| Abstract | ||
| As a result of dwindling water supplies, the wastewater disposal costs, and tougher discharge regulations that have reduced allowable contaminant levels in waste streams, highly efficient and eco-friendly wastewater treatment approaches is becoming highly significant. Alginate beads found play a key role in wastewater remediation. In this study, the removal efficiency of alginate microbeads (7.5 – 12.5µm diameter) for nitrite, nitrate, ammonia and phosphate from the outlet of a phytoremediated municipal wastewater was studies for 72 h at the treatment periods of ½, 1.0, 2.0, 4.0, 24, 48 and 72 h. Satisfying removal results was obtained as follow: 100% nitrite removal (after 24 h), 100% nitrate removal (after 48 h), 72.53% ammonia (after 72 h), 39.44 % for phosphorous after 48 h and declined to 32.90 % after 72 h. Also, a remarkable decline in concentrations of COD and BOD was detected indicating the improvement of the quality of the treated wastewater by alginate microbeads. The use of alginate microbeads for wastewater treatment is less expensive and ecofriendly bioremediation technique, that performing tertiary treatment with a remarkable removal efficiency of nitrate, nitrite, ammonia and phosphate. | ||
