1. 1. Identifying factors that correlate with Enhanced Biological Phosphorus Removal upsets at Lundåkraverket

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Rounak Niranjan; [2021]
   Keywords : Enhanced biological phosphorus removal; polyphosphate accumulating organisms; glycogen accumulating organisms; sludge content in aeration basin; nitrates in aeration basin; pH of incoming water; principal component analysis; pairwise correlations; inhibition factors;

   Abstract : The Enhanced Biological Phosphorus Removal (EBPR) process is characterized as the most sustainable process to remove phosphorus from wastewater albeit with high variability in performance efficiency. Thus, unpredictable upsets in the EBPR system is the norm across several wastewater treatment plants throughout Sweden, forcing the hand of the operators to dose higher volume of chemicals to reach the effluent requirements.
