Waterworks – Pressure filter system
The heart of water treatment
The quality of untreated water can vary widely in nature, depending on the extraction point. Therefore around one third of the entire amount of ground filtrate in the waterworks is conducted through a total of nine pressure filter tanks filled with quartz chips for the biological filtering out of manganese.
This is where the core process of water treatment takes place. Because, in addition to flocculation, this is where the decision is made as to which suspended particles and colloids are filtered out of the untreated water and in what amounts. And this answers the question as to what quality and composition of water can ultimately be provided to the consumer.
Gelsenwasser AG and other well-known waterworks have decided to use OPTIFLUX in this key area of water treatment. In many regards, the EMF specialist for water is predestined for this task: firstly, the device stands out due to its very high measuring performance while also boasting extremely rugged construction. The steel containment is fully welded and leak-tested at the factory.
Secondly, each OPTIFLUX is thoroughly tested over a time period of 20 hours at temperatures between –20 and +60 °C. These tests ensure a quality standard, which we call "KROHNE proved". These tests far exceed the legal requirements and therefore provide our customers with a high degree of investment security.
With so many outstanding properties, it is no wonder that the decision to use OPTIFLUX came easily to so many waterworks.
