Challenge Problems
Push your limits with advanced challenges
A treatment facility has a mixture of 600,000 kg sludge with 250 mg of contaminant A. If 800 m³ rainwater is introduced into the system, what is the new concentration of A assuming all other conditions remain stable?
💡 Hint: Use mass balance equations to guide your calculations.
The organic carbon content of the sludge is 10%. If 10% of the contaminants are bound to this carbon, how would this influence measurements if not accounted for?
💡 Hint: Consider how organic carbon binds to contaminants and the implications for data accuracy.
