Common failures & inspection points

Salinity electrode degradation and scale buildup

Clean salinity alarm electrodes to remove dust and scale deposits (monthly basis minimum)

Heat exchanger tube scale and salt deposit formation

Descale/clean interior heating tubes 2-3 times per year using physical or chemical methods

Reduced heat transfer efficiency due to scale formation

Monitor inlet and outlet temperature differential; inspect for scale if temperature loss exceeds specification

Ejector pump impeller wear and surface damage

Periodically inspect impeller condition for wear damage from high-speed revolution; replace if necessary

Vacuum system integrity loss

Monitor vacuum pressure readings and check water ejector seals and connections for leaks
