Our filtration systems combine modern filter technology, robust materials and intelligent control in a compact yet modularly expandable solution tailored to your requirements.
Whether micro-, ultra- or nanofiltration – we offer efficient filtration technology for a wide range of applications in industry and water treatment.
Our filtration systems impress with their sophisticated filter technology, high-quality materials and modern digitalization. Three strong arguments why our filtration technology solutions set standards both technically and economically.

For applications with lower raw water volumes of up to approx. 2.5 m³/h, we offer compact filtration systems as a plug-and-play solution. The pre-assembled systems are quickly installed, ready for immediate use and ideal for smaller processes or decentralized locations – efficient, reliable and particularly user-friendly.
For higher water volumes or more complex requirements, we develop individually planned filtration systems with a modular design. Each system is tailored precisely to the composition of your raw water and the required throughput – for maximum efficiency and optimum integration into your existing processes.
Compact system or modular design – we will be happy to advise you on the ideal solution for your requirements.
Our compact filtration systems are used wherever process or waste water needs to be treated reliably – even with heavily contaminated media.
Typical areas of application can be found in metal and surface treatment, e.g. to extend the service life of degreasing baths, in mass finishing systems for process water treatment or in cooling water treatment in bypass operation.
Our compact filtration systems offer a practical plug-and-play solution for the flexible treatment of small to medium volumes of wastewater – for example in workshops, production facilities or for the remediation of contaminated sites. They are ideal for applications with limited space and a moderate volume of oily wastewater.
When it comes to larger volume flows, our modular filtration systems come into play. These are individually designed to meet your requirements and wastewater volumes and enable needs-based upscaling – efficient, powerful and easy to integrate into industrial processes.
Our filtration systems work according to the proven crossflow method, in which the raw water is guided across the membrane surface by means of pressure. Ceramic or plastic membranes are installed in a stainless steel module, which reliably separate impurities from the medium.
This produces two streams: permeate, the filtered water, and concentrate, which contains the retained substances. Depending on the application, value can be added from the permeate (e.g. recirculation, post-treatment) or the concentrate (e.g. recovery).
An integrated backwash system considerably extends the cleaning intervals, while chemical cleaning removes secondary deposits on the membrane and significantly increases its service life. The entire process is controlled via a PLC with visualization, including data recording, remote maintenance and GPRS-based monitoring – for maximum process reliability with minimum operating effort.

In industrial water treatment, different filtration processes are used depending on the requirements. Our filtration systems can be flexibly adapted to the respective medium, the desired separation accuracy and the application purpose – from coarse solids separation to the finest molecular separation.
Microfiltration is a mechanical filtration process in which particles, solids and microorganisms are removed from liquids. With a pore size of around 0.1 to 10 micrometers, microfiltration is ideal for the pre-treatment of process water, as a protective stage before ultrafiltration or for the direct separation of suspended solids. Dissolved substances are retained in the water, while unwanted solids are reliably retained.
Ultrafiltration is ideal for separating emulsions, oils, microorganisms and the finest particles down to a pore size of approx. 0.01 micrometers. It enables particularly thorough purification of process and waste water without removing dissolved salts or smaller molecules. Ultrafiltration is used, for example, in degreasing bath treatment, in the separation of oil-water mixtures and for the recovery of valuable components – economically and reliably.
Nanofiltration works with even finer pores (approx. 0.001 micrometres) and is therefore ideal for retaining small organic molecules, hardness constituents and selected salts. It is often used for the treatment of process water, for partial desalination or as an upstream process for reverse osmosis. Nanofiltration combines high retention values with comparatively low energy requirements – perfect for applications with high demands on water purity and resource efficiency.
Would you like to find out more about modern filtration technology, possible applications or technical details? In our FAQs, we answer the most important questions about our filtration systems – comprehensible, practical and to the point.
What is a filtration system?
A filtration system is used to separate solids, oils or dissolved substances from liquids – for example to treat process or waste water in industry and commerce.
What is crossflow filtration?
With crossflow filtration, the medium is guided tangentially to the membrane. As a result, the filter surfaces remain permeable for longer, which enables continuous and efficient filtration.
What is the difference between permeate and concentrate?
Permeate is the filtered water that can be reused or discharged. Concentrate contains the separated residues and is treated or disposed of depending on its composition.
What post-treatment options are there?
Depending on the application, we offer options such as pH or redox value adjustment, reverse osmosis, activated carbon filters or ion exchangers to improve the water quality.
How can the raw water be prepared to relieve the filtration membranes?
By separating light phases (oils, grease, floating matter) and sediments (sludge, sand, metal particles) using separation technology.
How are filtration membranes cleaned?
To prevent scaling or fouling effects, the filtration membranes are rinsed at cyclical intervals with alkaline or acidic membrane cleaners using an automated process, depending on the medium to be treated, in order to maintain the filtration/permeate performance and significantly increase the service life of the membranes.
Is it possible to test the LK system technology in advance?
Suitable compact systems are available for you to test the treatment of your raw water at your premises. If required, we can take your sample in advance on our in-house test system.
How much maintenance is required for a filtration system?
This depends on the medium to be treated and the size of the system. We support you by drawing up an operating and maintenance plan and, if you wish, we can also take over the maintenance and operation of your system.
