Gaussian process regression for monitoring and fault detection of wastewater treatment processes
Monitoring and fault detection methods are increasingly important to achieve a robust and resource efficient operation of wastewater treatment plants (WWTPs). The purpose of this paper was to evaluate a promising machine learning method, Gaussian process regression (GPR), for WWTP monitoring applications. We evaluated GPR at two WWTP monitoring problems: estimate missing data in a flow rate ...

Odorous compounds monitoring, olfactometry, human noses? Which option should you choose?
Odors are very distinct air contaminants as they generate nuisances and can affect nearby residents. The factors playing a role in the determination of odor annoyance are: odor concentration and intensity, frequency, appreciation, duration and location. Several solutions are available as sensory approach (dynamic olfactometry), sensor technologies (portable sensors, electronic noses, etc.). In ...

Digital transformation, key to improving operations in WWTPs
Integrating all data sources into a single environment is a fundamental step in the digital transformation of wastewater treatment plants to provide them with comprehensive control of all their processes, according to Idrica’s report “Digital transformation of WWTPs: key to a more sustainable future”. The most advanced digital transformation uses data to create, train and feed ...

Open Channel Flow Monitors retired after 16 years continuous service - Case Study
Long Sault WWTP Influent Flow Monitors Greyline Open Channel Flow Monitors were installed at the Wastewater Treatment Plant in Long Sault, Ontario when the SBR plant was originally commissioned in 1995. But after 16 years of continuous service, components for the old models became obsolete. Plant operators Caneau Water and Sewage Inc. decided to replace the instruments and new Greyline OCF 5.0 ...

Location of Low-cost Sensor-based Air Quality Monitoring Devices
Monitoring the pollutant concentration is fundamentally important to develop and evaluate pollution control strategies. It enables us to understand the trend and extent of pollution by identifying pollution sources, and thereby indicating where more efforts are needed. It is important to ensure that the measured air quality provides adequate and accurate information. One of the key factors ...

H2S monitoring at Stanford WWTP - Case Study
Overview Odour pollution in the form of Hydrogen Sulfide was a major problem at the Stanford Waste Water Treatment Plant. The city administrators did not have data to identify and correlate with the complaints raised by nearby citizens. Oizom’s odour monitoring solution was deployed with real-time data visualization at the WWTP. Oizom’s partner Metersys were empowered to understand ...

Chemical fingerprinting of saline water intrusion into sewage lines
High salinity in sewage sludge can affect not only the operation of wastewater treatment plants (WWTPs) but also the quality of treated water generated, thereby limiting its downstream reuse. Using data on geochemical parameters, both for the central WWTP in Abu Dhabi, UAE, and literature values for potential regional saline water sources (e.g., shallow groundwater and regional Arabian Gulf ...

Online Cu, Zn, As, Se, Cd and Sb Monitoring at an Industrial Smelting Wastewater Treatment Plant
This application focuses on measuring inorganic metals including: copper (Cu), zinc (Zn), arsenic (As), selenium (Se), cadmium (Cd), and antimony (Sb), using Cooper Environmental’s Xact® 920, a continuous multi-metal monitor based-on energy dispersive X-ray fluorescence. Industrial facilities consume and discharge various chemicals as a byproduct of the commodity they produce. The ...

Discharge quality from municipal wastewater treatment plants and the Sludge Biotic Index for activated sludge: integrative assessment
Wastewater treatment plants (WWTPs) are scrutinized by Environmental Authorities particularly regarding the compliance to discharge limit values fixed by national and local regulations. An integrated approach is necessary to achieve the objectives established with Directive 2000/60/EC (WFD) considering the ecological status of the receiving water body and the quality of the discharge. ...
