Implementation of an Integrated Membrane System to Expand Reuse – City of Phoenix Cave Creek Water Reclamation Plant
The Cave Creek Water Reclamation Plant (CCWRP) is one of three wastewater treatment facilities either owned or co-owned by the City of Phoenix (City). The 8 mgd facility was placed in operation in 2002 but was taken offline in 2009 due to slower than anticipated growth in the surrounding area. Due to resumed growth, the […]
Which Membrane to Choose? A Comparison of Ceramic, PVDF, and PES Ultrafiltration Membranes and Surface Water Treatment
Since 1953, Halifax County Service Authority (HCSA) has treated the Dan River using flocculation, sedimentation, and conventional sand filtration at their Leigh Street Water Treatment Plant. HCSA is interested in replacing the existing sand filtration system with ultrafiltration (UF) membranes to provide consistent, high quality drinking water for their plant, regardless of variability in the […]

Reversing the Flow – Full-Scale Design Considerations for Flow Reversal Reverse Osmosis
The City of Santa Monica has limited additional local water supplies available and is seeking the most cost-effective and sustainable technology capable of squeezing as much production as possible from the existing Arcadia Water Treatment Plant. Between June to December 2020, two high-recovery reverse osmosis technologies were piloted simultaneously in an existing brackish groundwater treatment […]

The First U.S. Installation of a BWRO Pressure Exchanger
Energy recovery technologies such as the pressure exchanger (PX), have previously focused on seawater RO applications due to the rather quick payback. This leaves brackish water RO (BWRO) facilities to turbochargers that yield less efficient transfer of energy than their PX counterparts. Recently, the first municipal BRWO application of a PX energy recovery device was […]
