Real-Time Wastewater Sampling Device

I was immediately convinced by the durability of the components and the simplicity in maintaining the system.


The cost-effective method of filtrate sampling

The OSF real-time wastewater sampling device provides a low-cost and effective method of supplying filtrate for all online measuring devices on sewage treatment plants.

Simple in construction – effective in function

The uncomplicated yet efficient design of the OSF sampling device facilitates a reliable and cost-effective way to supply measuring instruments with filtrate. The filtrate required for online measuring devices can be obtained directly by the OSF device via the sample probe. The special separation filter makes it possible to separate and pump only very small filtrate matter instead of sludge. For this purpose, the separator is immersed from its mount on the on the brim of the tank into the medium that is to be measured. The filtrate, which is free of solids, is then transported to the measuring device with a magnetic dosing pump.
