Article Synopsis
- The study aims to create a model for predicting the long-term performance of High-Rate Activated Sludge (HRAS) processes, focusing on removing carbon, nitrogen, and phosphorus.
- The model builds on existing Activated Sludge Models (ASM1 and ASM3) and includes important mechanisms like adsorption and substrate storage, following a detailed calibration process with data from a pilot HRAS plant.
- The model achieved over 70% prediction efficiency for several key metrics, but identified uncertainties, especially in soluble COD estimates, attributed to variations in wastewater characteristics not fully accounted for in the model.

Article Synopsis
- Coagulants from water treatment plants typically produce sludge that is often sent to landfills, but utilizing this sludge is encouraged for sustainability.
- This study explores using WTP sludge, specifically iron sludge, as a substitute for conventional coagulants in a high-rate activated sludge system, finding it enhances treatment efficiency.
- The addition of iron sludge improved particulate chemical oxygen demand removal and sludge settleability, while also reducing overall operational costs by 11%, indicating potential benefits for both water treatment facilities and environmental sustainability.
