Automatic Sludge Blanket Level Detector for Water and Waste Water

The ASLD2200 is a fully automatic sludge blanket level detector designed for the water and waste water industry. It utilises a servo-driven sensor which continually tracks the settled interface with the sensor at the very top of the interface zone. Continuous monitoring of the sludge/water interface or sludge blanket is central to the efficient operation of clarifiers, thickeners and settlement tanks. Reliable measurement enables a control system to maintain the optimum depth of sludge in the tank. A sludge interface…

Ultrasonic Sludge Blanket Level Monitoring

The SludgeWatch Ultra utilizes 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 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. If a blanket is allowed…

Fixed Sludge Blanket Level In Clarifiers And Settlement Tanks

The SludgeWatch 8200w² Monitor provides a reliable method of detecting the sludge blanket level in clarifiers and settlement tanks, or increasing levels of suspended solids or sludge density in large range of processes. Control of the sludge blanket level is essential to ensure discharge consent compliance and efficient control of the treatment process. If the sludge blanket in a settlement tank is allowed to rise close to the surface there is a danger that solids will leave the tank and…

Portable Sludge Blanket Detection

The SludgeWatch 715 provides a simple, low cost method of spot checking the sludge blanket level in a wide variety of settlement tanks. The cable reel design removes the need for any additional carrying bag. The sludge blanket is detected by winding the sensor down into the tank, the audible tone will change and the LED illuminates once the sensor has reached the blanket. This method of sludge blanket detection offer major improvements over traditional SludgeJudge type systems in terms…
