How The City Of Fallon Improved Sodium Hydroxide Dosing Reliability

Maintaining consistent pH levels is vital for optimizing coagulation and filtration processes, particularly when treating water for arsenic removal. Many facilities rely on high-concentration sodium hydroxide for this adjustment, yet traditional diaphragm pumps often struggle with the viscous nature of the chemical, leading to frequent priming issues and high maintenance demands.

The City of Fallon addressed these reliability gaps by transitioning to a duplex peristaltic metering system. Unlike traditional designs, these peristaltic pumps utilize a low-shear pumping action and high suction lift to ensure a steady chemical feed without the risk of gas-locking or loss of prime. The modernization also introduced safety-focused features like automated tube failure detection and tool-free maintenance assemblies, which significantly reduce downtime. This approach not only stabilized the dosing process but also optimized the facility’s footprint through a compact, wall-mounted configuration.
