Cerlic ITX TSS sensor
The Cerlic ITX sensor uses near-infrared (NIR) technology to measure total suspended solids (up to 2%) in activated sludge processes. Unlike turbidity sensors designed for clean water processes, the sensor utilises transmission of light for concentration measurement, which means it is immune to changes in water colour.
The submersible sensor has a self-cleaning system completely integrated into the body of the unit. It has no moving parts and uses pressurised water (eg, re-use water) or compressed air (eg, from blowers). The handrail mounting assembly and 4 m fibreglass telescopic mounting rod are designed to shake with the user’s aeration to help reduce ragging. The sensor is calibrated against regular tap water (zero) and a single lab sample.
As part of the Cerlic family of online suspended solids, dissolved oxygen, pH and biosolids sensors, the product communicates in real time to the user’s SCADA with a choice of 4-20 mA or Profibus DP. Up to four sensors can be controlled (including cleaning cycles) from the one BB2 transmitter.
When compared with typical sample lab testing, the product is said to provide ±0.5% full-scale accuracy to dry-weight results. With low maintenance and a long life expectancy, the sensor can help bring real-time control of MLSS to the user’s plant.
