Classification: CPC C  Y | IPC C

Claim 10:
11. The anaerobic waste digestion system of claim 1, wherein
the third phase particle separator includes a dissolved carbon air floatation (DCAF) separator, influent entering the DCAF separator includes influent slurry, effluent exiting the DCAF separator includes feedstock, and slurry exiting the DCAF separator includes particles having a particle size larger than the predetermined size suitable for digestion, the DCAF separator including:
at least one adjusting baffle disposed so as to cause the influent slurry to flow through the adjusting baffle, and adapted for adjusting cross-sectional flow area, so as to regulate a flow rate of the influent slurry,
the separation zone, the separation zone being disposed downstream of the adjusting baffle, wherein the particles having a particle size larger than the predetermined size suitable for digestion are separated from wastewater feedstock particles which are generally smaller than the predetermined size suitable for digestion,
at least one sludge hopper for removing the slurry particles larger than the predetermined size, which are sinking; and
a conveyor with at least one blade for removing the slurry particles larger than the predetermined size, which are floating, wherein the solid particles having a particle size larger than the predetermined size suitable for digestion are returned to the first phase particle separator.
