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.

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.

Fig. 2: Water equipment
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.
20
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.

WARNING
Increased risk of accidents due to insufficient qualifica-
tion of personnel!
This device and its accessories may only be installed, operated and
maintained by personnel with sufficient qualifications. Insufficient
qualification will increase the risk of accidents.
ðEnsure that all action is taken only by personnel with sufficient and
corresponding qualifications.
ðPrevent access to the system for unauthorised persons.
WARNING
Danger of personal injury and material damage!
The device is extremely heavy. The failure to take adequate safety
precautions during transportation and to act with caution can lead to
accidents involving personal injuries and damage to property. Limbs
can be crushed when the device is set up.
ðTransport the device using a floor conveyor that is suitable for the
load such as a pallet truck, forklift truck or crane.
ðWear safety shoes while transporting the device.
Note
Damage to the system due to incorrect installation
The failure to observe installation instructions (e.g. use of unsuitable
tools, incorrect torque) can damage the system parts.
ðUse suitable tools.
ðNote the specified torque.
7.1 Installation location
nA base with a maximum incline of 1:200 is recommended on which to
set-up the device.
nThe system must be accessible for operation, maintenance and filling
with dosing medium
7.2 Hydraulic installations
Note
Soiling from water of an insufficient quality
The use of water from the cleaning process or other water with insuffi-
cient cleaning leads to soiling of the pressure-relief valve and
flocculate deposit on the chambers. This results in increased soiling in
the system and increases the maintenance requirements.
ðThe water used must be of a quality similar to drinking water. It
should be free of solids and suspended matter.
Precondition for action:
üThe device is not filled.
üThe system has been disconnected electrically and is protected
against reconnecting.
Perform the following working steps:
1. Close the water supply on the input of the water equipment.
i
Size of the connections see chapter 5.4 „Connection
dimensions“ on page 14.
2. Install a pipe disconnecter in the drinking water supply if the local
conditions require it.
3. Connect the dosing pump suction line to the dosing chamber output.
4. Connect the overflow pipe and lead the pipe in a suitable outflow
