When performing emulsion breaking, won the removal of the oil/scum layer remove organic pollutants?
Yes. The oil/scum layer removed during emulsion breaking typically contains some level of organic pollutants, and may also include organic pesticide active ingredients. During treatability tests conducted by EPA on wastewater collected from PFPR facilities, the emulsion breaking step typically lowered the pesticide active ingredient concentration in the remaining wastewater. However, it did not typically reduce the pesticide active ingredient concentration enough to be considered an adequate pesticide active ingredient treatment technology. In general, pretreatment technologies are meant to be used in conjunction with the pesticide active ingredient destruction and removal technologies listed in Table 10, or other technologies demonstrated to be equivalent to those listed in Table 10. However, it is possible that some technologies that EPA has identified as pretreatment technologies can provide treatment equivalent to the technologies listed in Table 10. In many of the treatment system
