Phytotreatment of wastewater released from intensive culture of giant black tiger shrimp (Penaeus monodon) Using Impomoea aquatica Forsk., Neptunia oleracea Lour., AND Trapa bispinosa Roxb.)
Abstract:
The purpose of this study wa to investigate the efficiency of three economic aquatic plant : Ipomoea aquatica Neptunia oleracea and Trapa bispinosa for treatment of wastewater released from black tiger shrimp pond culture. Three aquatic plant were added at the density of 300 g in the experiment tank of 40 75 40 cm. congtaining 100 l for 28 days .The experiment was carried out with three replicated using the complately randomized design CRD .The result showed that T.bispinosa had the highest efficiency on removeal of wastewater. Removal efficiency of BOD, turbidity, ammonia, nitrite, nitrate and phosphate was 90%,91.7%,67.9%,53.2%,98% 70.5% respectively . T.bispinosa is the most efficient economic crop for remediation of wastewater released from black tiger shrimp pond. The next experiment was to investigate the efficiency of T.bispinosa for treatment of wastewater released from black tiger shrimp pond culture to reduce BOD, turbidity, ammonia,nitrite,nitrate and phosphate. Three portion of the aquatic plant T.bispinosa 200,300and 400 gram per tank were used to study in the experime nt tank with 100 L of shrimp-pond wastewater. The CRD were used to set up the experiment with 3 replicates within 35 days . The result showed that T.bispinosa with three differnt density and the control showed different efficincy in decreasing BOD ,turbidity, ammonia, nitrite ,nitrateand phosphate. T.bispinosa 400 g had the highest removal efficiency for BOD ,turbidity, ammonia, nitrite,nitrate and phosphate which were 93.67%,92.09%,84.43%,65.65%,59.56% 80.11% respectively.
