Paraschos Melidis and Georgios Sylaios, researchers at the Democritus University of Thrace (DUTH), Greece, which is part of the Mare Nostrum Project, are presenting a new research at the 9th World Congress of the European Water Resources Association (EWRA) being held in Istanbul, June 10-13, 2015.
Within the framework of the Mare Nostrum Project, Melidis and Sylaios did research on “Assessment of pollutant loadings from wastewater treatment plants (WWTPs) in Kavala Gulf”.
In their research, Melidis and Sylaios found that although pollutant concentrations in the Gulf of Kavala are technically low, large amounts are constantly flowing into the water body at a rate high enough to contribute “significantly” to increased water pollution and alter the Gulf’s benthic system.
“Reduction of the discharged volumes could be achieved through reclaiming wastewater,” the researchers argued, and reusing it for industrial needs within the plant, watering urban and suburban green areas, as well as for groves and forests, firefighting systems, street cleaning, and irrigation for agriculture and other landscapes.
Melidis and Sylaios concluded that “Proper reusing of effluent discharges from WWTP’s should lessen the environmental impacts at the coastal water regarding the suspended solids, organic matter, nutrients, heavy metals and micro pollutants.”
Around the world, pollution and other impacts of large population concentrations negatively affect coastal waters, the researchers noted. “Population increases in these areas produce large volumes of discharged domestic and industrial wastewater, considered as one of the major significant stresses impacting the coastal environments,” they said.
For the study of the current water quality situation in the Gulf of Kavala, Melidis and Sylaios focused on analyses of systematic pollution indicators, including carbonaceous materials, suspended solids, and nutrient time-series. “The data sets used are long-term, relatively consistent, and available [to the] public,” they noted.
Melidis and Sylaios will present their research at the “Water Pollution and Eco-systems Conservancy” conference within the Istanbul EWRA world congress, which will focus on pollution sources and management, protection of ecosystems, water quality and health of aquatic systems, waste management, efficient water use and recycling, regulation, and more.
The remaining five conferences within the EWRA world congress focus on Hydrological Processes and Evolving Hazards; Geo-information and Water Resources; Technological Advances in Water Distribution, Purification and Desalination; Multicriteria Sustainability of Water Systems; and Social, Political, Institutional and Legislative Aspects. Each conference in turn comprises two parallel sessions.Leave a reply →
