Drinking water treatment plants (DWTPs) need to be accepted according to current and future stringent water regulations (e.g. consumption of chemicals). Ultrafiltration (UF) can be appropriate technology to substitute and/or update conventional pre-treatment mainly for reverse osmosis (RO) in surface water treatment plants.
However, its long-term efficiency needs to be assessed at demonstration scale (with real surface water) not only in technical terms but also in environmental and economic ones.
The project has a total duration of three years (01 September 2010 – 31 August 2013), two of which are focused on the demonstration of the efficiency of three UF membrane configurations at prototype scale in parallel with the conventional pre-treatment installed in DWTP at Sant Joan Despí (Barcelona).
The impact of the above mentioned pre-treatments, both conventional and UF, on the subsequent RO step will also be assessed at pilot scale.
