Evaluation and Optimization of COD Removal Performance for a Domestic Wastewater Treatment Plant by Response Surface Methodology: The Case of Van Muradiye

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the performance of the Van Muradiye Domestic Wastewater Treatment Plant was evaluated with Response Surface Methodology (RSM). The effects of pH, conductivity, dissolved oxygen (DO), and suspended solids (SS) on the chemical oxygen demand (COD) removal efficiency were evaluated using samples collected from the plant's inlet and ...

Experimental investigation of simultaneous nitrification-denitrification and phosphorus removal in pilot-scale sequencing batch moving bed biofilm reactors (SB-MBBRs)

Water Resources and Industry
Sequencing batch moving bed biofilm reactors have been widely used in commercial wastewater treatment facilities for organic carbon and nitrogen removal. However, these reactors can remove low phosphorus (P) levels. Therefore, this study investigated the

Post denitrification in a moving bed biofilm reactor process

Water Science and Technology, 1998
The Sjölunda wastewater treatment plant in Malmö Sweden will have to comply with future effluent standards of less than 10 mg BOD7/l, 8 mg N/l and 0.3 mg P/l. The upgrading for enhanced nutrient removal will be based on a site-specific concept where a tertiary treatment step for post-denitrification will be required.

Evaluating Oxygen Demand in Mainstream Anammox, A2O and Partial Denitrification/Anammox (PD/A) Processes: A Gradient‐Based Sensitivity Analysis

Water and Environment Journal, EarlyView.
This graphical abstract illustrates the oxygen demand reduction potential of the mainstream anammox process compared to conventional A2O and PD/A processes. It visually demonstrates maximum oxygen savings of 28.25% and 18.58%, respectively, under optimal conditions.
