    Keywords : Phosphorus removal; Chemical precipitation; Magnesium chloride; Calcium chloride; Struvite; Calcium phosphate; Parameters; Recovery;

    Abstract : The report formulates the experiments conducted to remove phosphorus from the return sludge wastewater subjected to side-stream hydrolysis. The experiments are conducted using the wastewater from the outlet of side-stream hydrolysis and is tested in a laboratory at the Duvbackens wastewater treatment plant in Gävle. READ MORE

  4. 23. Recirculation of phosphorus : an optimization analysis of processes to recycle phosphorus from sewage sludge

    University essay from SLU/Dept. of Economics

    Author : Linnéa Sellberg; [2016]
    Keywords : cost minimisation; fertilizer; phosphorus; recycling; recirculation; sewage sludge; wastewater treatment;

    Abstract : Phosphorus is a limited resource and for countries like Sweden without domestic mines, it becomes increasingly important to recycle this resource. Sewage sludge is rich in phosphorus and has traditionally been used as a fertiliser via direct application to farmland. READ MORE

  5. 24. Analyzing the process of struvite recovery with life cycle assessment : a case study

    University essay from SLU/Dept. of Energy and Technology

    Author : Attila Némethy; [2016]
    Keywords : phosphorus; crystallization; sewage sludge; nutrient recycling; impacts; fertilizer;

    Abstract : In this study a comparative life cycle assessment was conducted, where a wastewater treatment method with a newly integrated struvite precipitation process was analyzed and compared with the conventional enhanced biological nutrient removal (EBNR) - based wastewater and sludge treatment. A case study was carried out based on data from a wastewater treatment plant in south Sweden, which was operating with EBNR, and started to use integrated struvite precipitation on pilot-scale in 2013.
