Efficient Solid-Liquid Separation
The targeted removal of solids from process and wastewater is an important part of industrial water treatment. As a reliable preliminary step, filtration removes disruptive particles before the water undergoes further processing steps or is discharged. It thus lays the foundation for compliance with specified limits and protects downstream equipment.
Rising costs and stricter environmental regulations place high demands on industrial wastewater treatment. Our filtration processes are designed to separate solids and particles. They help ensure compliance with required discharge limits and serve as a critical treatment step prior to discharge or to protect downstream treatment systems. By specifically reducing pollutant loads, wastewater fees can also be lowered. Depending on process requirements, filtration is also suitable for treating partial streams for subsequent recycling.
Filtration protects downstream systems by specifically trapping suspended solids, particles, and particulate organic matter. This helps reduce deposits and blockages, which can extend maintenance intervals and help prolong the service life of your equipment.
Industrial wastewater treatment allows you to reduce your fresh water consumption and, at the same time, lower your wastewater fees. When treated water is recycled back into the process, wastewater streams can be used as a resource, thereby reducing disposal costs.
Strict environmental regulations place high demands on wastewater discharge. Our filtration processes physically separate critical solids from the water stream before the water leaves the facility. This helps ensure compliance with applicable limits and helps prevent limit exceedances and the resulting operational consequences.
Every type of industrial wastewater has a unique composition. Whether dealing with particulates or organic contaminants, our filtration processes are designed for situations where targeted separation is required. We develop the right solution to meet the specific requirements of your industry and your process.
Using state-of-the-art industrial water treatment technology, we treat contaminated water for further use or discharge. The tailored combination of processes ensures compliance with applicable requirements and enables the efficiency of the water reuse.
Sand, glass, or multimedia filters form a mechanical barrier against plastic particles, sand, and abrasives. As part of a treatment process that typically consists of multiple stages, they are used in particular where upstream process steps—such as precipitation, coagulation, or clarification—have already prepared the substances for filtration.
The interaction of the process steps protects downstream components, such as membrane systems or ion exchangers, from plastic contamination and can extend their service life.
Dissolved iron and manganese can cause deposits and brown discoloration during operation. While iron oxidizes relatively easily, manganese is chemically much less reactive. That is why we rely on targeted pre-oxidation through aeration in combination with a microbiologically activated dolomite filter material. This acts as a biological catalyst and converts even manganese—which is difficult to remove—into filterable particles that are subsequently separated out.
As a preliminary step, this process can also be combined with downstream modules—for example, with a water softening system if the process water also needs to be treated to remove lime.
Non-emulsified oils and greases, as well as floating layers, can be separated from the water stream using mechanical separators or coalescing filters. By combining these separators with dissolved air flotation (DAF) systems or downstream adsorption stages, we protect sensitive processes from oil and grease contamination and increase the plant’s operational reliability.
Filtration specifically removes the particulate fraction of organic contaminants. For more thorough treatment, we combine mechanical separation with biological treatment. This allows us to reduce both dissolved and suspended organic contaminants and helps ensure compliance with discharge limits.
Complex organic molecules, such as pesticides and herbicides, can be largely removed using specialized activated carbon filters. In combination with UV irradiation or advanced oxidation processes, even persistent environmental toxins can be treated, and their residues in water can be reduced.
Pharmaceutical residues can be removed from water through adsorption onto activated carbon. We typically integrate this filtration as a final treatment step following a biological treatment stage. This prevents critical trace substances from entering the public sewer system in an uncontrolled manner.
After chemical precipitation, heavy metals can be mechanically removed from the water using filter media or chamber filter presses. We coordinate the chemical conditioning and subsequent filtration to reduce the pollutant load and comply with applicable legal requirements.
Our industrial water filtration systems use various filtration processes to reliably remove solids and suspended solids from the water. Using modern and robust machinery, we tailor these processes to the requirements of different industrial sectors. The goal is the efficient treatment of your process water and wastewater—even with varying levels of contaminant load.
This customized filtration ensures consistently high-quality particle removal and protects downstream systems as well as the final discharge from unwanted solids contamination.
Before the water reaches the actual filter, dissolved or finely dispersed substances are converted into a filterable form as needed. For example, by adding flocculants, even the smallest particles combine to form larger units. This allows substances to be retained that would otherwise be too small for the filter medium used.
The pretreated water flows through the filter medium, which is selected to handle the specific particle load. Depending on the process—for example, deep filtration in a sand bed or surface filtration using special cloths—solids, flocs, and fine particles are retained. The purified water passes through the filter medium, while solids and unwanted turbidity are separated out.
To ensure that the system remains efficient over the long term, the filter medium is automatically cleaned depending on the system type. Sand and gravel filters are periodically backwashed in a countercurrent flow. Cartridge and cloth filter systems, on the other hand, use pulse or continuous cleaning methods. During this process, the trapped contaminants are dislodged and systematically removed. The system is then ready for the next filtration cycle.
Every industrial process has different water quality requirements. We’ll work with you to find the right solution for your Wastewater treatment.
The Foundation for Safe Industrial Processes
Our filtration processes provide an important barrier against harmful particles and deposits. Their strengths are particularly evident when using well water: Through an integrated pre-oxidation process, dissolved iron is converted into filterable particles, which are then removed. This supports stable system operation and reduces dependence on expensive municipal water.
Ensure Precise Conductivity
High-quality process water ensures your product quality and protects your infrastructure. Our filtration processes are a crucial first step in this process: They remove particles and turbidity to protect downstream systems such as water softeners, Reverse osmosis (RO), or EDI mixed-bed systems. This coordinated process chain lays the foundation for the water purity required by your industrial processes.
Optimize Operating Costs
Not every application requires drinking-water quality. The water treated through our filtration processes provides a suitable basis for cooling processes, fire suppression systems, or washing applications. By recycling the water, you can optimize your water balance and reduce operating costs. At the same time, you are helping to meet the environmental requirements of modern industrial sites.
Circular Economy
Close the water cycle directly at the source. Using appropriate filtration methods, we treat your wastewater so that it can be reused in the process. This reduces wastewater fees and decreases your facility’s dependence on local water resources—a solution that is both environmentally sound and highly efficient.

Every industry has its own specific water treatment requirements—such as fluctuating contaminant loads, strict discharge limits, or sensitive production processes. We combine our process engineering modules to precisely meet the needs of your industry. Discover our customized filtration solutions for a variety of industries and applications.
Stable Processes Despite Oil and Metal Abrasion
Cooling lubricants, oils, and metal particulates can contaminate your water systems. Our filtration processes reliably remove these substances and protect downstream process stages from scaling. The result is treated water that is suitable for reuse in cooling and production systems.
Targeted Removal of Organic Contaminants
High levels of sugar, grease, and proteins place special demands on the process chain. Our filtration processes remove organic substances and solid particles, preparing the water for further treatment. This prepares the water for recirculation and helps ensure compliance with discharge regulations in food production.
Reliably Retain Pigments and Resin Particles
Pigments, resins, and solid residues require high-performance treatment. These substances are removed using appropriate filtration methods to protect subsequent process stages from clogging. In combination with adsorptive treatment stages, the water is thus treated for further production steps or prepared for discharge.
Process Reliability for Complex Residues
Complex chemical compounds and particulate matter pose significant challenges for wastewater treatment. Our filtration processes reliably remove undissolved substances and protect downstream separation processes from fouling and failures. In combination with adsorptive treatment stages, you receive treated water for further production steps while simultaneously reducing disposal costs.
Recovering Fibers and Solids
Fibers, starch, and fine suspended solids often result in high levels of wastewater contamination in paper production. Our filtration processes enable the targeted separation of these residues. This prevents blockages in the screen sections and increases plant uptime. In combination with additional treatment stages, we support the recirculation of water back into the production process and help improve your water balance.
Custom Solutions for Your Industry
Every production process generates its own wastewater challenges. Our filtration processes can be tailored to your specific parameters to reduce particulate loads and efficiently reuse water. By combining different types of systems, we develop a solution tailored to your industry’s requirements.

Yes, most systems have a modular design. They can be integrated into existing infrastructures to save space, for example to reduce the load on existing biological stages or to extend the service life of membrane systems.
Our modern filtration processes react flexibly. Upstream conditioning stages or the combination of several filter lines allow peak loads to be buffered without jeopardizing the quality of the filtrate.
Our systems are designed for maximum automation. Through sensor-controlled cleaning cycles, the respective filter medium cleans itself automatically as soon as a defined differential pressure is reached. This minimizes the need for manual intervention, prevents Blockages, and ensures consistently high flow rates during continuous operation.
Due to their design, individual filters can usually only handle a specific range of particles. For optimal results, we combine various processes into an intelligent chain: While robust coarse filtration in the first step captures the large solids, downstream fine filtration ensures that even the smallest suspended solids are completely removed. Only through this combination can we achieve consistently high water quality and reliably protect your system.
