Compact, high-performance and reliable filtration solution for medium contamination levels

The compact, powerful and low-maintenance CMS-P filtration system is ideally suited for sampling liquids with a medium level of contamination in municipal and industrial applications, such as surface water.

The system reliably delivers permeate and can be flexibly adapted to permeate rates of 5 to 15 L/h as well as varying wastewater conditions, thanks to a wide range of available filter grades and probe options. The submerged filter units or membrane probe operate in combination with a pump, while a programmable compressed air backflush cleans the membranes or metal mesh, prevents clogging and ensures consistently high filtration quality. For outdoor use, both the system/control cabinet and the filtrate lines can be optionally heated.

The robust mounting bracket made of stainless steel and aluminum allows for quick installation on railings or tank edges. A practical quick-release mechanism simplifies maintenance and enables fast replacement of membrane or filter probes, making the CMS-P system a fully coordinated and particularly user-friendly solution.

CMS-P System – Summary

The CMS-P system from ETL Verfahrenstechnik GmbH sets new standards in sample filtration and provides a reliable solution for supplying permeate to analyzers in wastewater treatment plants. It is specifically designed for applications with medium contamination levels and performs particularly well in effluent and surface water applications.

Its compact design and low weight ensure flexible and user-friendly operation. A wide selection of membranes with different materials and cut-off sizes allows maximum adaptability to varying process conditions. A programmable automatic compressed air backflush keeps membrane probes and filter units clean, ensuring consistently high filtration performance and permeate flow rates of up to 20 L/h. The integrated quick-release mechanism enables easy maintenance and fast replacement of probes.

With its robust membrane filtration and compact construction, the CMS-P system offers a durable and reliable solution for sample filtration in wastewater treatment plants. An optional heated version is available for outdoor use, ensuring reliable operation even under harsh weather conditions and making it ideal for SBR applications. The CMS-P system is a simple and dependable filtration solution for demanding environments.
