Hawk Measurement Systems Sultan Sonar System sludge blanket level sensor

The Australian designed and built Sultan Sonar from Hawk Measurement Systems is a fourth-generation high-power/low-frequency sludge blanket level sensor for use in water clarifiers.

Operators of potable and wastewater treatment plants need to constantly balance biological and hydraulic parameters throughout their process. Maintaining the correct level of sludge build-up in clarifiers is critical for energy efficiency, bacterial action and processed water quality.

Mounted to the clarifier’s handrail, the product eliminates the hazards associated with manual dip sampling techniques like lowering a gap sensor. The focused high-power/low-frequency beam penetrates through suspended solids and detects the stratified layers of settling organic material, from sludge bed to lightest flocculent layer.

Self-cleaning and easily integrated into a plant’s control systems, the device is supplied precalibrated for various densities of compacted bed, hindered, free settling and Floc zones, and requires no ongoing maintenance.
