Llobregat River

The Llobregat is a 156 km long river, which supplies 35% of the Barcelona's drinking water needs from the Sant Joan Despí Water Treatment Plant. Since the establishment of the Salt Mine Works in the Llobregat basin in 1923, a progressive salinization of the water sources has been recorded. The operation of the Brine Collector, as a public work carried out by Aigües de Barcelona (AGBAR), started in 1989; it enabled a very significant improvement in the quality of the surface water used for drinking-water production.

Dissolved Air

Dissolved Air Flotation (DAF) has become increasingly important in the field of potable water treatment, as a preferred option for treating upland and stored lowland waters. This paper outlines the development of dissolved air flotation (DAF) in potable water treatment, the benefits and disadvantages and the recent advances that has taken the process technology from an art to a science.

Treatment Step

Most surface water treatment plants use floc-filtration as the most important treatment step in drinking water production. This paper presents a new technological development which allows floc-filtration to be carried out in pressure filters. Experiments in pilot and full scale show its high efficiency. The technological development allows us to treat algal-rich and high turbid matter containing raw water efficiently at high filtration rates. Floc formation can be realised by means of a special reaction tank in front of the filter inlet. Efficient removal of particles and turbidity is achieved if filtration with filter inlet flow controller is used.

Water Companies

About forty per cent of drinking water in The Netherlands is produced from surface water. Dutch water companies, that have to rely on this source, are dealing with major water quality problems due to the use of herbicides on pavements. Voluntary measures and bans have had only limited effect on the reduction of emissions of herbicides that runoff from pavements into surface water in The Netherlands. The effects on the production of drinking water from surface water should play a role in the authorisation of pesticides. Stricter regulations, including mandatory emission reduction measures and certification, are necessary. The enforcement of existing Dutch surface water pollution laws should solve part of the problem. Due to the international nature of most of the surface water used for drinking water supply, it is necessary that other countries take measures as well. European legislation brings a solution closer if implemented well and seriously enforced. The threat of strict legislation keeps pressure on the transition towards decreasing the dependence on chemicals for weed control on pavements.
