Stainless steel tanks for water treatment with ion-exchange resins

3.5 Commissioning - preparing the filter media

The easiest way to fill a filter medium into the ion
exchange tank is by using a funnel with a large
opening.
A funnel for filling the filter media is available from
elector under article code 44101.
Open the tank, place the funnel on the opening and fill
in the filter material while shaking the tank.
The filter material is distributed and compacted by
shaking the tank. Alternatively, you can use a vibrating
plate.
The tank should be filled with filter material up to just
above the upper pipe of the water supply.

3.6 Operation -Fill with water, bleed and rinse

Close the tank after observing the instructions in 3.1.
Make sure that there is a flat gasket with the safety
sieve underneath the double nipple at the outlet
connection.
Connect the water inlet and water outlet and fill the
tank with water.
Pull the ventilation valve upwards to vent the tank.
Vent the tank carefully, trapped air bubbles can
severely restrict the function of ion-exchange resins in
particular.
Do not operate the ion exchange tank from bottom to
top when using mixed-bed resins. This can cause the
resins to separate.
New and regenerated filter media mostly have contaminants. Therefore, the filter should be rinsed
twice with the container volume after venting.

3.7 Flow rate

The flow rate is based on the application. This usually ranges between 5 and 40 BV/h (bed volume per
hour). With a 40 liter container, 40 BV/h corresponds to a flow rate of 1600 liters / hour (40 liters x 40
BV).
