Primary, Secondary, and Tertiary Sewage Treatment

Tri-Phase Automation is a distributor of Pepperl+Fuchs’ products for waste water treatment facilities. You have at your disposal a wide range of I/O isolators and intrinsically safe barriers for nearly all measurement technology applications, e.g. pressure, differential pressure, temperature, flow, level, positioner, Remote I/O, and much more.


The demands on technical equipment and water quality regulations continue to evolve. In addition, the volume of water treatment has grown.  With these changes and growth, important supplemental measuring points need to be set up, particularly in decentralized parts of the sewage treatment plant. A sewage treatment plant can cover hundreds of acres and include multiple buildings. Greater amounts of data need to be recorded centrally, and the effort involved in commissioning and maintenance has to be reduced to service all field devices and drives centrally from the control room over a fieldbus system in network segments.

Application Solution

The field instruments and control is truly distributed throughout the sewage treatment plant. FOUNDATION fieldbus, PROFIBUS, and in many cases Hart technology have solved the problem of centralized control. It is likely that upgrades and retrofitting of drinking water and waste water treatment plants will include fieldbus solutions.
