Operational analysis rotating biological contactor -activated sludge or nitrifiying trickling filte-activated sludge?

Municipal and industrial wastewater possess potentially hazardous implications for the environment. Consequently, appropriate treatment measures must be implemented before its discharge into water bodies, onto land, or reuse. The provision of clean water constitutes a significant global priority. This investigation seeks to contribute to developing an efficient Wastewater Treatment Plant (WWTP). The implementation of technical simulation and modeling is of paramount importance in the design, construction, and prediction of the requisites for WWTP designs. Simulating a project before its implementation can mitigate additional expenses, and the project can be thoroughly assessed and scrutinized from various angles. This examination proposes utilizing a combined nitrifying trickling filter/activated sludge (NTF/AS) process to modernize a Municipal Wastewater Treatment Plant (MWWTP). The performance of MWWTPs was analyzed and compared based on the combined rotating biological contactor (RBC)/AS process and the combined NTF/AS process. Two wastewater treatment plants were implanted and technically evaluated using data from the Ekbatan treatment plant in Tehran. In these scenarios, the GPS-X software was employed to explore the impact of variations in raw wastewater between their minimum and maximum intervals on the quality of effluent. Due to the divergence in the inlet effluent range, more precise outcomes were attained. In the fixed flow scenario, the RBC/AS wastewater treatment plant achieves removal percentages of ۹۰.۵۱, ۸۹.۷, ۹۵.۱۴, ۱۴.۸, and ۷۶.۴۱ for COD, TSS, BOD۵, total phosphorus, and ammonia in the effluent, respectively.the RBC/AS method yields removal percentages of ۹۲.۲, ۹۰.۸۳, ۹۷.۲۲, ۱۷.۸, and ۷۳.۷۶ for the same parameters in the wastewater treatment plant. It is worth noting that both methods comply with Iranian standards, ensuring the quality of the effluent is suitable for discharge into the environment. One advantage of implementing the NTF method is the reduction in sludge yield.
