The unique design of the Monroe 3–axis pivoting scum wiper blade ensures constant contact with the scum beach, providing the highest scum removal efficiency possible. Thickener Designs Monroe can provide internals only for concrete tanks or totally integrated steel
The sonar system was supplied with an automated scum cleaner, that operated every 5 minutes. The ORCA sonar transmitter provided two analogue outputs. The first was the “bed level” output and the second was the “clarity” of the water (suspended solids)
Scum suppression: Various scum suppression methods are available to ensure clear overflow. Drive mechanism: A wide range of hydraulic and electric drive mechanisms are ... the entire system is located inside a thickener tank and makes use of internal overflow liquor for dilution
of blended scum flow. Each tank is fabricated from ¼” minimum thickness carbon steel and discharges scum to a mixed and heated holding tank. The scum collector chain is malleable iron and the flights are redwood. Each holding tank is fabricated from ¼” minimum thickness carbon steel and has nominal dimensions of 6’ diameter177KB
The tailings thickeners efficiency has improved due to feedback on settling characteristics from the sonar transmitter. The ORCA sonar has its own automatic scum cleaning system that is guaranteed for 5 years. Commissioning time required for the sonar was 10 minutes.
