Super Absorbent Polymers in Environmental Remediation
General
Laboratory studies reported earlier, have shown very promising results in the selective removal of dyes from aqueous solutions by a commercially available (super absorbent polymer) SAP, Jalshakti® (JS). JS is mesoporous in nature and is a potential adsorbent for the basic dyes studied. This paper...
Stabilization/Solidification (S/S) Pb and W Contaminated Soils using Type I/II Portland Cement, Silica Fume Cement and Cement Kiln Dust
General
Stabilization/solidification (S/S) processes were utilized to immobilize lead (Pb) and tungsten (W) in contaminated soils, the inclusion of W motivated by the use of the new W-based ammunition. Artificially contaminated soils were prepared by mixing either kaolinite or montmorillonite with 10% Pb...
Rehabilitation of abandoned saltworks to maximize conservation, ecotourism and water treatment potential
General
Numerous saltworks have been abandoned throughout the Greek islands and mainland as operations have decreased in number and increased in size. Such areas have great potential for serving the broader society if rehabilitated correctly. Changes in landscape uses recently, especially agricultural...
Treatment of distillery spent wash by combined UF and RO processes
General
The present study deals with the treatment of distillery spent wash by an ultrafiltration (UF) membrane followed by reverse osmosis (RO) membrane on a pilot scale membrane setup. The performance of the system was evaluated by varying applied pressure on the thin-film composite polyamide (TFC-PA) UF...
Investigation of the Annual Variability of the Aleppo Pine Tree-Rings Width: the Relationships with the Climatic Conditions in the Attica Basin
General
The relationships between the annual variability of the Aleppo pine tree-ring widths and the variability of the main climatic parameters in the Attica basin are analysed in the present study for a 45-year period (1959-2003). The Principal Components Analysis was applied to the times-series of the...
Secovlje Salina Nature Park, Slovenia – new business model for preservation of wetlands at risk
General
Ecological management plan and its implementation for particular wetland are highly dependent on securing effective management tools, including management according to the management plan. The implementation of such a plan requires adequate resources, both in terms of human and financial support...
Production of copper powder form printed circuit boards by electrodeposition
General
During the last years, the waste electrical and electronic equipment (WEEE) are gathering attention, as a very special section of waste. In fact, they have been proven to be source for the recovery of metals. In the present study printed circuit boards (PCBs) were cut and treated thermally at 500oC...
A novel tool for estimating the odour emissions of composting plants in air pollution management
General
Odour emissions are a major environmental issue in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time...
The promotion of salt quality through optimizing brine concentration a new technique “bidirectional brine concentration”
General
The commonly accepted brine concentration practice in most Chinese Northern solar works is to pump the sea water into salt works and then let it go through a physical changing process of natural evaporation, condensation and crystallization, during which, weather factor and the soil nature have to...
Use of simulation models in the protection of groundwater aquifer systems. Application at the Upper Anthemountas basin in Chalkidiki, Greece
General
The importance of the development and application of groundwater simulation mathematical models in the protection of aquifer systems is nowadays recognised as an undisputable fact. In this paper a mathematical model that was developed in order to simulate the operation of the Upper Anthemountas...
