@masterthesis{Hermannsdoerfer, type = {Bachelor Thesis}, author = {Hermannsd{\"o}rfer, Frederic}, title = {Mechanical Preparation of External Thermal Insulation Composite Systems}, school = {Hochschule Rhein-Waal}, abstract = {The building industry relies heavily on energy conservation, energy efficiency, and resource efficiency. Thermal insulation composite systems (TICS) have been used to insulate building facades since the 1970s, resulting in significant energy savings. Additionally, as a result of EnEV 2002 implementation, energy consumption for building facades has gradually increased. The initial systems have reached the end of their useful life due to the durability of these composites, and an increasing amount of TICS waste has been generated in recent years. TICS are currently processed solely in waste incineration plants; no other method of recycling these devices exists. Due to technical constraints and the high calorific value of TICS, thermal disposal alone is not feasible. Additionally, because TICS systems are comprised of numerous components, significant resources will be wasted if they are not recycled properly. This study examines actual TICS waste that is technologically processed in order to recycle it based on its composition.}, language = {de} } @masterthesis{Shamsuzaman, type = {Bachelor Thesis}, author = {Shamsuzaman, Md}, title = {Engineering of an Algal Turf Scrubber (ATS) for phosphate removal from wastewater}, school = {Hochschule Rhein-Waal}, abstract = {With an increasing population around the world, there is a surge in wastewater generation as well as an eager demand for energy. Carbon dioxide and other pollutants are also released into the atmosphere when fossil fuels are burned for energy production. In order to reduce wastewater treatment costs and create energy, it is crucial to develop sustainable green strategies. Microalgae could be the best alternative to solve these problems. These can potentially reduce the cost and energy usage of treating wastewater compared to conventional wastewater treatment procedures. Phosphate is one of the critical elements in wastewater, which has to be minimized to a certain level in a wastewater treatment plant. Scientists have been researching cost-effective algal cultivation systems for a long time. In the early 90s, Adey developed the first Algal Turf Scrubber concept. This thesis investigates Algal Turf Scrubber (ATS) to produce microalgae biomass and remove nutrients from wastewater. In order to build an ATS, various techniques and equipment have been used. An ideal movement system has been created using MATLAB Simulink and Arduino. A 20W blue LED light was used on the basis of 09h:09h (Light : Dark). In this study, two algal turf scrubbers were constructed. External liquid phosphate was used with the Spoy Kanal water in order to increase the phosphate level, as the Spoy Kanal water contains a very low phosphate. On average, the rate of 0.65 mg/L per day phosphate and 0.41 mg/L per day nitrate removal were recorded in 12 days of operation}, language = {en} } @masterthesis{Wensor, type = {Bachelor Thesis}, author = {Wensor, Brianna}, title = {Start-up and operation of a continuous stirred tank reactor performing stable anammox process with Candidatus Brocadia fulgida}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-12695}, school = {Hochschule Rhein-Waal}, pages = {66}, abstract = {Nitrogen removal from wastewater is an energy and resource intense operation. In response, anaerobic ammonium oxidising (anammox) bacteria are being increasingly applied as a cost effective and sustainable wastewater treatment. Despite their utilisation worldwide, very little is understood about kinetic parameters and factors impacting their niche differentiation. The lack of enriched planktonic cultures is limiting further investigations into anammox bacteria and the optimisation of wastewater treatment. In this study, a Continuously Stirred Tank Reactor (CSTR) inoculated with Candidatus Brocadia fulgida to obtain an enriched planktonic culture. Ca. Brocadia fulgida was selected due to Ca. Brocadias widespread application in Wastewater Treatment Plants (WWTPs), and the lack of planktonic cultures of this anammox species. The cultivation of anammox bacteria is a time-consuming operation, due to the slow growth rate. This operation was conducted for 84 days, and variety of analytical and microbial techniques were used to monitor bioreactor performance and anammox bacteria enrichment. An analysis of consumption and production patterns was performed to investigate anammox metabolism. Changes in the microbial community were also assessed, which indicated a culture enriched in anammox bacteria. The establishment of a planktonic culture enriched in Ca. Brocadia fulgida in a CSTR was not achieved, and further research is needed in order to successfully apply this innovative approach to anammox bacteria cultivation.}, language = {en} }
