Sonar technology deployed to map wastewater sludge levels

摘要

The use of sonar technology could "transform" the way in which sludge build-up in settlement ponds and lagoons is monitored and maintained, according to waste management specialist CSG. Lagoons are an established method for treating wastewaters created by site processes such as those performed at oil refineries, petrochemical works, AD plants, sewage treatment works, reservoirs and many other industries. Some are created to be used for the clarification of water while others act as settling ponds where solids are separated. Treated water from the ponds is often re-used in on-site processes.
