Popis: Phosphorus as a fundamental element for growth and metabolism of living organisms, yet problematic to water quality, is an irreplaceable component. Application of enhanced biological phosphorus removal (EBPR) technology in wastewater treatment plants offers phosphorus removal and recovery in addition to potential eutrophication prevention. This process is dependable on enrichment of phosphorus accumulating organisms in activated sludge to accumulate great amount of poly-phosphate inside their cell interior for enhancement of phosphorus removal. Yet, inadequate removal performance in pilot and full-scale systems, rises the need for optimization in operation and design of applicable configuration. In addition to applying advancement strategies to minimize the growth of undesirable microorganisms through cost effective phosphorus removal along with potential P-recovery and sustainability. Preceding research has certainly advanced the insight on this area of investigation. Notwithstanding, there are still numerous unresolved issues to be undertaken. This comprehensive review paper aims to revisit the current knowledge and fundamental understanding on microbiology and biochemical transformations in EBPR process. In view of application and structure, EBPR design and operation considerations along with process configurations is critically reviewed. This comprehensive review hopes to touch on the critical points of operation to help in understanding the overall EBPR process and to farther provide insights on future work onto EBPR process developments.
