Bringing the benefits of IoT to the wastewater industry

Over the last 30 years, the Internet has revolutionized the way humans interact. The next step in the evolution of digital communication is the interconnection of machines, sensors and various digital systems. This is commonly referred to as the Internet of Things (IoT) and brings completely new possibilities to increase efficiency and add value to customers.


Alfa Laval is taking an active part in this development. With our IoT services for wastewater plants, our customers get new possibilities to cut service and polymer costs, increase reliability and increase overall efficiency. We are investing heavily in R&D and we will continue to release new IoT services as technology progresses.

Remote Monitoring


Alfa Laval Remote Monitoring gives you the fastest and best support from Alfa Laval. It enables our service experts to provide you with valuable advice on maintenance, service planning, process optimization and troubleshooting. Your wastewater decanter centrifuge is connected to Alfa Laval’s monitoring system via internet, allowing our staff to access its data remotely and support you in the best way.


Fast and accurate help

With Remote Monitoring, our service engineers can monitor your decanter centrifuges' operating parameters remotely when you call them for support. This minimizes time for diagnosing problems and sending spare parts in case your decanter needs servicing or repairing.


Remote access

Remote Support Monitoring also gives you remote access to your decanter centrifuges through Alfa Laval’s service web. Technical data can be analyzed through a web interface, making it easy to benchmark different decanters and optimize operation. There is also an option to send alarms via SMS or email.


Remote Control


If your equipment is based in a remote area or in a distance. There is a possibility to add remote control to your remote monitoring. This will enable you to change key parameters on your equipment from distance.



  • Support by Alfa Laval experts
  • Faster and more accurate troubleshooting
  • Faster return to service in case of problems
  • Access your equipment remotely to see operating data

Rotating Feed Zone also known as VecFlow in Wastewater applications:

The VecFlow feature for dewatering and thickening decanters minimizes turbulence in the bowl by gently accelerating the feed at a speed lower than full speed due to its unique design. This means that the solids to be separated are not that likely to break up when being accelerated (entering the machine). The result is approximately 20% lower power consumption and higher separation capacity compared to other decanter centrifuges.


  • Least power consumption

  • Reduced polymer consumption

  • Improved separation

Cost Calculator

Cost Calculator for Alfa Laval Decanters

The Cost Calculator is an add-on to Remote Support & Monitoring that helps optimize operating cost. The Cost Calculator algorithms make a real-time calculation of your operating cost based on live operating data and factors such as the price for polymer and power. The Cost Calculator clarifies the impact that different actions have on operating cost and increases awareness among the staff.



  • Lower operating costs with increased cost awareness
  • Immediate information on how different settings on your decanter affect cost
  • Identify and share best practices between sites and decanters
