Gut Aiderbichl (https://www.gut-aiderbichl.com/en/) has been working for animals since 2001 and is an important institution for animal welfare throughout Europe. More than 6,000 rescued animals live on our home farms in 6 European countries by now, rescued from the most diverse situations. Currently, 35 different species of animals live on our farms. The animal keepers care for them 365 days a year. Gut Aiderbichl sees itself as a meeting place for humans and animals.
An artificially created lake serving as a reservoir for fire protection, a biotope, and watering place for animals.Unfortunately, the lake´s design did not consider environmental aspects to keep the water in natural ballance which caused problem.
An old sewage treatment plant needed support for the process of oxidation/oxygen input.
The initial contact between Tsurumi/Pumpen Lechner and the municipal wastewater treatment station Hallau (ARA) in Switzerland was established at IFAT exhibition in 2018. The ARA Hallau is using R&O submersible aerators in their combined flotation and sand removal units and the customer was looking for alternatives to the R&O units as they are not satisfied with the products. One further goal was the decrease of the power uptake of the used units as the R&O products are supplied with 3 kW motors (rated power).
Removal of duckweed from the local drafting water reservoir. The water reservoir is used as an emergency water storage in case of fire. Thus, the water needs to be free of impurifications, so that the high-pressure fire-fighting pumps are not harmed in case that the reservoir would be needed in emergency cases. In the summer, a lot of additional duckweed grows in standing water. An exchange of oxygen is hindered by this, displacing animals and plants. This is prevented by suctioning away the duckweed. The reservoir has a surface area of approx. 500 m².
