“…Performance evaluation of existing treatment plants is required (1) to assess the existing effluent quality and/or to meet higher treatment requirements and, (2) to know about the treatment plants whether it is possible to handle higher hydraulic and organic loadings. Performance appraisal practice of existing treatment plants is effective in generation of additional data which also can be used in the improvement in the design procedures to be followed for design of these plants.…”

The present study has been undertaken to evaluate performance efficiency of wastewater treatment plants in El-Gharbia governorate in Egypt. The wastewater treatment plants using different biological treatment techniques (conventional activated sludge, oxidation ditch, extended aeration, rotating biological contactors and aerated lagoons processes). Wastewater samples were collected from both influent and effluent of each plant and the wastewater quality were determined at central laboratory of Garbyia Water Co. The performance of each plant was estimated based on the treated wastewater quality data. Correlations between influent and effluent TSS, COD and BOD5 were developed. Kotour WWTP operates with the oxidation ditch technology exhibits the highest performance efficiency, while Tanta WWTP operates with conventional activated sludge technology exhibits the lowest one. The results show that, all collected samples from Tanta, and El Mehala El Kobra WWTPs were exceeding the Egyptian Permissible limits (COD: 80 mg/l) while the samples collected from Mehalet Marhom, Mehalet Menof, Kotour, El Santa, Shernak and Zefta were complying the Egyptian regulations.

STRESZCZENIEW artykule przedstawiono sposób wykonania kalibracji biokinetycznego modelu osadu czynnego przy użyciu programu komputerowego BioWin. Schemat komputerowy został opracowany na podstawie oczyszczalni ścieków pracującej w technologii sekwencyjno -przepływowej. Do kalibracji biokinetycznego modelu osadu czynnego wykorzystano wyniki badań ścieków dopływających i oczyszczonych pochodzących z istniejącego obiektu. Wynikiem przeprowadzonych analiz były zmiany w biokinetycznym modelu w zakresie parametrów kinetycznych oraz pracy urządzeń oczyszczalni. Przedstawiony sposób badania wpływu wybranych parametrów biokinetycznego modelu osadu czynnego (m.in. maksymalna szybkość wzrostu autotrofów, udział zawiesiny organicznej w zawiesinie ogólnej, skuteczność pracy osadników wtórnych) może być wykorzystany podczas prowadzenia badań symulacyjnych innych oczyszczalni ścieków.Słowa kluczowe: biokinetyczny model osadu czynnego, kalibracja, parametry kinetyczne modelu. DETERMINATION OF ACTIVATED SLUDGE MODEL ASDM PARAMETERS FOR WASTE WATER TREATMENT PLANT OPERATING IN THE SEQUENTIAL-FLOW TECHNOLOGYABSTRACT This paper presents a method for calibration of activated sludge model with the use of computer program BioWin. Computer scheme has been developed on the basis of waste water treatment plant operating in the sequentialflow technology. For calibration of the activated sludge model data of influent and treated effluent from the existing object were used. As a result of conducted analysis was a change in biokinetic model and kinetic parameters parameters of wastewater treatment facilities. The presented method of study of the selected parameters impact on the activated sludge biokinetic model (including autotrophs maximum growth rate, the share of organic slurry in suspension general operational, efficiency secondary settling tanks) can be used for conducting simulation studies of other treatment plants.

“…Detailed description is presented in Mikosz (1999). The model usually needs to be checked and recalibrated each time it is used for the optimization of the existing plant, but for many simulation studies, a lower quality of calibration and validation is sufficient (Langergraber et al 2004). As the model proved to be effective in the past, this time it was only recalibrated statically.…”

Industrial wastewater discharged to a municipal sewage system may often be a source of valuable organic substrate for biological processes at a municipal wastewater treatment plant (WWTP). In such situations, the pretreatment of wastewater at an industrial plant should be minimized, in order to maintain the favourable structure of organic material in influent to a WWTP. A frequent problem is how to determine the maximum industrial pollution load that can be discharged, without compromising the treatment capability of a WWTP. This article presents a method based on computer simulation that can be used for this purpose. As a result, the method produced the permissible industrial pollution load that could be discharged safely, and the relationship between chemical oxygen demand (COD) load and required biomass concentration as a function of process temperature. The method was tested at a fruit-processing plant and municipal WWTP, located in Poland. The results of this study have shown that the bioreactor should be operated at a biomass concentration varying between 3,600 and 5,400 g m -3 in function of the process temperature. Under such operational conditions, the WWTP would be able to accept the permissible industrial COD load of above 9,000 kg COD d -1 for a wide range of temperatures, namely 14-19°C. If the WWTP was operated at a constant biomass concentration, its permissible industrial COD load would be reduced to 7,500-9,000 kg COD d -1 . The method can be applied to other municipal WWTPs with activated sludge that receive industrial effluents.
