Performance of an integrated granular media – ultrafiltration membrane process for drinking water treatment
This paper presents a novel approach to reducing the problem of ultrafiltration (UF) membrane fouling. It specifically considers the application of coagulation/sedimentation pre-treatment prior to UF for drinking water supply. […]
Removal of Fluorides, Arsenic and Nitrates from Groundwater: Technology Selection
An engineering study was conducted comparing reverse osmosis and activated aluminum filters for most cost effective removal of fluoride, arsenic and nitrates from a City of Goodyear Arizona well source. […]
HAOPs Pretreatment to (Nearly) Eliminate UF Fouling by NOM
Pilot and lab tests were ran to prove effectiveness of HAOPs for removal of Natural Organic Matter (NOM) from surface waters. HAOP can be used as an adsobent in a […]
Zeolite-embedded Polyelectrolyte Composite Membrane with Enhanced Performance for Forward Osmosis
This paper describes a layer-by-layer (LbL) method to sandwich Linde type A (LTA) zeolite nanoparticles between two polyelectrolytes, polyacrylic acid (PAA) and polyethylenimine (PEI), on a polyacrylonitrile (PAN) support layer. […]
Fighting permeability loss with a revised recovery cleaning schedule
This paper analyses the impact of a revised cleaning schedule based on the permeability of the membranes and the financial impact of increased chemical usage. A side-by-side comparison was conducted […]
