About Short tons per day
The short ton per day (ton/d, US) equals 907.18474/86400 ≈ 0.010499 kg/s, the capacity unit for mid-size mining operations, smelters, and US water-treatment chemical dosing. A small gold mine may process 500-1 000 short ton/d of ore; activated-sludge wastewater plants dose chemicals in short ton/d. 1 short ton/d ≈ 0.010499 kg/s ≈ 2 000 lb/d.
About Pounds per day
The pound per day (lb/d) equals 0.45359237/86400 ≈ 5.249×10⁻⁶ kg/s, used in wastewater engineering for reporting biochemical oxygen demand (BOD) loads, nutrient loadings, and sludge production. US NPDES permits set effluent mass-load limits in lb/d; a municipal WWTP serving 10 000 people generates roughly 1 500-3 000 lb/d of dry sludge solids. 1 lb/d ≈ 5.249×10⁻⁶ kg/s.
