Tilapia and Fish Wastewater Characterization and Regulatory Experiences in New York Dr. Michael B. Timmons Professor Department of Agricultural and Biological Engineering Cornell University Ithaca, NY 14850 USA Dr. Shulin Chen Associate Professor Biological Systems Engineering Washington State University Pullman, WA Introduction and Background This paper will report on our experiences with the water regulatory agencies governing wastewater treatment in NY State and provide some additional background information on waste and manure characteristics from tilapia and fish in general. At this point in time, we can not draw any definitive differences between tilapia manure and other fish species manures, see Figure 1 for a general mass balance. All fish in the process of assimilating feed will produce ammonia which in turn must be oxidized by the nitrification system used for the facility: Nitrosomonas (autotrophic) NH4 + 1.5 O2 --> 2H + H2O + NO2 Nitrobacter (autotrophic) NO2 + 0.5 O2 --> NO3 Alkalinity destruction (7 g per g NH4) Note that the ultimate fate of the protein-nitrogen in the above equations is nitrate (NO3). Chen et al. (1997) has summarized the waste generation for the major farm animals (see Table 1). In particular, the waste being produce from fish can be described as (Chen, et al. 1997): • TSS 20-50% • BOD 10-60% • Ammonia-N 3% (will become after nitrification nitrate-N) • P 1% 1
