FILTRAX Sample conditioning system

Principle of Operation:

The core of the Filtrax ultrafiltration system is the filter membrane. Filter membrane A and filter membrane B, made of special polymer materials, are placed in the same stainless steel container and immersed directly into the water sample. The sample suction and transfer tubes of filter membrane A and filter membrane B are connected to peristaltic pump A and peristaltic pump B in the controller respectively. The two peristaltic pumps of the Filtrax sample preparation system work alternately; during the operation of one peristaltic pump, the sample is filtered through the corresponding filter membrane, drawn up into the controller, and then transferred to the downstream online water quality analyzer. Throughout the entire operation of the Filtrax sample preparation system, the air compressor inside the controller operates continuously, and the compressed air generated is delivered through two air transfer tubes to the vent holes at the bottom of each filter membrane; during the period when one of the peristaltic pumps stops working, suspended particles adhering to the surface of the corresponding filter membrane are removed. This ensures that the Filtrax sample preparation system can operate continuously.

Instrument Features:

• The Filtrax ultrafiltration system uses ultrafiltration technology with high filtration precision; the ultrafiltration membrane can filter particles of 0.15μm;

• The two peristaltic pumps of the Filtrax ultrafiltration system work alternately, drawing samples in turn;

• The unique air cleaning design can automatically clean the built-in filter membrane of the Filtrax sample preparation system, reducing cleaning work;

• The Filtrax ultrafiltration system requires minimal maintenance and needs no submersible pump;

• The sampling tube can be heated, ensuring that the Filtrax ultrafiltration system can still perform sample preparation under harsh outdoor climate and weather conditions;

• The Filtrax sample preparation system can automatically monitor the sample flow rate.
