dc.description.abstract | Water shortage issues have been growing concerns
in many cities around world in recent years,
especially in eastern cities of Australia. This paper
explores use of waste incineration energy
complemented by alternative energy for seawater
desalination for a drought stricken city in Eastern
Australia. Our research is motivated by the recent
successive severe drought conditions that hit many
Australian cities, compounded with an additional
strain from the fast growing population. While we
dump our waste into the Australian landscape, in
more densely populated cities including Vienna,
Austria, and a large number of cities in Japan, the
waste is incinerated to obtain thermal energy for
various purposes including heating and electricity
generation. The waste is used as a cheap fuel
source while reducing the amount of space needed
for landfill. The seawater desalination has been
successfully practiced for quite sometime
particularly in Middle Eastern counties. To deal
with increasing water shortage crisis, more cities
around the world have opted or are considering the
seawater desalination to complement their water
demand. At this time, to the best of our
knowledge, the combination of both - waste
incineration and seawater desalination - has not
been studied or implemented. Motivated by this
promising combination, we started investigating
the potential of seawater desalination powered by
waste incineration using the Gold Coast City,
Australia as a case study. If we can incinerate the
waste to power a desalination process, we reduce
water shortage, and at the same time reducing an
amount of landfill. The seawater desalination is an
expensive production process, but it ensures
continuation of fresh water supply in dry weather
conditions.
Our model follows a dynamic systems approach
with control theory as basic discipline. This
approach allows the observation of long-term
behaviour of a system and its dynamics, with its
effects more visible at a high level of resolution
than with statistical modelling. The model is implemented with modular hierarchical structure
in Matlab/Simulink. This allows gradual building
of the complexity into the model. We have
overcome a number of modelling difficulties
including lack of accurate dam catchment data by
incorporating other modelling techniques such as
artificial neural networks. We then incorporated
the mathematical model retrieved from the
artificial neural networks into our model. The
model presented in this paper is an extension and
refinement of our earlier model with integrated
specific sub-models derived from artificial neural
networks.
The focus of this work is on simulating the
possible amount of energy and the desalinated
water that can be generated by clean city waste
incineration. We do this while simulating the
increasing population, and their water demand. We
then calculate the additional amount of alternative
energy that would be required to complement the
waste incineration energy for producing sufficient
supply of desalinated water. In this paper we present the calibration of the
model, followed by a long-term experimental
simulation, while incorporating population growth,
with its growing fresh water demand and waste
generation. The result indicates that seawater
desalination by incinerating the waste itself alone
is able to supply over 40% of water demand
continuously throughout 50 simulated years as
shown in Figure 1. | |
