Abstract:

This paper presents result of aquaculture wastewater treatment efficiency assessment by recirculating model Biofloc Technology (BFT). In 150 days experiment process, the studying was conducted a survey and assessment of water quality parameters such as NH4+, NO2- and NO3-. The data analysing results showed the decreasing trends of pollutant concentrations follow time series. The concentrations of NO2- and NO3- were determined 0.0882 (SD = 0.0740) and 1.7559 (SD = 0.6795) mg/l, respectively. The NO2- and NO3- parameters steady-state had high values, which were equal to 89.8% (SD = 6.5) and 35.6% (SD = 11.3). The level of NH4+ was varied from 0.0196 to 2.355 mg/l and averaged 0.4833 (SD = 0.5701) mg/l. The treatment efficiency of NH4+ was ranged between 16.3% and 84.8%, and averaged 51.5% (SD = 28.3). Therefore, this shows that biofloc technology promises saving potential and contributes to water resources sustainable protection in aquaculture activities.
