Flocculator - PRTPC1
The PRTPC1 type is installed on medium and large size treatment plants and consists of a mobile girder used as walkway, a lateral traction trolley, a control unit, a gear motor, a slewing ring unit, a central cylinder defining the flocculation compartment, a turbine with exclusive airfoil blades, a logarithmic airfoil bottom scraper blade, a scum box, a skimming blade, a peripheral deflector and a notch weir. The control unit, placed at the periphery, drives the walkways around a central axis, in correspondence of which the slewing ring-turbine assembly will be fitted on. The presence of a suitable central recycle zone and of the flocculation compartment allows the adequate coagulation and flocculation of the water which completes the clarification in the most external area.The sludge scraper blades remove the sludge precipitated on the sloping bottom of the tank and gather it into a toroidal ditch wherefrom it will be removed. The system, consisting of skimming blade, scum baffles and scum box, allows the removal of any floating materials.
