HUBER MCB installation in Berchtesgaden National Park
A blessing not only for marmots
Over thousands of years the mountain torrent Wimbach has carved a deep gorge into the solid rock. In many places spectacular water falls plunge down from the rock walls and collect in small pools, which are hollows formed by rocks carried along. Up to 100,000 people per year visit Berchtesgaden National Park situated in the impressive Wimbach valley, one of the three main valleys of the Berchtesgaden National Park.
In the middle of the valley lies the Wimbach castle, which in former times served the Wittelsbach rulers like prince regent Luitpold as lodge for their court huntings. Today the former castle houses a restaurant.
The challenges to be met when building a wastewater treatment plant in this beautiful nature included maximum effluent quality, minimum space requirements, and stable and easy plant operation requiring only a minimum of attendance by the restaurant owners who are after all fully engaged with their restaurant business. After a public tender HUBER SE received the order for a MCB size 3x2, which is able to handle about five cubic metres of wastewater per day with its membrane surface of 21 square metres. As the number of visitors strongly varies over the year, a buffer tank with an approximate volume of eight cubic metres was installed downstream of the settling tank and upstream of the membrane biology system to equalize the wastewater flow. The plant is switched into standby mode overnight to relieve the restaurant’s autarkic solar electricity system.
Since start-up in July 2009 the plant has survived a number of heavy thunderstorms and without problems handled the wastewater caused by even more visitors at the foot of the Watzmann. Only one night when a lightning almost struck the associated equipment unit, the plant operation was disrupted. However, wit 2000 h the excellent instruction provided by the HUBER service team this problem could soon be solved by the operators.
The HUBER business unit filtration & reuse is happy to contribute to the preservation of the nature in the Berchtesgaden National Park.
