Constructed Wetlands for Combined Sewer Overflow Treatment
Combined sewer systems are designed to transport stormwater surface runoff in addition to the dry weather flows up to defined limits. In most European countries, hydraulic loads greater than the design flow of wastewater treatment plants are discharged directly into the receiving water bodies with minimal treatment (screening, sedimentation) or with no treatment at all. One feasible solution to...
متن کاملModelling of biofilters for ammonium reduction in combined sewer overflow.
Biofiltration has proved to be a useful system to treat combined sewer overflow (CSO). The study presented uses numerical simulation to detect the critical operating conditions of the filter. The multi-component reactive transport module CW2D was used for the simulation study. Single-event simulations of lab-scale-column experiments with varying boundary conditions regarding the throttle outflo...
متن کاملModelling of organic matter degradation in constructed wetlands for treatment of combined sewer overflow.
Subsurface vertical flow constructed wetlands (CWs) have been found to be a useful system to treat combined sewer overflow (CSO). The study presented uses numerical simulation to increase the understanding of the fundamental processes of COD degradation in CWs for CSO treatment. The multi-component reactive transport module CW2D was used for the simulation study. The simulation results showed t...
متن کاملConstructed Wetlands for Combined Sewer Overflow Treatment—Comparison of German, French and Italian Approaches
Combined sewer systems are designed to transport stormwater surface run off in addition to the dry weather flows up to defined limits. In most European countries, hydraulic loads greater than the design flow are discharged directly into receiving water bodies, with minimal treatment (screening, sedimentation), or with no treatment at all. One feasible solution to prevent receiving waters from s...
متن کاملImpact of Combined Sewer Overflow on Wastewater Treatment and Microbiological Quality of Rivers for Recreation
Within the framework of a one-year study the treatment capacity of a municipal wastewater treatment plant (WWTP) was evaluated, with regard to fecal indicator bacteria (FIB) and to their influence on the recipient. The logarithmic reduction rates for fecal coliforms (FC), Escherichia coli (EC) and intestinal enterococci (IE) were 2.84, 2.90 and 2.93. In the investigated period of time, the test...
