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 US quarts per second

The US quart per second (qt/s) equals 3.785411784×10⁻³/4 ≈ 9.464×10⁻⁴ m³/s, used in US industrial filling lines handling quart-size containers (motor oil, paint, sauce). A high-speed filling machine loading 1 qt bottles at 4 per second processes 4 qt/s per nozzle. 1 US qt/s ≈ 9.464×10⁻⁴ m³/s = 0.9464 L/s.
