This paper presents the design and implementation of a supervisory control and data acquisition (SCADA) system for automatic fault detection. The proposed system offers advantages in three areas: the prognostic capacity for preventive and predictive maintenance, improvement in the quality of the machined product and a reduction in breakdown times. The complementary technologies, the Industrial Internet of Things (IIoT) and various machine learning (ML) techniques, are employed with SCADA systems to obtain the objectives. The analysis of different data sources and the replacement of specific digital sensors with analog sensors improve the prognostic capacity for the detection of faults with an undetermined origin. Also presented is an anomaly detection algorithm to foresee failures and to recognize their occurrence even when they do not register as alarms or events. The improvement in machine availability after the implementation of the novel system guarantees the accomplishment of the proposed objectives.

The sequencing batch reactor (SBR) technology possesses a high process flexibility and treatment efficiency. Unfortunately, up to now most SBR plants are still using fixed time-based sequential control (TSC), which can not react flexibly. Therefore, this paper will focus on instrumentation, control and automation (ICA) for SBR plants, because with the help of modern supervisory control and data acquisition (SCADA) systems and dynamic RTC it is possible to operate SBR plants much more effectively.

The application of automation and supervisory control and data acquisition (SCADA) systems to municipal water and wastewater treatment plants is rapidly increasing. However, the application of these systems is less frequent in the research and development phases of emerging treatment technologies used in these industries. This study involved the implementation of automation and a SCADA system to the submerged membrane adsorption hybrid system for use in a semi-pilot scale research project. An incremental approach was used in the development of the automation and SCADA systems, leading to the development of two new control systems. The first system developed involved closed loop control of the backwash initiation, based upon a pressure increase, leading to productivity improvements as the backwash is only activated when required, not at a fixed time. This system resulted in a 40% reduction in the number of backwashes required and also enabled optimised operations under unsteady concentrations of wastewater. The second system developed involved closed loop control of the backwash duration, whereby the backwash was terminated when the pressure reached a steady state. This system resulted in a reduction of the duration of the backwash of up to 25% and enabled optimised operations as the foulant build-up within the reactor increased.

Understanding Business Process needs is critical to successful implementation of new Information Technology. Understanding Information Technology capabilities is critical to successful evolution of Business Processes. Supervisory Control and Data Acquisition (SCADA) systems have been in the gas industry since the 1960’s. Earlier systems provided some data or information from the remotely controlled locations and a few key inter-connections. Now, sophisticated networked systems which contain layers of information detail from field devices and other computerized processes, feed simulators designed to study the process, use expert systems to advise on capability, and provide excellent data and information retention and retrieval tools. The potential to automate business processes is more complete than ever before. Computers can now help to manage integrated business processes where important data and information is moved regularly from one business process to another under the watchful eye of validation steps, at specified frequencies, with all the necessary reporting to process workers about the health, and performance, of the business process, process links, and the computer system. The business must understand the benefits and constraints which technology offers to a business process, and find ways to evolve the process with the new technology in hand. The IT manager must understand the business process needs in order to provide the appropriate technology to enable the business process with quick-change capability when change is indicated. This paper explores some of the relationships between the business process, and the technology impacting the process, on the way to producing a flexible, enduring, and friendly SCADA network, ready to interact with other SCADA systems, other internal processes, and the external world.
