Environmental Engineering

Our innovative systems are unique worldwide and are used in many countries to rehabilitate rivers, canals and lakes.

During the last 100 years many waterways have been polluted and filled up by mud and sludge caused by industrialization and civilization. Unfiltered wastewater from factories, the mining industry and households have been dumped into waterways over the years. Waterways have become highly contaminated and poisoned. The economical and ecological damages run into billions of US dollars every year (flooding damage, water contamination). Conventional and outdated methods of extraction are expensive and not effective.

uwt.swiss offers innovative and globally unique solution to clean and protect the waterways. We are a Switzerland based industrial innovation company and our portfolio of products compromise of mobile desludging systems for the restoration of waterways and for industrial sludge treatment.

We offer ‚best in class‘ separation, sludge treatment and dewatering machines in one integrated and fully digital system.
We deliver Environmental Engineering.

More than 30% of global methane emissions originate from inland water bodies such as rivers, lakes, and ponds, covering about 3 to 4% of the Earth's land surface. These emissions are primarily caused by sediments in these water bodies.

Our main focus lies in the revitalization of urban waterways through the removal of sediments, the recycling of separated materials, and subsequently, the implementation of long-term self-cleaning systems. These self-cleaning systems include oxygen supply as well as aquatic and terrestrial phytoremediation. For over 10 years, we have been conducting such sediment removal projects with our own equipment in Europe and Asia.

Large-scale projects of this nature are costly for Municipal administrations. Our new innovative approach aims to calculate the greenhouse gas emission (GHG emission) potentials of these urban water bodies to generate carbon credits. By monetizing these carbon credits and through the recycling and sale of separated and dewatered sediments, the costs of revitalizing urban waterways could be massively reduced. These incentives for Municipal administrations represent a turning point in the revitalization of urban water bodies.

The innovative uwt.swiss mobile Desludging System is ideally suited for cleaning and desludging canals and waterways in densely populated urban areas.
The system can also be used in treating industrial sludge, e.g. mining and steel industries, preventing the waterways from being polluted.

The uwt.swiss system consists of a Separation Unit, a Sedimentation Unit, a Dewatering Unit and a Control & Polymer Unit incorporated in four 20’ standard sized shipping containers.

The system separates and dewaters:

  • Trash and coarse material
  • Sand, ready to use in construction industry
  • Sludge, 75% dry, ready to use for landfill
This mobile and fully automated system is globally unique:
  • Our Automated Intelligence Control System, AICS is configured for the optimal operational settings, so electricity and polymer use is minimal
  • Quick installation and minimal space required.
  • Very high throughput (150m³/h).
  • Sensors monitor that only clear water will be returned to the waterways
  • Operating costs are much lower compared to conventional technologies such as digging with excavator
  • Just one person is required to operate the system
  • Greatly reduced transportation cost due to high dry substance (75% DS) of the output

uwt.swiss and Global Partner Network

Together with our global partners, we offer ‘best in class’ Sludge Treatment and Dewatering machines in one fully integrated system.

Sophisticated mobile solution ideally suited to urban areas
Four integrated 20’ containers, relatively easily located to where it is required, and with a footprint of just 150m², and using pipes that can be extended. Our own proprietary Control System is used to monitor all events, with optimal settings for flow rates, process water and polymer usage, and with minimal operator input.
