Question

The EPA requires hazardous waste incinerators to meet a standard of 99.99% destruction and removal of hazardous constituents injected into the incinerator. Determine the allowable quantity of contaminant in the exit stream if the incinerator is burning 1.0000 g/s of hazardous constituent.

If the incinerator is 90% efficient in destroying the hazardous constituent, what scrubber (which injects water into the process) efficiency is required to meet the standard?

Any help is appreciated, thank you!
