BIOMASS DEVELOPMENT ASSESSMENT OF CHLORELLA VULGARIS ALGAE AND POTENTIAL FOR APPLICATION IN SHRIMP WASTEWATER TREATMENT

Application of algae technology for environmental treatment is a widely option for sustainable aquaculture production, especially in the treatment of shrimp wastewater. This study aims to assess the biomass development as well as influencing factors, and the ability to nutrients handle in shrimp wastewater of Chlorella Vulgaris in an experimental model of 120 L capacity. Initial results showed that 10% of algae initially gave algae biomass at 1.13883 ± 0.01893 g/l on day 15. The sample 15% was shortest on day 9 at 1.10667 ± 0.02363 g/l and the light conditions (LED) matched the growth of C.Vulgaris is red, brightness at 120 μmol/m2 /s (6400 lux). Initial results showed that 10% of algae initially gave algae biomass at 1.13883 ± 0.01893 g/l on 15th day, the sample 15% was shortest on day 9 at 1.10667 ± 0.02363 g/l and the light conditions (LED) matched the growth of C.Vulgaris is red, brightness at 120 μmol/m2 /s (6400 lux). The results of treatment after 10 days showed that treatment efficiency on total Phosphorus was 95.24%, remain COD was 78 mg/l (treatment efficiency 84.64%), the efficiency of treatment on NH4, NO3, and NO2 were 91.31%, 81.56%, and 82.97%, respectively
