Abstract

A biofilter material for biofiltering a fluid is disclosed. This biofilter material comprises fragments of coconut mesocarp. A wastewater treatment system is also disclosed and comprises a filter bed and a water distribution system. The filter bed comprises fragments of coconut mesocarp as a biofilter material.

Claims (20)

1. A wastewater treatment system characterized in that it comprises:

a filter bed comprising a biofilter material comprising a mass of fragments of coconut mesocarp, the mesocarp comprising a mixture of parenchyma bound up to mesocarp fibers; and

a water system adapted to direct water to the biofilter bed to be treated.

2. The wastewater treatment system of claim 1 , characterized in that said filter bed comprises fragments of different grain sizes and has an isotropic size distribution.

3. The wastewater treatment system of claim 1 , characterized in that said filter bed comprises fragments of different grain sizes and has an anisotropic size distribution.

4. The wastewater treatment system of claim 1 , characterized in that said biofiltering material comprises an additional biofiltering material apart from the fragments of mesocarp.

5. The wastewater treatment system of claim 4 , characterized in that said additional biofiltering material is selected from the group consisting of peat, mineral filtering media and synthetic filtering media.

6. The wastewater treatment system of claim 5 , characterized in that the filter bed has an isotropic distribution of said biofilter material and said additional biofilter material.

7. The wastewater treatment system of claim 5 , characterized in that the filter bed has an anisotropic distribution of said biofilter material and said additional biofilter material.

8. The wastewater treatment system of claim 4 , characterized in that said biofiltering material comprises from 20% to 80% of said fragments of mesocarp.

9. The wastewater treatment system of claim 4 , characterized in that said biofiltering material comprises 50% of said fragments of mesocarp.

10. The wastewater treatment system of claim 4 , characterized in that said other biofiltering material is peat.

11. The wastewater treatment system of claim 10 , characterized in that a layer of said peat is topping a layer of said biofilter material.

12. The wastewater treatment system as defined in claim 4 , characterized in that said filter bed consists of a layer of said biofilter material covering natural soil for further treating the water.

13. The wastewater treatment system as defined in claim 1 , characterized in that said filter bed consists of a layer of said biofilter material covering natural soil for further treating the water.

14. The wastewater treatment system as defined in claim 1 , characterized in that it comprises:

a filter chamber containing said filter bed, said chamber having an inlet for receiving the water from the said water system; and an outlet for discharging a treated water; the water entering the housing flowing from the inlet to the outlet.

15. The wastewater treatment system as defined in claim 14 , characterized in that the inlet is located in an upper portion of the chamber above the filter bed of biofilter material and the outlet is located in a lower portion of the chamber below the filter bed.

16. Use of a bed of fragments of coconut mesocarp comprising a mixture of parenchyma bound-up to mesocarp fibers for biofiltering water.

17. Use as defined in claim 16 , wherein said water is wastewater.
