Cincinnati, Ohio)
ABSTRACT: A novel two-stage reciprocating wetland was
operated over a period of six months to treat wastewater
from a pilot-scale intensive tilapia aquaculture operation.
High strength wastewater was applied to the system at
BOD5 loading rates in excess of 500 lbs/acre/day. Removal
rates for BOD5, total nitrogen and total phosphorus
averaged 99, 95 and 84 percent respectively.
