Geographic Information System-Based Tools In Environmental Management, Zeinab Bedri, Michael Bruen

Articles

The authors reviewed existing modelling platforms as part of a large study of water and pollution pathways through catchments in Ireland (Irish EPA Pathways project). Worldwide, work on producing catchment management tools (CMTs) has been underway for some time and some of the tools identified here date from as early as 1989. Some of the management problems and model conceptualisations have not changed very much but now there is a stronger emphasis on water quality and more concern about a wider range of contaminants. What has changed substantially is the use of Geographical Information System and Graphical Windows interfaces as …

A Quantitative Analysis Of The Impact Of Wind Energy Penetration On Electricity Prices In Ireland, Micheal O'Flaherty, Niall Riordan, Noel O'Neill, Ciara Ahern

Articles

The maturity of wind technology combined with availability of suitable sites means Ireland is on course to generate 40% of its electricity from the wind by 2020.This work sets out to quantify, to what degree, if any, increased wind penetration translates into reduced wholesale and retail prices for electricity. The consensus from the literature is that increasing wind penetration reduces wholesale electricity prices, but views vary as to what degree this translates into reduced retail prices for the consumer.

This work demonstrates the effect of wind energy penetration on the price of electricity in Ireland using quantitative data from the …

Experimental Design Of Photo-Fenton Reactions For The Treatment Of Car Wash Wastewater Effluents By Response Surface Methodological Analysis, Maha Tony, Zeinab Bedri

Articles

Establishing a treatment process for practical and economic disposal of car wash wastewater has become an urgent environmental concern. Photo-Fenton’s process as one of the advanced oxidation processes is a potentially useful oxidation process in treating such wastewater. Lab-scale experiments with UV source, coupled with Fenton’s reagent, showed that hydrocarbon oil is degradable through such a process. The feasibility of photo-Fenton’s process to treat wastewater from a car wash is investigated in the present study. A factorial design based on the response surface methodology was applied to optimize the photo-Fenton oxidation process conditions using chemical oxygen demand (COD) reduction as …
