Abstract:
A water treatment apparatus comprising:a regenerable treatment medium (29);a regulator (59) provided with a hydraulically driven first monitoring mechanism (24) having a first disc (60), and a hydraulically driven second monitoring mechanism (25) having a second disc (61);a single volumeter means (23) for driving both monitoring mechanisms (24-25);said first disc (60) of said first monitoring mechanism functioning to control the total amount of water consumption within an operational cycle of said regenerable treatment medium (29) and further functioning to order the start of a regeneration cycle, wherein said operational cycle involves a forward rotation of said first disc (60) from a starting position to a position where said regeneration cycle is ordered;said second disc (61) of said second monitoring mechanism (25) functioning as a programming disc for controlling said regeneration cycle; andsaid first monitoring mechanism (24) being further provided with reset means (98) for providing a backwards rotation of said first disc (60) to said starting position each time said regeneration cycle is performed.
