Abstract 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.

1 Introduction Eutrophication, the overgrowth of algae and dead zones in coastal marine ecosystems (Conley et al. 2009), ammonia toxicity, nitrate accumulation and limited water resources, urge the need for a proper nutrient removal and management strategy to preserve water quality. Excessive amount of nutrients is problematic to living organism’s health which has negative impact on humans quality of life (James 1997). Phosphorus as a key nutrient for growth of microorganisms and a fundamental element for production of essential organic molecules such as adenosine triphosphate (ATP), in high concentrations, originates the adverse effects on living organism communities (Oehmen et al. 2007). This element promotes eutrophication due to its anthropogenic activity in aquatic ecosystems (Bunce et al. 2018). Significant sources of phosphorus enters freshwater from ag
