Candle filter are filter elements with the flowing qualities:
Small diameter usuall less than 1.97 in.(50mm)
Substantial length usually greater than 39.37 in.(1,000 mm)
Very fine openings:25 to 150 microns,according to the application.
Medium support(diatoms in filters)
The filtration capacity can be easily modified by varying the number of candle filters to obtain the required filter area.
A stronger flow in the backwash direction, known as backwash, cleans the candle filters effectively.
Because the filter elements are particularly rigid and rugged, they can be disassembled without risk of damage to the filter surface.
