Summary

The study simulated two wastewater treatment technologies, finding the moving bed biofilm reactor (MBBR) superior for nitrogen removal compared to the activated sludge process (ASP). MBBR was selected for upgrading the plant.

Background:

Existing wastewater treatment plants require upgrades to enhance nitrogen removal efficiency.
Simulation modeling is a valuable tool for evaluating and selecting appropriate treatment technologies.

Purpose of the Study:

To compare the performance of a conventional activated sludge process (ASP) and a moving bed biofilm reactor (MBBR) for nitrogen removal in wastewater treatment.
To support the decision-making process for upgrading an existing wastewater treatment plant.

Main Methods:

Development of mathematical models for both ASP and MBBR processes.
Calibration of models using data from parallel pilot plants operating at the existing facility.
Steady-state analysis to evaluate carbon and nitrogen removal efficiencies.

Main Results:

Both ASP and MBBR showed similar carbon removal efficiencies.
MBBR demonstrated superior nitrogen removal performance, particularly at low temperatures.
Simulations did not confirm anticipated space savings for the MBBR process.

Conclusions:

The moving bed biofilm reactor (MBBR) was selected as the preferred technology for upgrading the wastewater treatment plant due to its enhanced nitrogen removal capabilities.
The developed process model will be instrumental in optimizing the final plant configuration and operational parameters.
