Homogeneous, heterogeneous and biological oxidation may precipitate iron(II) as iron(III) hydroxides. In this paper we evaluate the conditions under which each of these processes is dominant in rapid sand filtration (RSF). It is demonstrated that in

Accurate detection of biofouling in membrane filtration installations is assessed by monitoring the feed channel pressure drop over individual membrane elements of a full-scale installation using a sensitive pressure difference transmitter. Feed chan

The relation between biofouling and membrane flux in spiral wound nanofiltration and reverse osmosis membranes in drinking water stations with extensive pretreatment such as ultrafiltration has been studied. The flux – water volume flowing through

Water quality parameters such as ATP, total direct cell counts, AOC, biofilm formation rate and destructive membrane studies are not suitable for biofouling monitoring and prediction. Therefore, a monitor named membrane fouling simulator was develope

A new tool–the Membrane Fouling Simulator (MFS) – is developed to measure membrane fouling (pressure drop increase) in a small and simple system, representative for spiral wound membranes applied in water treatment. With the MFS, fouling developm

Studies with a new tool — the Membrane Fouling Simulator (MFS) — illustrate that the MFS can be used to quantify and characterize fouling. Using the MFS, fouling can be monitored by (1) operational parameters like pressure drop, (2) non-destructi

A tool is developed for the validation of membrane fouling: the Membrane Fouling Simulator (MFS). The MFS uses the same materials as spiral wound reverse osmosis and nanofiltration membranes, has similar dimensions and hydrodynamic behaviour and is e

Vitens has six full-scale nanofiltration plants running successfully. Another one is under construction. Five of these plants are fed with anaerobic ground water with high levels of hardness, colour and/or sulphate. One plant treats bank filtrated IJ

In nanofiltration and reverse osmosis membrane systems 75–90% of the feed water is conversed to product, and as a consequence dissolved salts are concentrated in the membrane concentrate. Subsequently, sparingly soluble inorganic compounds such as

In three pilot plants in the Netherlands the performance of either nanofiltration or reverse osmosis in water treatment was studied. Operational problems observed in these systems, viz. increased normalized pressure drop (NPD) and/or declined normali
