2. Applications
EchoSmart is suitable for most municipal and industrial liquid/solid separation processes in
which a reliable measurement of the level of a solids or suspended-solids blanket is desired.
Typical applications include municipal and industrial wastewater and water treatment
clarifiers and gravity thickeners. Sensors with optional turbidity measurement are available
for applications in which a 0-50 NTU turbidity indication at the location of the sensor is
desired. A broad range of industrial process applications are also appropriate. Self-cleaning
sensors and special design sensors to accommodate high temperature and exposure to
chemical environments are available.
2.1.
Wastewater and Water Treatment Clarifiers and Thickeners
EchoSmart instruments are most frequently implemented to provide reliable sludge
blanket level measurements in municipal wastewater and water treatment operations.
Instruments are suitable for circular and rectangular basins, uncovered and covered
tanks, and those with both fixed and traveling bridge arrangements. Mounting
arrangements easily accommodate surface skimmers and rakes. Automatic signal
control functions adapt to differences in sludge density that typically occur in primary,
secondary and final clarifiers, and gravity thickeners.
Instruments are also effective in granular media gravity and pressure filters for
conditional backwash control. Measurements include media level and expansion, and
above filter turbidity (backwash turbidity).
2.2.
Industrial Wastewater and Raw Water Treatment
EchoSmart is effective in providing sludge level measurements in a wide range of
industrial water treatment applications. Raw water from a surface water source is often
sent to a clarifier for particulate removal prior to introduction to plant processes. Water
spent in plant processes often requires primary, and even secondary treatment prior to
being directed to a municipal plant for further processing or being discharged in the
environment. EchoSmart sludge level measurements can be used to effectively control
clarifier solids blow-down, optimize chemical application, and limit solids discharge
in the effluent stream.

Industrial Process Applications
Suitable process applications are found in the Power Generation, Mining and Mineral
Processing, Chemical, Pulp and Paper and other process industries. Contact Entech
Design or an authorized representative for further information on the characteristics
and requirements for successful implementation of EchoSmart equipment in these
environments.
