Since the early 1960s, effluent water quality has been improved through public and private investments prescribed by the Clean Water Act. But despite the improvements, much of the existing wastewater infrastructure is deteriorating faster than it can be replaced, due to budget restrictions. An estimated 21,604 publicly owned treatment plants provide wastewater collection, treatment, and disposal services to 226.4 million people in the United States. During which, they generate about 8 million tons of sludge annually. Sludge requires significant energy to manage, and typically consumes 30% to 80% of the total electricity used by wastewater treatment operators. The chemical additions of ferric salt and lime enhances the coagulation and sedimentation processes that improve the removal of solid materials. At this lime slurry manufacturer, an EchoPod ultrasonic level sensor and PodView level indicator are used to monitor calcium hydroxide in their bulk storage tanks. EchoPod is programmed with the WebCal software linearization feature to output tank volume in gallons, which is then displayed on the PodView indicator for use in the filling of delivery trucks.
