Modellierung und Implementierung von Regelungen einer Umkehrosmosanlage

Diplomarbeit aus dem Jahr 2006 im Fachbereich Informatik - Technische Informatik, Note: 1,3, Universität Mannheim, Sprache: Deutsch, Abstract: In the context of this diploma thesis the following tasks should be solved:

- to develop a mathematical model of a continuously working OSMO ECO reverse

osmosis plant of the company OSMO SISTEMI (Italy);

- to implement this mathematical model as an input/output system with assistance of

Matlab/Simulink/Stateflow;

- to validate the Matlab/Simulink/Stateflow model with the OSMO ECO reverse

osmosis plant;

- to test different controls at the model and discuss results.

Because of the influence of unforeseeable events these tasks were changed. It does

not become the OSMO ECO reverse osmosis plant specified above, but on the basis

fixed characteristics a new system was theoretically designed. The following must be

considered thereby: According to the possibility with only one reverse osmosis unit

from the dirty water (max. 10000 ppm TDS) get as much as possible pure water (TDS

< 150 ppm).

There are different kinds of RO units. Here, only two usually common types of RO¿

modules are considered: the hollow fiber module as well as the spiral wounded

module. The obtained simulation results as well as the model based controller design

carried out by using the model, which was developed in this work, are satisfactory

and open several perspectives for the future work. Because the plant was not

available during the development of this work, it was not possible to compare the

results of the simulation with the data from the real plant.
