponding) Shammout M., Shatanawi M.
Topic: 
Efficient water resources management in cr(vi) impacted water bodies
Stakeholder participation in prioritization of water supply and demand was developed to assist water resource entities and water users on decision making when coping with water scarcity, climate change and contaminated water in Zarqa River Basin, Jordan. The basin was selected for CrITERIA project...Read more

Acid generation and heavy metal leachability from waste lignite disposal sites, Oropos basin, North Attica. An assessment on preliminary data

Kampouroglou E., Kollias K., (Corresponding) Stouraiti C., Papassiopi N.
Topic: 
Heavy metals in the environment
Lignite mining in the Oropos Neogene basin (North Attica), especially in the areas of Milesi and Markopoulo, operated since last century and ceased in the late 1960’s. Piles of complex waste material consisting of lignite tailings and waste rocks are dispersed in the area between the above...Read more

A novel types of compound for surface treatment of carbon nanotubes for more effective application in polymers

(Corresponding) Hangyási K., Varga C., Nagy R., Simon-Stőger L.
Topic: 
Green chemistry
Nowadays, beneficial management of plastic and rubber waste from different sources and environmentally friendly ways of recycling is becoming an increasing challenge. A possible solution for that issue could be to produce plastic composites usually consisting of heterogeneous phases. That fact and...Read more

Fuzzy Relation Between The RDIst Index And The Water Table Of A Coastal Aquifer of Nestos Delta, Greece

(Corresponding) Papadopoulos C., Gkiougkis I., Spiliotis M., Pliakas F., Papadopoulos B.
Topic: 
Floods, droughts and water scarcity
Drought is a complicated natural extreme event associated with the decline of water availability below the normal conditions of a hydrological system, both from a temporal and from a spatial point of view. This work aims to assess the drought impacts on groundwater fluctuation in a shallow coastal...Read more

A DPSIR approach to selected Cr(VI) impacted groundwater bodies within Attica and Eastern Sterea Ellada River Basin Districts

(Corresponding) Pyrgaki K., Argyraki A., Kelepertzis E., Botsou F., Megremi I., Karavoltsos S., Mpouras A., Dassenakis M., Hatzaki M., Dermatas D.
Topic: 
Efficient water resources management in cr(vi) impacted water bodies
The holistic approach of the Driver-Pressure-State-Impact-Response (DPSIR) analytical framework in combination with Geographical Information Systems was applied to selected Cr(VI) impacted groundwater bodies. For the characterization of “state”, 157 samples including field blanks were collected...Read more

Reduction of Halogenated Organic Compounds in Water: Comparison of Available Reduction Systems based on Cu, Pd and ZVI

(Corresponding) Shee A., Kopinke F., Mackenzie K.
Topic: 
Water treatment
Catalysts on the basis of copper (Cu) and the reducing agent borohydride (BH4-) have been successfully used for reduction of chlorinated aliphatics with low substitution degree which are usually resistant to zero-valent iron (ZVI) and hydrodehalogenation catalysts, such as Pd. Reactivity screening...Read more

Membrane Distillation Treating a Petrochemical Reverse Osmosis Concentrate

(Corresponding) Venzke C., Giacobbo A., Rodrigues M., Bernardes A.
Topic: 
Wastewater treatment
This study investigated the applicability of Direct Contact Membrane Distillation (DCMD) process for the treatment of a petrochemical industry effluent, intending to recover water from the concentrate produced by reverse osmosis (RO). In DCMD, the experiments were accomplished with a feed and...Read more
