DLM recently introduced the MSL600 sludge blanket monitor that is a microprocessor-based system, with an abundant range of built-in, display, control and alarm features. Easy to use menu driven programming allows complete configuration of the unit.
Local programming is carried out via a membrane keyboard. The MSL600 uses the sonar principle, with an ultrasonic pulse transmitted under water. Sophisticated echo processing allows the MSL600 to analyse the pulse of ultrasound, which is transmitted vertically and reflects from the surface of the sludge blanket. The system captures the ultrasonic echoes reflected from the blanket interface.
Knowing the speed of sound in the supernatant the depth of the sludge blanket is then determined from the time of flight of the echo. The system comprises an ultrasonic transducer and a bridge mounted control unit. These are specially designed for easy installation on a clarifier tank bridge using a mounting bracket, supplied with the system.
Applications would include: primary and secondary clarifiers in wastewater applications, circular rotating or static clarifiers, rectangular clarifiers with moving or static bridges, most Lamella clarifiers, picket fence thickener sludge blanket level. The monitor includes a human machine interface, integral radio link, and features a self-cleaning sensor.
Level measurement of an acid dosing tank at a WWTP
Level Measurement & Control
Ferric chloride and other acids are essential chemical substances in water and wastewater treatment. To control the dosing of acid solutions, an Australian wastewater treatment plant uses a special container to store, mix and add these chemicals. The company opted in favour of KROHNE’s OPTIWAVE 1540 radar level transmitter

Level Measurement & Control
A municipal utility in eastern Germany operates a state-of-the-art wastewater treatment plant with sustainable sludge treatment. The ultrasonic signal was being partially deflected by the wind, leading to frequent false measurements and inefficient process workflows. The problem was solved by replaced the ultrasonic level sensor with KROHNE’s OPTIWAVE 1540 non-contact radar.
