DESCRIPTION
2.1 Description
These filters have been designed to provide water in
pools and aquatic parks, also for all water treatments
that require the elimination of suspended matter using
the proper reduction of filtration element.
Apart from the filter itself, filtration and purification
process include some points that must be taken into
consideration as they can influence the correct filter
operation. These would be chemical water treatment,
pump equipment, pipe segments and general hydraulic
design.
When public pools are concerned, the current rules in
each country should be observed, as the installation
must follow them.
The filtration quality depends on different parameters as
depth of filtration bed, characteristics, quality and grade
of filtration media, etc., as well as filtration rate.
