Wastewater treatment that pays off

Industrial water treatment has an image problem in many companies: it is often seen as a necessary evil and a pure cost factor. But this image is changing dramatically. What if your wastewater was no longer a waste product, but a valuable source of energy?

From cost factor to efficiency driver

At SPALECK Wassertechnik, we don’t see wastewater as a problem, but as a resource. The key to this transformation is anaerobic water treatment. For us, it is one of the most important levers for real industrial sustainability. The process offers three decisive advantages for modern companies:

  • Biogas production: Organic loads in wastewater are not simply destroyed, but converted into valuable energy.
  • Minimal CO2 footprint: Compared to conventional processes, the system’s own energy requirement is minimal.
  • Holistic efficiency: The cycle is closed – from the first cleaning stage to the finished biogas treatment.

Why standard solutions fall short here

In theory, generating energy from wastewater sounds simple, but in practice it is complex. We know that No two wastewaters are the same. The chemical composition, temperature and pollution load vary massively depending on the industry and operation. Anyone who relies on “off-the-shelf solutions” is wasting potential or risking unstable processes. That’s why we develop each system as a unique technical solution.

Individual planning instead of rigid concepts

A solution is only good if it integrates seamlessly into your daily routine. We plan our systems precisely according to your process parameters:

  • What does the system have to do?
  • How much space is available?

Our credo: the technology must adapt to your business – not the other way around. This results in highly efficient systems that perfectly combine ecological responsibility and economic success.

Frequently asked questions

AutoCLEAN was developed in the SPALECK TestCenter and with and for real recycling applications. The system has been tried and tested in practice and shows optimum results in real recycling plants. We will be happy to provide you with specific references and results for specific materials and applications on request.

The easiest way is to test your original material in the SPALECK TestCenter. Alternatively, we offer you the option of inspecting reference systems. In both cases, you can see how AutoCLEAN behaves with your material and what positive effects AutoCLEAN has on the treatment process.

AutoCLEAN aims to reduce operating costs in the Recycling process – in particular through less cleaning effort, optimized production and treatment processes and optimal use of screening technology. In many applications, this results in rapid economic benefits.
