Sandtrap Issues
The WWT station of Freudenstadt suffered from the problem, that the installed pumps of another maker kept wearing out very fast in the challenging application of a sand trap. Due to the high percentage of sand in the medium to be pumped, normal sewage pumps in grey-cast-iron construction are in terms of material too weak to withstand the abrasion.

Desludging of a fish pond
10 acres of fish ponds faced the issue of decreasing water levels due to continuous sedimentation. The customer needed to remove the sludge from the ponds and while doing so, he wanted to increase the depth of the ponds. Instead of hiring excavators that would cost a lot of money and time, the customer turned to our Tsurumi partner in Hungary, Verbis.

wastewater treatment aeration
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).

Duckweed Removal
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.
Bulgaria
Wastewater on Military Base
The Novo Selo Training Area is a major Bulgarian military training facility established in 1962, presently used by other NATO nations as well. The range has a surface area of 144 km2 (55.6 sq. mi) and is situated 45 km from Bezmer Air Base and 70 km from the port of Burgas in Sliven Province, Bulgaria.
The facility has its designated areas and sectors for tank shooting, and nuclear, biological, and chemical defense and reconnaissance training. The Novo Selo Training Area is highly appreciated by NATO experts and troops and has become the favored site of annual joint US and Bulgarian troops exercises since 2004.
The Novo Selo Training Area is among the joint US-Bulgarian military bases established according to the 2006 Defense Cooperation Agreement between the United States and Bulgaria. The US Army started in late 2008 a 61.15 m USD investment in the development of new housing and other infrastructure for the American troops training at Novo Selo Training Area.
