Scrubber - Wash Water pH Check
Open-loop scrubber wash water pH + PAH + turbidity compliance per MEPC.340(77).
Status
Compliant
Formula, assumptions, and limits
pH ≥ 6.5 at 4 m radius in ambient seawater. Discharge stops if too acidic. Some ECAs (Singapore, China) ban open-loop discharge - switch to closed-loop or LSMGO.
