1. 1. Bearbetningsmetoders påverkan på markorganismers aktivitet i jorden : i perenna odlingar samt i odlingssystem med mellangrödor

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

   Author : Jenny Olofsson; [2021]
   Keywords : markorganismer; respiration; organiskt material; odlingsmetoder; biologiska processer; kemiska processer och fysikaliska processer; perenna odlingssystem; mellangrödor; klimatförändringar; microbial activity; respiration; organic matter; soil tillage methods; biological processes; chemical processes and physical processes; perennial crops; conservation agriculture; intermediate crops; climate change;

   Abstract : Klimatförändringarna, som både påverkat och påverkar vår planet, kräver att mänskliga aktiviteter förändras till mer resurssnåla och systemeffektiva processer. I dessa processer bör markens bördighet vara det centrala, eftersom en bördig mark kan generera stabila skördar och bidra till en långsiktigt hållbar matförsörjning. READ MORE

   Keywords : sludge dewatering; sewage sludge; laboratory scale sludge treatment; dewatering sludge; dewatering sewage sludge; CST; capillary suction time test; centrifuge; lab-centrifuge; rheology; polymers conditioning; sludge conditioning; centrifuge on lab scale; evaluation of lab experiments; CST evaluation; mechanical de-watering evaluation; sludge dewatering at lab; lab scale dewatering process; sludge dewatering methods at lab; Chemical engineering; Lab centrifuge; Capillary Suction Time CST ; Mechanical sludge dewatering evaluation; Polymers conditioning of sludge; sewage sludge dewatering; methods for sludge dewatering at lab; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

   Abstract : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. READ MORE

4. 3. Systematic Assessment of Straw as Potential Biogas Substrate in Co-digestion with Manure

   University essay from Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

   Keywords : Biogas; substrate; straw; systematic assessment; renewable energy; biofertilizer; anaerobic digestion; Biogas; biogassubstrat; halm; systematisk utvärdering; förnybar energi; biogödsel; rötning;

   Abstract : This work was carried out at Biogas Research Center (BRC) and the company Biogas in Vadstena. The aim was to systematically evaluate new substrates for biogas production. In particular, this case investigated the potential of straw in co-digestion with manure and slurry from pig, chicken and dairy. READ MORE

5. 4. Blackwater sanitization with urea in Sweden : sanitization effect and environmental impact

   University essay from SLU/Dept. of Energy and Technology

   Author : Brenda Vidal Estévez; [2014]
   Keywords : blackwater; ecological sanitation; fertilizers; urea treatment; system assessment;

   Abstract : The increasing global population is placing pressure on the water resources and nutrients needed for food production, while increasing the amount of waste generated and the environmental contamination. Technical solutions and changes in the social perception of the environmental problems are needed to address these problems. READ MORE

6. 5. Descriptive Assessment and Amendment of the SimpleTreat Model - Modelling of Organic Chemicals in Sludge for Soil Applications

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Belinda Chieng; [2012]
   Keywords : SimpleTreat; organic compounds; REVAQ; soil amendment; methodology; WWTP; fugacity and steady-state model; Technology and Engineering;

   Abstract : Large quantities and numbers of organic compounds (OCs) from industries and domestic sources enter the wastewater treatment plants (WWTPs) everyday, which is an ever-increasing issue in modern society. In WWTPs, the pollutants are either degraded or emitted to the air, the effluent (water) or the sludge (biosolids). READ MORE
