Abstract: (2278 Views)

In this study, the bioremediation of shrimp ponds wastewater using Gracilaria corticata and Artemia franciscana was studied in Kuhstak region. The study contained three treatments (1) Gracilaria algae (2), Gracilaria and Artemia algae, and (3) Artemia, each with three replicaes for 72 hours. The results showed no significant differences among treatments in terms of physicochemical factors (P> 0.05). In terms of ammonium and nitrate, the treatments were significantly different (P <0.05); and treatment 2 showed the best efficacy of ammonium and nitrate removal at the end of the experiment (30% and 72.19%, respectively). In terms of nitrite, treatment 3 showed a significant difference compared to and treatment s1 and 2 (P <0.05). at the end of the experiment, all three treatments almost succeeded in removing nitrite from the environment, although the efficiency of treatment 1 and 2 (7.96%) was much higher compared to treatment 3 (96.3%). Phosphate was significantly increased in treatments 2 and 3 (P <0.05). In general, the use of these organisms as biological filters has the potential to perform a correct environmental action and can help to improve the water quality of coastal areas.
