Dusseldorf, September 26, 2002 -- Wedeco AG Water Technology has a new contract to supply the Lengries sewage treatment plant with an ultraviolet system for the disinfection of wastewater.
The plant will be operational in the spring of 2003 and is part of the Bavarian government's ambitious program to improve the bathing water quality of the upper Isar.
The upper Isar between Sylvensteinsee in the south and the southern suburbs of the Bavarian city of Munich is an extremely popular local recreational area in the summer months.
In the past, however, the permissible highest concentration of coliform microorganisms was frequently exceeded. A risk of infection could not be excluded. For this reason the regional authorities pronounced a ban on bathing in many places.
In a project which is unique in Germany and Europe, the water quality of the Isar will be improved by the targeted disinfection of wastewater in sewage treatment plants along the river, so that unrestricted bathing will be possible in conformity with the EU bathing water directive. The treatment of wastewater with UV light immediately inactivates pathogenic organisms, viruses and bacteria.
After Bad Tolz, Lengries is the second Isar municipality that has decided to take a WEDECO system in the context of the environmental project. Wastewater is disinfected with a TAK 55 system in the Bad Tolz sewage treatment plant. The positive experience gained with this system in the past months ultimately led to the decision to rely on the WEDECO technology in Lengries.
Other municipalities in the Isar region will soon be deciding whether to install a UV system in their sewage treatment plants in the future. In the autumn of this year, for example, the bidding period for the sewage treatment plants in Penzberg and Bendiktbeuren/Bichl expires.
WEDECO AG, with its headquarters in Dusseldorf, has branches in 17 countries distributed over all continents. It has production sites in Germany, the USA, Italy and Korea. WEDECO AG is a manufacturer of chemical-free water treatment systems based on ultraviolet light and ozone.
More than 200,000 systems represent a saving of more than 100,000 tons of chlorine each year and therefore make a considerable contribution to environmental protection.
