Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

THE INVENTION CLAIMED IS

1. A clarifier for water treatment comprising:

a plurality of planar inclined sheets comprising a flexible polymeric material, wherein each sheet comprises a hydrophobic surface.

2. The clarifier of claim 1, wherein the flexible polymeric material comprises polyester, polyethylene, polypropylene, polytetrafluoroethylene (PTFE), and/or polyvinyl chloride (PVC).

3. The clarifier of claim 1, wherein the flexible polymeric material is a hydrophobic material.

4. The clarifier of claim 1, wherein a surface of the flexible polymeric material is a fabric treated with a hydrophobic material to form the hydrophobic surface.

5. The clarifier of claim 1, wherein the hydrophobic surface has an average surface roughness (Sa) of from 3 to 100 μπι.

6. The clarifier of claim 1, further comprising a plurality of vertically-oriented supports, wherein a sheet of the plurality of planar inclined sheets is tensioned between the plurality of vertically-oriented supports.

7. The clarifier of claim 6, wherein a vertically-oriented support of the plurality of vertically-oriented supports comprises an inlet opening configured to allow liquid to flow therethrough.

8. The clarifier of claim 1, wherein the plurality of planar inclined sheets are arranged parallel to one another, and each sheet of the plurality of planar inclined sheets is tensioned between a plurality of vertically-oriented supports.

9. The clarifier of claim 8, wherein vertically-oriented supports tensioning a first sheet of the plurality of planar inclined sheets interlock with adjacent vertically-oriented supports tensioning a second sheet of the plurality of planar inclined sheets.

10. The clarifier of claim 8, wherein the parallel sheets are positioned at an angle relative to the ground of from 10° to 90°.

11. A water treatment system comprising:

a basin; and

the clarifier according to claim 1 positioned in the basin, the clarifier further comprising a plurality of vertically-oriented supports, wherein each sheet of the plurality of planar inclined sheets is tensioned between the plurality of vertically-oriented supports.

12. The water treatment system of claim 11, wherein the flexible polymeric material comprises polyester, polyethylene, polypropylene, polytetrafluoroethylene (PTFE), and/or polyvinyl chloride (PVC).

13. The water treatment system of claim 11, wherein the hydrophobic surface has an average surface roughness (Sa) of from 3 to 100 μιη.

14. The water treatment system of claim 11 , wherein the plurality of planar inclined sheets are arranged parallel to one another.

15. The water treatment system of claim 14, wherein vertically-oriented supports tensioning a first sheet of the plurality of planar inclined sheets interlock with adjacent vertically-oriented supports tensioning a second sheet of the plurality of planar inclined sheets.

16. The water treatment system of claim 14, wherein the parallel sheets are positioned at an angle relative to the ground of from 10° to 90°.

17. The water treatment system of claim 11, further comprising a collection system comprising a collection trough arranged at least partially above the clarifier.

18. The water treatment system of claim 17, wherein the collection system comprises a buoyant member configured to support the collection trough.

19. A method for treating water comprising:

providing the clarifier according to claim I;

flowing water to the clarifier;

collecting clarified water and/or waste material separated from the water by the clarifier.

20. The method of claim 19, wherein the flexible polymeric material comprises polyester, polyethylene, polypropylene, polytetrafluoroethylene (PTFE), and/or polyvinyl chloride (PVC).
