Abstract

A waste water and hazardous chemical containment and collection system includes a substantially planar, non-porous lower layer. A lower corrugated plate layer rests upon the planar, non-porous lower layer and an upper corrugated plate layer rests upon the lower corrugated plate layer. An upper layer that has several holes for the passage of fluids rests upon the upper corrugated plate layer. The overall length and width of the lower corrugated plate layer, the upper corrugated plate layer, and the upper layer are substantially equal. Fluids enter the system through the holes and some oils from the fluids collect within netting of the lower corrugated plate layer and the upper corrugated plate layer for later collection.

Claims (21)

1. A waste water and hazardous chemical containment and collection system comprising:

a substantially planar, lower layer, the planar, lower layer being non-porous except for a drain;

a lower plate layer resting upon the planar lower layer, the lower plate layer comprising geo-membranes arranged in a grid;

an upper plate layer resting upon the lower plate layer, the upper plate layer comprising the geo-membranes such that the grid of the upper plate layer is offset at an angle with respect to the grid of the lower plate layer; and

an upper layer having a plurality of holes for the passage of fluids;

wherein the overall length and width of the lower plate layer, the upper plate layer, and the upper layer are substantially equal;

the lower plate layer and the upper plate layer are configured such that the fluids enter the waste water and hazardous chemical containment and collection system through the plurality of holes, the fluids traverse the grid of the lower plate layer and the grid of the upper plate layer flowing towards the drain and as the fluids traverse the grid of the lower plate layer and the grid of the upper plate layer some oils from the fluids collect within the grid of the lower plate layer and the grid of the upper plate layer.

2. The waste water and hazardous chemical containment and collection system of claim 1 , in which the fluids comprise water with pollutants and oils that enters through the plurality of holes in the upper layer, at least some of the oils are trapped in the upper and lower plate layers and the water, pollutants and remaining oils exit through the drain.

3. The waste water and hazardous chemical containment and collection system of claim 2 , further comprising a separation tank fluidly connected to the drain, the separation tank further removing some of the pollutants and some of the remaining oils that have higher or lower specific gravities than the water through a weir system.

4. The waste water and hazardous chemical containment and collection system of claim 1 , further comprising walls surrounding the lower plate layer, the upper plate layer and the upper layer.

5. The waste water and hazardous chemical containment and collection system of claim 1 , wherein the lower plate layer and the upper plate layer are textured geo-membranes made by co-extruding textured, high density polyethylene.

6. The waste water and hazardous chemical containment and collection system of claim 1 , wherein the substantially planar lower layer is a layer of reinforced polypropylene.

7. A waste water and hazardous chemical containment and collection system comprising:

a substantially planar, lower layer, the planar lower layer being non-porous except for a drain;

a lower plate layer resting upon the planar lower layer, the lower plate layer comprising geo-membranes arranged in a grid;

an upper plate layer resting upon the lower plate layer, the upper plate layer comprising the geo-membranes such that the grid of the upper plate layer is offset at an angle with respect to the grid of the lower plate layer;

an upper layer having a plurality of holes for the passage of fluids; and

walls surrounding the lower plate layer, the upper plate layer, and the upper layer.

8. The waste water and hazardous chemical containment and collection system of claim 7 , wherein the lower plate layer and the upper plate layer are textured geo-membranes made by co-extruding textured, high density polyethylene.

9. The waste water and hazardous chemical containment and collection system of claim 7 , wherein the substantially planar lower layer is a layer of reinforced polypropylene.

10. The waste water and hazardous chemical containment and collection system of claim 7 , further comprising a separation tank that receives a water, remaining oils, and pollutants from the drain and further removes some of the pollutants and some of the remaining oils that have higher or lower specific gravities than the water through a weir system.
