Abstract:
1. A mobile water pollution trap for separating pollutants from a liquid, comprising: a chamber having an inlet, an outlet, a floor, a maximum liquid level when the liquid is flowing through the chamber at a predetermined maximum water flow rate, and an at-rest liquid level when none of the liquid is flowing into the chamber; a collection reservoir disposed in the chamber between the inlet and the outlet, wherein the collection reservoir has a bottom wall and a front wall, the front wall has a skimming edge disposed at the maximum liquid level to skim floating portions of the pollutants into the collection reservoir, and the front wall skimming edge is disposed above the at-rest liquid level and the bottom wall is disposed above the chamber floor to direct the liquid to flow under the collection reservoir in a longer flow route through the chamber and to prevent the liquid from flowing into the collection reservoir; one or more baffles disposed in the chamber between the inlet and the collection reservoir, wherein each of the baffles comprises a panel with apertures defined therein that permit some of the liquid and pollutants to pass therethrough, and wherein the baffles are configured and positioned in the chamber forming at least one gap through which the liquid may flow around the baffles to increase liquid residence time in the chamber to encourage settling of some of the pollutants; and a trap operating system including an input pump connected to the chamber inlet for drawing the liquid and the pollutants into the chamber, a pollution tank connected to the chamber for receiving the skimmed pollutants from the collection reservoir, and a liquid tank connected to the chamber outlet for receiving the pollutant-free liquid from the chamber.
