Sludge Moisture

ROI From Moisture Measurement

The IR3000 incorporates MoistTech’s new low wavelength technology developed specifically for the measurement of liquid and sludge products in a pipeline, after the filter press and on conveyors. Additionally, the sensor utilizes MoistTech’s sapphire optical window sampler viewer which is designed for online installation and to withstand a variety of process conditions regarding temperature and pressure.

With the MoistTech’s sewage online moisture monitoring system treatment plants are saving money in energy & landfill transportation costs. We recommend installing a sensor after the feeder press, prior to dryer or after the filter press for disposal to reduce shipping charges and environmental problems. In the case of incineration, we recommend installation prior to the drum dryer where solids are controlled to approximately 12%.

Calculate Potential ROI with MoistTech

Dryer Control

Efficiency is a top of the line priority for manufacturers and the dryer can drain a lot of that. Measuring the moisture before and after the dryer allows the user to optimize the dryer settings to save time and money. A proper moisture control system will pay for itself with the energy savings from the dryer in less than 30 days. Efficiently controlling the dryer within the facility can drastically change the productivity levels.

The sensor(s) can be located throughout the sewage process and can be directly connected to the users PLC or any laptop. Ethernet and 4-20 ma are included as well as our high-tech Windows operating software. DPM (Digital Panel Meter) and a Color Touch Screen Operator Interface are also available as read-out options.

Unsurpassed in performance, our sensors can accurately measure  moisture within tenths of a percent of most applications


MoistTech sensors withstand the test of time and are low to zero maintenance


Rely on MoistTech’s NIR moisture sensors to never drift or need re-calibration


A moisture measurement system is essential for the production process and in some cases will pay for itself in less than 30 days

The Only Solution

With the help of industry partners and 40 years of knowledge and experience, MoistTech has developed the IR 3000 Moisture Sensor that is ideally suited to measure the moisture levels in high moisture sewage to provide cost savings to sewage treatment plants worldwide.

Unlike other instrumentation of this type, some of the unique features of the IR3000 is that it can monitor the product even with small gaps in product flow and is unaffected by ambient light without impacting the accuracy. The model 3000 is also ideal for installations on chain and screw conveyors.

Sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is +/- 0.5% and over a range of 75-90% moisture.


Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.

Remember this could involve more than one installation point!


A closed loop process is achieved by incorporating a moisture measurement system into the manufacturing process. Developing a proactive solution to moisture control will avoid costly downfalls. 


MoistTech’s experts will assess your specific application with lab tests, calibrations and accuracy results to ensure our equipment will peform for you. All of our sensors are pre-calibrated prior to being shipped to create a plug-and-play operation for the end-user.

Understand the Process

MoistTech’s The IR-3000 moisture sensor is a Near-Infrared online moisture senor for instant, non-contact measurement of virtually any product and raw material in the harshest manufacturing environments. Unsurpassed in performance, stability, reliability, maintainability and cost of ownership the IR-3000 is the answer to controlling moisture in your product.

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.
