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 Microlitres per second

The microlitre per second (µL/s) equals 10⁻⁹ m³/s, the working range of microfluidic lab-on-a-chip devices and nano-HPLC pumps. Organ-on-a-chip perfusion bioreactors, droplet microfluidic systems, and capillary electrophoresis instruments operate at 0.1-100 µL/s. A syringe pump delivering 0.36 mL/h produces exactly 0.1 µL/s. 1 µL/s = 10⁻⁹ m³/s = 60 µL/min.
