Wastewater treatment in surface technology
Pre-treatment, rinsing or cleaning in surface technology generates large quantities of contaminated wastewater. Standard processes quickly reach their technical limits during treatment. What remains are large quantities of wastewater with high costs. We develop evaporator systems that are precisely tailored to your waste water and thus recover up to 99 % of the water for your production.
With these processes
our customers take a close look:
- Chemical pre-treatment, e.g. cleaning, degreasing, pickling, phosphating
- Mechanical pre-treatment, e.g. grinding, polishing
- Surface coating, e.g. painting, powder coating
This results in these typical waste water flows:
- Cooling lubricant rinsing water
- Iron phosphating rinsing water
- Zinc phosphating rinsing water
- Pickling rinsing water
- Mass finishing rinsing water
- Electroplating rinsing water
- Hardening shop rinsing waters
Our goal: maximum water recovery.
This is how we plan your treatment system:
To treat complex wastewater streams so that they can be reused, we at KMU LOFT Cleanwater work according to our own solution principle.
Starting point: Your wastewater
First, we analyze the composition of your wastewater streams. To do this, we draw on your information and our extensive experience from the systems we have implemented. Depending on the complexity and requirements, we take samples and analyze them in our in-house laboratory. If no wastewater is available, we draw on our database with thousands of analyzed waters depending on the production processes and industries.
Definition of process chains
We then define the process chain from the inflow of dirty water to the finished distillate and concentrate. Most KMU LOFT Cleanwater systems have several stages of pre- and post-treatment in addition to storage in tanks. The aim is an efficient and safe process. The distillate should be able to be reused or discharged. The concentrate should contain as little residual water as possible and be easy to recycle.
Implementation in plants and systems
Once the process chain has been established, implementation begins by selecting the right vacuum evaporator and the best systems for pre- and post-processing as well as intermediate storage. The result is an individual offer based on standardized system elements.

Sustainability up, disposal costs down
With KMU LOFT Cleanwater's evaporator technology, you can achieve a closed cycle for your wastewater streams. The resulting distillate is so pure that you can easily reuse it in all pre-treatment processes. At the same time, your disposal volume is reduced to a minimum. In addition to the fresh water and disposal costs, your energy costs are also drastically reduced, as our vacuum evaporators only consume an average of around 25-80 kWh per m³ of wastewater fed in.

Our answer to (almost) any waste water: the vacuum evaporator
They work almost by themselves, require little space and recover pure distillate even from heavily contaminated wastewater. Our vacuum evaporators with natural or forced circulation have been reliably and safely processing all types of wastewater for decades. MVR evaporation has been proven to be the "best available technology" for numerous industrial applications.
INDUSTRY REFERENCE
Römer surface technology
Efficient wastewater management for 30% more throughput in the coating line.
Römer Oberflächentechnik GmbH is now saving even more with the optimized wastewater treatment from KMU LOFT Cleanwater: 98 % of the process water flows back into production, process times and energy consumption are reduced by 50 % and throughput increases by 30 %. Sustainable, economical and environmentally friendly - this is how modern surface technology works.
Service for a long system life
Our vacuum evaporators run reliably and trouble-free for years. Many customers only get in touch when something needs to be replaced. However, it pays to look earlier: A regular check of the system parameters in conjunction with the current wastewater flows helps to significantly extend the service life of your system. We can also detect numerous faults and make adjustments via remote maintenance without restricting system availability.
