A system and process for the treatment of wastewater in a series of sequencing batch reactor basins wherein wastewater is sequentially fed, treated and discharged on a continuous basis.

System and process for the treatment of wastewater

A process strategy for the treatment of wastewater in a sequencing batch reactor wherein wastewater in quantities above a preselected minimum amount is proportionally aerated so as to reduce energy usage and operating costs.

Method for the treatment of wastewater

A piping and flow control system for a wastewater reactor having a reaction vessel includes an influent distribution and sludge withdrawal conduit located near the bottom of the reactor, an aeration device located within the reactor, a treated effluent decanting system and an automatic control mechanism including a liquid level sensor. The influent distribution and sludge withdrawal conduit along with the aeration device are selectively flow connected with a pumping mechanism by a piping manifold which is also selectively connected to a source for influent wastewater to be treated by the reactor and sludge disposal. The pumping mechanism is located in a pump column within the vessel. The manifold includes a series of control valves which may be selectively opened or closed to allow a single pumping mechanism; to input wastewater near the bottom of the reactor; or to withdraw concentrated sludge from the bottom of the reactor and dispose of the sludge to another location; or to withdraw fluid from the reactor through the influent distribution and sludge withdrawal conduit during agitation of the reactor and to inject the fluid into the aeration device with or without new wastewater; or to draw fluid backwards through the aeration device so as to clean nozzles or outlets associated therewith and to return the fluid to the reactor.

Reactor piping with pump column

A piping and flow control system for a wastewater reactor having a reaction vessel includes an influent distribution and sludge withdrawl conduit located near the bottom of the reactor, and aeration device located within the reactor, a treated effluent decanting system and an automatic control mechanism including a liquid level sensor. The influent distribution and sludge withdrawl conduit along with the aeration device are selectively flow connected with a pumping mechanism by a piping manifold which is also selectively connected to a source for influent wastewater to be treated by the reactor and sludge disposal. The manifold includes a series of control valves which may be selectively opened or closed to allow a single pumping mechanism: to input wastewater near the bottom of the reactor; or to withdraw concentrated sludge from the bottom of the reactor and dispose of the sludge to another location; or to withdraw fluid from the reactor through the influent distribution and sludge withdrawal conduit during agitation of the reactor and to inject the fluid into the aeration device with or without new wastewater; or to draw fluid backwards through the aeration device so as to clean nozzles or outlets associated therewith and to return the fluid to the reactor. A control valve on the decanting apparatus allows treated fluid to be selectively withdrawn from the reactor by the decanting apparatus.

Reactor piping and flow control system

A decanting apparatus for a wastewater treatment reactor includes a clarified fluid receiver having fluid receiving ports therein, support structure for maintaining the fluid receiver at a desired level within the reactor and flap means selectively biased to occlude the ports of the receiver during mixing cycles so as to prevent entry of sludge into the receiver and to selectively allow entry of clarified fluid through the ports when the sludge is settled. When the valve is closed, biasing means urges the flap to reseal the ports of the receivers so that sludge does not enter the receiver during sludge mixing cycles within the reactor. The receiver support structure includes an articulated and flexible joint to connect the receiver to the wall of the reactor, yet allow the receiver to maintain a desired level relative to fluid in the reactor and further maintain the receiver at a desired depth beneath the surface of the liquid level within the reactor to prevent floating debris from entering the receiver.
