Expanding Reuse for Carlsbad, California, Using Membrane Technologies

The City of Carlsbad installed a 3.4 mgd UF facility to expand the reuse from the adjacent Encina Water Reclamation Facility. Water quality from the upstream wastewater plant resulted in various operational challenges during initial plant start-up. The plant operators and design-build team were able to adjust maintenance cleaning approaches and replace strainers to provide stable operation at design capacity, addressing challenges of operation with the secondary effluent.
