Membrane Fouling Control in Municipal Water Treatment: How to Clean Them Back.
This presentation describes a systematic approach to the examination of fouled membrane modules and the development and validation of preferred cleaning procedures, illustrated by case study data. Through experimental design […]
Increasing BWRO plant recovery using batch operation RO and a fluidized bed crystallizer
The developed system enables operation of an RO system with feed water varying in quality from 1 000 mg/L TDS to 70 000 mg/L TDS, and at water recoveries ranging […]
The Economics of Seawater Reverse Osmosis Desalination Projects
Desalination applications based on reverse osmosis (RO) technology today comprise over 50% of the capacity of all desalination systems worldwide and represent 75-85% of new desalination projects being implemented. The […]
California Ocean Plan Amendments: Applicability and Requirements for New, Expanded, and Existing Facilities
Although the City of Santa Barbara’s seawater desalination plant and intake are exempt from the Ocean Plan Amendments’ (OPA) requirements, the City has chosen to conduct its subsurface intake (SSI) […]
Membrane Technology for Blue Energy Production Using Water Salinities
Membrane technology has always been crucial to water purification process, but it could become the core element of energy generating system using salinity gradient. Reverse electrodialysis (RED) is one of […]
Energy Optimization with Energy Recovery Devices and Innovative Process Design Improvements with Applications in Membrane Systems
With advances in new RO membrane technologies only having minor energy reductions, reducing energy consumption by energy recovery devices (ERDs) and optimizing flow processes are the general approaches in desalination […]
Maximizing Energy Recovery from Brewery Waste Streams with Anaerobic Membrane Bioreactors and Biogas Conditioning
The New Belgium Brewing Company recently evaluated the effectiveness, reliability, and robustness of submerged anaerobic membrane bioreactor (AnMBR) technology at their Fort Collins, Colorado craft brewery. The pilot study drivers […]
A Case Study in Controlling Phosphate-Induced Scaling in Potable Reuse
In potable reuse, reverse osmosis (RO) is important for system-level salinity management and as a pathogen barrier in the treatment train. Scaling is a key driver of cost for RO […]
Membrane Surface Modification Using Quorum Sensing Inhibitors for Biofouling Prevention
Quorum sensing (QS) pathways regulate bacterial communication to trigger biofilm development, the main cause of membrane biofouling. Recent studies identified the integral role of QS inhibiting (QSI) compounds to disrupt […]
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 […]
