Coagulation-Bubbling-Ultrafiltration: Effect of Flocsand Bubbles Properties on the Performance of the Hybrid Process
This paper describes a novel hybrid process of coagulation-bubbling-ultrafiltration to study membrane fouling phenomena by surface water. The relationship of bubbles, flocs and the hollow fibers was explored.
Llobregat River Direct Ultrafiltration and Reverse Osmosis: Operation and Optimization Experiences
This paper describes the use of an integrated membrane system consisting Ultrafiltration (UF) and Reverse Osmosis (RO) filters treating raw river water that has been optimized by improving the operating […]
Performance of Commercial Asymmetric Cellulose Acetate Membrane Compared to Polydopamine Modified Thin Film Composite Membranes for Forward Osmosis
In forward osmosis applications the cellulose acetate (CA) membrane offers the best performance but carries the limitation of not tolerating a basic feed water. This characteristic eliminates the CA membrane […]
Developing The Stainless Steel Standard For Desalination and Water Industry Applications
There are many grades and types of stainless steel and stainless steels are used extensively in brackish and seawater membrane treatment facilities. Stainless steel corrodes when the wrong grade or […]
An Evaluation of the Impacts to Membrane Filtration under the Influence of TOC, MIB, and Geosmin
The paper and presentation is of interest to utilities that are challenged by total organic carbon (TOC), Geosmin, and MIB in their source water and are considering the use of […]
Impact of Naturally Occurring DOM, Colloids, and Cation Interactions on Nanofiltration of Pharmaceutically Active and Endocrine Disrupting Compounds
The occurrence, fate and ecotoxicology of emerging organic micropollutants including pharmaceutically active compounds (PhACs), endocrine disrupting compounds (EDCs), and personal care products (PCPs) have been of interest in recent years. […]
A Novel Application of the Tertiary Membrane Bioreactor Technology for Water Reuse – A Comprehensive Pilot Testing
Membrane bioreactors (MBRs) combine secondary treatment and solids separation in one system that produces high quality effluent with virtually free of solids. Coupled with widely used biological nutrient removal (BNR) […]
Increasing Reuse Supplies by Blending Nano Concentrate with Treated Effluent
The Loxahatchee River District (LRD) was one of the first large utilities in Florida to produce 100% reclaimed water in the 1980s. LRD’s overal wastewater management strategy is to provide […]
Know When to Hold ?em, Know When to Fold ?em. How Long Will Low Pressure Membranes Last?
As a major investment, membrane life has a significant impact on the life cycle cost of a treatment facility with the key to optimum performance is the right balance between […]
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. […]
