Most of water sources throughout the world contain natural organic matter (NOM), which is the best description as a complex mixture of organic compounds. The effect of iron ion on removal efficiency of dissolved organic carbon (DOC) using UV/TiO 2 photo catalytic oxidation (TiO 2) was examined. In...

The main objective of this study was to investigate the differences between the main pollutants in young and intermediate age landfill leachate in terms of molecular weight distribution (MWD). Parameters of chemical oxygen demand (COD), five day - biochemical oxygen demand (BOD 5), ultraviolet...

This paper reports on the fabrication, characterization and testing of iron oxide nanoparticles – powdered activated carbon (PAC) composites for water treatment and PAC regeneration by Fenton reactions. Different wet impregnation procedures and iron loadings were assessed in terms of organic...

It is well known that chlorine and its compounds, traditionally utilized for water and wastewater disinfection, react with some organic matter to form undesirable by-products, hazardous to human health, known as Disinfection By-Products (DBPs). In many countries very stringent limits for...

This study investigates the effect of different pre-treatments on the bio-ethanol production from the soluble compounds of the organic fraction of the municipal solid wastes (OFMSW). The experimental evaluation was performed on leachate samples obtained after mixing OFMSW with water during 10 d. The...

Several adsorbents have been tried out by researchers to remove different pollutants from wastewater. However, the adverse effect of these biosorbents on the treated water and the possibility of leaching new pollutants to the treated water have not been investigated. A batch technique was employed...

The use of organic manures as amendments to improve soil organic matter level and long term soil fertility and productivity is gaining importance. The disposal of the great quantity of organic wastes produced by the municipal, agricultural and agroindustrial activities, is causing energetic...

3,4-dichloroaniline (3,4-DCA) is a hardly biodegradable and hydrolysable compound, characterized as a persistent pollutant for water, soil and sediment and highly toxic for living organisms. In this work, the impact of different micrometeorological conditions on uptake of 3,4-DCA was investigated in...

A considerable number of diseases are directly related to environmental impact. Toxic metals such as Hg, Pb, Cd, and As may damage significantly the human health when they exceed certain levels in the body. For example specific precautions should be taken for the diet of pregnant women and the...

Groundwater in the area of eastern Croatia contains increased concentrations of organic compounds, primarily natural organic matter (NOM). Organic compounds in water become a problem in drinking water treatment, especially during water disinfection with chlorine, when harmful disinfection by...

The potential of rainbow fungus (Coriolus versicolor) for bioremediation of bagasse soda pulp bleaching effluent containing chlorinated organic compounds was investigated without co-substrate addition. Initially, the effect of each of the operating variable including time, temperature, pH, and...

The present paper aims at a treatment technique designed for special industrial wastewaters contaminated with only traces of halogenated organic compounds (HOCs) – concentrations which are nevertheless large enough to make a discharge into municipal sewage works impossible. Our research follows the...

Solar saltworks are most efficient converters of solar energy into an inorganic commodity. Conversion rate of solar radiation into removal of water vapour from the brine takes place with 45% efficiency. Solar salt requires only a fraction of man made energy compared with salt produced by solution...

Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. The aim of this study was to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light process and Fenton’s reactions in wastewater...

Heterogeneous photocatalysis is an advanced oxidation process (AOP) which has been widely studied by numerous researchers in the world and is used to degrade or remove a wide range of pollutants in water and air. The photocatalytic oxidation and mineralization of phenol in aqueous catalyst...

The final effluents from pulp and paper industry, even after biological treatment, often contain a plethora of unwanted by-products, which confer them colour and toxic characteristics. The aim of this work was to promote degradation of organic matter and remove colour by contacting fungi Pleurotus...

Phytoremediation is a low cost alternative solution to soil contamination compared with traditional removal and/or disposal techniques. One of the phytoremediation technologies is the phytovolatilization, whereby the contaminant is not primarily accumulated in above-ground tissues, but is instead...

Photocatalysis is a promising method for eliminating the volatile organic compounds emitted from various industrial processes because mild or ambient conditions are used. Titanium dioxide is commonly used as photocatalyst and ultraviolet light is utilized for decomposing gas phase pollutants. In the...

A chemical vapour sensor working with a monochromatic light source and based on optical fibre coated with a thin siloxane polymer film has been developed for in situ monitoring of volatile organic compounds, such as ethylbenzene, xylene (o-xylene), heptane, octane, chloroform, carbon tetrachloride...

Industrial facilities emit pollutant air that contains volatile organic compounds (VOCs) and reduced sulphur compounds (RSCs) which are nuisance, corrosive to materials and dangerous to health. In recent years, biofiltration has replaced numerous conventional processes (i.e. adsorption) due to its...

Pollutants posing health risks to human health and to the aquatic environment often occur in drinking and surface waters, as a result of disinfection practices, agricultural and industrial activities, wastewater discharges. Toxic pollutants belong to different chemical categories, including...
