1. 1. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Sara Rosendahl; [2021]
   Keywords : Wastewater treatment plant; phosphorus precipitation; control strategy; feedforward; feedback; ASM2d and primary clarifier model.;

   Abstract : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. READ MORE

3. 2. Modeling of Käppala Waste Water Treatment Plant - Evaluation of the Influence of Storm water to the Treatment Process

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maberana Moses Bashide; [2015]
   Keywords : wastewater treatment; storm water; Käppala; modelling; WEST; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : The Käppala WWTP data is modelled by using WEST software to evaluate how the storm water affects the treatment plant process and to use the flow data from Ryaverket WWTP to the Käppala WWTP model in order to model. The flow estimation method which gives best results for the flow data over a long period on the low flow occurrence is 95 percentile flow estimation method. READ MORE

4. 3. Evaluation of Biological Hydrolysis Pre-treatment and the Biogas Potential of Sludge from Compact Waste Water Treatment

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Lina Falk; [2015]
   Keywords : biological sludge hydrolysis; biogas; biochemical methane potential tests; compact waste water treatment; drum filter; anaerobic digestion; microfiltration; environmental engineering; water engineering; avloppsteknik; vattenförsörjningsteknik; Chemistry;

   Abstract : Med anledning av de ökande utsläppskraven för avloppsreningsverk kommer ökade resurser i form av elektricitet och kemikalier att krävas om dagens teknologi ska användas även i fortsättningen. Följaktligen undersöks för tillfället mer effektiva metoder, vilka tillåter inte bara rening av avloppsvattnet utan även erbjuder en möjlighet att ta tillvara på de resurser som finns i avloppsvattnet.

5. 4. Modelling Chemically Enhanced Primary Settlers Treating Wastewater using Particle Settling Velocity Distribution : Modellering av kemfällning i försedimentering för avloppsvatten, genom att använda distribuering av sedimentationshastigheter för suspenderadepartiklar.

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Emma Lundin; [2014]
   Keywords : Modelling; Primary clarifier; Chemically enhanced clarification; Settling velocity; MATLAB Simulink; Total suspended solids; Wastewater; Resource recovery;

   Abstract : The urban sprawl creates a gap between producers and consumers and the a sustainable circuitof nutrients and energy is difficult to maintain. Many times the waste that is created in urbanareas is not reused and the circuit is lost. 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
