Abstract
An apparatus for disinfecting flowing wastewater in a conduit with a liquid disinfectant from a reservoir of liquid disinfectant. A valve assembly is operatively connected to the liquid disinfectant source for selectively dispensing liquid disinfectant from the source. The valve has a movable valve element normally biased to the closed position. There is an actuator connected to the movable valve element which is responsive to at least one of flow or level of wastewater in the conduit to overcome the biasing force and allow the valve member to move the valve from the normally closed position to an open position.
