Sample filtration for in-situ probes
25 microns filtration cartridge with antifouling capability
 |
The 25 microns inlet cylindrical filter cartridge (dimensions 30 mm x 100 mm) avoids the clogging of the sample inlet and protect the probe’s inlet tube and internal hydraulics from fouling. It has to be mounted directly on the sample line and it has to be cleaned regularly at the time of maintenance service. |
Autocleaning 25 microns filtration system with antifouling capability
 |
The same 25 microns inlet cylindrical filter cartridge is provided coupled with a compressed air generator and sample line rinsing pump: this device produces compressed air at 1 bar to clean automatically the filter; a secondary peristaltic pump updates the outlet of the filter to the inlet of the probe. This device has to be mounted outside water; the internal air compressor is protected by a water level sensor placed at the bottom of the device. The autocleaning and rinsing sequence is defined by a programmable internal timer. |
In-situ self-priming 0.2 microns microfiltration unit with auto back-wash
 |
The microfiltration device with auto-backwash capability is composed by the following components:

Variable depth sampling system with autocleaning 25 microns filtration system and antifouling capability
 |
The WIZ variable depth sampling system can be used to allow the measurement of a water sample collected at various depths in a lake, lagoon or estuary, down to -50 m depth. The system is composed by the following units:
|
- filtration chamber: it contains the 25 µm cut-off filter with autocleaning and biofouling protection: this unit can be opened from the bottom side to ensure a complete manual cleaning of the filter during routine maintenance activities; the internal volume of the filtration chamber is about 250 ml; this device can be submerged too;
- compressed air generator and sample line rinsing pump: this device produces compressed air at 1 bar to clean automatically the filter; a secondary peristaltic pump updates the outlet of the filter to the inlet of the probe. This device has to be mounted outside water; the internal air compressor is protected by a water level sensor placed at the bottom of the device. The autocleaning and rinsing sequence is defined by a programmable internal timer.
