The Fenton process, one of advanced oxidation processes (AOPs), has been widely implemented to remove COD and color for dye wastewater as a pre-treatment or posttreatment process. In recent years, Fenton-like processes have received considerable attention in wastewater removal. The main purpose of the present study was to determine the optimal operational conditions of the Fenton- like process by using raw limonite ore at various concentrations of hydrogen peroxide and raw limonite ore for treatment of dye wastewa...

Vlasina lake in Southeast Serbia is classified as an Area of Distinct Land Use. Due to high environmental protection standards, the Master Plan of the area forsees the need for high levels of protection from waste water, storm water, and sediment. The storm waste water and sediment management system implies infrastructure that consists of open channels and gutters, leading to detention basins. Prior to release into the lake, storm water and sediment from the immediate lake bank area are treated and managed within ...

In this work are presented the results of determination of physical, chemical and bacteriological parameters of water in five levels (7,40; 11,40; 18,40; 28,40 and 30,40 m) of the artificial “Radoniqi” lake, in order to select the most convenient level that offers necessary treatments to be prepared for drinking water. The obtained results show that the water of the “Radoniqi” lake is of a very high quality, soft and the water of the third level is the most suitable to be prepared for drinking after necess...

Surface and ground waters are used for potable water supply. Some of they contain iron and manganese. The presence of these impurities in natural waters is undesirable due to their tendency to oxidize and precipitate under a variety of conditions, causing both aesthetic and treatment water problems. The possibility to use zeolite for iron (Fe) and manganese (Mn) removal in low concentrations from water is examined in this paper. Ion-exchange process to the maximum allowable limits of 0.3 mg/L for iron and 0.05 mg/...

Performing a numerical analysis of water well drilling sector of Turkey was aimed in this study. Within this purpose, number of the machinery in equipment pool of the institutions and companies which are involved in the water well drilling, yearly drilling quantities, drilling equipment preferences and geological data of 2640 water well drilling boreholes opened in 73 provinces between the years of 1998 – 2006 and the results below have been reached: The Municipalities in Turkey meet 95 \% of their drinking wate...

Rocks deep below the surface store heat and for every 100 m in depth the temperature increases by approximately 3oC. When the mines were closed, the mine galleries flooded. The heat of the rocks warms water, which is used as input to heat pumps for heating and cooling of buildings. The Remining-Lowex Project aims to demonstrate the use of water in abandoned coalmines as a source of renewable energy and to prove its economic viability. This new approach for utilization of sustainable energy from worked out coalmine...

The results of investigations in physical – chemical, bacteriological and thermodynamic characteristics of drinking water of wells, taken from some village in some primary school of Vushtrri Municipality are presented. Taking into consideration all important parameters we found they were within given limits , just temperature that is higher than given limits, so analysis of water samples for thermo tolerant faecal coli forms which are carried out by passing a measured quantity of water through sterile filter tol...

A finite difference method for solving the initial boundary value problem for one dimensional nonlinear system equations for investigating the quality of water on the model of shallow water flow over on isolated ringe in a class of discontinuous functions is suggested. In order to develop the numerical algorithm the special auxiliary problem having some advantages over the main problem is introduced. The solution obtained from the auxiliary problem represents all physical nature of the investigated problem with a ...

Low concentration of chlorinates maybe found in wastewater, contaminated soils and air due to different industrial sources. Low level of Volatile Organic Compounds (VOC)’s could be removed by adsorption, incineration and biofiltration methods. These methods have some disadvantages such as removal efficiency or high operation cost. Chlorine has been removed from the chlorinated aliphatic compounds under anaerobic conditions. The aim of this study was to investigate biological treatment of DCM and CT in high flow ...

Almost any places in the world, people are using groundwater for drinking and usage needs because of reduced surface and spring waters sources in last decate. Settlement areas, agricultural areas, solid waste areas, industrial areas, waste water discharge areas have always potential to pollute the aquifer media. Boreholes areas for abstracting the ground water has to be picked up not to be carrying risk getting pollution on surface. So it’s necessary for the engineers that hydrogeologic properties has to be choo...

Methods of estimating yield from ungaged watershed may be by using of climatic factors, only geographic location and watershed and climatic factors. Methods for estimating yields, as regional analysis, water accounting, direct runoff method, climatic and geographic factors, should be considered as giving estimates so broad that the influence of specific factors have large margins or error. Hydrologic simulation models in watershed modelling use mathematical equations to calculate results like runoff volume or peak...
