undergoes physical screening through two automatic bar screens, then is
pumped to the highest plant elevation by submersible influent pumps.
It then flows through a grit and grease removal unit, then to one of two,
2.4 million-gallon oxidation ditches for biological treatment and ammonia
nitrogen removal. Ditch effluent flows to two circular clarifiers, then
to four tertiary sand filters. The final treatment stage is disinfection
with ultraviolet light before discharge to the South Fork New River. Solids are
processed by a 2-meter belt press and a Class A thermal drier, producing
an 88-92% dry product that is distributed to the public for use as fertilizer. III.
