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 […]
Full-Scale RO 3+ Log Removal of Virus Surrogates Using Native and Spiked Molecular Markers and Condusctivity Profiling
Advanced treatment trains for potable reuse in California are required to demonstrate high log removal values (LRVs) for Giardia, Cryptosporidium, and enteric viruses. Reverse osmosis (RO) is a key treatment […]
Quantifying the Mechanisms Contributing to Pathogen Removal in Membrane Bioreactors
The purpose of this study is to understand virus removal mechanisms prior to the membrane in membrane bioreactors (MBR). This presentation will quantify the mechanisms that contribute to virus removal […]
Flux and Antifouling Performance of Bioinspired Liquid-Infused Membranes
Over the past few decades, the use of ultrafiltration (UF) membranes for water treatment and wastewater reuse has increased. However, the accumulation of bacteria on the surface of the membrane […]
The Influence of Complex Ions in High Recovery and Brine Concentrator Saturation Calculations
As RO systems are pushed to increasingly higher recoveries, the concentration of salts in solution increases exponentially. This drastic increase in salt concentration demands more complex scaling calculations for proper […]
Response Surface Modeling for Reverse Osmosis Remediation of Wastewater Containing Energetic Compounds
Hitting a Moving Target – Designing an MBR System with Uncertain Nutrient Limmits
The Fort Mill Water Pollution Control Plant (WPCP) is currently permitted to treat a capacity of 3.0 mgd, with current flows closer to 1.3 mgd. Due to the proximity of […]
Using MBR for On Site Water Recovery in New Mexico – Challenges and Solutions
The Albuquerque Bernalillo County Water Utility Authority (Water Authority) is developing a state of the art on site water resources recovery plant, located at a shopping center in the uptown […]
Construction and Startup of a 7-Stage RO System at the Valencia Advanced Water Treatment Facility
The Santa Clarita Valley Sanitation District of Los Angeles County (SCVSD) provides wastewater conveyance and treatment for residential, commercial, and industrial users in theSanta Clarita Valley. The SCVSD sewage system […]
The Evolution of High Recovery Reverse Osmosis to Achieve 95%+ Recovery
Increasing regulatory requirements and disposal costs around the world, as well as ESG mandates and incentives for recycling, are prompting industries to reduce their water and energy footprint, and highlight […]
