Are any pretreatment technologies alone effective enough to remove pesticide active ingredients and priority pollutants, or must they be used in combination with other technologies?
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 systems sampled by EPA, removal of pesticide active ingredients was observed during pretreatment steps. For example, emulsion breaking typically occurs at conditions of low pH and high temperature, which may also hydrolyze some pesticide active ingredients. An equivalency demonstration such as the one described in Chapter 7 of the P2 Guidance Manual would be required for any pretreatment technology that a facility wished to use as the primary treatment technology for a pesticide active ingredient. A facility that currently operates an activated ca
