“…and cavitation development [8][9] in most pump system components; tube or pipe, the water treatment plants require frequent maintenance scheduling that could lead to higher operations costs to sustain the dosing flow rate will cause the choke problem in the water flow and will reduce the dosing flow rate, while the pressure needed is increased. To counter this issue, the pneumatic system would be a great solution since the history of reliable mechanism have been discovered in some applications such as reduction of ballast tank sediment [10], aeronautical landing gear systems [11][12] and multi-pipe drilling technology [13]. For that reason, this research proposes a novel pneumatic mechanism that composes of the twocylinder column as the replacement for the pump system by utilising the air as the medium of transferring the water treatment mixture.…”

This paper proposes a new pneumatic mechanism for lime dosage in water treatment application. Conventionally, current water treatment system technologies utilising pump system, which requires scheduling maintenance of operation to avoid choke problem due to scaling development. The choke formation depends on the lime dosage concentration, which will be based on the time of operations. Technically, the pneumatic system uses such a hydraulic mechanism consisting of fluid, especially liquid oil, to operate, requiring higher maintenance costs. Based on these arguments, this research investigates the potential of replacing the pump system with an air pneumatic system for water treatment. For that reason, this study proposed a new design of pneumatic mechanism as the alternative solution for pump system. Several analyses have been performed from fluid mechanics to study the water treatment plant flow rate that could be competitive with the conventional pump system.

Trajectory tracking in electro-pneumatic systems poses a significant challenge due to the nonlinearity of their dynamics. This research aims to analyze the performance of various types of controllers for a laboratory-scale pneumatic system in terms of energy consumption and control efforts. By considering the mathematical relationships among system components, a precise gray-box mathematical model is developed based on experimental data. Subsequently, different linear model-free and nonlinear model-based controllers, is designed and their performances are compared by measuring tracking error, control effort, maximum overshoot, settling time, robustness against disturbances, and energy efficiency in the presence of severe disturbances. The effectiveness of these control methods is assessed through experimental tests and compared.
