1. Introduction

Flocculators are studied both to optimize the dosing of coagulants in order to separate the pollutions in water treatment
plants, thanks to the laboratory valuation results obtained with the so-called Jar Test.
It is possible to set the stirring speed (1) in analogical way and the stirring time (2) by knobs placed on the frontal panel.
The examined samples can be lighted by a back fluorescent lamp controlled by a switch located on front panel.
FP4 was developed for optimum use in the field; the instrument can run both connected to a normal battery and a car's
cigarette lighter.

1. Stirring Knob
The steel structure epoxy painted is studied and tested in order to give to the instrument an excellent resistance to the
attack of chemical agents and to corrosion in general. The external power supply allows the instrument to be connected to
all frequencies and voltages in the world (100÷240V / 50÷60Hz).
It's possible to select the stirring speed (20-40-50-100-200 rpm), the operating time and the lighting of central column by the
frontal panel. The stirring speed is the same for each position. It is possible to set the time of running from 0 to 30 minutes
and the central column start up. FP4 is characterized by a non-skid base so as to keep the beakers stable during operation.

2. Assembly and installation

Upon receipt and after having removed the packaging, please check the integrity of the instrument. The box includes:
•
FP4 Portable Flocculator
•
Plug for power supply

2.1 Electrical connection

Before connecting the instrument to the power supply, make sure that the values on the rating plate correspond to those of
the power supply. Connect the unit to the power supply using the transformer supplied.
Ensure that the socket and the relative cut-off device conform to current safety norms and easy to reach.

2.2 Start-up

Rotate the speed knob completely to the left. Place the beakers containing the sample and then, set the speed and time by
turning the knobs.

2.3 Information about construction materials

Structure Aluminum

3. Operating controls

It's possible to select the desired stirrer speed by the knob "Stirrer rpm" on the frontal panel. It's possible to choose the
desired values: 0-20-40-50-100-200 rpm by using the information written on the analogical scale around the knob.
The start-up and the selection of the running time with automatic turn off are made by the relative timer knob:
by turning un-clockwise the timer knob on the manual modality the instrument runs in continuous way;
by turning clockwise the timer knob it's possible to select the time of running up to 30 minutes; the stirring automatically
stops as the time finishes.
At the end of the work cycle set the stirring speed knob on "0" rpm, the timer knob on "OFF" and turn off the light of centra l
column. If the instrument is not used for a long period it's better to disconnect the external power supply from the plug.
