<p>The invention provides a filter cartridge for the treatment of water which comprises an inlet for the water to be treated, the inlet communicating with a downwardly extending hollow passage (TP) adapted for gravity flow of water there through, the hollow (TP) passage being connected at its lower end to at least one filter media, and an outlet for exiting treated water from the filter media; whereby water flows through the hollow passage (TP) and enters the lowermost end of the filter media (FCC) to travel upwards through the filter media so that entrapped air in the filter media may be released upwards and out of the filter cartridge during the passage of water through the filter media in the upward direction. The flow of water in the upward direction facilitates the release of entrapped air in the system of the invention. This provides for controlled uniform flow of water through the filter cartridge, which generates quality water even after extensive use.</p> |
