How does a carbon filter work?
A carbon filter consists 3 main components: 1) a composite pressure vessel 2) a carbon filter control valve (usually low voltage) 3) carbon media The water filters down through the carbon filter media, up through a riser tube in the centre of the composite pressure vessel and out through the carbon filter control valve to service. Periodically, the carbon filter will backwash, which changes the water flow through the carbon filter. The water in the backwash cycle flows in from the inlet, down the centre riser tube, up through the carbon bed and out of the control valve to drain. The next step in a carbon filter regeneration cycle is rinse. The water in a rinse cycle of a carbon filter flows as in service, down through the composite pressure vessel and carbon filter media, up through the centre riser tube, through the carbon filter control valve and to drain. The carbon filter then returns to its normal service position. Please note that the above relates only to the smaller simplex car
