Aminuddin Muhamad Baki and four other young researchers, supervised by Professor Suhaimi Abdul Talib, of UiTM, found that having more organic content in sludge will generate more methane. Biogas composed of methane and carbon dioxide is a by-product of anaerobic bacterial decomposition of organic waste.
The organic waste content of municipal garbage and sewage means that they are important sources for biogas production. The methane content in biogas enables it to be used as engine fuel as well as enabling it to be converted into heat and electricity. An experimental study was completed that examined the relationship between the organic content of sludge and methane generation as the sludge progressed through mesophilic anaerobic digestion.
This study examined the organic content in sewage, represented by Biological Oxygen Demand (BOD) and Total Suspended Solid (TSS), in order to: (a) quantify the biogas and methane generation from sewage sludge; (b) determine the relationship between organic content and volume of methane; and (c) determine the pressure of biogas and the relationship between sludge volume and volume of biogas. It was found that there is potential for methane generation during anaerobic digestion even with a small volume of sludge.
The quality of sludge for methane generation is subject to the characteristics of the sludge. The organic content represented by BOD and TSS was measured in accordance to APHA standard methods (1998). Tests were conducted on wastewater from two treatment plants: the College of Mawar, UiTM, and IWK WWTP Section 7, Shah Alam. It was found that higher organic content in sewage sludge produced a higher volume of methane.Contacts:

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
