Model-Supported Design, Testing, and Implementation of Process Control Strategies. in: Smart Water Utilities: Complexity Made Simple
Abstract: Advanced process control has the ability to allow the full performance potential of your wastewater treatment plant to be realized by taking advantage of existing but unused capacities. In plants that are nearing their capacity limits this can lead to improved effluent quality and process stability. In plants that are under capacity, advanced control can allow you to operate your plant ...

eBook Titles from IWA Publishing: Free to Download - Volume 2
Process stability and final effluent quality largely depend upon the composition of the biomass in an activated sludge plant. Operational problems such as bulking and scum formation occur when the wrong micro-organisms are dominating the sludge population. Microscopic sludge investigation is therefore essential for process control and stable plant operation. The manual outlines the theoretical ...

Analysis of an Aseptic Process and Defining a Cleaning and Sanitization Plan
Abstract Cleaning and disinfection plans are a complex strategy to manage contamination risk in classified areas. Production residues (powder, oil, salts, etc.) and personnel-related contamination risk (production line in isolator, RABs, open line) should be e1aluated first before preparing and implementing cleaning and disinfection plans. The key aspects of decontamination should be defined ...

Comparative studies of control charts for torque data in automotive component assembling
This paper originates from a real case study, in which the torque required for assembling automotive components has to be monitored. Since the data collected are truncated from below, this paper compares three different methods to design control charts for truncated data. The first method is the I-MR control chart. The second and third approaches proposed in this paper are based on estimating ...

Analog Signals: Current vs. Voltage
Before 4-20mA devices, pneumatic systems were the gold standard for analog process control in the early 20th century, using compressed air or unreactive gases to monitor various parameters such as temperature, humidity, tank levels etc. They could transmit signals relatively long distances, were inexpensive for the time, and had low flammability risks. While the pneumatic techniques are still ...
