3.1 Technical information
Take note of the following sections:
3.1.1 Separation
The best separation efficiency is attained with a low viscosity of the product to
be separated.
In the case of deviating products
– see sales documents or
– consult the factory.
Water seal (only for OTC …-02…)
•
The water seal which prevents light phase from discharging through the water
discharge must be maintained during separation. See section 3.2.
3.1.2 General information on cleaning the bowl
When must the bowl be cleaned?
The intervals at which the bowl must be cleaned depend on the solids content
and nature of the product.
The time between the cleaning cycles (separating time) can be determined by
experiment as follows:
Before beginning the test, the solids holding space of the bowl must be
free from solids.
•
Separator:
– adjust to the desired throughput capacity and
– feed a certain product volume for a certain time (3 or 5 hours – depending
on the degree of contamination of the product).
•
Shut down the separator (see section 3.5).
•
Remove the bowl shell (see section 4.4).
•
The intervals at which cleaning must take place can be determined by the
volume of solids accumulated in the solids holding space. It must be taken
into consideration that cleaning must take place before the solids holding
space is filled to the brim as otherwise the separation efficiency will deterio-
rate.
•
When product with a different solids content is to be separated, it is recom-
mended to repeat the test after cleaning the bowl.
•
Unusually long separating times are only possible when the solids content in
the product is low.
