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.

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).

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.
