The case study outlines the installation of Protoc TOC analysers at Manchester International Airport used for continuous surface water quality monitoring and control. The Protoc TOC instrument manufactured in the UK by Pollution & Process Monitoring Ltd was rigorously tested and was selected for a number of installations at critical drainage locations which have proved the reliability of the ...
Abstract: Principal components analysis (PCA) is a multivariate statistical (MVS) technology that can be applied in process monitoring and fault diagnosis. Dofasco has developed on-line multivariate statistical process control (SPC) monitoring systems for both its #1 and #2 continuous casters (#1CC & #2CC) based on this technology. The paper introduces the reader to the basic process of steel ...
This paper proposes a Variable Sampling Interval version of the Fixed Sampling Interval S2-EWMA control chart developed by Castagliola (2004) and dedicated to the monitoring of the sample variance of a process. In this paper, we explain how the various parameters of this VSI S2-EWMA control chart can be computed and how the use of the VSI feature significantly improves the statistical efficiency ...
Melt pressure is one of the most important process parameters in polymer extrusion and is closely related to product quality. However, it is not directly controllable and may be affected in a complex manner by changing other process operating conditions such as screw speed and barrel set temperatures. The ability to predict such parameters would be a powerful tool to aid process design and ...
Abstract In recent years, the FDA response to companies with insufficient proof of control over their production has become more aggressive, demonstrated by the rise in 483s and warning letters issued. Topics related to environmental monitoring programs are included in the most common reasons 483s are issued. By becoming aware of the regulations and reasoning backing 483 distribution, ...
The case study outlines the installation of Protoc TOC analysers at Heineken used for monitoring key effluent streams and proactively manage their site effluent. After ten years of continuous operation, the instruments are still performing reliably and are an integral part of the Company’s environmental compliance. The site has used the Protoc analysers to gain a better understanding of ...
Anglian Water (AWS) has selected the Proam ammonia monitor to provide continuous ammonia measurement on final effluent discharge where accurate and reliable measurement is required. One of the most recent installations is at Stanningfield WwTW situated near Bury St. Edmunds, in Suffolk. This is a small rural site receiving primarily domestic sewage. The site performs aerobic treatment in a ...
Viable, non viable particle counts: Environmental and Process Monitoring- Annex 1, Section 9.4 In Part 3 of our 5 part blog series, we look at Viable Non Viable (V/NV ) Particle counts regarding Environmental and Process Monitoring as found in Annex 1, Section 9.4: RA should be done to develop a comprehensive environmental monitoring program Sampling locations of cleanroom particle ...

Aerobic granulation from floccular sludge is difficult to detect in first stages with the naked eye. This work proposes a combination of multi-way principal components and case-based reasoning to predict the granulation state of a sequencing batch reactor, based solely on the on-line registered profiles of common sensors (i.e. pH, dissolved oxygen and oxidation-reduction potential). The ...
The ZE: 908 allows users to add a noise measurement capability to an existing process control system. The ZE:908 is a small, lightweight power supply and acoustic conditioning unit for microphone preamplifiers, it is ideal as a front-end for data logging and analysis systems where a simple and accurate acoustic input is required as an interface between an acoustic transducer and a process ...
Intellectual disability is common and lifelong, with lifetime cost. Thus, this people have been the focus of recent major national policy developments in Europe, the USA, Australia and across high-income countries. The education of these students with disabilities now can benefit from a wider range of assistive tools. Following this unstoppable trend, this paper presents MAS, a software platform ...
The ZE:908 is a small and lightweight power supply and acoustic conditioning unit for the Cirrus MV:200 microphone preamplifiers and MK:170 Outdoor microphone units. Many industrial plants have a variety of process sensors strategically placed around their site so that safety, environmental impact and efficiency can be monitored and managed, in real time, from one or more control rooms. The ...
DIAMOND is a 24-month ‘Research for SMEs’ European Union's (FP7/2007_2013) project that began in September 2012 and finished in August 2014. The project aims to achieve a model of excellence in the management of wastewater treatment systems by addressing the design, development, implementation and validation of new advanced data management, monitoring and control algorithms and tools ...
Sector: Distribution Number of Sites: 1 Audits Per Year: 5,000 + The Challenge To Migrate from a Plethora of Disjointed Auditing Formats Tesco’s distribution centre in Donabate, Dublin, Ireland is a 780,000 square foot facility with a handling capacity of 1.5m cases per week. It is currently the world’s eighth largest building. However the facility was relying on several ...
Mass spectrometry as a technique has grown significantly in recent decades, with many analytical requirements are addressed by mass spectrometry in some form or other. The techniques of ionisation, mass separation and detection are varied, and the process is now used in analytical sectors ranging from relatively simple vacuum and vacuum process monitoring to the more complex life sciences and ...
Woodside had been experiencing intermittent blockages in 4/5 S1406 LNG trains since September 2008 and had been unable to pinpoint the source of the problems. Repeated hydrate formations were leading to reduced productivity and the existing process monitoring instrumentation had failed to confirm moisture breakthrough on the beds. The site's existing Panametrics portable moisture analysers had ...
The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of data acquired. Since real-time data is likely to contain a certain amount of anomalous values and data acquisition equipment is not perfect, it is essential to equip the SCADA (Supervisory Control and Data Acquisition) system ...
Three large wastewater treatment plants in Sweden participate in a project evaluating different types of ammonium feedback controllers in full-scale operation. The goal is to improve process monitoring, maintain effluent water quality and save energy. The paper presents the outcome of the long-term evaluation of controllers. Based on the experiences gained from the full-scale implementations, a ...
