摘要:
A passive flow control valve including a barrier member adapted to attach to a fluid conduit. The barrier member defining an upper portion, a lower portion and an intermediate portion depending from the upper portion and the lower portion. The lower portion and the upper portion each defining an opening therein for allowing fluid to pass therethrough. The intermediate portion defining at least one orifice defined therein, wherein the orifice is configured to allow substantially controlled fluid flow therethrough. The flow control valve may also include a passive arrangement for collecting floatables discharged from a pipe.
摘要:
A wastewater source control system for use with a sewer service line conducting a flow of wastewater from a building to a sewer main. A flow control device is installed in the sewer service line with an upstream detention tank to detain building wastewater upstream from its point of discharge into a sewer main during certain heavy stormwater runoff periods.
摘要:
A method of influencing a flow of waste water in the waste water system of a housing development, in particular for reducing peak flows in these waste water systems. Reservoirs in the waste water system are activated in a surface-covering manner in order to delay discharge.
摘要:
A passive flow control valve including a barrier member positioned in a fluid conduit between an upstream conduit portion and a downstream conduit portion. The barrier member substantially prevents fluid flow around a barrier member perimeter. The passive flow control valve also includes barrier member orifices extending through the barrier member, which allow controlled fluid flow through the barrier member orifices. When the fluid flows through the upstream conduit portion and encounters the barrier member, the fluid is prevented from passing around the barrier member perimeter and is forced to flow through the barrier member orifices.

摘要:
A wastewater control system for use with a sewer service line conducting a flow of wastewater from a building to a sewer main. A flow control device is installed in the sewer service line; and an actuator, in electrical communication with the sensor, is connected to the flow control device. The actuator in response to an output signal from a hydrologic sensor causes the flow control device to block the flow of wastewater to the sewer main and detain the wastewater in the sewer service line.
摘要:
A flume for diurnally storing and releasing municipal sewage in its conveyance network of sewers and interceptor piping to reduce peak flow rates in a sewer system and the downstream wastewater treatment plant. The disclosed invention reduces peak flow rates without affecting flow rates below a selected threshold, maintaining minimum flow rates while storing wastewater in sewers and providing features that protect against sewer backups during high flows.
摘要:
The invention concerns a device for temporary storage of waste and rain water supplied to a pipe network. The device provides that at least the first part of the large quantities of water flowing into the pipes at temporarily occurring peak loads of the pipe network and thereby constituting a flow exceeding a predetermined basic or normal flow for the pipe network or parts thereof, is temporarily stored in one or more places in at least the upstream located pipes of the network. The water temporarily stored in this way is then permitted to run off successively as the supply of the large quantities of water diminishes or ceases. The device of the invention comprises a flow regulator which is arranged to limit an upstream space of the pipe for the temporary storage of water when the flow exceeds a predetermined basic flow.
摘要:
A multiple inlet flow regulator with a restricted low-level inlet and upper-level overflow inlet is used to modify a new or existing storm water catch basin to regulate the flow of storm water from the catch basin into the sewer system. During periods of heavy rains and high flows into the catch basin, this flow regulator will allow the catch basin to serve as a temporary storage tank for storm water. The construction of these flow regulators can be accomplished using a variety of off-the-shelf components or custom fabrication, to achieve the desired effect of restricting the discharge from each catch basin in a combined sewer or storm water system as much as practicable without resulting in overflows onto the roadways. Key components include: restricted low level inlet that can be adapted in size to meet specific low flow conditions, upper level inlet sized to allow for the maximum discharge from the catch basin to prevent overflows onto the roadway, connections to the existing catch basin structure and covers to prevent floatable debris from discharging from the catch basin into the sewer system.
