Improvement of separation and dewatering of activated sludge by using enhanced biological removal process over chemical phosphorus precipitation
(2006) In Journal of Residuals Science and Technology 3(3). p.145-151- Abstract
- Samples from several WWTPs in Sweden, operating either with chemical precipitation of phosphorus, biological phosphorus removal or combination of the two, were analysed for separation and dewatering properties. The main parameters of interest were capillary suction time (CST), extracellular polymeric substances (EPS), metal ions concentration, filterability and compressibility of the sludge. Enhanced biological phosphorus removal (EBPR)-sludge is composed of compact flocs, while the chemical sludge contains higher colloids concentration in the liquid phase and retain water within the floc structure by stronger physical forces. These two phenomena reflected in the poorer filterability as well as compressibility of the chemical sludge in... (More)
