Question 1

What happens to sludge when rainwater is added?

  • It evaporates
  • It becomes a slurry
  • It remains the same

💡 Hint: Consider what mixing adds to the sludge.

Question 2

True or False: Equilibrium means concentrations change over time.

  • True
  • False

💡 Hint: Think about what equilibrium signifies.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
