Twenty nine strains of photosynthetic purple nonsulfur bacteria were isolated from Kyonggi area in Korea. The isolated strains were identified as Rhodopseudomonas blastica, Rhodocyclus gelatinosus, Rhodocyclus tenuis, and Rhodopseudomonas rutila. The enhanced nutrients removal system for wastewater using phototrophic purple non-sulfur bacteria was developed. Experiments were performed into two Phases and the results were compared: the synthetic wastewater was tested for the removal efficiency of nutrients and organics during Phase 1 and the real wastewater during Phase2. Results showed that 97∼99% of organics were removed during Phase 1 and 96∼99% during Phase 2. Nutrients (nitrogen and phosphorus) were also removed efficiently: 85∼91% removal of T-N and 78∼92% removal of T-P were achieved for Phase 1, and 76∼89% removal of T-N and 73∼88% removal of T-P for Phase 2.
