Hycontrol Sludge Blanket Level

The Sonarflex Sonar, sludge blanket and interface controller is a microprocessor based transmitter combined with a high power multi frequency sonar transducer and an automatic cleaning mechanism.

Sonarflex is used to monitor and control the blanket level in settlement tanks for a wide range of industries on applications including:-

• Primary Sedimentation - Sludge blanket levels
• Secondary and Final Clarifiers - RAS blanket / FLOC level / Clarity
• Sludge Thickeners - Settling blanket level / Clarity suspended solids
• DAF Tanks - Settling blanket Level / Floating bed level
• Sequential Batch Reactors (SBR) - Settling blanket level / RAS blanket
• Lammella clarifiers- Settling blanket level / Clarity suspended solids
• Counter current decantation (CCD) tanks - Blanket level / FLOC / Clarity
• Mining and Process settling ponds, lagoons, tailings dams, carbon columnsPRINCIPLE OF OPERATION

• The Sonarflex transducer initiates a high powered acoustic pulse through the water (liquid) towards the blanket/interface at the bottom of the tank. The pulse is then reflected off the RAS or BED layer (blanket/interface) back to the Sonar Transducer, and is then processed by the transmitter. The specialist software then provides data relating to the RAS level, FLOC/FLUFF level, temperature in the tank and a basic guide to clarity if required.

  Dual analogue outputs and COMMS based outputs are available to track both the RAS and FLOC layers simultaneously. This feature helps to identify other stratified interfaces or the FLUFF/FLOC layer (where such an interface moves independently of the sludge blanket/bed level and needs to be monitored to prevent overflow into the launders).

  The Sonarflex processing software monitors the operating efficiency of the sonar transducer. As the efficiency drops off, due to build-up of scum, air bubbles, scaling, or fats, etc., on the transducer face, the automatic cleaning mechanism operates and restores the sonar transducer to its optimum efficiency.

         FEATURES

• Full range of transducers to optimize detection of heavy and light density interfaces.
• Simple and easy calibration to track specific densities.
• Four simultaneous outputs for RAS level, FLOC level, Clarity (suspended solids) and Temperature, with COMMS option.
• Industrial scum cleaning mechanisms that do not require maintenance. No wiper blade assemblies to wear and change.
• Radio link option for off bridge transmission of data.
• ATEX hazardous area options for enclosed vessels.
• 500 metre separation possible between transducer and transmitter.
• VISION system II, Modbus, Profibus DP/PA, Foundation Fieldbus, DeviceNet, HART COMMS capability.
• Multiple outputs with 3 relays for alarm and control output plus indication of cleaner operation.
• GSM module enables remote diagnostic support from Hycontrol service engineer.
