DISCUSSION
The combination of Binot and Vion:
Claims 18-20 stand rejected under 35 USC §103(a) as being
unpatentable over the combination of Binot and Vion. Claims 19-20 depend
directly or indirectly from claim 18. Claim 18 is drawn to a method of degreasing
water or wastewater in the course of treating water or wastewater. As we
understand it, the method comprises three steps, wherein the water or
wastewater is:
- subjected to treatment by flocs ballasted by granular material,
- directed through coagulation, flocculation and sediment devices, and
- degreased within the coagulation, flocculation and sediment devices.
