Design and Simulation of a Wastewater Treatment Plant Using Software in the Locality of Namora, Cajamarca, 2025

Abstract

Wastewater treatment is a priority in rural areas like Namora, Cajamarca, due to the limited sanitation infrastructure. Therefore, this research designed and simulated a wastewater treatment plant (WWTP) using STOAT software, including pretreatment, sedimentation, a UASB reactor, and tertiary filtration, under a quantitative, non-experimental, and correlational approach. The results showed efficiencies of 95% for BOD5, 90% for suspended solids and nitrogen, and 85% for phosphorus, while a hydraulic retention time of eight hours optimized reactor stability and effluent quality. Thus, computational modeling was consolidated as an effective tool for proposing sustainable solutions for rural sanitation.
