Data Source: ZID Abstracts
Main goal of the diploma thesis was the estimation of a water balance for sludge settling ponds of the sugar factory in Tulln for the period February 2004 to March 2005. First step was to analyse the available data. These data include the description of the operation cycle, as well as the climatic and the geographical circumstances. Next the input data for calculation of the real evapotranspiration is explained. Meterological date (precipitation, temperature, radiation and air humidity) are taken from the nearest govermental ZAMG observation site Langenlebarn. Some of the required data is recorded on the settling ponds Tulln themselves (e.g. flow measurement) The methodology of the water balance calculation and evapotranspiration determination is described. The actual evapotranspiration ¿ calculation for these settling ponds is based on the FAO ¿ guidelines (reference¿crop¿calculation, FAO publication No. 56 [ALLEN, et. al. 1998]). Some sludge samples of the settling ponds were taken and analyzed. By establishing a comprehensive water balance for the settling ponds two goals should be achieved: 1)all relevant parts of the water cycle are considered and 2)an easier approach for the future is proposed.
