9,75 m³/d, inn, Switzerland - Niederbauen
The Niederbauen mountain inn lies in the Swiss canton Nidwalden at roughly 1500 m above sea level and offers hikers the possibility of relaxation with an idyllic view of Lake Lucerne and the surrounding mountains. Besides a restaurant, overnight accommodation is also available.
Directly next to the house, there was an old septic tank whose odours were perceived to be increasingly unpleasant by the owners and visitors. With the KLARO One system, the existing single-chamber tank could be converted into a sewage treatment plant by adding only a few parts. This simplified transportation to the mountain inn which was accessible only by aerial ropeway.
Accordingly, sludge removal would also have been very problematic. For this reason, it was decided at that time to add a sludge dewatering module to the plant, which would be able to treat the entire sludge. This offers the advantage that the entire sludge can be treated with the sludge dewatering module. The sludge is pumped into a bag and dried. Later, it can be transported more easily.
