Explanation of the StingR® plant

Interview: World first in filter technology

functioning of the
StingR® filter unit

To Video

The filter element is flooded with the dirty medium.

The dirt is collected by the filter elements and the filter cake builds up.

The clean medium is immediately available again.

A backwashing by pressure pulse is triggered by a pressure differential, and reactivates the filter surface.

Unique technology
for tailored applications

For millions of years, our world has been surrounded by huge areas of water.
Oceans cover more than two thirds of our planet and are essential for life on earth.

Water is the basis of all life and therefore more precious than gold.
In order to preserve this, a highly intelligent and sophisticated system is needed to maintain the natural balance and thus the habitat of all the species that our earth contains.
Organisms that have been living on the planet for over 800 million years clean and filter these incredible amounts of water every day. Inspired by their unique technology, we at Lehmann-UMT research and develop sustainable solutions, among other things in the field of ultra-sensitive filter technology, thus ensuring that our resources are conserved and that this world is preserved in the form we know it.
