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 ...

Real-time process dynamics monitoring in Anammox reactors

Process dynamics in Anammox systems were evaluated through continuous monitoring of pH, oxidation reduction potential (ORP) and conductivity in two separate newly started-up sequencing batch reactors, one seeded with an enriched Anammox sludge and the other seeded with mixed activated sludge. The pH and ORP profiles exhibited characteristic patterns depending on the process dynamics during early ...

Monitoring the performance of moisture purifiers for process gases

Problem Statement Moisture purifiers are a big aid in keeping moisture levels under control inside a process chamber. They are provided by manufacturers with certain life expectancies, which vary depending on the moisture content of the gas being purified. As a result, it is difficult to determine which gases have a high moisture content and which moisture purifier is becoming ...

Assessing Upstream Process Changes with ATP Monitoring

While the Biomass Stress Index (BSI) parameter is most often used to reveal when a biological population has been subjected to toxicity, it can also indicate when an upstream change has relieved a stressful condition. In this month’s featured case study, a pulp & paper wastewater treatment plant made a change to its papermaking process that changed the properties of the wastewater ...

Continuous monitoring of moisture present inside a process chamber

Problem Statement Moisture inside a process chamber is a big silent killer during wafer production. When production yield goes down, it is hard to pinpoint the source of the problem. Most of the time wafers need to be sent to labs for analysis, while production is stopped. If the problem is related to a high level of moisture inside the reactor, there are several factors that can cause ...

Solution for the processing of TV and PC monitors - Case Study

Bundles of power The disposal specialist L + N Recycling in Bubesheim had been trying to resolve a longstanding conflicting challenge: TV and PC monitor plastics should be compacted as tightly as possible for transportation, however, at the same time should remain in pieces that were large enough to be sorted later. The Bubesheim company found the solution in the HSM baling press. ...

Online Process Analyzer Installed at F.J. Horgan WTP to Monitor Chloramination

Construction was completed on the City of Toronto's F.J. Hor-gan Water Treatment Plant in 1979, more than 60 years after chloramine had first been used to disinfect drinking water in an Ottawa plant. By then there was little debate about the benefits of chloramination and it was incorporated into the new plant's design as part of the disinfection process. Chloramine is more stable than free ...
