Production of low aromatics and low sulfur diesel in a hydrodesulfurization (HDS) pilot plant unit
General
The present work investigates the hydrotreating process of a diesel in order to achieve lower sulphur and aromatics content. The entire work was performed in a Hydrodesulphurization (HDS) pilot plant unit located in Chemical Process Engineering Research Institute (CPERI). For the tests, a commercial...
Life Cycle Assessment (LCA) in Business. An overview on drivers, applications, issues and future perspectives.
General
In recent years, a considerable research effort has been devoted to Life-Cycle Assessment (LCA). However, most of the work has been focusing on improving the methodology as such and providing guidelines for carrying out LCA studies. Much less effort has been dedicated to the exploration and analysis...
Soil adsorption behaviour and photomineralization by photocatalytic membranes immobilizing titanium dioxide of atrazine and intermediates
General
The soil adsorption behaviour of atrazine and its photodegradation intermediate 4,6-diamino-2-chloro-1,3,5- s-triazine (I), was evaluated by measuring partition coefficients on five representative European topsoils using classical batch experiments. From this study, (I) appears to be less...
A method for assessing soil vapor intrusion from petroleum release sites: Multi-phase/multi-fraction partitioning
General
A model and spreadsheet-based numeric approximation for computing risk-based soil cleanup level to be protective of petroleum-contaminated soil to an indoor air exposure pathway is presented. The algorithm incorporates traditional equilibrium partitioning equations (3 or 4-phase) for the...
Estimation of secondary organic aerosol (SOA) production from traffic from the city of Athens
General
Estimates of the amount of secondary organic aerosol formed in the atmosphere from the degradation of traffic C6-C12 hydrocarbon emissions in the city of Athens are presented. Around 1.26 tn of organic aerosol is estimated to be produced during a six hours air pollution episode from the aromatic...
Economic incentives in sustainable water management: a Risk-Based Decision Analysis approach for determining groundwater pollution charges under uncertainty
General
A risk-based decision analysis methodology is presented, that can be used as a water policy tool in the design of economic incentive instruments, under conditions of uncertainty. A contaminated groundwater resource system with unknown hydrogeological parameters is used as a case study. The polluter...
Toxic effects of Atrazine, Deethyl-Atrazine, Deisopropyl-Atrazine and Metolachlor on Chlorella fusca var fusca
General
The toxic effects of the herbicide Atrazine, its degradation products deethyl-atrazine and deisopropylatrazine, and the herbicide metolachlor were examined in unialgal cultures of Chlorella fusca var-fusca. The toxicity of a mixture of atrazine and metolachlor was also evaluated using the same...
Environmental policies and natural resource management in Southeast Asia - Contemporary Issues
General
Recently, environmental issues have become a priority in the agenda of ASEAN countries due to the serious impacts of environmental degradation. Similar to other countries, ASEAN countries have their own strengths and weaknesses in environmental protection, which depend on their policies and law...
Ammonia and Phosphorous removal in municipal wastewater treatment plant with extended aeration.
General
Samples were taken from Metamorphosis/Attica combined treatment plant for municipal wastewater and septage, which treats about 12000 m3 d-1 of municipal wastewater and 8000 m3 d-1 of septage, and analyzed for solids, COD, ammonia, nitrate, orthophosphate, polyphosphate and total phosphorus. Ammonia...
Photocatalytic treatment of Olive Milling waste water: Oxidation of protocatechuic acid
General
The photocatalytic degradation of protocatechuic acid, a biorecalcitrant polyphenolic compound typically found in olive processing and wine distillery waste waters, has been investigated in aqueous heterogeneous solutions containing semiconductor powders (TiO2, ZnO) as photocatalysts, both in the...
