Rudolf Herzog , Rehm Software Berg / Ravensburg. 9 S. (S. 94-102). Beitrag zum 1. Aachener Softwaretag in der Wasserwirtschaft a1, 2007, Aachen>. Zusammenfassung [des Autors] Die grundlegenden Ans{\"a}tze der beiden Modelle sind {\"a}hnlich. Der haupts{\"a}chliche Unterschied liegt darin, dass die Grenzwertmethode die Angabe einer Bodenart erfordert, die ihrerseits wieder Probleme verursachen kann. Es kann nicht davon ausgegangen werden, dass die Bodenarten homogen anliegen. Die ersatzweise Vorgabe einer f{\"u}r alle Einzugsgebiete einheitlichen Bodenart hilft da nicht wirklich weiter. Es stellt sich vielmehr die Frage, ob der zus{\"a}tzliche Aufwand eine signifikante Verbesserung des Ereignisses zur Folge hat. Der Vorteil der Grenzwertmethode liegt auf der Hand: Die Parameterwahl erm{\"o}glicht eine flexible Steuerung des Modells, in die Abflussbildung kann differenziert eingegriffen werden. Das NA-Geschehen kann weitgehend kalibriert werden. Es ist allerdings auch zu bedenken, dass die Flexibilit{\"a}t des Modells risikobehaftet ist - die Abflussbildung kann nach Belieben beeinflusst werden. Fazit: Flexibel in der Anwendung, bei NA-Messung empfehlenswert. Im Allgemeinen geringere Abflussmengen als Keser. Die Blackbox von Keser ist zwar nicht steuerbar, entzieht sich damit aber auch Wissensdefiziten und Manipulationseinfl{\"u}ssen. {\"U}ber Parameter und deren Auswirkungen muss nicht spekuliert werden. Wenn mehrere Personen mit dem Modell von Keser arbeiten, ergeben sich im Gegensatz zur Grenzwertmethode zwangsweise dieselben Ergebnisse - gleiche geometrische Oberfl{\"a}chendaten vorausgesetzt. Außerdem kommt Keser ohne die Bodenart aus. Fazit: Bei BFG >20\%, einfache Handhabung, geringer Aufwand. Gegen{\"u}ber der Grenzwertmethode (mittlere Verh{\"a}ltnisse) jedoch etwas h{\"o}here Abfl{\"u}sse. Das Programmpaket HYKAS der Fa. Rehm Software erm{\"o}glicht u.a. den Nachweis von Kanalnetzen und bietet in diesem Zusammenhang beide Modellans{\"a}tze zur Auswahl an. Der Programmanwender kann damit eine am Datenbestand bzw. an den Vorgaben des Auftraggebers ausgerichtete Modellauswahl treffen. Die realit{\"a}tsnahe Ermittlung der Oberfl{\"a}chenabfl{\"u}sse ist kompliziert. Weitere Unwegsamkeiten warten nach der Abflussbildung bei der Abflusskonzentration auf: Es ist z.B. die Festlegung der Fließl{\"a}nge auf der Oberfl{\"a}che erforderlich... Es ist noch ein weiter Weg bis zur Kl{\"a}ranlage.}, subject = {Entw{\"a}sserung }, language = {de} } @inproceedings{Kloecker2006, author = {Kl{\"o}cker, Alexander}, title = {Das Leitungsbauunternehmen - unternehmerische Strategie als Zukunftssicherung}, year = {2006}, abstract = {In: Alfha.net / Sektion Bauingenieurwesen: 1.

This study developed a conceptual model of a mainstream deammonification plant, designed for 30,000 P.E., considering possible solutions corresponding to the challenging mainstream conditions in Germany. In addition, the energy-saving potential, nitrogen elimination performance and construction-related costs of mainstream deammonification were compared to a conventional plant model, having a single-stage activated sludge process with upstream denitrification. The results revealed that an additional treatment step by combining chemical precipitation and ultra-fine screening is advantageous prior the mainstream deammonification. Hereby chemical oxygen demand (COD) can be reduced by 80\% so that the COD:N ratio can be reduced from 12 to 2.5. Laboratory experiments testing mainstream conditions of temperature (8-20°C), pH (6-9) and COD:N ratio (1-6) showed an achievable volumetric nitrogen removal rate (VNRR) of at least 50 gN/(m3∙d) for various deammonifying sludges from side stream deammonification systems in the state of North Rhine-Westphalia, Germany, where m3 denotes reactor volume. Assuming a retained Norganic content of 0.0035 kgNorg./(P.E.∙d) from the daily loads of N at carbon removal stage and a VNRR of 50 gN/(m3∙d) under mainstream conditions, a resident-specific reactor volume of 0.115 m3/(P.E.) is required for mainstream deammonification. This is in the same order of magnitude as the conventional activated sludge process, i.e., 0.173 m3/(P.E.) for an MWWTP of size class of 4. The conventional plant model yielded a total specific electricity demand of 35 kWh/(P.E.∙a) for the operation of the whole MWWTP and an energy recovery potential of 15.8 kWh/(P.E.∙a) through anaerobic digestion. In contrast, the developed mainstream deammonification model plant would require only a 21.5 kWh/(P.E.∙a) energy demand and result in 24 kWh/(P.E.∙a) energy recovery potential, enabling the mainstream deammonification model plant to be self-sufficient. The retrofitting costs for the implementation of mainstream deammonification in existing conventional MWWTPs are nearly negligible as the existing units like activated sludge reactors, aerators and monitoring technology are reusable. However, the mainstream deammonification must meet the performance requirement of VNRR of about 50 gN/(m3∙d) in this case.}, language = {en} } @article{LaumannKindmann2004, author = {Laumann, J{\"o}rg and Kindmann, Rolf}, title = {Computerorientierte L{\"o}sung von Stabilit{\"a}ts¬problemen im Bauwesen / Kindmann, R. ; Laumann, J.}, series = {Computer im Bauwesen : Festschrift zum 60.

This was achieved through concept design, dynamic thermal modelling and testing of a number of potentially viable systems and concepts. A significant programme of thermal simulation modelling was undertaken utilising the thermally equivalent slab (TES) concept to model the passive thermal capacity effect of profiled, composite metal floor decks. It is apparent from the modelling results that thermal mass is a highly complex phenomenon which is highly dependent upon building type, occupancy patterns, climate and many other aspects of the building design and servicing strategy. The ATM systems developed, both conceptually and for prototype testing, focussed on water-cooled composite slabs, the Cofradal floor system and the phase change material (PCM) Energain. In addition to laboratory testing of prototypes, whole building monitoring was undertaken at the Kubik building in Spain and the RWTH test building in Germany. Advanced thermal modelling was also undertaken to estimate the likely benefits of the ATM concept designs developed and for comparison with the test results. In addition to thermal testing, structural tests were conducted on composite floor specimens incorporating embedded water pipes.
