HEAVY METALS TRANSPORT FROM WASTEWATER SPILLS INTO A COASTAL AQUIFER AND SEAWATER
Environmental Engineering and Management Journal › Vol. 18 › Nr. 12 Wastewater generated from industrial activities has delivered elevated heavy metal concentrations into fresh and salted aqueous systems. Herein, the migrated trace metals were studied from their initial location through a coastal aquifer up to the seawater. The experiments were carried out at lab scale using a sandbox with glass beads and two attached chambers containing natural groundwater and seawater. The study focused on the transport behaviour of heavy metals such as copper, zinc and lead i... Autori: Abdelkader Tawfeek Ahmed ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28111
RECYCLING OF LIGHT-EMITTING DIODE WASTE QUARTZ SAND ACTING AS A POZZOLANIC MATERIAL FOR PORTLAND CEMENT
Environmental Engineering and Management Journal › Vol. 19 › Nr. 5 LED waste quartz sand (LEDWS), which is a prominent by product of the LED manufacturing process, may contaminate the environment because it comprises specific heavy metals (e.g., As and Cu), which are hazardous ingredients to the environment when disposed of improperly. Therefore, this study investigated the use of light-emitting diode (LED) waste quartz sand to partially replace Portland Type I cement (OPC) to evaluate the feasibility of reusing it as a pozzolanic material. The SiO2, Na2O, and ... Autori: Kae-Long Lin ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28207
PERMEABILITY MUTATION MECHANISM OF HYDROGEOCHEMICAL CONDITIONS IN SEA AND FRESHWATER TRANSITIONAL ZONE
Environmental Engineering and Management Journal › Vol. 19 › Nr. 9 Taking the sandy aquifer intruded by seawater in the lower reaches of Dagu River as the research object, the samples of underground freshwater, seawater and aquifer media were collected, and their composition and properties were determined. The seepage device was used to simulate the displacement process of seawater and freshwater. The relationship between permeability change of aquifer and hydrologic-geochemical action was studied. The mechanism of water sensitivity was explained by a hydrologi... Autori: Jiaguo Ren ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28281
SFS-H PHYTOTREATMENT OXI-NITRO RATE TESTED IN STEADY-STATE ON ENGINEERING-UNIBO PILOT PLANT
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Natural wastewater treatment systems can represent a smart solution in small communities (50-2000 Population Equivalent) as they are very low-cost technologies in terms of energy consumption and maintenance. Moreover, those systems could be implemented as clean processes for wastewater reuse in the frame of circular economy applications. In this context the present study examines the main features of Subsurface Flow System - horizontal (SFS-H) phyto-treatment process. To this aim a pilot plant w...

UTAQ, A TOOL TO MANAGE THE SEVERE AIR POLLUTION EPISODES
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 The Urban Tool for Air Quality (UTAQ) is a project funded by CAMS (Copernicus Atmosphere Monitoring Service) - ECMWF (European Centre for Medium-Range Weather Forecasts). UTAQ is a web-based tool with a user-friendly interface that allows users
to evaluate current and forecasted air quality for the following 4 days at urban scale with high resolution (10-50 m). UTAQ, in the mobile version, allows citizens to evaluate and then to limit their air quality exposition thanks to the personal position...
