3.2 Intended purpose
The polymer preparing and dosing station EASYPURE Powder and Liquid
is intended for the following purpose: Generation of a polymer solution to
be used as a powder polymer flocculation aid or a fluid concentrate with
drinking water. Provision of the polymer solution in a metering chamber.
Both basis solutions and ready-to-use solutions with pre-determined
concentrations can be prepared. The pre-set concentration threshold
amounts to 0.3 – 0.6 %.
The system can be used to generate salt or coagulant solution which do
not present large amounts of soiling.
3.3 Device revision
This operating instructions apply to the following devices:
Device Month / year of
manufacture
EASYPURE 02/2014 onwards

3.4 Prohibited dosing media
This device serves the preparation of solutions which do not damage the
device. Each individual product requires calculations and preparations.All
chemicals used must be approved by the manufacturer.
The viscosity of the solution may not exceed 2500 mPas in standard
designs. The gear agitator design enables a viscosity of max. 5000 mPas
3.5 Water quality

4.2.2 Function description
EASYPURE Powder and Liquid is a fully-automatic system for the
continuous preparation of dosing solutions consisting of water and dry
substances.
The dry feed is shaken into the dry feeder (5) supply hopper (6). Working
in automatic operation, the dry feeder doses the amount of dry feed
required for the concentration set into the suspensomat (4). Should the
dry feeder approach empty, an alarm message is issued to the control.

The preparation water (1) is fed into the system via the water equipment.
The pressure reducer (14) maintains the operating pressure in the
permissible range The solenoid valve (15) opens and closed the water
supply automatically. The current flow volume is monitored by the flow
meter (16). An alarm message is issued to the control following a water
shortage. The water supply can be shut off manually with the ball valve
(13).

Fig. 3: Jet fittings
The water supply splits into a filling valve (17) via which the water flows
into the preparation chamber and into a bypass to the suspensomat (18).
Dry substances from the dry feeder (5) are wetted in the suspensomat so
that they can be distributed homogeneously upon entry into the
preparation chamber.

19
Fig. 4: Suspensomat setting valves
The water is fed into the suspensomat via two separate injection jets.The
dry feed is wetted thoroughly and evenly via the injection jets in two
stages. The setting of the upper and lower injection jets can be performed
manually via the two valves (19 and 20).
The dosing solution is prepared in a container divided into three
chambers. Preparation, maturing and withdrawal (dosing) is performed in
an uninterrupted, continual process. An agitator is installed in both the
preparation and maturing chamber to support the solution process
through stirring. The system is optionally available with an agitator in the
dosing chamber.
After the dry feed is dissolved in the first chamber, the solution moves
across the dividing wall into the second chamber (maturing chamber).
The maturing time available for generating a basis solution depends on
the withdrawal volume and the capacity of the system. With a maximum
withdrawal volume, it amounts to c. 60 minutes.
The set solution is then displaced into the third chamber (dosing
chamber). An ultrasonic sensor fitted in the dosing chamber regulates
automatic operation using the various fill levels (see the formula in
chapter 4.2.2.1 „Function sequence in automatic operation.“ on page
11).
i
The displacement process can lead to minimal mixing of the
fresh and matured solutions in the threshold zones. The
immature solution can thus enter the dosing chamber. The
amount is extremely small. Nevertheless this should be taken
into account in process requiring absolutely matured
solutions.
The finished solution is ready for withdrawal and further dosing from one
or more dosing pumps. The dosing pumps are not part of the system
EASYPURE, but can be controlled with the system control and thus be
integrated in automatic operation.
