In this study, it is aimed to investigate the effects of different bed materials and feeding patterns of wastewater on the treatment performance of wetland roof systems using two different plants.. In this study, WRs with selected plants, namely Kyllinga Nemoralis (KN) and Wedelia Trilobata (WT) were investigated for evaluating wastewater treatment performance, biomass growth and the investigation of removal rate constants of experimental WRs system.

The effect of electrical current frequency on the physicochemical properties of wastewater, wich allows to identify the optimal treatment regimes that promote the. intensification of various processes taking place in an aqueous medium or in the presence of water. Next researches will be done on wastewater treatment systems, in order to evaluate optimizing impacts of physicochemical properties of water because of alternating current frequency..

Figure (2.1): A centralised wastewater treatment system (Anaant, 2003). Figure (2.2) illustrates the concept of decentralised wastewater treatment plant . Figure (2.2): Decentralised wastewater treatment system (DEWATS) (Anaant, 2003). The essential functions of the septic tank are as follow. Septic tanks (Figure 2.3a and 2.3b) provide a relatively quiescent body of water 11 where the wastewater is retained long enough to let the solids, oils and greases separate by both settling and flotation.

The adsorption time was an important parameter for wastewater treatment. The effect of adsorption time on Cr(VI) adsorption was shown in Figure 3. The role of the adsorption time was examined at different times between 5 and 240 min. The results show that the maximum adsorption for both samples occurred within the first 60 min.

Abstract: In wastewater treatment, scientific and practical models utilizing numerical computational techniques such as artificial neural networks (ANNs) can significantly help to improve the process as a whole through adsorption systems.. In the modeling of the adsorption efficiency for heavy metals from wastewater, some kinetic models have been used such as pseudo first-order and second-order.

The treatment of leachate requires a complicated wastewater treatment system including chemical, physico-chemical, biological, and advanced treatment processes. The high ammonia concentration of leachate usually causes inhibition for microorganism in biological treatment. Therefore, it is necessary to remove ammonia from the leachate to lower concentrations to make it suitable for further treatment processes.
