Why detect sludge blanket level in your treatment process?
Sludge blanket detection in water treatment plants is a critical process to monitor and control the settling of solids in sedimentation tanks or clarifiers. The sludge blanket refers to the layer of settled solids that accumulates at the bottom of these tanks. Inadequate monitoring poses risks of solid carryover, compromising water quality, increasing turbidity, and potentially impacting downstream equipment like filters. Timely sludge detection mitigates equipment wear, operational issues, and allows for corrective actions. Regular removal or recirculation is crucial for plant efficiency, preventing overflows and ensuring proper functionality. Automated sludge level detection enhances real-time monitoring and control, optimizing overall operational efficiency. In summary, sludge blanket detection is vital for maintaining the effectiveness and reliability of water treatment plants. It helps optimize treatment processes, prevent operational issues, and ensure the production of high-quality treated water.
Main applications of sludge blanket sensor
The VB5 sensor can be used in both handheld and on-line applications. For spot measurements, it allows operators to check their sludge levels and concentrations at various points in the treatment process. It’s also very useful for monitoring and controlling septic tanks. For online applications, it’s a simple and efficient sludge level detector by monitoring the interface between sludge and water, allowing action to be taken when needed. It can also monitor concentrations in sludge treatment, allowing correct dilution or polymer injection control prior to sludge dewatering steps.
Measurement principle of Aqualabo’s VB5 probe
Aqualabo’s VB5 uses optical transmittance measurement in the infrared spectrum, operating at 870 nm, it measures the signal over a 5mm optical path. With temperature-regulated optics, the probe guarantees accuracy even with process variations. The measurement is given in % of light transmittance through the sludge ranging from 0 to 100%.
Why use and trust Aqualabo’s VB5 for sludge blanket detection
The VB5 sensor is ideal for harsh environments such as wastewater treatment. The rugged construction ensures durability and stability of measurement over time. The efficiency of the measurement and its simplicity gives you an excellent and competitive tool to improve your sludge management. Finally, the pre-amplified signal and Modbus communication ensure seamless integration into your process with the guarantee of no interference in the signal and readings.
FAQ VB5 Sensor
Does the VB5 sensor require any consumables or maintenance?
As an optical sensor, the VB5 requires no consumables. The only care required is to keep the optical lenses clean to avoid any drift in the measurement.
How does the VB5 ensure measurement accuracy under varying conditions?
The VB5's optical technology, equipped with temperature-controlled optics, pre-amplified signal and digital communication, contributes to high accuracy even under fluctuating environmental conditions.
Does the VB5 require calibration?
Yes, you can calibrate the VB5 sensor in 1 point by immersing the sensor in distilled water to simulate 100% IR light transmission. This operation also makes it possible to check the cleanliness of the optical windows.
