3 cards from this section. Quick, good the night before a test.
What is sludge?
Think about what waste might look like in a tank.
Define mass balance.
It ensures that nothing is lost in the process.
What happens to the concentration of contaminants when rainwater is added to sludge?
Consider how volume affects concentration.
True or False: Headspace in a container does not affect sample analysis.
Think about what happens when gases escape.
A waste tank contains 500 kg of sludge with a concentration of 150 mg/kg of contaminant A. If 300 liters of rainwater is added, calculate the new concentration of A in the aqueous phase, assuming complete mixing.
Use the formula C₁V₁ + C₂V₂ = C₃V₃.
Discuss how increasing the volume of headspace in a sampling bottle alters the concentration of volatile contaminants. Use a specific example.
Consider the relationship between vapor pressure and volume of air.
