PurCon Introduction

Retentate Any excess (retentate) is removed via a discharge nozzle.
Since no chemicals are added in the PurCon, any excess can be fed
back into the process.
Permeate The permeate pump transports the permeate to the analyzers via a
hose that is also supplied with the PurCon. It is connected to the per-
meate nozzle.
The quantity to be transported can be varied by a 4-step selection
switch and, thus, optimally adapted to requirements.
Cleaning After 6-9 months of operation, the sample preparation instrument must
be cleaned. Detergent is poured into the filler nozzle for this purpose.
The detergent is disposed of via the outlet nozzle. In sewage treatment
plants, the detergent can be disposed of in the sewage treatment plant.
However, in installations with measuring points for drinking or surface
water, it is imperative that the detergent is disposed of separately.
Inside the housing The actual sample preparation is located inside the housing. The air
supply required for operation is obtained via a compressor. 4 permeate
tracks are operated alternately via a valve. The PurCon is connected to
the analyzer via a permeate nozzle.
Valve settings Two manual valves enable the feed flow to be shut off or the sample
preparation to be emptied.
