Abstract Waste management hierarchy has as priorities waste recycling and energy recovery. Unfortunately, Romania is in the situation so as the waste landfilling is still considered as a suitable solution for waste management. European Union imposed a number of regulations and programs in the field of waste treatment and management that Romania must comply. The paper describes some aspects regarding characterization of the leachate originating from the Tomesti landfill (situated in Iasi County...

AbstractThe reuse of a wastewater treatment system was investigated using intermittent media infiltration (IMI) to evaluate the fecalcoliform (FC) removal efficiency with natural zeolite containing clinoptilolite from the state of San Luis Potosí, Mexico and itszinc-modified form (Zeo-Zn). The municipal wastewater, which was from Saltillo, Coahuila, Mexico, was treated for FC analysisfor four months. The physicochemical properties of zeolite were analyzed, and their behavior as filter media for ...

AbstractWorldwide, waste materials are produced as a by-product of industrial manufacturing and placed in storage areas. One of the waste materials is filter cake (FC). FC is formed during the infiltration of cooling water in steel factories. The main aim of this research is determination of optimum usage of FC in the production of impermeable layer on ground by using fuzzy model approach. Because of this, in the study, FC as a waste material was hardened with cement and an impermeable layer was...

AbstractThe study site is located on South of Bacau City, Romania, on two water courses: the Siret River – the branch flowing throughthe old riverbed downstream Galbeni Reservoir, and one of its tributaries - an infiltration channel, both of them being used by thelocals for fishing and irrigation, and the common meadow for grazing. The study covers the right side of the Siret River, betweenthe interception point up to Galbeni Reservoir dam and the equivalent length of the infiltration channel. T...

Abstract In Hungary, 0.5 million m3 of thermal water is exploited every day for diverse purposes. After utilization, this enormous amount of thermal water becomes sewage water with a high concentration of salts, heavy metals, ammonia, nitrate, an unfavorable ion composition and high temperature. A common treatment is to dispose of waste water into a surface recipient through uninsulated channels surrounded by arable land. By infiltration, sewage water can cause potential salinization/sodific...

Abstract The Bio.Lea.R project aims to demonstrate the performance of a landfill for less reactive, biologically treated waste (pretreated organic wastes) compared to a conventionally managed landfill, with regard to both environmental (biogas and leachate production) and economic aspects. The objective is to control the pretreated biodegradable waste through a liquid injection in order to achieve the same biogas quantity in a shorter time than in conventional landfill. Laboratory and full ...

Abstract A new assessment method of groundwater vulnerability was done using multilayer data analysis through GIS Spatial Analyst Tools. The method presented here refers at Beliș district territory and describes two tasks: (1) groundwater vulnerability determination from Water Surplus, Ecosystem Services, Aquifers map, and Infiltration map; (2) the future vulnerability assessment for 2050, considering four scenarios of land cover and climate data changes. First results, carried out by p...

Water scarcity, the degradation of freshwater resources, and wastewater pollution are reaching crisis levels, especially in arid regions of the world. The reuse of wastewater was investigated by using intermittent media infiltration (IMI) to evaluate fecal coliform (FC) removal efficiency. Twelve IMI columns were packed with soil and natural filtering materials (sand, zeolite, vermicompost and charcoal) at percentages of 25, 50 and 75. The municipal wastewater was treated for the FC analysis ...

This study presents the results obtained in tailoring thin films of alumina, deposited onto aluminium substrates by spray pyrolysis, at 250°C, using AlCl3 solutions (0.15M) in a water:ethanol (1:1) solvent mixture. As morphology controlling agents, acetylacetone and maleic acid based copolymers are added in the precursors’ solutions. The precursors’ systems are analyzed by FTIR spectroscopy and the surface morphology of alumina thin films is investigated by atomic force microscop...

Urban water-logging disasters are induced by multiple causes, such as land use structure, limited capacity of drainage system, climate change and lack of enforcement. Significant increase of impervious surface area is the main cause of urban water-logging disaster in big cities like Beijing. This article takes Beijing “7.21” storm and New York hurricane “Sandy” as examples, and explains the cause of urban water-logging from the perspective of land use structure. In this s...

The research work aimed at analysing the drinking water quality in Vilanculos (Mozambique) and at investigating the influence of poor sanitation management on drinking water quality. The purpose was to understand the reasons of water source contamination and re-contamination in the water supply chain, in order to define strategies to control source contamination and to suggest practical ways for reducing the risk of recontamination. A first phase of microbiological drinking water quality monito...

Leachate production and management are recognized as one of the greatest problems associated with environmentally operations for landfills. Variations in leachate quality and quantity are related to rainfall depth and its infiltration processes into landfill. This work examines important hydrological problems of the Scarpino site (Genoa, northern Italy), a garbage dump which covers the valley of a first order flash creek with a surface of 100 hectares, located in one of the rainiest area of Ita...

The current trends in Mediterranean climate indicate longer periods of drought and hot temperature in summer and shorter and more intense precipitation in spring and autumn, which require reconsidering the current water management. The Emilia-Romagna coastal area (Northeastern Adriatic Sea, Italy) is entirely drained by a network of channels connected to more than 70 water pumping stations. Although drainage is fundamental in wet periods to keep the land dry, during long periods of stable wea...

Slags are the main by-products from steelmaking cycle, which are currently recycled inside the steel industry as well as in other sectors with significant environmental and economic benefits. As in Italy slags application is not yet allowed in agriculture, the paper aims at evaluating the technical and economic feasibility of a slag treatment plant, to obtain a product to be sold in the fertilizer market as soil amendment. A preliminary assessment of the fate of some trace metals (Cr, V, Sb a...

This article addresses CO2 dynamics in school classrooms and analyses the improvement of ventilation and indoor air quality resulting from the simple window-opening ventilation strategies. CO2, temperature and relative humidity were measured in four different naturally ventilated classrooms of a Northeastern Portuguese education institution for a wide range of environmental conditions. Indoor CO2 levels were also simulated with a numerical model to help manage the indoor air quality of these ...
