Due to the lead content, the cathode ray tubes (CRTs) glass waste are considered a great environmental risk, as the lead ions from broken CRT glass can leach into soils when in contact with waters from landfills. Currently, the recycling techniques used for CRT glass are limited due to the different compositions of the panel, funnel and neck of the...

Pigments used in ceramic glazes have been obtained by chromium ions extraction from galvanic sludge and their precipitation as barium chromate and lead chromate from technological solutions. The chemical composition was determined by XRF method. Complex thermal analysis TG-DSC, XRD and SEM methods have been used for microstructural characterization...

Nutrient pollution, a growing problem for most European river basins, is a priority challenge in the Danube River Basin, a river that interconnects freshwater with the marine environment. The nutrient content of the Lower Danube waters in a river area where hydro-technical works to improve navigation conditions were carried out, respectively betwee...

Water is an important receptor of environmental problems generated by anthropogenic activities, the water quality being affected by their magnitude and impact as well as by climate change. Given the international and cross-border nature of the Danube River and being aware that the pollution risk assessment is one of the key elements of the ecology...

Twenty-two groundwater sources mainly used for drinking purpose in Bucharest peri-urban area were investigated for assessment of physico-chemical and microbiological quality with a view to determining its potential risk to public health. Results of chemical analysis revealed that nitrites, sulphates and chlorides were below the permissible levels,...

Landfilling of end-of-life CRT (cathode ray tube), from computers and other electric or electronic equipment, is an emerging environmental issue which require immediate actions. CRT glass waste represents over 50% of the weight of WEEE (Waste Electrical and Electronic Equipment). However, recycling techniques for CRT glass represent a major problem...

Biological filters are wastewater treatment systems that contain a granular filling material, which form an active biological film that contribute to the biooxidation of impurities from the wastewater. Recent research in the field aimed to improve the classical treatment facilities with aerobic fixed film by using inexpensive and easily accessible...

This paper attempts to determinate the optimal tilt angle and azimuth angle of an 100 kW photovoltaic power plant for a Bucharest region. Simulations were made with PVsyst V6.39 for south-east orientation (100; 450) and south-west orientation (100; 450), for the tilt angle the simulations were made at 100, 150, 370, 600 and 900. The simulation on 1...

The concept of glass waste has been re-evaluated by the European Commission, thus, glass waste is considered a secondary raw material, according to EU Regulation 1179/2012. In 2014, 18.5 million tonnes of glass were generated at EU level, from which only 123.768 tonnes in Romania. The glass waste generation indicator shows that plastic packaging an...

INTRODUCTION This paper presents the results of the research activity in order to establish the stability and leaching potential of ceramic tiles which have been developed using glazes colored with pigments obtained by the extraction of chromium and iron metals from electroplating sludge. Emissions of toxic substances from the decoration and glaze...

This study aims to investigate the chemical attack of a binder material with a 20% hydraulic active powder content (ceramic brick powder) and a water / binder ratio of 0.45. Additionally, considering the potential applications of prefabricated binder materials incorporating different types of wastes, with / without hazardous substances, the impact...

This paper presents the results of the research activity in order to etablish the stability and leaching potential of ceramic tiles which have been developed using glazes colored with pigments obtained by the extraction of chromium and iron metals from electroplating sludge. All these ceramic tiles contain various amounts of heavy metals in their g...

Abstract. Electroplating sludge resulting from wastewater (washing wastewater and technological solutions) treatment is considered to be a hazardous waste, a mixture of hydroxides of the many heavy metals such us: iron, chromium, copper, nickel, cadmium or zinc. The metal compounds from electroplating sludge have a great economic value, thus, a num...

The purpose of this paper is the experimental analysis of the thermoelectric power plant Grozavesti impact on Bucharest urban agglomeration for year 2015. Experimental research is done for the NOx and SO2 pollutant for all seasons. The thermoelectric power plant Grozavesti is located near the Botanical Garden. Data provided by the industrial source...

Noxious agents released into the atmosphere that can cause harmful effects on human health and environment are often in the form of a complex of toxic substances in which both solid and gas particles are present. Polluting elements do not remain at the sources where they are produced, but due to influential factors, they are propagated to significa...

The issue of hazardous industrial waste has always represented a challenge for both waste generators and researchers. The need to decrease the amount of industrial waste, impose a clear and firm strategy of re-use, to the detriment of disposal, under hazardous conditions for the environment and human health, most of the times. The galvanic sludge r...

Contribution to the strengthening of the bilateral cooperation between Romania and Norway, linked to improvement of knowledge and capacity of a number of experts and professionals in hazardous substances, by means of professional training: TARCHS PROJECT

This paper addresses the assessment of the Danube River water monitoring data obtained for the nutrients in the period 2013-2014 in order to achieve and/or maintain the environmental of the river for January-December period of each year in line with the provision of the Government elements of quality: N-NH 4 + , N-NO 2-, N-NO 3-, P-PO 4 3-, P t. Si...

Some of the hazardous industrial waste proved to be an important source of secondary raw material with economic value. One of the potentially recoverable materials is the galvanic sludge. A possibility to recover heavy metal ions from galvanic sludge consists in using of their extracted oxides or hydroxides in ceramic glazes. This paper reports the...
