|Water Characteristics of Brazil: The Need for Local Action|
Dr. Dipl.-Ing. Mag. Wolfgang K. Walter, Univ. Prof. Dr.-Ing. Wolfgang GĂĽnthert
Brazilâ€™s perception as a water nation, not meaning a national waterborne strategy, although the Brazilian fleet aims for a substantial upgrade in order to demonstrate Brazilian petrol interests most recently, is widely covered in the literature. Even up to 16 per cent of the worldâ€™s freshwater resources are said to be located on Brazilian territory.
|Long term experience with Germanyâ€™s largest membrane filtration plant for drinking water production (7,000 m3/h)|
Dr.-Ing. Stefan Panglisch, Dipl.-Ing. Walter Dautzenberg, Andreas Holy
Currently, around 100 membrane filtration plants are in operation in Germany, of which 85 % are operated with low pressure porous microfiltration (MF) and ultrafiltration (UF) membranes. About 90 % of the total number of plants uses spring and well water as a raw water resource and just 7 % are fed with reservoir water. However, related to the total capacity of roughly 325,000 m3 produced drinking water per day by porous membranes in Germany about 60 % is from reservoir water, meaning a lot of water is produced by a small number of large plants.
|Treatment of Waters Containing Humates with Ozone Biofiltration|
Dipl.-Ing.(FH) Manfred Brugger
In recent years, ozone biofiltration has established itself successfully in drinking water treatment applications. Practical examples in Germany, Scandinavia and the USA illustrate that with ozone biofiltration, it is possible to realise reliable and economical drinking water treatment plants. In addition to the fundamental basics, the results from an operational plant in Norway will also be outlined in this article.
|CPF Cast Surfaces Prove their Worth in Drinking Water Reservoirs|
Ltd. Akad. Dir. PD Dr.-Ing. Gerhard Merkl
According to EN 1508 , â€śService reservoirs shall be designed, constructed and operated to prevent contamination or other chemical, physical and biological changes that are detrimental to the water qualityâ€ť. Only approved materials shall be used in the surfaces in contact with the stored water. â€ś In order to facilitate subsequent cleaning and avoid bacterial growth, internal surfaces shall be as smooth and pore-free as possible.
|Innovative MultiboreÂ® UF Technology in a Municipal Wastewater re-use Plant|
Ralf Krueger, Hu Shaohua, Zhang Ruijin
The expansion of the Beijing Capital International Airport made it necessary to open up new sources for the water supply to the new facilities. The decision for reuse of effluent water from a municipal wastewater plant was mainly based on two reasons. The major reason is to save scarce groundwater. In addition, the idea of providing water using an innovative and economically friendly water re-use plant was strongly supported by the fact that the expansion of the Beijing Capital Airport coincided with the 2008 Olympic Games in Beijing.
