Universal self-cleaning filtration for digestate samples - compatible with the EZ7200 Series
About the EZ9100 Series

The successful implementation of online analyzers in process control strategies could not have been achieved without the development of a new generation of automatic sampling and sample preconditioning systems. The EZ9100 Series are the result of many years of field experience in combining analyzers with filtration units.

Simplified operation by self-cleaning action
All preconditioning systems are designed for fully automatic operation and require virtually no human intervention. Basically all systems are incorporated either with a blow-back action by instrument air, or a specific cleaning cycle. This fundamental design principle does not merely allow trouble-free sampling, moreover it contributes to high up-times.

The EZ9130 is a filtration system developed specifically for sampling wet type anaerobic digesters to make solid-free samples available for online analysis. Devoid of overly complex engineering, the filtration can handle the difficult properties of sludge and wastewaters charged with high levels of insoluble constituents:
- Self-cleaning sample filtration with various pore sizes
- Large-bore pneumatic ball valves for sample and drain
- Automatic cleaning by solenoid controlled instrument air
- PLC or analyzer controlled cleaning frequency
