Product catalog summary

Overview: The Tsurumi FHP-series floating decanters are designed for the efficient discharge of supernatant liquid in Sequencing Batch Reactors (SBR). These decanters are particularly effective in environments with unstable water levels, ensuring only supernatant liquid is discharged while preventing sludge inflow.

Specifications: The FHP-series includes models with varying motor outputs ranging from 0.25 kW to 1.5 kW, operating at speeds of 3000/3600 min-1. The discharge bore sizes are 40 mm, 50 mm, and 80 mm, suitable for treated water with temperatures between 0 to 40°C. The pumps feature a dry type submersible induction motor with a double mechanical seal and double-shielded ball bearings.

Features: Key features include a photosensor that prevents sludge inflow, an anti-sludge sensor that stops the pump when sludge is detected, and a float that maintains the pump's position. The sensor cleaner ensures the sensor surfaces remain clean by washing them with pressurized water.

Applications: These decanters are ideal for facilities requiring the discharge of supernatant liquid, particularly in processes where water levels fluctuate significantly.

Components: Major components include the float made of fiber-reinforced plastic, an intake check ball to prevent sludge inflow, and a sensor cleaner for maintaining sensor accuracy. The pumps also come with standard accessories like a guide rail fitting set and optional accessories such as a sensor cleaner and discharge hose.

Performance: Performance curves are provided for different models, indicating the relationship between capacity and total head at various speeds. The pumps are designed to operate efficiently under specified conditions, with built-in protection devices like a circle thermal protector.

Recommendations: It is recommended to perform sensor cleaning for 5 minutes every 1.5 hours during the aeration process, with water flow regulated between 10 to 20 L/min and pressure between 0.5 to 1 kg/cm².

I Photosensor prevents sludge inflow, helps discharge only supernatant liquid. Ideal for use under unstable water levels. Major Components & Specifications Performance Curves Features • The sludge surface monitoring device prevents unexpected inflow of sludge and helps the pump solely discharge supernatant liquid. • A float makes the pump particularly useful for the application where the water level fluctuates widely. • An incorporated control circuit automatically stops operation upon receiving warning signals from the photosensor which would detect a water level drop to near the sludge interface...

The float sustains a submersible pump by buoyancy at an appropriate position. Made of fiber reinforced plastic (FRP), the float is filled with polystyrene foam which prevents the loss of buoyancy in case the float is broken. Anti-sludge Sensor Cable Amplifier Unit Box Guide Support Float 1 Guide Hook Sensor Cleaning Hose (not supplied) Intake Check Ball A check ball incorporated in the intake closes the suction mouth by buoyancy when the pump stops operating thus preventing the inflow of floating sludge. During operation, the ball is sucked in by the pump’s suction power to take in supernatant...
