摘要： A high pressure jetting system includes a recirculating unit connected to an isolated section of a water supply system which remains under system pressure. The recirculating unit includes a filter unit and a pump unit generating a circulating flow of water. A first pig launch and recovery apparatus couples a first hydrant to the recirculating unit and a second pig launch and recovery apparatus couples a second hydrant to the recirculating unit. A camera unit including a camera and drogue chute enters through the first apparatus and travels in a flushing flow direction to the second apparatus. The drogue chute is then removed from the camera. The camera then couples to a jetting unit having a jetting head and hose and re-enters through the second apparatus. The jetting unit emits a plurality of water jets to move in a counter-current flow direction and remove material from the water mains.

摘要： A recirculating/filtering/flushing system for cleaning a water main is provided, wherein the water main includes first and second access points. The system comprises at least one filter for filtering water in the water main; an inlet conduit coupled with the first access point and the at least one filter; an outlet conduit coupled with the second access point and the at least one filter; a bypass conduit coupled with the inlet conduit at a first location upstream of the at least one filter, and coupled with the outlet conduit at a second location downstream of the at least one filter; and a pumping device for flowing the water in the water main through the inlet conduit, through either the at least one filter or the bypass conduit, and through the outlet conduit.

摘要： A flushing system includes a recirculating unit having a pump, filter, and flow manifold. The manifold includes a first conduit delivering water to the filter utilizing the pump. A first valve divides the first conduit into first and second portions. A second conduit receives water from the filter. A second valve divides the second conduit into first and second portions. A first reverse conduit having a third valve couples the first portion of the first conduit with the second portion of the second conduit. A second reverse conduit having a fourth valve couples the second portion of the first conduit with the first portion of the second conduit. When the first and second valves are open and third and fourth valves are closed, water flows in a forward direction. When the first and second valves are closed and third and fourth valves are open, water flows in a reverse direction.

摘要： A closed conduit system for use in a water supply system includes a recirculating unit configured to connect to an isolated section between a first point and a second point of the water supply system. The recirculating unit includes a first filter unit defining a first closed circuit including the isolated section and adapted to perform a first treatment. A second filter unit defines a second closed circuit including the isolated section and is adapted to perform a second treatment. At least one pump is capable of generating a flow of water through the first and the second closed circuit, and a valve selectively controls flow through either the first or the second closed circuit.
