Sewage Moisture

Sewage treatment plants discharge cake or sludge, a biosolid that is 70-80% water. The rest is a nutrient-rich organic material that has value as a renewable energy source or for blending in soil composts for agricultural soil conditioning, reducing the need for fertilizer.


To be properly processed, the exact moisture content of the sludge must be known within 0.5-1%. The sludge can be burned to recover the energy; however, it must be dry enough to incinerate. Measuring the moisture becomes key.

Monitor Sewage Moisture with MoistTech’s IR-3000 Moisture Sensor

MoistTech provides moisture sensors to monitor the moisture content during the drying process. The IR-3000 is a near infrared online moisture detector (with software) system which is designed to measure the moisture in the sewage drying process. It gives you complete control in real time because the sensor provides non-contact measurement. Mount the IR-3000 above your production line.

Control Sewage Moisture Closely with the Highly Accurate IR-3000

Better accuracy of information during the drying process allows you to have a better product and to control production costs more closely. The IR-3000’s sensor calibrations, measurement wavelengths, algorithms, and sensor optical requirements to measure sewage moisture are pre-set at the factory. No further recalibration on-site is necessary, not even maintenance, making accuracy in the field nearly effortless.


Typical moisture accuracy is about ± 0.05%, with coating accuracy varying from 0.1 to 0.01 micron, depending on the coating type. A typical analog range is 0-10% moisture. The outputs can be adjusted to optimize recording requirements or PLC.

Relish the Up-Time of This Durable Sensor

The IR-3000 was designed and built to outperform the competition by providing long-term, reliable performance in even the harshest industrial environment. It is unaffected by:
