Recovery of Adenovirus from Tap and Surface Water by Crossflow Ultrafiltration: Experimental Determination and XDLVO Predictions
This study examines the recovery of enteric adenovirus HAdV 40 by crossflow ultrafiltration from several water matrices (deionized water, tap water and surface water) and interprets recovery data by elucidating […]
Evaluating the Impact of Pasteurization Pretreatment on Membrane Performance at the Venturawaterpure DPR Pilot Facility
The City of Ventura, CA has taken a proactive approach to further advancing potable reuse as an alternative water supply, with the VenturaWaterPure Demonstration Facility serving as a critical component […]
The Yuma Desalting Plant – Past, Present and Future
Drought conditions and imbalances between supply and demand in the Colorado River watershed have demonstrated the need for the development of long-range measures to manage and stretch the system’s water […]
Analysis of the Impact of Citric Acid CIP Carryover on Disinfection By-Product Formation in Membrane Treatment Facilities
Contamination of membrane systems treated water from clean-in-place (CIP) chemicals is un-avoidable. Citric acid is of particular concern as it will react with chlorine disinfection in the downstream process resulting […]
Development and Application of New Methods to Measure Bacterial Activity and Nutrients in Seawater in Reverse Osmosis (SWRO)
ATP is a biomarker for biomass and can be used as a valuable indicator for biofouling. Until now, ATP in seawater could not be measured using luciferin/luciferase reaction due to […]
Energy Recovery Devices, Membrane Flux Balancing and Net Energy Consumption For Recycled Water – A Full Scale Evaluation
At the Orange County Water Districts Groundwater Replenishment System, 6 – 5 mgd Reverse Osmosis units have been recently installed to provide an additional 30 mgd of treatment capacity. The […]
The Use of Arabic Gum as an Additive to Polysulfone Membranes
Arabic gum (AG) as an additive to the casting solutions of polysulfone (PS) was investigated in this work to increase the hydrophilicity of PS ultrafiltration membranes. Various AG loading (0.1-3.0 […]
Passive Membrane Filtration For Drinking Water Treatment in Remote and Rural Communities
This paper discusses the long-term operation of a UF membrane system for drinking water treatment under ‘passive’ (i.e. without backwash, chemical cleaning and permeate pumping) conditions could be sustained over […]
Optimization of WWRO for Alamitos Barrier – Improving Performance Through More Aggressive Operation
The use of reverse osmosis (RO) to treat municipal wastewater for various reuse purposes has gained considerable momentum in recent years, with multiple facilities now exceeding 100 million gallon per […]
