The invention relates to a separation device for removing objects from a water flow, comprising a separation screen and a channel which forms an inlet and an outlet for the separation screen, wherein, during operation, a head water having a head water level can be provided in the inlet upstream of the separation screen and a tail water having a tail water level can be provided in the outlet downstream of the separation screen, wherein the outlet comprises an outlet cross-section for the water flow. The separation device is characterised by a damming body, which can be adjusted via an actuator, for immersion into the outlet, said damming body being able to be adjusted at least between a first position and a second position, wherein the outlet cross-section is smaller in the first position and the outlet cross-section is larger in the second position, and comprising a control device, wherein the control device includes a first operating mode, in which the flow rate in the area of the separation screen is increased by bringing the damming body from the first position to the second position, wherein the control device includes a second operating mode, in which the flow rate in the area of the separation screen is changed by bringing the damming body from the second position to a third position, wherein the outlet cross-section in the third position is smaller or larger than in the second position, and wherein the control device is configured to automatically activate the first and/or the second operating mode. The invention also relates to a method for operating such a separation device.

A stormwater treatment device may include a chamber having a floor and a wall; an inlet formed in the wall that receives stormwater into an inlet side of the chamber; an outlet formed in the wall that discharges stormwater from an outlet side of the chamber; an enhanced settling device positioned in the outlet side of the chamber; a flow diverter plate in a lower portion of the chamber; and an outlet control diverter positioned proximate to the outlet. Stormwater is received by the inlet in a first flow direction, flows from the inlet side to the lower portion of the chamber in a second flow direction, flows through the enhanced settling device to an upper portion of the chamber in a third flow direction, flows through the outlet control diverter in fourth flow direction, and is discharged by the outlet in a fifth flow direction.

The embodiments of the present disclosure provide a system for removing particulates from liquid. The system may comprise a base, a tubular body extending upwardly from the base, a liquid quality device located above the base, a sump region located between the base and the liquid quality device, and a plurality of drag-inducing portions positioned in the sump region and projecting inwardly toward a central axis of the sump region. The tubular body may comprise an inlet and an outlet. The plurality of drag-inducing portions may comprise a first set of drag-inducing portions, a second set of drag-inducing portions, a third set of drag-inducing portions, and a fourth set of drag-inducing portions. The first, second, third, and fourth sets of drag-inducing portions may be positioned equidistant from each other and at a same height around a perimeter of the sump region.

An apparatus and methods for the separation of macroscopic solid body particles (SBPs) from a fluid stream contained in a conduit, such as a hose or pipe. The method involves utilizing a particle separator having a fluid inlet port connected to a fluid inlet conduit and a fluid outlet port connected to a fluid outlet conduit to change the direction (and optionally the velocity) of the fluid stream within a lumen of an enclosed vessel component of the particle separator sufficiently to permit SBPs to fall by gravity (and/or to descend due to inertia) into a removable receptacle within a bottom portion of the vessel component while directing the flow of cleansed fluid to the fluid outlet port of the particle separator.

Stormwater management systems, methods, and apparatus for containing and filtering runoff may be provided. In one implementation, a stormwater management crate for managing stormwater runoff may be provided. The stormwater management crate may include a top plate having a first plurality of support column attachments and one or more support column assemblies located below the top plate; the one or more support column assemblies being affixed to the top plate at the support column attachments. The stormwater management crate may further include a bottom plate having a second plurality of support column attachments located below the support column assemblies. Stormwater management crates may be arranged into an array and include side panels of variable heights. The array of stormwater management crates may be further wrapped in sediment impervious material and serve to restrict stormwater flow as part of a stormwater management system.
