Both
of us are final year students who are currently studying in Singapore
Polytechnic, the School of Architecture and the Built Environment (ABE),
pursuing a Diploma in Environmental Management and Water Technology. Being
outdoor land and water sport enthusiasts, we both spend a considerable amount
of time interacting with our environment and we are thankful of having such
clean facilities for us to enjoy our activities. Furthermore, being students
involved in the environmental field, we are aware of the importance of taking
care of what Mother Nature has bestowed upon us. We feel that every individual
has a part to play, no matter how big or small one's contribution is. While our
proposal may not seem much, we hope that a small idea like ours will be the
start of creating a positive impact to the environment. This way, we can
not only ensure the sustainability of the environment but also continue to have
fun outdoors!
Industrial
discharge contains unwanted organic dyes such as Methylene Blue (MB).
The current conventional treatment method to remove this dye effectively
is by using granular activated carbon however its main drawback lies in
its high energy cost. Several other low-cost adsorbent materials, which
are also regarded as natural wastes by the society, were investigated
in their removal efficiency of this dye and they showed promising
results. Sewage
sludge, another type of natural waste, is a natural by-product of the
waste water treatment process, and it is reported to be the only waste
in Singapore with a 0% recycling rate. Hence, the objectives of our
project is to turn sludge into a potential value-added product by
determining if heated dried sludge is capable of removing Methylene Blue
in a water medium.
