1. 1. Fouling modelling in a UHT unit based on plant data.

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Thai Lam; [2023]
   Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE

3. 2. Theoretical and Experimental Characterizationof a Soft Polymer Heat Exchanger forWastewater Heat Recovery

   University essay from KTH/Energiteknik

   Author : Sixiang Lyu; [2020]
   Keywords : polymer heat exchanger; wastewater; heat recovery; heat transfer enhancement; oscillation i; polymervärmeväxlare; avloppsvatten; värmeåtervinning; förbättring av värmeöverföring; svängning;

   Abstract : Wastewater released from showers, sinks, and washers contains a considerable amount of wasteheat that can be recovered by using a heat exchanger. Conventional metal heat exchangers for wastewater heat recovery have common problems of corrosion, fouling and clogging, which makes it necessary to develop a new type of heat exchanger for such low-grade thermalenergy recovery applications.

4. 3. Fouling Dependency of Air in Dairy Processing

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Erik Lorin; [2018]
   Keywords : Fouling; Dairy; UHT; Bubble; Bubble induced fouling; Drying; THE; Dairy Processing; Processing; Bubble Nucleation; Differential Pressure; Oxygen sensors; chemical engineering; kemiteknik; Agriculture and Food Sciences; Chemistry; Technology and Engineering;

   Abstract : In this master thesis project, the formation of fouling on heat exchanger surfaces in dairy processing and mainly the influence of air was examined. Based on prior experimental findings regarding the influence of air bubbles in combination with calculations based on solubility properties of air in milk, a hypothesis was stated. READ MORE

5. 4. Testing the Heat Transfer of a Drain Water Heat Recovery Heat Exchanger

   University essay from KTH/Energiteknik

   Author : Emma Grundén; Max Grischek; [2016]
   Keywords : ;

   Abstract : This study investigates the change in thermal resistance due to fouling in drain water pipes. As insulation of houses and energy efficiency of appliances improve, the importance of Drain Water Heat Recovery (DWHR) is growing steadily. READ MORE

6. 5. Biofouling on plate heat exchangers and the impact of advanced oxidizing technology and ultrasound

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Anna Hjalmars; [2014]
   Keywords : Ultrasound; Biofilm; AOT; Plate Heat Exchangers and Crystal Violet;

   Abstract : Fouling in general and biofouling in specific is a problem concerning many industries. Biofouling occur in environments favorable for biological growth. As an example, industries using cooling water have problems with biofouling. The problem is apparent on heat exchangers as biofilm reduces the heat transfer and thus the performance. READ MORE
