Backwash Strainer Sample Pretreatment Unit

This sample pretreatment unit is simple and effective.
Air pushes the sample material out of the sampler to prevent adhesion of contaminants, slime and algae, and acts to back wash the strainer to prevent the strainer from clogging.
In order to obtain a sample, when water is taken in, the sample passes through the strainer and enters the sampler

This unit will reduce trouble with flow blockage, which is the biggest problem for on-line analysis.
The design is suited to measuring samples of suspended particles.
* Stable measurement values are obtained by means of a 2-stage pretreatment process consisting of removing foreign matter with the strainer and pulverizing the suspended particles and making them uniform with the homogenizer.
* Samples are sent via the strainer to the pretreatment section only when obtaining samples. Furthermore, all sample contact components are rinsed with rinse water immediately after samples are obtained. By introducing only as much sample as is necessary and promptly washing, it also reduces slime and algae problems.

This Unit will reduce flow blockage trouble and maintenance frequency, which is the biggest problem for on-line analysis.
The design is suited to measuring samples of suspended particles.
* It has a unique sampling mechanism that does not use solenoid valves.
* By obtaining only the minimum sample quantity necessary, not only are problems with suspended particles reduced, but problems with slime and algae are reduced as well.
* A strainer-equipped homogenizer is included.·All sample contact components are rinsed with rinse water and the strainer is back washed immediately after samples are obtained.
It allows multi-stream measurement. Contamination between streams can be minimized with this pretreatment unit.
* Compressed air and rinse water (tap water) are required.
