25 microns cut-off filtration cartridge with antifouling capability

The 25 microns cut-off 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 cut-off filtration system with antifouling capability

The same 25 microns cut-off 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 0.1 microns cut-off microfiltration unit with auto back-wash

This microfiltration device with auto-backwash capability is composed by the following components:

• 25 microns filter with antifouling capability;
• 0.1 microns cut-off filtration cartridge;
• PVC IP67 cylinder containing a 12 Vcc peristaltic pump and a three way selection valve, to update the water sample into the 0.1 microns cut-off filtration cartridge and to perform the periodic backwash;
• 250 ml storage bag, to store the filtered sample to be used for filter backwash after the measurement.

Variable depth sampling system with autocleaning 25 microns cut-off 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:

• raw filter inlet and sample line: the incoming water sample is collected with a raw filter having a cut-off of about 1 mm; the 4 mm I.D. sampling Rilsan type tube can be provided up to 50 m length;
• submergible sampling pump unit: peristaltic pump, 250ml/min flow at 12 Vcc; this device can be submerged, max. down to -5 m depth;

• 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.

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.

Water in-situ analyzer

WIZ probe is the state of the art portable “in-situ” probe, to measure automatically up to four chemical compounds in surface and sea water.

The innovative design allows an easy handling and field deployment by a single user.

WIZ probe allows, in the standard configuration, the detection at trace levels of the main four nutrients compounds:

• ammonia (N-NH₃)
• orthophosphate (P-PO₄)
• nitrate + nitrite N-(NO₃+NO₂)
• nitrite (N-NO₂).

WIZ probe automatically manages the well known spectrophotometric wet chemistries and an advanced fluorimetric method for ammonia measurement.

Many other analytical methods are available on request, including silicates, Total P, Total N, iron and other metals.

WIZ Pro is the most advanced analytical probe for field applications:

• the 1.5 ml micro Loop Flow Reactor (μLFR*) enables an extremely low consumption of reagents and calibrants
• the exclusive multibeam compact, optic fibers based, colorimetric detector, coupled with a state of the art fluorimeter
• the new compact cylindrical design allows the deployment as any conventional water quality monitoring probes available in the market
• the new innovative “plug-in” and compact reagents container allows an immediate field reagents and calibration solutions changeover.

* Patented

Results are directly provided in concentration units; all measured values are stored with date, time and sample O.D.; the same data are remotely available through a serial communication port, which allows the complete probe configuration and remote control using the external Windows^® based Wiz Control Panel software.

The Wiz reagents container:

Reagents and calibrants flexible bags are placed inside the “plug-in” compact reagents container.

The bags are connected to the internal analytical reactor with an enhanced version of our exclusive fast hydraulic 10 lines multiconnector*, ensuring quick replacement in the field.

Reagents consumption is limited to about 30-60 microliters of each reagent per single analysis; the reagents container is designed to contain up to 500 ml of reagents and calibrant solution, to ensure at least 1000 automatic field analysis.

Auto-calibration is performed using concentrated standard solutions, contained in the same reagents container.

SYSTEA proposes a series of submergible multiparametric in-situ probes for sequential automatic analysis of up to four nutrients or other chemical parameters in surface and sea water.

Our probes are specifically designed for unattended monitoring in oceanographic research, environmental protection and biological studies; the following models are available:

• NPA Pro
• WIZ probe.

The standard wet chemistries for nutrients analysis used in our in-situ probes are optimized to be used for unattended water quality monitoring in surface and sea water: NH3: fluorimetric OPA method PO4: Molibdate, Ascorbic acid colorimetric method NO3+NO2: UV reduction + NED, SAA colorimetric method NO2: NED, SAA colorimetric method.

Other chemical parameters available are: Silicates Total Phosphorous Total Nitrogen Total Dissolved Iron Sulphide.

Features and benefits

Up to four parameters sequentially measured Easy reagents replacement Low reagents consumption (about 200 microliters of each reagent for analysis) Reagents sealed bags refrigerated by surrounding water.

Advanced functionality Toxic waste is collected in a special bag placed inside the reagents compartment (NPA / DPA Pro) or outside the probe's body (WIZ) DI water is used to wash the hydraulic circuit and to perform a diluted measurement Self-cleaning filtration unit available as option.

Nutrients probe analyzer 

The NPA Pro has been designed to be best integrated in coastal buoys. The two cylinders can be easily placed on the buoy’s body holes and then simply anchored with chains or hooks or snaphooks.It is made of two different PVC cylinders:  the first one includes hydraulic and electronics components; the second one includes reagents, calibrant, DI water and waste bag. A single hydraulic connector with 10 tubing is used to connect the second cylinder to the first one. This multi-connector is provided with a valve to open it during functioning and to close it during transportation, to avoid reagent spillage.

Advanteges and benefits

• Two cylinders are more convenient/easy to deploy: the electronic compartment is never removed;
• The NPA Pro doesn't unbalances the buoy: the single body, if placed externally, can tilt the whole system that needs redistribution of buoyancy;
• If needed, the Cd column, may be placed just above the electronic compartment;
• The reagent compartment may be changed as a whole; its allowance is around 17 litres;
• Long lasting reagents quantity, expected reagent changeover every 45/60 days.
