Media Filters

Media  Filters are  more   substantial  in  design than  cartridge  filters and apart from the media enclosed, are all similar in construction.

The media is enclosed in a  pressure  vessel  of steel or glassreinforced plastic fibre construction with inlet and  outlet nozzles. Each media vessel is complete with all frontal pipework and valves, to allow the filter to  be backwashed  and rinsed when necessary.

An  internal  distribution system, with upper and lower distributors, ensures an even flow through the  media  bed.  The  media  bed  contains  the actual filtering medium, supported by a layer  of gravel.

The following type of filters are in common use:

Sand Filters                   - Removal of suspended  solids
Activated Carbon Filters  - Removal of chlorine and  odor  by absorption
Iron Removal Filters        - Removal of iron by oxidation and                                        filtration

Media filters could be supplied with manual or automatic   valves   depending   upon  Client's request.
