Main Author: Amar Bhardwaj, Student, Columbia University, AMTA ADC 2018 FellowIn this research, thin-film composite reverse osmosis membranes are coated with nanofilms of silicon oxide, a novel material for this […]
Chlorine Dioxide for Removal and Prevention of Biofouling
Biofouling is a major problem in membrane operation in water purification. Ultra-pure chlorine dioxide is an effective chemical for removal and prevention of biofouling without damage to membranes. Intermittent dosing […]
Make the Old New Again by Converting and Upgrading with a Different UF Membrane
This paper presents the planning and execution of the conversion of three existing UF skids at a power generation station in Indiana. The approach was deliberately minimally invasive to minimize […]
Effects of Chloramines and Bromamines Residuals on RO Membranes in Potable Reuse
This paper will focus on brining an important issue of oxidative damage of RO membranes by the often overlooked bromamines residual that can form in waters containing high levels of […]
Understanding Specialty Chemical Cleaner Components and Their Specific Roles in Targeted Foulant Removal
Our abstract describes our goal to provide a thorough review of the different components commonly used in specialty cleaners. Professional Water Technologies has been serving the water industry with specialty […]
Novel Anaerobic Dynamic Membrane Biofilm Reactor Addresses Disadvantages of Conventional Anaerobic Membrane Bioreactors
Anaerobic membrane bioreactors (AnMBRs) provide many advantages for wastewater treatment and resource recovery from waste streams, and AnMBR research has grown exponentially in recent years. Studies have shown that AnMBRs […]
Challenges of Retrofitting a Conventional Wastewater Facility to Membrane Bioreactor Technology for Penn State University
Penn State University is the process of replacing their existing conventional activated sludge wastewater treatment facility with a membrane bioreactor facility. Facility upgrades are required to improve operational reliability, replace […]
Effects of Energy Recovery Device Reliability on the Operation and Costs of Seawater Reverse Osmosis Plants
In contrast to the many papers previously published and presented on energy recovery devices (ERD) in seawater RO systems, this presentation will consider the effects of ERD availability and reliability […]
Membrane System Design and Operating Basics People Don?t Talk About (Much)
The paper presents suggestions for improved design and operation of MF/UF treatment plants based on the author?s 35 years of experience. Suggestions include: 1. Derate Piloted Flux to yield more […]
MAXH2O Desalter Technology – Innovative Solution for Brine Minimization
Reject brine, with a high content of dissolved salts, is a by-product of the brackish water and industrial wastewater desalination processes. With the growing demand for water, increasing amounts of […]
