Potential of Using real-time OiW monitoring for control of produced water treatment in offshore oil & gas production
(Corresponding) Zhenyu Y.
Topic:
Water treatment
The produced water has been the largest produced fluid stream at most of the current offshore oil & gas production in North-sea. It is not uncommon that the water cut can reach 90% in many matured production fields. No matter the produced water will be eventually discharged to the ocean, or...Read more

Putting accelerated carbonation of bottom ash into practice: operation of a semi full scale continuously fed rotating drum reactor
Brück F., Schnabel K., (Corresponding) Weigand H.
Topic:
Hazardous waste management
Bottom ash is the dominant residue from municipal solid waste or refuse-derived fuel incineration. Disposal costs chiefly depend on the leachability of trace metals and salts. The mobility of these constituents is classically minimized by ageing the material for several months. Ageing involves the...Read more
Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe2+]0=0-100.0 mg L-1, using oxidant ratios of [H2O2]0=250.0 mM. The oxidation...Read more
Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The oxidizing action of hydrogen peroxide was studied in a range between [H2O2]0=0-250.0 mM, using iron ratios of 0.7 mol Fe2+/mol C8H10N4O2...Read more
Changes of dissolved oxygen during the caffeine oxidation by photo-Fenton
Villota N., (Corresponding) Lomas J., (Corresponding) Irene C.
Topic:
Advanced oxidation processes
The aim of this work is to analyse the changes of dissolved oxygen ([DO], mg/L) during the oxidation of caffeine waters by photo-Fenton treatment. The concentration of dosed hydrogen peroxide would be the addition of the stoichiometric [H2O2], which reacts with organic matter ([H2O2]esteq=2.0 mM),...Read more
From system concept to serious game: the SIM4NEXUS approach to policy-relevant nexus research
(Corresponding) Susnik J., Masia S., Khoury M., Vamvakeridou-Lyroudia L., Brouwer F., Riegels N., Domingo X., Lluis E., Evans B., Savic D.
Topic:
Water, energy and/or food nexus
There is growing interest in using serious games for a wide range of applications, from water resources management, to surgery simulations, to pilot training. At the same time, there is rapidly growing interest in the water-energy-food/land-climate nexus, where interactions in one sector can lead...Read more
A system dynamics model to explore the water-land-energy-food-climate nexus in Latvia
Masia S., (Corresponding) Susnik J., Indriksone D., Bremere I., Vamvakeridou-Lyroudia L., Brouwer F.
Topic:
Water, energy and/or food nexus
Water, energy, food/land use and climate are connected a system defined by complexity, feedback and delay, and are commonly referred to as the nexus which operates across scales. Therefore the characteristics of the nexus change depending on the scale being considered, the location, and the sectors...Read more

“The adverse Health effects of non ionizing radiation on foetus and child: is a mythos or a scientifically evident global public health challenge”
(Corresponding) Canna Michaelidou S.
Topic:
The non ionizing radiation from wireless technology: a 21 century revolution or a global pollution and health hazard
Exposure to EMF/RF is continuous, multiple, exponentially growing, affecting entire population actively and passively. Children because of wireless-enabled devices are continuously exposed. Potential health Impacts include oxidative stress, carcinogenicity, developmental neurotoxicity, effects on...Read more

Colour changes during the carbamazepine oxidation by photo-Fenton
Villota N., (Corresponding) Qullatein H., (Corresponding) Lomas J.
Topic:
Advanced oxidation processes
Oxidation of waters containing 50.0 mg L-1 of carbamazepine was conducted by a photo-Fenton reagent employing a UV lamp of 150W, at pH=3.0 and T=40°C. The oxidising action of hydrogen peroxide was studied in a range between [H2O2]0=0-15.0 mM. When applying stoichiometric ratios of 2 mol C15H12N2O:...Read more
Dynamic heat map as a part of the regional energy transition
Wern B., (Corresponding) Noll F., (Corresponding) Baur F.
Topic:
Spatial environmental planning
Heat maps show the heat and cold demand of residential, commercial and industrial buildings as well as the waste heat from industry. They combine these two aspects in order to plan new heating/cooling grids. By planning the thermal energy supply in a central way, the efficiency of the energy...Read more
