This work deals with the removal of lead, copper and zinc from aqueous solutions by using natural zeolite (clinoptilolite). Fixed bed experiments were performed, using three different volumetric flow rates of 5, 7 and 10bed volume/h, under a total normality of 0.01N, at initial pH of 4 and ambient temperature (25 degrees C). The removal efficiency increased(More)
Mobile business research has arguably grown to become one of the most topical and complex eBusiness research areas in recent years. As a result, researchers face a plethora of interdisciplinary research challenges. Understanding the range of these challenges and confronting them requires coordinated research efforts, backed up by a holistic guiding(More)
This paper refers to the management of the construction and demolition (C&D) waste since, according to the EU Waste Strategy, C&D waste is considered to be one of the priority waste streams and appropriate actions need to be taken with respect to its effective management. Initially, the paper presents the state-of-the-art of the problem of C&D waste,(More)
— Enhanced UMTS traffic generation and activity models are described and characterised, based on population and service penetration values. An offices scenario was defined with a selection of relevant applications. ON/OFF states have been characterised by appropriate statistical distributions, and parameters for source traffic modelling have been presented.(More)
Future Communication Networks are envisioned to be based upon a common, flexible and scalable convergence platform, where different access networks, different terminals and different services can coexist. The new user capabilities spawn a demand for Always Best Connectivity (ABC), i.e. that a user can always have the best possible connection regardless of(More)
Within the European Union, guidance in the form of a uniform Soil Directive does not exist and member states are left to enact their own legislation governing historic soil contamination. Several historic or "legacy" sites exist in Cyprus - an EU member state with a long history of mining and a significant number of abandoned mining sites. The gold-silver(More)
Surfactants offer two mechanisms for recovering NAPLs: 1) to mobilize NAPL by reducing NAPL/water interfacial tension, and; 2) to increase the NAPL's aqueous solubility-called solubilization-as an enhancement to pump & treat. The second approach has been well-studied and applied successfully in several pilot-scale and a few full-scale tests within the last(More)
The aim of this study is to investigate ammonium removal from a wastewater resulted after homogenization and anaerobic digestion of a mixture of wastes and wastewater from animal processing units and sewage sludge, by using natural zeolite clinoptilolite. Batches as well as closed loop fixed bed system (CLFB) are studied, offering an alternative to(More)
The aim of this work is to examine copper removal from sludge permeate with the use of low-cost minerals of Mediterranean origin combined with ultrafiltration membranes. The minerals used were zeolite (clinoptilolite), bentonite and vermiculite. Activated sludge was enriched with 0.01 N (317.7 ppm) of Cu(II). Fixed concentrations of minerals were added to(More)
