ELSEVIER Ecological Engineering 5 (1995) 371-390 ECOLOGICAL ENGINEERING Use of aquatic and terrestrial plants for removing phosphorus from dairy wastewaters Thomas A. DeBusk a,*, James E. Peterson a, K. Ramesh Reddy aAzurea, Inc., Box 561178, Rockledge, FL 32956-1178, USA b Department of Soil and Water Science, Unicersity of Florida, GainesL,ille, Florida, USA Abstract A microcosm study was conducted in Okeechobee, County, Florida, to evaluate the P removal potential of several aquatic macrophytes and "unconventional" terrestrial crops cultured on dairy lagoon wastewaters. Existing conventional spray field crops in this region that are irrigated with dairy wastewaters are estimated to remove 23 mgP/m-'-day. Effects of season and hydraulic retention time (HRT) on P uptake by the floating macrophytes water hyacinth (Eichhornia crassipes) and duckweed (Lemna obscura) were evaluated using half-strength primary lagoon effluent as a growth medium. Maximum P uptake rates by water hyacinths in February and July were 59 and 200 mgP/m2-day, respectively, whereas P uptake by duckweed was identical (20 mgP/m2-day) during both periods.
