Treatment performances of two wastewater treatment plants (WWTPs), located in North-Eastern Algeria (Souk-Ahras and Sedrata) were tested using ASM1 model. The model, to be considered as a decision tool for the appropriate management of activated sludge systems, served for the prediction of both WWTP behaviours under different operating conditions. In Sedrata WWTP the first management scenarios is based on an increase of inflow rate, taking into account a new transfer volume from a nearby zone. In a second scenerio, the ultimate flow of 40 000 m³∙d^–1 is estimated. Regarding Souk-Ahras WWTP, three scenarios were tested. The first tested the impact of an increase of the extraction flow rate and yielded a reduction by 37% of sludge production. The second dealt with the management of the mass budget of substrata and biomass. Finally, the third application was devoted to the estimation of the plant ultimate capacity, estimated to be 60 000 m³∙d^–1.

Stosując model ASM1, testowano działanie dwóch oczyszczalni ścieków zlokalizowanych w północnowschodniej Algierii w miejscowościach Souk-Ahras i Sedrata. Model, traktowany jako narzędzie w podejmowaniu decyzji co do właściwego zarządzania systemem osadu czynnego, służył przewidywaniu zachowania się obu oczyszczalni w różnych warunkach operacyjnych. W oczyszczalni Sedrata w pierwszym scenariuszu zarządzania założono zwiększoną prędkość przepływu uwzględniającą dodatkową objętość ścieków dostarczaną z pobliskiej strefy. W drugim oszacowano końcową przepustowość równą 40 000 m³∙d^–1. W odniesieniu do oczyszczalni w Souk-Ahras testowano trzy scenariusze. W pierwszym rozpatrywano wpływ zwiększonej prędkości przepływu, w efekcie uzyskano 37-procentowe zmniejszenie produkcji osadu. Drugi scenariusz dotyczył zarządzania bilansem masy podłoża i biomasy. Trzeci z kolej polegał na ocenie docelowej przepustowości ścieków szacowanej na 60 000 m³∙d^–1.
