Adsorption of Cu (II) ions by untreated sugarcane bagasse (USCB) and treated sugarcane bagasse (TSCB) was investigated. Sugarcane bagasse was treated with 0.1M oxalic acid prior to TSCB adsorption studies. Dependence of Cu (II) adsorption on pH, contact time, temperature and initial concentration of...

Granular activated carbon (GAC) was used in an Anammox process treating synthetic wastewater with the aim of evaluating its use as a growth nucleus to enhance granule formation. In an expanded granular-sludge-bed reactor, granules were formed demonstrating excellent retention characteristics with an...

The idea of wastewater application on soils, returned to Western Hemisphere during 1950-60. Modern living requires an increased per capita use of water for coverage of individual needs. Nowadays, two main principles related to water management seem to gain the attention of both the scientific...

Raw municipal landfill leachate is extremely polluted wastewater and it regards as one of the drawbacks of the sanitary landfill treatment method. If the untreated landfill leachate is discharged to the natural environment, a great problem for the environment can be created, particularly for the...

The best method to treat seawater is known to be the use of reverse osmosis (RO) systems. The cost factor becomes the most important issue when using RO systems. Although quite costly, RO systems are essential systems for ships. As known very well, water is a critical resource on ships, especially...

The aim of this paper is to highlight the way towards the exploitation of treated wastewater for food crops production in order to cope with the acute water scarcity and its hazardous consequences. Reclaimed water reuse has not been practiced in Tobruk, and hence, lack of relevant data and...

Two greenhouse pot experiments were conducted in Agrinion, Greece. The impact of treated municipal wastewater (TMWW) and sludge (i) on the growth of Lactuca sativa L. var Longifolia (lettuce) and (ii) on the extent of soil pollution with heavy metals was studied. Soil pollution was assessed by...

This paper evaluates the effect of wastewater reuse on the germination and growth at early stages of barley and onions. Treated wastewater, partially treated industrial wastewater, grey water, and car wash water, in addition to tap water as control were used to test their effect on germination...

Wadi Auranah is one of the potential wadis in respect of land use, located on the western shield (Hijaz escarpment) of Saudi Arabia. A spatio-temporal change assessment of this wadi (valley) was conducted with the help of landsat data. The results of the spectral analysis and NDVI for vegetation...

Recently, the fate of emerging compounds in environmentally relevant samples has attracted considerable attention. Solar semiconductor photocatalysis may offer an appealing methodology to treat such contaminants. At the same time the use of solar photocatalysis for water and wastewater disinfection...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction of textile industry wastewater by electro-Fenton (EF) oxidation, was studied at batch experimental conditions. 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 present paper discusses an integrated electrochemical decolorization/degradation treatment procedure of indigo carmine dye, which comprises electrocoagulation, electrooxidation and advanced electrochemical oxidation using the electro-Fenton process. The electrocoagulation process is performed by...

Natural systems offer an economic solution for the treatment of wastewater from small settlements. This study presents a detailed technical analysis of three stabilization pond systems designed to treat municipal wastewater, varying in capacity from 250 to 1400 population equivalent. Construction...

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...

The performance of a laboratory scale electrocoagulation system for the removal of Cr and Ni from model wastewater was studied systematically using iron and aluminum electrodes with an effective surface area of 13.8 cm2 and a distance of 4 cm. The influence of several parameters, such as initial...

Many studies have been conducted to increase the efficiency of hydrogen peroxide (HP) in wastewater disinfection to make HP disinfection more cost-effective with respect to reduced concentration and detention time. In this study, the effects of HP, copper ions (Cu2+), and 1 atm. pressure-dissolved...

Wastewaters from fossil fuel refining, pharmaceuticals, and pesticides are the main sources of phenolic compounds. Those with more complex structures are often more toxic than the simple phenol, and yet little is known about the treatment of wastewater containing a mixture of phenolic pollutants....

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...

Olive oil wastewaters (OOMW) are dark effluents which pose serious environmental problems. The aim of this work was to apply biological treatment with Pleurotus spp., and chemical treatment, through oxidation by Photo-Fenton, to OOMW. The biological treatment was not very efficient in colour...

A two-year monitoring program was undertaken in a vertical flow constructed wetland treating wastewater from Gomati, a village in Chalkidiki, North Greece. This constructed wetland operates since 2003. The monitoring campaigns were organized every 15 days. Water quality samples were collected at the...

The scope of this paper is the evaluation of wastewater reuse quality criteria and treatment specifications, appropriate to Greek conditions. The parameters that affect wastewater reuse criteria were taken into consideration, concerning among others reuse priorities, available treatment plants and...

The US Environmental Protection Agency (USEPA) recently introduced more stringent arsenic regulations by lowering the maximum contaminant level (MCL) to 10 ìg l-1 (ppb) arsenic in drinking water. During the present study, an iron solution injection sand filtration process was designed and tested to...

Water resulting from the dewatering process of petroleum storage tanks was treated in a pilot separator to investigate the effectiveness of the combined action of a coagulant (aluminum sulfate) and a cationic flocculant (NALCO 71403). Central composite design of experiments was used to construct...

Samples were taken from Metamorphosis/Attica combined treatment plant for municipal wastewater and septage, which treats about 12000 m3 d-1 of municipal wastewater and 8000 m3 d-1 of septage, and analyzed for solids, COD, ammonia, nitrate, orthophosphate, polyphosphate and total phosphorus. Ammonia...
