Home\Alternative Approaches to Replace Ozone and BAC in California DPR Projects

 Registration is closed for this event

Draft California DPR Regulations require a high degree of protection for unknown chemicals, chemical peaks and pathogenic organisms where at least four separate treatment processes and three diverse treatment mechanisms are needed. The article § 64669.50 (Chemical Control) requires DPR trains include Ozone and biologically activated carbon (BAC) prior to full advanced treatment for chemical control. While efficacy of Ozone-BAC for controlling chemicals has been well proven, inclusion of these additional barriers in a potable reuse train may further increase operational complexity, footprint and project costs which may shift interest of public agencies from DPR to IPR. Article § 64669.115 provides provisions to use alternatives if a direct potable reuse responsible agency demonstrates to the State Board that the proposed alternative provides an equivalent or better level of performance with respect to the efficacy and reliability of the removal of contaminants of concern to public health. In this Webcast, we will cover two alternative approaches that have great potential to replace Ozone-BAC in DPR projects without any substantial impacts on project cost, footprint and operational complexity.
