With the innovative SPALECK process water treatment system, compound-water mixtures can be efficiently circulated in a closed circuit. Up to 97 % of the used water can be saved – and up to 95 % of the compound remains in the process. This not only saves valuable resources, but also significantly reduces your operating costs. Recirculation improves process reliability, reduces maintenance costs and fulfils the highest requirements for sustainability and cost-effectiveness.
When treating process water, we differentiate between four types of treatment:
During sedimentation, the process water is conducted into a cascade tank where it is sedimented. Abrasions from workpieces and abrasive media settle to the bottom. The cleaned water from the last cascade is fed back into the surface finishing system. The sediment residues are removed manually. This process is particularly low-maintenance and cost-efficient.
Throughput up to 200 l/h
Centrifugation is a purely mechanical separation process in which solids are pressed against the outer wall of the centrifuge by centrifugal forces. The clarified water is then fed back into the clean water tank or directly into the process. This method is particularly efficient, low-energy and easy to maintain.
Throughput 400-2,000 l/h per system
Precipitation and flocculation is a proven chemical-physical process for removing the finest impurities in process water. Through the targeted addition of flocculants, dissolved heavy metals, emulsions and fine solids can be reliably bound. The clarified water can then – depending on the legal requirements – be discharged into the sewage system.* The resulting sludge is dewatered using a chamber filter press and disposed of professionally.
* The disposal of processing liquids into the sewerage system is subject to approval and the legally prescribed values.
Vacuum distillation is particularly suitable for process water with a low solids proportion and is preferably used in demanding applications – e.g. when polishing precious metals or sensitive precision parts. The water is vaporised under vacuum and recovered as a fully demineralised distillate. This can be fed directly back into the process – resource-saving, efficient and environmentally friendly.
Throughput 20-2,000 l/h
Recycling centrifuge ZM4
The semi-automatic centrifuge ZM4 is ideal for small to medium-sized surface finishing systems. Its compact design enables space-saving integration into existing plant environments. Thanks to its wide range of applications, the ZM4 is one of the most widely used centrifuges in the field of process water treatment. It impresses with its reliability, simple operation and solid separation performance at low operating costs.
Recycling centrifuge ZMT4F
The ZMT4F is a semi-automatic recycling centrifuge with an integrated fresh water tank for buffering. This allows it to supply several surface finishing systems simultaneously and ensure particularly high process stability. For even better cleaning results, the system can be extended with a flocculation unit to efficiently remove the finest particles from the water. Ideal for demanding applications with high quality requirements.
Recycling centrifuge ZA3
Our fully automatic ZA3 centrifuge can be precisely customised to individual requirements thanks to its modular system. It can be combined with additional components such as process and clean water tanks, agitators or flocculation equipment. An integrated peeling blade reliably removes the settled solids from the rotating centrifuge basket and automatically transports them to a mobile sludge trolley. The ZA3 stands for maximum automation, efficiency and reliable water treatment.
Waste water treatment plant GAB
The GAB is a robust and versatile plant for treating a wide range of process liquids. The aim is to ensure safe discharge into the sewage system in accordance with legal requirements. Targeted precipitation and flocculation removes heavy metals, emulsified oils and suspended solids. The result is largely clarified wastewater, while the resulting sludge is disposed of using separate processes.
Vacuum evaporator VD
Our VD vacuum evaporators are specially designed for the treatment of process water with a low solids content. The process is particularly suitable for sensitive and high-quality machining processes – such as the polishing of precious metals. Evaporation of the liquid produces a fully demineralised distillate, which is fed back into the production process as pure water. The system is highly efficient and particularly environmentally friendly.

Inspection technology for maximum precision
The material handling is realized by our in-house machine construction in coordination with the requirements of the inspection technology.
Our proprietary software solution makes it possible to solve the inspection task in a customer-specific manner and includes the option of defect classification and statistical evaluation.
EMS sensors
This measuring principle for checking the electromagnetic signature is used worldwide in vending machines in which coins are used for payment. Inductive testing of the coin or coin blank provides information about the material composition and/or coating of the coin/blank. The measured values of the individual object are compared with a material database and assessed as good or bad depending on the deviation from the references or the deviation defined as acceptable.
Eddy current measurement
Eddy current measurement is a non-destructive method for testing metallic surfaces. With the help of high-frequency electromagnetic interactions, different material hardnesses can be detected and analyzed both manually and automatically. This method plays a decisive role in quality assurance, as it measures the mechanical resistance of a material against the penetration of another body.
2D camera technology for edge inspection
For geometric reasons, 2D and 3D camera technology only captures the top and bottom of an object, but not the edges. A special 2D camera in combination with a ring light and a catadioptric lens is used to inspect the edge surfaces.
The following features can be checked using 2D camera technology for edge inspection:
3D camera technology
3D image capture picks up where 2D camera technology reaches its limits, particularly with regard to the depth of field of the images and the ability to recognize differences in height. To create a height profile, the component is illuminated with a line laser. The laser beam is reflected and captured by a camera. The illumination of the line laser generates many sectional images. This partial information of the component is put together by the software to form an overall object.
The following features can be checked using 3D camera technology:
2D camera technology
2D image capture is based on the principle of the human eye – light falls on an object, is reflected and captured by the eye. In our systems, artificial lighting is used to generate light beams that are reflected by the object and captured by the camera. The choice of suitable lighting and camera depends on the application.
The following features can be checked using 2D camera technology:
Decision
The components are classified based on the set inspection parameters. The data can be stored and analyzed via an SQL database or transmitted to a higher-level system.
Image analysis
The image analysis is performed by algorithms that process the data generated by the image acquisition. These algorithms are integrated into the operating software, which is used to control the system and define and save the inspection criteria.
Image acquisition
Image acquisition includes the selection of lighting and camera technology. The type and sensitivity of the components are determined according to the previously defined test characteristics and tolerances.
Handling
The variety of components and the desired degree of automation make component handling crucial. Transport and precise positioning under the inspection tool are crucial for optimum inspection results.
Inspection
The same requirements apply for an optical inspection as for the human eye. It is important to describe the component, define the characteristics to be tested and specify the tolerances.
