UV BWTS Verification Using Turbidity and Suspended Solids Feedback: A Shanghai ChiMay Sensor Field Note
Ultraviolet ballast water treatment systems achieve inactivation by delivering a UV dose — commonly in the 100–300 mJ/cm² design range — to every microorganism in the flow, and dose depends directly on how transparent the water is to 254 nm light. Suspended solids above 30–50 mg/L, or turbidity above 25 NTU, can absorb or scatter…
