Abstract
A separator unit includes a tank defining an internal volume and having an inlet and an outlet. An insert separates the tank into an upper chamber and a lower chamber. The insert includes a weir at an upper side to define an intake area for receiving an influent liquid, a first opening in the intake area for delivering liquid down into the lower chamber and a second opening on an opposite side of the weir for delivering liquid from the lower chamber back up into the upper chamber. The separator may include one or more of the first opening being of arcuate shape, a perforated shroud extending downward from the insert within the lower chamber and/or an upflow pipe extending downward from the second opening into the lower chamber, a bottom of the upflow pipe covered, and a slot opening in a sidewall of the upflow pipe.
