"KASTALIA" gravel filters are also a graded grain size filtering media filters (sand or others).
Its construction, operation and backwash is identical to “G” gravel filter but, as its drum is horizontal, the surface of filtering media is increased and we obtain a higher capacity, with the same flow rate, and a better filtration for same capacity. Filtrated water, after filtration, has a cleaning effect up to 3 microns floating particles. Recommended flow speed 50 m/h.
Backwash as standard is manual. The system may be supplied with full automatic backwash control, upon request.
CONSTRUCTION: The body of the filter is constructed by high quality carbon steel sheet and it is supplied, as standard, epoxy coated. It can be supplied in stainless steel or galvanized steel upon request.
The upper cover is equipped with a manhole for filter media filling and a similar manhole exists on bottom lateral side for discharging filtering media (sand etc.) On top of the filter there is an automatic air exhaust valve.
