2 cards from this section. Quick, good the night before a test.
What is the mass balance principle?
Think about conservation laws.
What percentage of organic carbon is present in the sludge?
Recall the key figures from the sludge discussion.
What does mass balance ensure in a system?
Think about the law of conservation.
True or False: The organic carbon content in sludge does not influence chemical A concentration.
Consider its role in chemical binding and behavior.
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.
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.
Think about the nature and role of organic pollutants and their interactions.
