Experimental Design Study of Reinforced Hollow Fiber Membrane Casting
There have been numerous articles published on formulating and casting unreinforced hollow fiber membranes. However, there are far fewer reports on preparation of reinforced PVDF hollow fiber membranes. Consequently, there has not been much study on key process parameters affecting reinforced hollow fiber membrane quality. We recently completed an experimental design study on casting reinforced […]
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, and climate change. While the RO process produces 75% to 85% of fresh water, 15% to 25% of the feed water becomes a waste stream […]

Automated Conductivity Profiling of Reverse Osmosis Units for Integrity Verification
Recent activity in the potable reuse field incorporates reverse osmosis (RO) processes as a requirement to provide pathogen removal and a reduction of other compounds. California has implemented the 12-10-10 log pathogen removal requirement respectively for virus, Giardia, and Cryptosporidium for proposed groundwater recharge projects. Reverse Osmosis (RO) integrity may be determined with measurements from […]

NF/RO Membranes Ability to Remove 1,4-Dioxane From Water Sources Used for Drinking Water Production
As research advances, compounds contained in water resources are being identified and regulated for removal during treatment chain for drinking water production. This is closely linked to the evolution of analytical techniques that allow these molecules to be detected and quantified at ever lower concentrations.

The Influence of Chirality on the Removal of Ibuprofen in a Nanofiltration Membrane Process
Multifunctional Nanocomposite Membranes: A Sustainable Environmental Remediation Approach
Since its inception, nanotechnology has shown considerable promise to tackle some of our most daunting societal challenges. Poor water quality is one such issue, and it can potentially be ameliorated through the application of intelligently designed nanostructures. Some of the most basic attributes of nanomaterials, such as their stability, extremely high surface area to volume […]
