A stormwater treatment device may include a crossflow settling device having a treatment channel defined by a front baffle, a rear baffle, and a pairs angled plates provided at supplementary angles therebetween and disposed between the front baffle and the rear baffle, the front baffle having a treatment channel opening and the rear baffle having a treatment channel outlet. Under normal flow, stormwater flows into the inlet and into the inlet chamber, into the treatment channel via the treatment channel opening, into the outlet chamber via the treatment channel outlet in a crossflow pattern causing the sediment to fall out of suspension, and out of the crossflow setting device through openings at the bottom of the pairs of angled plates.

Crossflow setting devices and methods of use

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.
