Rejection of Perfluorochemicals (PFCs) by RO & NF Membranes: The Influence of PFC Chemistry, Membrane Type, Fouling & Feed Water Characteristics
The paper describes thesis research that elucidates the permeation mechanism of trace organics through Reverse Osmosis and Nanofiltration membranes. Specifically, the effects of size, charge and solute-membrane affinity on rejection (both time-variant and steady state) are investigated under varying feed conditions such as changing pH, ionic streng...
The Implications of Sorption on the Rejection of Pharmaceuticals & Personal Care Products by Nanofiltration
The purpose of this study is to show that the sorption tendencies of trace organic contaminants can have an effect on steady-state rejection....
Perspectives from the WateReuse Research Foundation and Big Spring, TX
Presents reuse in the context of WRRF approach on testing and monitiong (11-10 & 12-06) with a discussion on the actual results from the full scale plant at Big Spring TX....
Water Quality Evaluation at Big Spring, Texas
A municipal water district in Texas is purifying municipal wastewater effluent as a raw water supply for drinking water purposes. The process is MF, RO and AOP which uses both ozone and hydrogen peroxide. This project is the first USA direct potable reuse (DPR) system....
Case Study: Direct Potable Reuse in Texas
The advanced treatment plant that closes the loop on the first DPR project in the country consists of microfiltration (MF), reverse osmosis (RO), and a UV advanced oxidation process (AOP). This study examined the effectiveness of each process for removing a wide range of chemical and microbial constituents. MF acts mainly as pretretment for RO, but...
Membranes Getting Their Due: Progress Towards Log Removal Credit for RO Membranes and MBRs in Potable Reuse
Due to the increased popularity of potable reuse, demonstrated by the number of projects being implemented and proposed, the importance of membranes used in this application has risen. One of the biggest challenges to the application of any treatment technology in potable reuse applications is to demonstrate its effectiveness for pathogen removal, ...
Innovative Potable Water Purification without RO - Direct Potable Reuse Demonstration Pilot in Central Florida
The City of Altamonte Springs Potable Reuse Demonstration Pilot is an innovative treatment train in Central Florida which explores potable reuse without the use of reverse osmosis. The City aims at developing cost and process data for non-RO options for potable reuse in Florida, and assist the Florida Department of Environmental Protection in futur...
