Abstract
A system for introducing a liquid disinfectant into treated wastewater comprising a source of liquid disinfectant, a sensor to detect one of flow or level of treated wastewater in a receiver from or in a wastewater treatment system, a selectively operable pump to transfer the liquid disinfectant from the source into the treated wastewater and a controller operatively connected to the pump to selectively activate the pump in response to sensed, increased flow or level of the treated wastewater in the receiver for said wastewater above a sensed, predetermined point.
Claims15
A system for introducing a liquid disinfectant into treated wastewater comprising:
- a receiver for treated wastewater;
- a container for liquid disinfectant;
- a pump to transfer liquid disinfectant from said container into treated wastewater in said receiver;
- a sensor to detect at least one of flow or level of treated wastewater in said treated wastewater in said receiver;
- and
- a controller operatively connected to said sensor and said pump to selectively activate said pump in response to sensed, increased flow or level of said treated wastewater in said receiver above a predetermined point.
An apparatus for treating wastewater with a liquid disinfectant comprising:
- a vessel for wastewater;
- an inlet conduit for introducing wastewater into said vessel;
- a first pump disposed in said vessel and having a pump discharge;
- a discharge conduit having an outlet and operatively connected to said pump discharge for discharging water from said vessel;
- a recirculation conduit operatively connected to said pump discharge for recycling a portion of the wastewater discharged from said first pump back into said vessel;
- a container for liquid disinfectant;
- a pump to transfer liquid disinfectant from said container into said inlet conduit;
- a sensor to detect at least one of flow or level of wastewater in said inlet conduit;
- a control system operatively connected to said sensor and said pump, said control system being adapted to selectively activate said pump in response to sensed, increased flow or level of treated wastewater above a predetermined point.
An apparatus for treating wastewater with a liquid disinfectant comprising:
- a receiver for treated wastewater;
- a container for liquid disinfectant;
- a sensor to detect at least one of flow or level of wastewater in said receiver;
- a source of fluid pressure connected to said container;
- an outlet conduit connected to said container, said outlet conduit including a solenoid valve for selectively opening and closing flow through said outlet conduit, said outlet conduit having an outlet end for introducing liquid disinfectant into said receiver;
- and
- a control system operatively connected to said sensor and said solenoid valve, said control system being adapted to selectively open said solenoid valve in response to sensed, increased flow or level of treated wastewater in said receiver above a predetermined point.
