1. 1. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Hanna Gustavsson; [2021]
   Keywords : Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

   Abstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE

3. 2. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients

   University essay from SLU/Department of Biosystems and Technology (from 130101)

   Author : Kristina Weimers; [2020]
   Keywords : Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

   Abstract : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. READ MORE

4. 3. Renewable energy from wastewater grown microalgae - a concept for nutrient recycling and sustainable energy recovery

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Stina Lidén; [2015]
   Keywords : sustainable wastewater treatment; vattenförsörjningsteknik; avloppsteknik; renewable energy; nutrient reduction; nutrient recycling; microalgae; AnMBBR; biogas; Technology and Engineering;

   Abstract : Wastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. READ MORE

5. 4. Fate of pharmaceuticals and perfluoroalkyl substances during source separated wastewater treatment

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Alina Koch; [2015]
   Keywords : pharmaceuticals; PFASs; source separated systems; blackwater; latrine; anaerobic degradation; urea sanitation; fate;

   Abstract : In the past decade, water reuse and nutrient recycling of wastewater has gained more attention as sustainable water cycle management solutions, driven by the increasingly noticeable resource restrictions of the 21st century. One of these possible solutions is source separated treatment of latrine or blackwater for nutrient recovery. READ MORE
