About us

A German company for existing plants.

LIT International GmbH, based in Düsseldorf, specialises in innovative integrated solutions based on nanotechnology for wastewater treatment, the modernisation of sewer systems, and the stabilisation of biological processes at treatment plants.

Efficiency from what already exists.

Our core activity is improving the efficiency of existing wastewater treatment facilities without capital construction, through modern technological solutions and specialised reagents.

We cooperate with a number of leading European manufacturers that develop innovative technological products and reagents based on modern scientific research. Our task is to adapt and implement these proven European solutions, taking into account the specific characteristics of each facility and the requirements of local regulations. When necessary, we involve specialists from leading European universities and scientific centres, both to develop customised solutions and to provide expert evaluation of complex treatment processes.
