know-how in different applications for the environmental industry.”
The applications specialists
CUT Membrane Technology has gained a huge amount of expertise in the use and manufacture of membranes and filtration modules during more than a decade. This enables us to support our customers with process and application knowledge in sectors such as chemistry, food and environmental technology especially in the treatment of wastewater and process water.
We deliver customized membrane and module solutions to almost all countries around the globe.
Treating landfill leachate
The treatment of landfill leachate is one of the most challenging filtration tasks in membrane technology. In principle landfill leachate consists of rainwater that drains through landfill sites, whereby a large variety of chemical compounds are dissolved in the water and all types of particles are washed out into the water as well.
The objective of the process technology is to collect the permeate (filtered water) that is produced during leachate water treatment so that it can be fed into a clarification plant without any further treatment or even be recovered for internal reuse.
The combination of biological pre-treatment of leachate in a so-called bio-reactor and the subsequent ultrafiltration (UF) has proven itself using our T-CUT UF module portfolio as the heart of the processing chain.

Clarifying industrial wastewater
Today, biological wastewater treatment plants are experiencing a steady growth with regard to the correct and professional clarification of industrial wastewater. The widely used ultrafiltration membrane filtration process is very similar to the method used for the municipal treatment of landfill leachate.
The treatment plants generally address the reduction of particles, oils, COD and BOD for the purpose of ultimately discharging the water into rivers or lakes.
The biologically supported wastewater treatment is optimized by the subsequent use of CUT ultrafiltration membrane modules for concentrating and / or retaining the biomass.
Reduction of operating costs in an existing plant
Using an example, we will show you how to reduce operating costs in an existing plant. This is a reference project for a membrane bioreactor in a sewage treatment plant operated by Thor in Speyer, Germany.
Recycling abrasive water
In order to be able to economically and ecologically optimize the industrial machining processes used for glass and ceramic materials, reuse or treatment of the abrasive water that is produced represents an important aspect with regard to reducing the manufacturing or disposal costs.
For example, the very finely dispersed particle abrasions as well as the ingredients dissolved in the cooling liquid often have to be filtered out in accordance with the requirements and the required limit values to ensure successful process water recycling. In this case the effect of the cleaning additives that are used should not be significantly changed by the filtration process.
Microfiltration using our range of T-CUT PP modules reliably separates particulate impurities while the modules are extremely acid-stable and abrasion-resistant.
Pickling acid used in a rolling mill
Huge quantities of spent pickling acids are produced when cleaning processes are run in steel rolling mills and disposing it of it after use is both time-consuming and cost-intensive.
In particular, the high costs are incurred from neutralizing the acids and conditioning them accordingly so that they can be fed into a clarification plant as well as from the correct disposal of the sludge produced during the processing.
The sheet metal acid treatment is combined with mechanical cleaning methods (e.g. brushes) for an optimum result, whereby a particularly polluted acid mixture is produced as a “waste product”.
This is an application for our range of T-CUT PP modules that ensures permanent and reliable microfiltration with extreme stability with regard to acids, bases and particle abrasion.
