Copper(II) salts have long been used to kill algae in water systems, but they can precipitate as insoluble salts and form deposits on equipment surface. It is important to remove toxic metal from industrial waste because of contamination and toxicity issues. This paper discusses the testing and effects of various phosphonates to control copper-based fouling in the industrial water systems. It h...

Detection of Low Frequency (around 40kHz) Ultrasound is a powerful method for maintenance inspection of plant and machinery. Many failure conditions give early indication by the production of ultrasound. These include pressure leaks, electrical discharge and deterioration of bearings and other machinery. Leakage of compressed air has become a particular issue recently with the promotion of ener...

The use of state-of-the-art real-time techniques in industry remains infrequent. The reason for this, we believe, is three-fold: (1) the lack of commercially available tools, (2) the lack of methodologies based on real-time theory throughout the complete development process, and (3) the lack of competence in real-time theory among industrial practitioners. In this paper we present a case study ...

Engineers often cope with the problem of assessing the lifetime of industrial components, under the basis of observed industrial feedback data. Usually, lifetime is modelled as a continuous random variable, for instance exponentially or Weibull distributed. However, in some cases, the features of the piece of equipment under investigation rather suggest the use of discrete probabilistic models....

In the move towards world-class manufacturing, many firms are realizing a need for the use of proper maintenance of production facilities and systems. Industrial plants, machines and equipment are becoming technologically more advanced and at the same time more complex and difficult to control. Therefore, the importance of the maintenance function has been greater than before, due to its role i...

The overall performance of industrial conveyor systems for bulk depends on the reliability of individual system components and their arrangement. A model for dimensioning of large scale systems in the early design stage is discussed. In the model discrete event simulation is used for the modelling of equipment reliability and simple numerical integration is applied for the stacking and loading ...

This paper investigates the negative effects of electromagnetic interference (EMI) due to fast switching power devices (high dv/dt and di/dt) used in power electronic converters and industrial equipment. Mitigation techniques have been explored to reduce EMI noise effectively. Remedial measures to reduce the risk of equipment malfunction and health risk due to EMI have been explored. In this pa...

Equipment replacement is a fact of life in every industrial setting, and this paper seeks to answer the question: How can firms and policy makers effectively balance environmental and economic concerns with respect to replacement decisions? A replacement model which includes both economic and environmental factors is presented. One must decide whether to keep the existing technology, upgrade to...
