Tsurumi Floating Decanters FHP
Tsurumi Floating Decanters FHP are designed for efficient supernatant discharge in sequencing batch reactors (SBR) and water treatment systems where surface clarity is important. They ensure precise, sludge-free removal, even with unstable water levels, using advanced sensors and float-based pumping technology.
The Tsurumi Floating Decanters FHP are specially engineered for the efficient discharge of supernatant liquid in sequencing batch reactors (SBR) and other water treatment systems where surface-level clarity matters. These decanters ensure precise, sludge-free supernatant removal, even under unstable water levels, thanks to advanced sensor control and float-based pumping technology.
Key Features
-
Photosensor-based sludge detection: Automatically prevents sludge inflow by detecting turbidity near the sludge interface.
-
Floating submersible pump: Made from FRP (Fiber Reinforced Plastic) with polystyrene foam core to maintain buoyancy even if damaged.
-
Anti-sludge intake check ball: Prevents sludge backflow when the pump stops.
-
Sensor cleaner: Sprays treated water at regular intervals to maintain accurate sensing performance.
-
Automatic stop/start via amplifier and control unit upon water level changes.
-
Suitable for facilities with fluctuating water levels.
Applications
-
Supernatant discharge in Sequencing Batch Reactors (SBR)
-
Municipal and industrial wastewater treatment plants
-
Processes requiring clear liquid removal above sludge layers
