DESTRUCTION AND REMOVAL EFFICIENCY (DRE)


Meaning of DESTRUCTION AND REMOVAL EFFICIENCY (DRE) in English

A percentage that represents the number of molecules of a compound removed or destroyed in an incinerator relative to the number of molecules entering the system (e.g. a DRE of 99.99 percent means that 9,999 molecules are destroyed for every 10,000 that enter; 99.99 percent is known as "four nines." For some pollutants, the RCRA removal requirement may be as stringent as "six nines").
