Abstract/Contents

Abstract: Onsite, decentralized, and satellite wastewater treatment facilities are ideal to meet the increasing water demand and wastewater production in the US. As urban centers grow, smaller facilities ease the stress on wastewater collection systems by reducing flow, and enable wastewater reuse at the point of generation, which reduces potable water consumption. However, working on a smaller scale poses challenges — changes in influent quality can cause biological system disturbances that are difficult to recover from, and can put facilities out of compliance. Early fault detection is key to preventing downtime, avoiding effluent limit exceedances, and reducing the cost of operation. A program designed to identify system faults is developed using multivariate statistical analysis, and challenged by common faults in activated sludge wastewater treatment systems. Additionally, the early-detection program is designed to optimize system operation to meet a desired effluent quality, allowing for greater control when producing water for potable or non-potable reuse.
