Town of Walkersville, Maryland Integrated Membrane Water Treatment Plant
The Town of Walkersville (Town) is located in Frederick County in northern Maryland. The ground water wells were known to be under the influence of surface water. In 1999, a […]
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 […]
Regional Brackish Water Reclamation Program Feasibility Study
The Water Replenishment District of Southern California (WRD) is responsible for managing and replenishing both the West Coast and Central Coast groundwater basins. In the West Coast Basin, a significant […]
Water Reuse Optimization in the Paper Industry with Ceramic Membranes
Water is an essential for a better life and a critical resource for the pulp and paper industry and Kimberly-Clark (K-C) because all our products require some amount of water […]
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 […]
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 […]
A Novel Method for Modeling Brine and Permeate pH in RO and NF Systems
Concentrate pH in RO and NF applications plays a significant role in the formation of certain scales and the rejection of various contaminants. Incorrectly predicting pH can lead to excessive […]
Breaking the Chains to PFAs Concentrate Disposal
In 2016, EPA released a 70 ug/L health advisory level (HAL) for perfluoroalkyl and polyfluoroalkyl substance (PFAS) compounds within drinking water. Due to their persistence, removal of these compounds is […]
Push It to the Limit with High-Recovery Closed Circuit Reverse Osmosis and Flow Reversal Reverse Osmosis
This paper describes the results of pilot testing Closed Circuit Reverse Osmosis (CCRO) and Flow Reversal Reverse Osmosis (FRRO) technologies in an existing brackish groundwater treatment plant to increase membrane […]
