Abstract

A particulate reusable sorbing coalescing agent facilitating the separation of a non-aqueous phase from an aqueous phase. The agent has a desired shape and properties, sheared from a block of matrix material and presents a higher coalescing rate relative to existing sorbing coalescing agents. Also, a method of manufacturing the particulate reusable sorbing coalescing agent and a method of use the particulate reusable sorbing coalescing agent are disclosed.

Claims (8)

1. A reusable sorbing coalescing agent for facilitating the separation of a non-aqueous phase from an aqueous phase consisting of a ragged-edge particulate reusable material having substantially small uniform sized particulate units, wherein the particulate reusable material includes particulate units of a size ranging from 1 μm to 3 cm and which comprise a ragged edge component having a dimension in the nanoscale range, and wherein said ragged edge component comprises outwardly extending filaments.

2. The sorbing coalescing agent according to claim 1 , wherein the particulate reusable material includes particulate units of a size ranging from 10 μm to 2000 μm.

3. A reusable sorbing coalescing agent for facilitating the separation of a non-aqueous phase from an aqueous phase consisting of a ragged-edge particulate reusable material having substantially small uniform sized particulate units, wherein the particulate reusable material includes particulate units of a size ranging from 1 μm to 3 cm and which comprise a ragged edge component having a dimension in the nanoscale range, wherein said ragged edge component comprises outwardly extending filaments and wherein the dimension in the nanoscale range is selected from the group consisting of ragged edge component thickness, ragged edge component filament size, and combinations thereof.

4. The sorbing coalescing agent according to claim 2 , wherein the dimension in the nanoscale range is selected from the group consisting of ragged edge component thickness ragged edge component filament size, and combinations thereof.

5. The sorbing coalescing agent according to claim 2 , wherein the particulate reusable material includes particulate units of a size ranging from 10 μm to 1000 μm.

6. The sorbing coalescing agent according to claim 4 , wherein the particulate reusable material includes particulate units of a size ranging from 10 μm to 1000 μm.

7. The sorbing coalescing agent according to claim 6 wherein the particulate reusable material is an organophilic hydrophobic sorbing coalescing agent capable of being electrostatically charged.

8. The sorbing coalescing agent according to claim 3 , wherein the particulate reusable material includes particulate units of a size ranging from 10 μm to 2000 μm.
