In this study, guidance is provided for applying microfiltration (MF) and ultrafiltration (UF) membranes to treat full-scale granular media filter (GMF) backwash water at drinking water plants. An example from the City of Melbourne in Florida is presented with the current approach to backwash water management at the full-scale along with a proposed approach to …

Analysis and Removal of Contaminants of Emerging Concerns from WWTP Primary Effluent by Novel MF/RO Treatment Process Pilot Study
Cal Poly Pomona, Carollo Engineers, Inc., and Pall Corp. are participating in a water reuse research funded by Bureau of Reclamation to evaluate novel treatment train ?integrated membrane anaerobic stabilization (IMANS)? system for wastewater treatment and water reclamation, the performance of microfiltration (MF) and reverse osmosis (RO) of primary effluent in Inland Empire Utility Agency …
Backwash Free Ultrafiltration for Silicon Wafer Production Wastewater Recycling
The semiconductor industry uses 1,500 gallons of ultrapure water to make a single 300 mm silicon wafer which generates a high volume wastewater stream high in silicon and turbidity. Using ultrafiltration that is backwash-free (air scour only) to recycle the waste stream has proven to be equally as effective as backwash and air scour. The …
Beenyup Advanced Water Recycling Plant: The Perth, Australia Groundwater Replenishment Scheme
This paper presents the Water Corporation of Western Australia’s strategy includes the construction and operation of the Beenyup Advanced Water Recycling Plant, which will transform wastewater effluent into recycled water meeting all drinking water related standards and guidelines. The facility is planned to start up in 2022 with advanced water treatment and ground water replenishment.
Carlsbad Water Recycling Facility Expansion: Design, Permitting, Startup, and Operations
The Carlsbad Water Recycling Facility (CWRF) is owned by the Carlsbad Municipal Water District (CMWD) and operated and maintained by Encina Wastewater Authority. Located in Carlsbad, CA, the CWRF treats secondary effluent from the adjacent Encina Water Pollution Control Facility to produce up to 4.0 mgd of Title 22 recycled water. The CWRF was constructed …
