Wastewater treatment plants are major energy users, and efficient operation requires a fine balance between biological and hydraulic parameters.Maintaining that balance can be daunting. It depends on reliable and meaningful data in critical parts of the process, such as the primary and secondary clarifiers and thickeners.Accurate measurement of floc and high-density sludge levels is challenging in murky, turbid settling tanks.Today, advanced sonar measurement devices can provide such accuracy, helping to improve process control, enhance permit compliance consistency, save energy and extend equipment life.Complex pictureEven with extensive sample extraction and lab analysis, it is difficult to obtain a clear picture of the
