Abstract

A mobile water treatment unit is provided with separation and filtration components secured to a trailer.

Claims (18)

1. A mobile water treatment system comprising:

a trailer;

an inlet to a gravitational separator said gravitational separator being mounted on the trailer, and having a separator outlet;

a filter mounted on the trailer and having a filter inlet in communication with the separator outlet;

said filter having a filter outlet;

wherein the gravitational separator has a side drain for the removal of floatable liquids, and a side or bottom access port for the removal of sediment and pumping waste water into the separator induces a vortexing flow in the waste water to dynamically settle solids from the water.

2. The mobile water treatment system of claim 1 further comprising a special treatment additive tank in communication with the gravitational separator.

3. The mobile water treatment system of claim 1 further comprising a second gravitational separator mounted to the trailer interposed between the separator outlet and the filter inlet.

4. The mobile water treatment system of claim 1 wherein the gravitational separator has a bottom ramped downward toward a sediment removal port.

5. The mobile water treatment system of claim 1 wherein the gravitational separator has walls made of HDPE.

6. The mobile water treatment system of claim 1 wherein the filter has walls made of HDPE.

7. The mobile water treatment system of claim 1 wherein the separator has a side wall with a drain opening near the height of the inlet.

8. The mobile water treatment system of claim 1 wherein the filter is a gravitational filter.

9. The mobile water treatment system of claim 1 wherein the filter is an upflow filter.

10. The mobile water treatment system of claim 1 wherein the trailer has a plurality of stabilizing legs.

11. The mobile water treatment system of claim 1 wherein the separator has a sight glass to show the level of non-aqueous phase liquids inside.

12. The mobile water treatment system of claim 1 wherein at least one of the separator and filter has a high water level sensor.

13. The mobile water treatment system of claim 1 wherein the separator has a sediment level sensor.
