How to boost treatment efficiency with sensors

Wastewater treatment requires considerable amounts of energy. The installation and operation of water quality sensors at wastewater treatment plants can significantly improve water quality and the stability of treatment processes, while cutting costs by reducing the consumption of energy and chemicals.

Cost savings of 20% or more can be achieved with the help of suitable sensor technologies, proving that carbon footprint reduction and cost-savings go hand in hand.

The best way to reduce both the costs and carbon footprint of a wastewater treatment system is to reduce energy demand without compromising on water quality and services. Smart use of sensor technologies helps to achieve exactly this.


A wastewater utility can reduce energy use by more than 20% by optimising its active sludge process.


The anticipated investment costs of approx. 100-150 k€ can be recovered in less than 9 months.


The implementation of sensors for active sludge treatment optimisation leads to a 25% reduction in methane and laughing gas formation, both potent greenhouse gases.
