Abstract
An inline filterwell system with a floating weir that delivers a dispersant into the water in an inline filterwell where a cartridge dispenser dispersant rate of a cartridge dispenser located in a cartridge jacket of the weir is isolated from changes in the velocity of water flowing through an open body of the weir.
Claims21
An inline floating weir comprising:
- a cartridge jacket located in the inline floating weir, the cartridge jacket having a water inlet and a water outlet therein;
- a set of protuberances within the cartridge jacket;
- a cartridge located in the cartridge jacket, the set of protuberances supporting the cartridge in a spaced condition from an interior surface of the cartridge jacket thereby forming an annular water flow path between the interior surface of the cartridge jacket and an exterior surface of the cartridge;
- and
- a further cartridge jacket located in the said inline floating weir, the further cartridge jacket having a water inlet and a water outlet therein;
- a set of further protuberances within the said further cartridge jacket;
- a further cartridge located in the said further cartridge jacket, the set of further protuberances supporting the further cartridge in a spaced condition from an interior surface of the further cartridge jacket thereby forming a further annular water flow path between the interior surface of the further cartridge jacket and an exterior surface of the further cartridge;
- and
- a cartridge retainer comprising either:
- (i) a rotatable crossbar engaged with both a top end of the cartridge and a top end of the further cartridge to removably secure the cartridge and the further cartridge within the inline floating weir, or (ii) a lip of the cartridge jacket engaged with a ledge of the cartridge, where the lip of the cartridge jacket is part of a resilient latch configured to flex outward to allow axial insertion of the cartridge into the cartridge jacket and when unflexed returns to a cartridge engaging position securing the cartridge within the cartridge jacket, and a lip of the further cartridge jacket engaged with a ledge of the further cartridge, where the lip of the further cartridge jacket is part of a resilient latch configured to flex outward to allow axial insertion of the further cartridge into the further cartridge jacket and when unflexed returns to a cartridge engaging position securing the further cartridge within the further cartridge jacket.

- a further cartridge located in the further cartridge jacket, the set of further protuberances supporting the further cartridge in a spaced condition from an interior surface of the further cartridge jacket thereby forming a further annular water flow path between the interior surface of the further cartridge jacket and an exterior surface of the further cartridge;
- and
- a cartridge retainer securing the cartridge, or securing both the cartridge and the further cartridge, removably within the inline floating weir, the inline floating weir nested within a filterwell basket, the cartridge jacket including a lateral extension that engages a first guide slot in the filterwell basket, the further cartridge jacket including a lateral extension that engages a further guide slot in the filterwell basket, such that the inline floating weir is free to move up and down within the filterwell basket in response to water level changes within the inline floating weir.
