Stage 1:	Warm effluent enters the pipe and is cooled to ground temperature.
Stage 2:	Suspended solids separate from the cooled liquid effluent.
Stage 3:	Skimmers further capture grease and suspended solids from the exiting effluent.
Stage 4:	Pipe ridges allow the effluent to flow uninterrupted around the circumference of the pipe and aid in cooling.
Stage 5:	A mat of random, coarse fibers separates more suspended solids from the effluent.
Stage 6:	Effluent passes into the geo-textile fabric and grows a protected bacterial surface.
Stage 7:	Sand wicks liquid from the geo-textile fabric and enables air to transfer to the bacterial surface.
Stage 8:	The fabric and fibers provide a large bacterial surface to break down solids.
Stage 9:	An ample air supply and fluctuating liquid levels increase bacterial efficiency.
