Abstract
A hydrodynamic separator for storm water includes weirs and a first plate within a housing to create a pretreatment area for the storm water. The separator further includes a hollow inner member for inducing rotational flow of water and having an outlet below the first plate which outlet is connected to a lower second plate. Solids further settle from the water in the housing below the lower second plate. A water exit path exists between the two plates.

An assembly for the treatment of storm water, comprising:
- an outer housing having a hollow chamber with an upper portion, an opposed lower portion, a wall therein between, an inlet through the wall for the ingress of storm water, and an outlet through the wall for the egress of water;
- a hydrodynamic separator disposed configured to be disposed within the hollow chamber, the hydrodynamic separator comprising:
- a hollow inner tubular member having an open upper end, an opposed open lower end, a tubular wall disposed therein between, and at least one hole through the tubular wall configured for entry of storm water, the lower end having a first diameter;
- a first plate disposed proximal to the lower end of the hollow inner tubular member, the first plate having a second diameter, wherein the second diameter is greater than the first diameter;
- a first lower weir spaced apart from a second lower weir, wherein the first and second lower weirs extend upward from the first plate;
- a first higher weir disposed proximal to the first lower weir, the first higher weir extending upward from the first plate and having a height greater than a height of the first lower weir;
- a second higher weir disposed proximal to the second lower weir, the second higher weir extending upward from the first plate and having a height greater than a height of the second lower weir;
- and
- a second plate disposed below the first plate, the second plate having a third diameter, wherein the first diameter is less than the third diameter and the third diameter is less than the second diameter;
- wherein the hydrodynamic separator is configured to allow ingress of storm water from a first location between the first lower weir and the second lower weir, the first location being defined by a first angular extent between the first and second lower weirs;
- wherein the first and second plates are configured to be disposed about the lower end of the hollow tubular member;
- and
- wherein the first plate has an opening configured to allow egress of storm water to a second location between the first higher weir and the second higher weir, wherein the second location is defined by a second angular extent opposed from the first angular extent.
