1. 1. Effects of recirculating water treatment sludge

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Sofia Mile; [2023]
   Keywords : Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

   Abstract : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. READ MORE

3. 2. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Sanna Sahlin; [2021]
   Keywords : Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

   Abstract : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. READ MORE

4. 3. Mainstream Deammonification process monitoring by bacterial activity tests

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Andrea Carranza Muñoz; [2020]
   Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

   Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

5. 4. Ozonation of pharmaceutical residues in a wastewater treatment plant : Modeling the ozone demand based on a multivariate analysis of influential parameters

   University essay from Linköpings universitet/Teknisk biologi

   Author : Erica Engberg; Emilia Johansson; [2018]
   Keywords : ;

   Abstract : Most pharmaceutical residues in wastewater treatment plants (WWTPs) end up in the hydrosphere where they cause negative effects on the aquatic life and might disrupt ecosystems. By implementing an ozonation step (treatment with ozone) in the wastewater treatment process, these pharmaceutical residues can be reduced. READ MORE

6. 5. Wastewater treatment with nanofiltration in pilot-scale

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Jane Quach; Safa al Basheer; [2018]
   Keywords : wastewater; nanofiltration; ultrafiltration; chemical precipitation; pilot-scale; chemical engineering; kemiteknik; Technology and Engineering;

   Abstract : During the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. READ MORE
