Consideration of District Alternative Treatment Technology for the WRF: Membrane Bioreactor in place of Approved Oxidation Ditch Technology
Document Type
ADM - Addendum
Document Description
Note: Addendum The District has proposed constructing a wastewater treatment and reclamation facility (WRF) and sewer collection system known as the Wastewater Reclamation Facility Project (the "Project"). Following the District's adoption of a MND, the District proceeded with the detailed engineering needed to construct the Project. As the Project has progressed, more detailed engineering has identified an alternative wastewater treatment system for use at the WRF known as "Membrane Bioreactor (MBR)" treatment technology. The District originally proposed an Oxidation Ditch treatment process that requires the use of medial filtration. The details of this system are provided in Addendum No. 2, but the District has concluded that a MBR treatment system, in place of the Oxidation Ditch followed by media filtration, would better meet the water quality objectives of the District.
