Challenge Problems
Push your limits with advanced challenges
An industrial facility has a waste tank that contains 600,000 kg of sludge with a concentration of 250 mg/kg of chemical A. During a heavy rain, 800 m³ of rainwater is added to the system. Calculate the new concentration of chemical A in the aqueous phase if it is assumed that no loss occurs during sampling.
💡 Hint: Be sure to use consistent units and remember to convert.
If organic carbon is present in the sludge, adding 10% of the original concentration to the aqueous phase, how does this affect your initial concentration calculations? Discuss the implications regarding pollutant containment.
💡 Hint: Think about the nature and role of organic pollutants and their interactions.
