About Million litres per day

The million litres per day (ML/d or MLD) equals 1000/86400 ≈ 0.011574 m³/s, the standard capacity unit for water-treatment plants, sewage-treatment works, and desalination facilities in the UK, India, and much of the Commonwealth. A small town water-treatment works processes 5-20 ML/d; the Beckton Sewage Treatment Works in London treats ≈700 ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.

About Millilitres per minute

The millilitre per minute (mL/min) equals 10⁻⁶/60 ≈ 1.667×10⁻⁸ m³/s, the standard flow rate unit for HPLC and preparative chromatography. A reverse-phase HPLC column (4.6 mm i.d.) operates at 1-2 mL/min; a cardiac output catheter measures 4 000-8 000 mL/min (= L/min). 1 mL/min ≈ 1.667×10⁻⁸ m³/s = 60 mL/h.
