Gröger & Obst GO-6A stripper

The GO-6A (automatic outgassing and setting twice over) prepares very heavily contaminated sample water continuously.

For heavily contaminated sample water, our previous solution was the rugged, easy-to-clean tube stripper.

A consistent advancement for reducing maintenance effort is our GO-6A stripper with automatic outgassing and setting – twice over.

In the past, unwanted particles such as sand orsimilar materials entered the reactor along with the sample water via the peristaltic pump. This led to contamination in the tubing system, increased wear on the feed tube to the reactor and of course un-necessary contamination of the reactor.

With the GO-6A stripper, this can largely be prevented. Right at the beginning, unwanted, heavy particles can settle in a special container under increased ambient pressure.

These particles are removedautomatically by means of a robust pinch valve.Time-consuming cleaning work on the valve is therefore no longer necessary.

This first measure prevents unwanted particles from settling in the downstream tube stripper and causing carryover of measured values.

After the inorganic carbon has been stripped out, the sample water flows into a settling tube in which remaining unwanted particles can settle once again. At the same time, the sample is taken to the reactor. At regular intervals, the pinch valve at the lower end of the settling tube opens and the accumulated particles are removed.

By choosing settling and flushing times individually, the system can be optimally adapted to the ambient conditions.
