Challenge Problems
Push your limits with advanced challenges
Calculate the concentration of chemical A in a scenario where 500,000 kg of sludge has a concentration of 200 mg/kg. After adding 1000 m³ of rainwater, what is the new concentration if the total volume of the mixture is 600 m³?
💡 Hint: Use mass balance principles to find the new concentration.
If a facility wants to reduce the concentration of a pollutant in water from 300 mg/L to below 50 mg/L through dilution with rainwater (concentration 0 mg/L), how much more water must they add if they initially have 1000 L?
💡 Hint: Think of how dilution affects concentrations in mass balance calculations.
