The Town

Rodgau has nearly 50.000 citizens and have their own sewage treatment plant. The wastewater of the whole town has to be treated to the point where it can be released in the back which gives the town its name, the Rodgau. There are two main sources of wastewater, municipal and industrial waste water. (www.rodgau.de 8.9.17) The objective of Sewage Treatment in Rodgau especially is that the waste water after beingprocess can go directly to Rodau river. The drinking water of Rodgau is not coming from thesewage treatment plant. (Bundesministerium der Justiz und für Verbraucherschutz) The sewage Treatment Plant in Rodgau has the capacity up to 75.000 citizen value (EW). In this sewage treatment there are physical, chemical and biological processes. In the chemical processes there are neutralization, oxidation and reduction processes. The physical treatment including sedimentation, extraction, and adsorption process. Then main steps of the sewage treatment are screening and filtration of the bigger pollutants, transforming of elements and separating the sludge.( ATV-Handbuch (1999)) Different options can be seen which were used in the Rodgau plant. The Rodgau sewagetreatment plant is at state of the art, very efficient and can be a great example for sewagetreatment plants of other cities.

In this work graphene was used for evaluation of its adsorption behavior and performance in removing phthalate esters and pharmaceuticals in municipal wastewater. Di-n-butyl phthalate (DnBP), di-(2-ethylhexyl) phthalate (DEHP), acetaminophen (ACE), caffeine (CAF), cephalexin (CLX), and sulfamethoxazole (SMX) were emerging contaminants (ECs) with detection frequencies over 92% in a one-year monitoring of the occurrence of ECs in influent samples of a sewage treatment plant in Taiwan. Thus, these ECs were selected as the target contaminants for removal by graphene adsorption process. Experimental results showed that the adsorption isotherm data were fitted well to Langmuir model equation. It was also found that the adsorption process obeyed the pseudo-second-order kinetics. A graphene dosage of 0.1 g/L and adsorption time of 12 h were found to be the optimal operating conditions for the ECs of concern in model solutions in a preliminary study. By using the determined optimal operating conditions for removal of such ECs in actual municipal wastewater, removal efficiencies for various ECs were obtained and given as follows: (1) DnBP, 89%, (2) DEHP, 86%, (3) ACE, 43%, (4) CAF, 84%, (5) CLX, 81%, and (6) SMX, 34%.

Sludges are byproducts of sewage treatment process. Land application of sewage sludge is one of the final steps of waste water treatment, but solubilization of toxic metals restricts this method of sludge disposal. In our paper cobalt, zinc, cadmium and cesium sorption by suspension of non-treated activated sewage sludge (14 g/dm3, dry wt.) from waste water spiked with 60CoCl2, 65ZnCl2, 109CdCl2 or 137CsCl were determined in laboratory experiments at 20°C. Activated sludge supplied by the municipal sewage treatment plant in Zeleneč (Trnava region, Slovakia) showed high efficiency to sorb Co2+, Zn2+, Cd2+ and Cs+ ions from waste water pH 6-7. The process can be characterized by the concentration equilibrium (Csolid/Cliquid) typical for sorption processes. Efficiency of the sorption increased in the order Cs < Co < Zn < Cd. Metal sorption process was not inhibited by pretreatment of the sludge with 0.2% formaldehyde or thermal inactivation at 60°C, what confirms that the process was not dependent on metabolic activity of the sludge. Cobalt, zinc, cadmium and cesium were easily removable from the sludge by washing with diluted HCl, EDTA or water solutions of the corresponding metal ions, but with low efficiency by deionized water.

This paper presents the results of a preliminary analysis of Palic-Ludas catchment area near the town of Subotica in Serbia. With the aim of improving environmental situation of the considered catchment, the authors started by conducting a detailed investigation of the current situation of this area. The examination focused on obtaining and evaluating existing data in order to derive some conclusion about the present status of this catchment. This paper offers a description of the important water bodies on Palic-Luda catchment, while including the most influential hydraulic structures. After evaluating the gathered data, a basic water budget model ofPalic-Ludas lake system was constructed. The model included all the main water budget elements, the outflow from the sewage treatment plant into Lake Palic, precipitation, evaporation as well as the ground water interflow. After conducting a one year simulation the results were assessed and the influence of each component of the water budget was examined.

Abstract The treatment of wastewater is an essential factor in preventing pollutants and promoting the quality of the water. The inherent complexity, influential impact and the solid waste infrastructure lead to confusion and variance in the primary clarifier for wastewater. These inconsistencies lead to variations in the purity and capacity constraints of wastewater and the existential impact of water receipt. The water treatment is a complicated task that has means of chemical, technical & biochemical influences. A credible ANN method is necessary for another waste water treatment plant to prevent the breakdown of the processes. Virtual reality seems to have become a strong solution for preventing waste management uncertainties and problems. This is not only due to high deformations but also to significant external disturbances that water systems are controlling challenges. Climate is among the most significant of such disturbances. Various environmental conditions actually include different influx frequencies and levels of substances. Water contamination has become one of the extremely serious growing conservation; sewage treatment plant identification is a key major issue here and the agencies enforce tighter requirements for the operating of wastewater software systems. This article plans to create models of achievement and prospects for the possible future guidance of recent research borders for the use of artificial intelligence in wastewater treatment plants which concurrently deal with pollutants. This study has shown us that the composite ANN provides a greater level of competence in plant prediction and systemization.
