Continuous Sludge Blanket Level Monitoring
The SludgeWatch Ultra utilises the industry accepted look down ultrasonic or 'sonar' method of detecting and tracking the interface between sludge and water in water, wastewater and industrial effluent settlement tanks and clarifiers. The easy to use system has been specifically designed for these applications and makes use of an easy drop down menu structure to allow hassle free site configuration.
The self-cleaning transducer can monitor the interface in applications where the sludge has a density of 0.5% or more. The cleaning wiper operates automatically to remove dirt and air bubbles that can interfere with the measurement.
By monitoring the position of the sludge/water interface the user can make process adjustments to ensure that their plant is operating at the optimum efficiency whilst ensuring that water quality is preserved. If a blanket is allowed to rise too high in the tank there is a danger of carry-over to the effluent channel or the next processing stage, additionally strain may be placed on the scrapper mechanism. If there is too little sludge in the tank the settling process cannot work effectively, this leads to problems with sludge processing, returned sludge concentrations and again carry-over to the effluent channel.
Automated sludge blanket detection removes the need for time consuming manual checks, ensuring reliable process control everyday and during unexpected weather or load conditions.
