1. 1. Effect of biofilm thickness and carrier type on the performance of anaerobic moving bed biofilm reactors (AnMBBRs)

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Astrid Hermansson; [2020]
   Keywords : Anaerobic; wastewater treatment; AnMBBR; MBBR; biofilm thickness; carrier; organic removal; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

   Abstract : The anaerobic moving bed biofilm reactor (AnMBBR) is a wastewater treatment process that has shown effective for the treatment of industrial wastewaters. As the AnMBBR is a biofilm process, nutrients, products, etc. must be transported through the biofilm. The thickness of the biofilm may, therefore, impact the process. READ MORE

3. 2. The possibilities of recycling wash water at Vidinge

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Julia Mauritzson; [2020]
   Keywords : reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

   Abstract : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. READ MORE

4. 3. Yield of Bromate from Ozonated Wastewater and the Potential for Biological Reduction of Bromate in Wastewater in Sweden

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Lauren Dell; [2020]
   Keywords : biological reduction; bromate; ozonation; disinfection by-products; bromide; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : The impact that anthropogenic micropollutants have on the environment is increasingly gaining attention. As a result of this, Sweden, among other countries, is looking towards implementing advanced treatment for micropollutant and pharmaceutical product removal from wastewater prior to discharge into the environment.

5. 4. Monovalent selective electrodialysis in greenhouses - An analysis of brackish groundwater and greenhouse wastewater treatment

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Georg Schücking; [2020]
   Keywords : desalination; water treatment; greenhouses; ED; MSED; monovalent selective electrodialysis; groundwater; sodium; nitrate; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : Water use in greenhouse can be optimized by switching to alternative sources of irrigation water and building zero-liquid discharge systems that recirculate greenhouse effluent. The use of brackish groundwater (BGW) has become a popular option for greenhouses that have adopted reverse osmosis (RO) to reduce the salinity of their source water. READ MORE

6. 5. Pulse Electric Field as a Pre-treatment Method of Wastewater Sludge prior to Anaerobic Digestion

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Milton Matilde; [2020]
   Keywords : PEF; AD; biogas yield; sludge pre-treatment; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

   Abstract : This work analyzed the impact caused by different intensities of Pulsed Electric Fields (PEF) pre-treatment on the biogas production from small-scale anaerobic digesters of wastewater sludge under thermophilic conditions. PEF technology consists of passing the substrate through an electric field which generates a potential difference across the cells, resulting in electroporation. READ MORE
