Enhanced and Accelerated Microbiological Monitoring for Membrane Treatment Optimization: Measuring the Benefits of an Optimized Monitoring Program
In this study, it was shown that proactive biological monitoring using advanced ATP was able to guide mitigation strategies and optimize design modifications for improved plant operation and water quality. […]
Design and Implementation of a Pacific Ocean Algal Bloom Challenge Pilot Test for the Carlsbad Desalination Project
Algae blooms in seawater present a challenge for desalination plants and are highly variable and are a function of several conditions arising from currents and upwelling; also they can vary […]
Open Intake RO Pretreatment for Harmful Algal Blooms
To meet the growing demand for water in arid areas, most large desalination plants have opted for open seawater intakes with media filtration or UF membranes prior to RO treatment. […]
Bacterial TEP Fouling on RO Membranes and Visualization of Agglutination between Bacterial TEP and Bacteria
Transparent-exopolymer-particles (TEP) are reported as a significant contributor to organic fouling of low pressure membranes and biofouling of RO membranes. TEP-like substances are generally synthesised from algae and bacteria, but […]
No Membranes without Oil, No – Last – Oil without Membranes
There is a global challenge to efficiently use water sources and opportunities with membranes in the oil production, refining, and petrochemical sectors. Membrane technology developments in these fields include produced […]
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 […]
At the Coal Face: Preventing Iron & Manganese Fouling of Brackish Water Reverse Osmosis Membranes
A containerized WTP using inside-out ultrafiltration as pretreatment to brackish water RO membranes with blending was built for treating mine influenced water prior to discharge to a local waterway. It […]
