This study focuses on the evaluation of the performance of Chlorella sp. in removing nutrient in aquaculture
wastewater and its correlation with the kinetic growth of Chlorella sp. The treatment was applied
with various Chlorella sp. inoculation dosage ranging from 0% to 60% (v/v) of wastewater. The optimum
inoculation dosage was recorded at 30% (v/v) with effluent concentration of ammonia and orthophosphate
recording at 0.012 mg L1 and 0.647 mg L1, respectively on Day 11. The optimum dosage for
bio-flocculation process was obtained at 30 mg L1 of Aspergillus niger with a harvesting efficiency of
97%. This type of development of phytoremediation with continuous bio-harvesting could promote the
use of sustainable green technology for effective wastewater treatment.
