Computational Fluid Dynamics (CFD) Modeling of Novel Designs for 3D-Printed Spacers in High-Pressure Membrane Modules
In the recent decade, 3D printing technology has been used to produce spacers in the membrane industry due to its advantages at dealing with complicated geometries and simplifying the assembling […]
Case Study: The Use of a Novel Antiscalant to Prevent Iron Fouling in a Brackish Water RO System
A municipality in Texas had been operating its new reverse osmosis (RO) trains for only a few months when it started experiencing severe decline in flux and an increase in […]
Industrial Reuse of Wastewater with Abrasive Solids Using Ceramic Membranes
The recycle and reuse of wastewaters for industrial applications has been around for a long time. Recent environmental, regulatory, and economic developments have made it essential for Companies to consider […]
Optimization of Ceramic Ultrafiltration Membranes for Stormwater Treatment and Trace Megal Removal
Stormwater in urban watersheds is often contaminated with suspended solids, oil and grease, and various metals, and ceramic membranes may offer a robust option for treating all of these. In […]
Dissolved Silica, Calcium, and Nutrient Removal From Reverse Osmosis Concentrate by the Diatom-Based Photobiological Treatment
Reverse osmosis (RO)-based treatment of brackish water and recycled water is one of the key solutions for solving the global challenge of water scarcity due to excessive drought, population growth, […]
Evaluation of an Integrated Tertiary Treatment System for Ultra-Low Level Phosphorus Removal in Hayden, Idaho
The Hayden Wastewater Treatment Plant process consists of a headworks, equalization, enhanced biological nutrient removal, oxidation ditches, and secondary clarifiers. The facility produces typical effluent total phosphorus (TP) concentrations in […]
Comparative and Challenge Testing of LPRO Membranes for PFAs and Emerging Contaminant Removal
Per- and polyfluoroalkyl substances (PFAS) continue to gain attention as potential health concerns, with the EPA intending to evaluate perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) for potential maximum contaminant […]
Embrace the Solids – Rethinking How Pretreatment is Used with MF/UF Membranes
Conventional wisdom would dictate that as raw water Total Suspended Solids and Turbidity rises, the head-loss across a filter or trans-membrane pressure (TMP) of a membrane filtration system should also […]
Concentrate Disposal Considerations for In-Land Desalination: A Comparison of Case Studies from Florida and Texas
CFD Modeling Studies and Empirical Comparison of Performance in 3D Printed Spacers in Spiral Wound Membrane Elements
Conventional plastic mesh material has been utilized as the feed spacer between spiral wound membranes sheets since they were invented. Under a grant from the Defense Advanced Research Projects Agency […]
