EZ-Size™ AD

Self-cleaning Filtration System for Digestate Samples

The EZ-Size™ AD is a filtration system developed to make solid-free samples from the liquid fraction of anaerobic digesters available for on-line analysis.  Devoid of complex engineering and equipped with oversized ball valves for sample intake and drain, this filtration system can cope with the difficult properties of anaerobic effluent samples and support optimal up-time and analytical performance of the connected analyzer.

Available pore sizes:
200 µm, 500 µm

Reduced maintenance
All AppliTek filtration and preconditioning systems are designed for fully automatic operation and require virtually no human intervention. Basically all systems are incorporated with a blow-back action by instrument air. This fundamental design principle does not merely allow trouble-free sampling, moreover it contributes to high up-times. The design and choice of materials of our systems is second to none and make them ideal to be used in many applications, even for non-AppliTek analyzers.

The EZ-Size™ AD is also known as the Hach EZ9130 and available worldwide through your local Hach team.
