Using EDXRF to quantify the amount of Metals in Asphalt Binders

This article reviews these sources and proposes a scheme for measuring and quantifying the amounts of metals in their source materials used to bind asphalt used in making roads. The use of bench top EDXRF to characterize binders before blending them into asphalt cements is possible because the metal values are in the 10s – 1000s of ppms and are readily monitored. ...

Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

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 ...

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. ...

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 ...

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 ...

Monitoring the fate of fluorescing substances recycled in ultrafiltration process backwash water

The fate of fluorescing substances during the recycling of membrane backwash water (MBWW) ahead of coagulation, flocculation and sedimentation (CFS) with ultrafiltration (UF) membranes has been investigated. Bench-scale UF membranes were used to generate MBWW from a CFS-treated surface water containing 21 mg/L dissolved organic carbon (DOC) registering a 0.95 cm–1 UV254 absorbance that ...

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 ...
