Operation and Upgrading the Capacity of Wastewater Treatment Plants by Activated Sludge Method Using the Mass Flux Approach (Case Study of Wastewater Treatment Plant of Shahrak Gharb in Tehran

One of the major challenges in the operation of wastewater treatment plants is the lack of experts and the lack of use of new methods in the management of this system, which has rarely been addressed in the past. Therefore, the application of new methods in exploitation is of great importance and in...
