Fouling

The main purpose of this study is to evaluate a combined ozone and microfiltration (MF) membrane process as pre-treatment of a seawater reverse osmosis (SWRO) system. During the filtration of seawater (SW) with the MF membranes, membrane fouling on both hydrophilic (PHI) and hydrophobic (PHO) MF mem

Dairy ultrafiltration permeate (UFP) has been filtered using polyamide nanofiltration (NF) membranes in order to separate potentially valuable calcium and lactose from unwanted monovalent salts. An investigation into both the fouling and separation behaviour has been carried out to gather useful inf

The CSIRO Flagship Cluster project Advanced Membrane Technologies for Water Treatment is a collaboration of nine Australian Universities and the CSIRO looking at improving the energy efficiency of desalination of seawater using membrane processes. One of the initial aims of the cluster is to develop

Organic fouling and its effects on trace organic retention by three nanofiltration (NF) membranes were investigated in this study. Accelerated fouling conditions were achieved with foulant cocktails containing humic acids in a background electrolyte solution. The effects of membrane fouling on the s

A bench scale RO process simulator was operated in a batch concentration mode to determine the effects of product water recovery and feed water temperature on flux, rejection, and inorganic fouling by gypsum scale formation for simulated brackish water. As feed water temperature increased, salt reje

The effect of backwash frequency (15, 30 and 60 min) and influent flux (3.75, 7.50 and 11.25 L/h/m2) on fouling amelioration in an innovative external side-stream dead-end microfiltration anaerobic membrane bioreactor (AnMBR) for the treatment of domestic wastewater at 25EC was investigated. During

The effect that biofiltration had on the fouling behaviour of several commercial nanofiltration (NF) membranes used for drinking water treatment was investigated using a bench-scale set-up. A dual-media anthracite-sand biofilter was used to pretreat a humic acid-laden solution spiked with a solution

In order to determine the suitability of an ultrafiltration membrane module (OmexellTM SFP2660) to different feed waters, the filtrate quality and the operation status of the module were studied comparatively when it was fed with raw seawater, coagulated seawater and cooling tower blowdown (CTB) res

This pilot train study compares the biofouling potential of two river waters that had been subjected to different pretreatment schemes conducting to equivalent microbial cells contents but different total and biodegradable organic carbon concentrations. Permeability and pressure drop of nanofiltrati

Membrane methods, including MF, UF and NF, belong to high-efficiency processes which can be competitive with traditional methods of water treatment. However, their efficiency can be affected by some parameters such as rejection and permeate flux. In this work, three membrane processes (MF, UF and NF
