Challenge Problems

Push your limits with challenges.

Question 1

In a water treatment process, the concentration of a contaminant in water is 200 mg/L and it needs to reach the air interface at 20 mg/L. If the mass transfer coefficient is known to vary, how would this affect treatment efficiency? Discuss potential solutions.

💡 Hint: Evaluate which parameters can be modified to influence mass transfer rates in the process.

Question 2

A study identified that increasing turbulence enhances mass transfer in a tank. Explain the underlying physical reasoning and its relevance to resistance.

💡 Hint: Think of the metaphor of pushing a mixer through thick paste.
