USM Student Invents Material To Rehabilitate Waste Water

26.05.2008
TECHNOLOGY FOR INDUSTRY: USM STUDENT INVENTS MATERIAL TO REHABILITATE WASTE WATER

Realising the importance of clean water for more than 27 million people in Malaysia, two USM students successfully produced a material which is able to absorb heavy metal from industrial waste water.

The product, called “mobilised Yeast” was created by Eka Anggraini Azuardi and Nazira Khabibor Rahman – both final year student from the USM Chemical Engineering Research Centre.

The product, is not only effective but also more economical, compared with the current method.

According to Eka Anggraini, the product was invention using the bio absorption method – by changing yeast which are used in food, as heavy metal absorption agent, in the waste water.

The yeast is produced in the shape of beads in cream colour. The beads would be mixed in the waste water which is to be treated.

When the heavy metal is absorbed, the beads will change to a blue-ish colour. The whole process will be repeated to ensure that the waste water is completely free of heavy metal, said Eka Anggraini.

The research started since June 2007 as the two students’ final year project.

Eka Anggraini said through the research and laboratory tests, “Immobilised Yeasts” showed very encouraging effectiveness.

Heavy metal consumed by our human body would not be able to flush out. It will remain in the body and may cause very serious health problems.

If the waste water does not go through proper treatment, it will have negative effects on human and other living creatures on the earth, said Eka Anggraini.

She added that, to date, there are only three ways to treat waste water, namely ion changing, membrane technology and abstractive chemical process.

Nevertheless, these methods are very expensive and often, bring negative consequences to the environment.

Optimistic with the research results, Eka Anggraini said “Mobilised Yeasts” also has the potential to be expanded to treat water for various other purposes.

“Mobilised Yeasts” is one of the 145 products taking part in the National Level Research and Innovation Competition 2008 in USM.

The competition lasted three days from 20 May 2008.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
