Novel Pneumatic System for Lime Dosage in Water Treatment Application

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.
